Customer Reviews

Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.
 
Terrible 
This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.
 
Frustrated user 
I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!
 
No iPhone 11 update 
I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Please do the new version to work with iPhone 11 
Please do the new version please
 
No longer updated? 
While I realize many have upgraded to the G6, I quite enjoy my G5. However, the constant “functionality” messages I have with the updated iOS version plus the lack of complications for my recent upgrade to a series 5 Apple Watch makes me wonder if Dexcom is forcing the upgrade.
 
Great product, horrible support. 
I’ve been very happy with the product itself, but they company support has been horrible. They generally refuse to provide support by email and demand you call them on the phone, no matter how many times you specify a phone call is difficult for you. This company has zero concern For anyone with audible issues on a phone and flat out refuses to accommodate phone impaired people by email.
 
Annoyed 
Please fix the bugs that make you delete and reinstall the app. I need this for my daughter. It’s annoying that you have to delete and reinstall every 2days.
 
crashes 
The app has crashed 6 times in the past 2 weeks, it causes you to lose everything, and you have to repair the transmitter. All it says on the screen is the app has stopped working, delete the app and reinstall
 
App incompatible with IOS 13.3 
Update your app to keep up with operating system updates. This is a basic requirement of your service!
 
App not working with iOS 13.3 
Since updating my phone’s iOS version, the app no longer functions properly. It has slowed my phone down to a crawl (I know it is the Dexcom app because when I delete it my phone is fine). Also, the app makes me delete and re-download if I restart my phone. Do not download iOS 13.3! Hopefully they will make their app compatible soon.
 
App keeps crashing, no longer compatible with IOS 
I want to start by saying that for about the first year, I LOVED this app. It has made my life so much easier being able to glance at my phone or my Apple Watch and know exactly what my blood sugar is. However, since the latest iOS update, the app keeps crashing and forcing me to delete, redownload, and re pair my transmitter. If I’m lucky I get a day or two out of the app before it happens all over again. Sometimes this crash happens in the middle of the night causing me to miss extremely important alerts such as urgent low glucose levels. This isn’t just inconvenient, it’s dangerous for those relying on the app for important alerts such as this.
 
Frustrated 
This app not supported by iOS version 13.3. My husband can no longer track his blood glucose levels using this CGM with his phone. I feel like we had something that really worked and it got yanked away!
 
Crashing 
App keeps crashing! I’ve had to and reinstall at least 3 times this week. What is up???
 
Unhappy 
For the last several months I have had to delete my app at least every other day because it gives me an error saying it is no longer working. That is very inconvenient and annoying especially since I have to take my transmitter out of my sensor.
 
App Fails 
App used to work great, but in the last 2 months it has failed several times. Make sure you write down the serial number of your transmitter so you can have it when the app fails.
 
It works sometimes 
It works .. sometimes .. they did an update an now anytime my battery is low the whole app needs to be deleted redownloaded , then have to enter the transmitter info all back in which is really incovient when out
 
When are u fixing app for new version iOS?? 
When are you guys fixing dexcom g5 for new ios version???
 
Does not work with iPhone 11 
You must be kidding ... cmon Dexcom, get with it.
 
Crashes weekly! 
Keeps crashing. Having to uninstall and reinstall... Please fix! This is our life-line!
 
App is not working!!!! 
The app keeps notifying me that “the DExcom G5 app is no longer working, please delete the app and re download it” ive done this twice now and had to re connect the transmitter and it just happened again!! This is getting aggravating and getting in the way of my blood sugar control.
 
I’m a diabetic 
The app crashes and says The Dexcom Mobile app is no longer working delete it and reinstall worst app crashing I ever saw it’s happened 10 times in like 3 months
 
Is this app available for my G6 
I want to use this mobile app but it won’t work with my G6. The only app I find in the play store is for a simulator and DexCom follow. Is there a DexCom mobile app for the G6?
 
Was good....but to many errors! 
The app keeps “losing connection” then makes you delete and re-download.... would be fine if you didn’t have to recalibrate the sensor witch takes 2 hours...... 👎 they need to fix this and make it connect faster because 2 hours is NOT acceptable when a user can drop to a dangerous glucose level in less then 30 min..🤦🏻‍♂️ also you can NOT turn off all notifications.... it overrides your set volume setting and SCREAMS at you until its acknowledged.. Very embarrassing for the user and unprofessional... very disappointed in the last few updates, especially for how much you have to pay for the product.... I would NOT recommend until the issues are seriously addressed... is NOT safe or reliable.
 
Need to fix NOW 
As a type 1 diabetic, for 15+ years, I am reliant on try dexcom. Unfortunately the past two months have been problematic as the app continues to pop up with the idea that I must DELETE AND REDOWNLOAD the application. This is the fourth time, at least, that this has happened. When this happens it makes me use a brand new sensor EVERY time. I’m not sure what the app issue is. It seems to happen if my phone died periodically but had also happened in the middle of the day with normal phone life. I am only issued enough sensors per month and I use this in conjunction to my Omnipod. If it doesn’t shape up, It may cause me to pursue another system.
 
Bugs 
Works well but every few weeks it says the app isn’t functioning properly and I need to redownload. Very annoying. What’s good guys?
 
Known Issues, No Update 
Reached out to Dexcom about the G5 reading issues in November. They are aware that the app is no longer working properly since the latest iOS update, but have not updated it in over 7 months. If support was supposed to end (no official word on this yet), then they should have announced it via the app. Instead, they’ve abandoned their G5 customers.
 
Needs an update yesterday 
My app hadn’t been working for almost a month now since the latest iPhone update. I have not had my sensor on for that long and that’s not good. Please update the app so I can finally have my sensor back on and feeling better then I do now.
 
Dexcom G5 apple app 
The Dexcom G5 app is 7 months old. In first week of January my Apple phone was upgraded to iOS 13.3.1 and the Dexcom G5 app does not work on my phone. When called Dexcom Tech Support early last month was told the G5 is not compatible with that iPhone upgrade. When asked when Dexcom would update the app was told 3 to 6 months. Would not recommend Dexcom to any diabetics due to poor support.
 
Yehaaaaaa 
Works great and I love it can’t wait for the G6 I will miss you G5 thanks for the good times DEXCOM RULES
 
Lose transmission 
I love having this on my phone instead of carrying the monitor. I am reinstalling this app again since it keeps loosing connection and unable to transmit. I can turn on the monitor and it’s reading just fine. I have an IPhone 10x.
 
You are endangering lives. 
Why does this app still not support iOS 13? Why did the developers not warn diabetics before they made the irreversible decision to upgrade to the new iOS? People depend on this software to make crucial medical decisions every day. Why is it still not working? Fix it, Dexcom. Assign the budget. Hire new developers. Do what you need to do to fix this. This is literally your business and it is your responsibility.
 
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬 
Fix your bloody app!
 
App is TERRIBLE 
The app for the sensor is AWFUL. It and makes the functionality of the sensor almost impossible. It crashes multiple times a day and you have to delete and reinstall. Tech support is zero help and for the last 8 months they keep blaming the iPhone software update and saying they’re working on it. I was on a cruise with hardly any internet and my app crashed. For over 24 hours, I didn’t have access to my blood sugars because I couldn’t reinstall. The constant crashing puts you at risk! Currently about to ditch the Dexcom all together and go with another more reliable company.
 
Not great 
At night I like to use my receiver not my phone so I usually turn off my Dexcom app. But even when I swipe up this app to close it, it still runs in the background - so this app on my phone wakes me up if I’m low or high in the middle night. I have to delete this app and redownload it about every 2 days. Very frustrating.
 
Great when it works 
I just downloaded this app because my sons receiver messed up and our insurance want pay for another one. We decided to download the Dexcom app on his phone and the follow app on mine so I can watch what’s going on since this is new to us. Well his Dexcom app isn’t working and my follow app isn’t working either of course.
 
Always disconnects 
It says signal loss for periods of 30-90 minutes at least twice a day, regardless of actual signal strength or connection. Additionally, I don’t like how notifications are loud and can override the iPhone if you turn them off in settings.
 
Please FIX LANDSCAPE IMAGE! 
Your 3rd screen in the app above has been changed BADLY! When I turn my phone landscape and run my fingers across the values in the middle, IT COVERS UP THE TIME AND DATE-STAMP! My previous versions of Dexcom G5 app NEVER PERFORMED THIS WAY! I have been using the G5 since Jan, 2017!
 
Need message history 
This app works fine giving me the glucose level information I need. Its problem is it does not keep a long of the screen alerts it presents. The worst case is the transmitter dying message it pops up there is no way to retrieve the information and you have to wait until it is a week too late to order the replacement. Even a status on the transmitter information screen would work in that case.

Your 3rd screen in the app above has been changed BADLY! When I turn my phone landscape and run my fingers across the values in the middle, IT COVERS UP THE TIME AND DATE-STAMP! My previous versions of Dexcom G5 app NEVER PERFORMED THIS WAY! I have been using the G5 since Jan, 2017!
 
Need message history 
This app works fine giving me the glucose level information I need. Its problem is it does not keep a long of the screen alerts it presents. The worst case is the transmitter dying message it pops up there is no way to retrieve the information and you have to wait until it is a week too late to order the replacement. Even a status on the transmitter information screen would work in that case.
 
Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.
 
Terrible 
This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.
 
Frustrated user 
I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!
 
No iPhone 11 update 
I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Please do the new version to work with iPhone 11 
Please do the new version please
 
No longer updated? 
While I realize many have upgraded to the G6, I quite enjoy my G5. However, the constant “functionality” messages I have with the updated iOS version plus the lack of complications for my recent upgrade to a series 5 Apple Watch makes me wonder if Dexcom is forcing the upgrade.
 
Great product, horrible support. 
I’ve been very happy with the product itself, but they company support has been horrible. They generally refuse to provide support by email and demand you call them on the phone, no matter how many times you specify a phone call is difficult for you. This company has zero concern For anyone with audible issues on a phone and flat out refuses to accommodate phone impaired people by email.
 
Annoyed 
Please fix the bugs that make you delete and reinstall the app. I need this for my daughter. It’s annoying that you have to delete and reinstall every 2days.
 
crashes 
The app has crashed 6 times in the past 2 weeks, it causes you to lose everything, and you have to repair the transmitter. All it says on the screen is the app has stopped working, delete the app and reinstall
 
App incompatible with IOS 13.3 
Update your app to keep up with operating system updates. This is a basic requirement of your service!
 
App not working with iOS 13.3 
Since updating my phone’s iOS version, the app no longer functions properly. It has slowed my phone down to a crawl (I know it is the Dexcom app because when I delete it my phone is fine). Also, the app makes me delete and re-download if I restart my phone. Do not download iOS 13.3! Hopefully they will make their app compatible soon.
 
App keeps crashing, no longer compatible with IOS 
I want to start by saying that for about the first year, I LOVED this app. It has made my life so much easier being able to glance at my phone or my Apple Watch and know exactly what my blood sugar is. However, since the latest iOS update, the app keeps crashing and forcing me to delete, redownload, and re pair my transmitter. If I’m lucky I get a day or two out of the app before it happens all over again. Sometimes this crash happens in the middle of the night causing me to miss extremely important alerts such as urgent low glucose levels. This isn’t just inconvenient, it’s dangerous for those relying on the app for important alerts such as this.
 
Frustrated 
This app not supported by iOS version 13.3. My husband can no longer track his blood glucose levels using this CGM with his phone. I feel like we had something that really worked and it got yanked away!
 
Crashing 
App keeps crashing! I’ve had to and reinstall at least 3 times this week. What is up???
 
Unhappy 
For the last several months I have had to delete my app at least every other day because it gives me an error saying it is no longer working. That is very inconvenient and annoying especially since I have to take my transmitter out of my sensor.
 
App Fails 
App used to work great, but in the last 2 months it has failed several times. Make sure you write down the serial number of your transmitter so you can have it when the app fails.
 
It works sometimes 
It works .. sometimes .. they did an update an now anytime my battery is low the whole app needs to be deleted redownloaded , then have to enter the transmitter info all back in which is really incovient when out
 
When are u fixing app for new version iOS?? 
When are you guys fixing dexcom g5 for new ios version???
 
Does not work with iPhone 11 
You must be kidding ... cmon Dexcom, get with it.
 
Crashes weekly! 
Keeps crashing. Having to uninstall and reinstall... Please fix! This is our life-line!
 
App is not working!!!! 
The app keeps notifying me that “the DExcom G5 app is no longer working, please delete the app and re download it” ive done this twice now and had to re connect the transmitter and it just happened again!! This is getting aggravating and getting in the way of my blood sugar control.
 
I’m a diabetic 
The app crashes and says The Dexcom Mobile app is no longer working delete it and reinstall worst app crashing I ever saw it’s happened 10 times in like 3 months
 
Is this app available for my G6 
I want to use this mobile app but it won’t work with my G6. The only app I find in the play store is for a simulator and DexCom follow. Is there a DexCom mobile app for the G6?
 
Was good....but to many errors! 
The app keeps “losing connection” then makes you delete and re-download.... would be fine if you didn’t have to recalibrate the sensor witch takes 2 hours...... 👎 they need to fix this and make it connect faster because 2 hours is NOT acceptable when a user can drop to a dangerous glucose level in less then 30 min..🤦🏻‍♂️ also you can NOT turn off all notifications.... it overrides your set volume setting and SCREAMS at you until its acknowledged.. Very embarrassing for the user and unprofessional... very disappointed in the last few updates, especially for how much you have to pay for the product.... I would NOT recommend until the issues are seriously addressed... is NOT safe or reliable.
 
Need to fix NOW 
As a type 1 diabetic, for 15+ years, I am reliant on try dexcom. Unfortunately the past two months have been problematic as the app continues to pop up with the idea that I must DELETE AND REDOWNLOAD the application. This is the fourth time, at least, that this has happened. When this happens it makes me use a brand new sensor EVERY time. I’m not sure what the app issue is. It seems to happen if my phone died periodically but had also happened in the middle of the day with normal phone life. I am only issued enough sensors per month and I use this in conjunction to my Omnipod. If it doesn’t shape up, It may cause me to pursue another system.
 
Bugs 
Works well but every few weeks it says the app isn’t functioning properly and I need to redownload. Very annoying. What’s good guys?
 
Known Issues, No Update 
Reached out to Dexcom about the G5 reading issues in November. They are aware that the app is no longer working properly since the latest iOS update, but have not updated it in over 7 months. If support was supposed to end (no official word on this yet), then they should have announced it via the app. Instead, they’ve abandoned their G5 customers.
 
Needs an update yesterday 
My app hadn’t been working for almost a month now since the latest iPhone update. I have not had my sensor on for that long and that’s not good. Please update the app so I can finally have my sensor back on and feeling better then I do now.
 
Dexcom G5 apple app 
The Dexcom G5 app is 7 months old. In first week of January my Apple phone was upgraded to iOS 13.3.1 and the Dexcom G5 app does not work on my phone. When called Dexcom Tech Support early last month was told the G5 is not compatible with that iPhone upgrade. When asked when Dexcom would update the app was told 3 to 6 months. Would not recommend Dexcom to any diabetics due to poor support.
 
Yehaaaaaa 
Works great and I love it can’t wait for the G6 I will miss you G5 thanks for the good times DEXCOM RULES
 
Lose transmission 
I love having this on my phone instead of carrying the monitor. I am reinstalling this app again since it keeps loosing connection and unable to transmit. I can turn on the monitor and it’s reading just fine. I have an IPhone 10x.
 
You are endangering lives. 
Why does this app still not support iOS 13? Why did the developers not warn diabetics before they made the irreversible decision to upgrade to the new iOS? People depend on this software to make crucial medical decisions every day. Why is it still not working? Fix it, Dexcom. Assign the budget. Hire new developers. Do what you need to do to fix this. This is literally your business and it is your responsibility.
 
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬 
Fix your bloody app!
 
App is TERRIBLE 
The app for the sensor is AWFUL. It and makes the functionality of the sensor almost impossible. It crashes multiple times a day and you have to delete and reinstall. Tech support is zero help and for the last 8 months they keep blaming the iPhone software update and saying they’re working on it. I was on a cruise with hardly any internet and my app crashed. For over 24 hours, I didn’t have access to my blood sugars because I couldn’t reinstall. The constant crashing puts you at risk! Currently about to ditch the Dexcom all together and go with another more reliable company.
 
Not great 
At night I like to use my receiver not my phone so I usually turn off my Dexcom app. But even when I swipe up this app to close it, it still runs in the background - so this app on my phone wakes me up if I’m low or high in the middle night. I have to delete this app and redownload it about every 2 days. Very frustrating.
 
Great when it works 
I just downloaded this app because my sons receiver messed up and our insurance want pay for another one. We decided to download the Dexcom app on his phone and the follow app on mine so I can watch what’s going on since this is new to us. Well his Dexcom app isn’t working and my follow app isn’t working either of course.
 
Always disconnects 
It says signal loss for periods of 30-90 minutes at least twice a day, regardless of actual signal strength or connection. Additionally, I don’t like how notifications are loud and can override the iPhone if you turn them off in settings.

This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.
 
Frustrated user 
I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!
 
No iPhone 11 update 
I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Please do the new version to work with iPhone 11 
Please do the new version please
 
No longer updated? 
While I realize many have upgraded to the G6, I quite enjoy my G5. However, the constant “functionality” messages I have with the updated iOS version plus the lack of complications for my recent upgrade to a series 5 Apple Watch makes me wonder if Dexcom is forcing the upgrade.
 
Great product, horrible support. 
I’ve been very happy with the product itself, but they company support has been horrible. They generally refuse to provide support by email and demand you call them on the phone, no matter how many times you specify a phone call is difficult for you. This company has zero concern For anyone with audible issues on a phone and flat out refuses to accommodate phone impaired people by email.
 
Annoyed 
Please fix the bugs that make you delete and reinstall the app. I need this for my daughter. It’s annoying that you have to delete and reinstall every 2days.
 
crashes 
The app has crashed 6 times in the past 2 weeks, it causes you to lose everything, and you have to repair the transmitter. All it says on the screen is the app has stopped working, delete the app and reinstall
 
App incompatible with IOS 13.3 
Update your app to keep up with operating system updates. This is a basic requirement of your service!
 
App not working with iOS 13.3 
Since updating my phone’s iOS version, the app no longer functions properly. It has slowed my phone down to a crawl (I know it is the Dexcom app because when I delete it my phone is fine). Also, the app makes me delete and re-download if I restart my phone. Do not download iOS 13.3! Hopefully they will make their app compatible soon.
 
App keeps crashing, no longer compatible with IOS 
I want to start by saying that for about the first year, I LOVED this app. It has made my life so much easier being able to glance at my phone or my Apple Watch and know exactly what my blood sugar is. However, since the latest iOS update, the app keeps crashing and forcing me to delete, redownload, and re pair my transmitter. If I’m lucky I get a day or two out of the app before it happens all over again. Sometimes this crash happens in the middle of the night causing me to miss extremely important alerts such as urgent low glucose levels. This isn’t just inconvenient, it’s dangerous for those relying on the app for important alerts such as this.
 
Frustrated 
This app not supported by iOS version 13.3. My husband can no longer track his blood glucose levels using this CGM with his phone. I feel like we had something that really worked and it got yanked away!
 
Crashing 
App keeps crashing! I’ve had to and reinstall at least 3 times this week. What is up???
 
Unhappy 
For the last several months I have had to delete my app at least every other day because it gives me an error saying it is no longer working. That is very inconvenient and annoying especially since I have to take my transmitter out of my sensor.
 
App Fails 
App used to work great, but in the last 2 months it has failed several times. Make sure you write down the serial number of your transmitter so you can have it when the app fails.
 
It works sometimes 
It works .. sometimes .. they did an update an now anytime my battery is low the whole app needs to be deleted redownloaded , then have to enter the transmitter info all back in which is really incovient when out
 
When are u fixing app for new version iOS?? 
When are you guys fixing dexcom g5 for new ios version???
 
Does not work with iPhone 11 
You must be kidding ... cmon Dexcom, get with it.
 
Crashes weekly! 
Keeps crashing. Having to uninstall and reinstall... Please fix! This is our life-line!
 
App is not working!!!! 
The app keeps notifying me that “the DExcom G5 app is no longer working, please delete the app and re download it” ive done this twice now and had to re connect the transmitter and it just happened again!! This is getting aggravating and getting in the way of my blood sugar control.
 
I’m a diabetic 
The app crashes and says The Dexcom Mobile app is no longer working delete it and reinstall worst app crashing I ever saw it’s happened 10 times in like 3 months
 
Is this app available for my G6 
I want to use this mobile app but it won’t work with my G6. The only app I find in the play store is for a simulator and DexCom follow. Is there a DexCom mobile app for the G6?
 
Was good....but to many errors! 
The app keeps “losing connection” then makes you delete and re-download.... would be fine if you didn’t have to recalibrate the sensor witch takes 2 hours...... 👎 they need to fix this and make it connect faster because 2 hours is NOT acceptable when a user can drop to a dangerous glucose level in less then 30 min..🤦🏻‍♂️ also you can NOT turn off all notifications.... it overrides your set volume setting and SCREAMS at you until its acknowledged.. Very embarrassing for the user and unprofessional... very disappointed in the last few updates, especially for how much you have to pay for the product.... I would NOT recommend until the issues are seriously addressed... is NOT safe or reliable.
 
Need to fix NOW 
As a type 1 diabetic, for 15+ years, I am reliant on try dexcom. Unfortunately the past two months have been problematic as the app continues to pop up with the idea that I must DELETE AND REDOWNLOAD the application. This is the fourth time, at least, that this has happened. When this happens it makes me use a brand new sensor EVERY time. I’m not sure what the app issue is. It seems to happen if my phone died periodically but had also happened in the middle of the day with normal phone life. I am only issued enough sensors per month and I use this in conjunction to my Omnipod. If it doesn’t shape up, It may cause me to pursue another system.
 
Bugs 
Works well but every few weeks it says the app isn’t functioning properly and I need to redownload. Very annoying. What’s good guys?
 
Known Issues, No Update 
Reached out to Dexcom about the G5 reading issues in November. They are aware that the app is no longer working properly since the latest iOS update, but have not updated it in over 7 months. If support was supposed to end (no official word on this yet), then they should have announced it via the app. Instead, they’ve abandoned their G5 customers.
 
Needs an update yesterday 
My app hadn’t been working for almost a month now since the latest iPhone update. I have not had my sensor on for that long and that’s not good. Please update the app so I can finally have my sensor back on and feeling better then I do now.
 
Dexcom G5 apple app 
The Dexcom G5 app is 7 months old. In first week of January my Apple phone was upgraded to iOS 13.3.1 and the Dexcom G5 app does not work on my phone. When called Dexcom Tech Support early last month was told the G5 is not compatible with that iPhone upgrade. When asked when Dexcom would update the app was told 3 to 6 months. Would not recommend Dexcom to any diabetics due to poor support.
 
Yehaaaaaa 
Works great and I love it can’t wait for the G6 I will miss you G5 thanks for the good times DEXCOM RULES
 
Lose transmission 
I love having this on my phone instead of carrying the monitor. I am reinstalling this app again since it keeps loosing connection and unable to transmit. I can turn on the monitor and it’s reading just fine. I have an IPhone 10x.
 
You are endangering lives. 
Why does this app still not support iOS 13? Why did the developers not warn diabetics before they made the irreversible decision to upgrade to the new iOS? People depend on this software to make crucial medical decisions every day. Why is it still not working? Fix it, Dexcom. Assign the budget. Hire new developers. Do what you need to do to fix this. This is literally your business and it is your responsibility.
 
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬 
Fix your bloody app!
 
App is TERRIBLE 
The app for the sensor is AWFUL. It and makes the functionality of the sensor almost impossible. It crashes multiple times a day and you have to delete and reinstall. Tech support is zero help and for the last 8 months they keep blaming the iPhone software update and saying they’re working on it. I was on a cruise with hardly any internet and my app crashed. For over 24 hours, I didn’t have access to my blood sugars because I couldn’t reinstall. The constant crashing puts you at risk! Currently about to ditch the Dexcom all together and go with another more reliable company.
 
Not great 
At night I like to use my receiver not my phone so I usually turn off my Dexcom app. But even when I swipe up this app to close it, it still runs in the background - so this app on my phone wakes me up if I’m low or high in the middle night. I have to delete this app and redownload it about every 2 days. Very frustrating.
 
Great when it works 
I just downloaded this app because my sons receiver messed up and our insurance want pay for another one. We decided to download the Dexcom app on his phone and the follow app on mine so I can watch what’s going on since this is new to us. Well his Dexcom app isn’t working and my follow app isn’t working either of course.
 
Always disconnects 
It says signal loss for periods of 30-90 minutes at least twice a day, regardless of actual signal strength or connection. Additionally, I don’t like how notifications are loud and can override the iPhone if you turn them off in settings.
 
Please FIX LANDSCAPE IMAGE! 
Your 3rd screen in the app above has been changed BADLY! When I turn my phone landscape and run my fingers across the values in the middle, IT COVERS UP THE TIME AND DATE-STAMP! My previous versions of Dexcom G5 app NEVER PERFORMED THIS WAY! I have been using the G5 since Jan, 2017!
 
Need message history 
This app works fine giving me the glucose level information I need. Its problem is it does not keep a long of the screen alerts it presents. The worst case is the transmitter dying message it pops up there is no way to retrieve the information and you have to wait until it is a week too late to order the replacement. Even a status on the transmitter information screen would work in that case.
 
Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.

Dropped connection 
At first I really liked this app and the switch to a phone/platform that supported the app was worth it; as it allowed me to carry one less controller and I was able to share information with my spouse as advertised. After a couple weeks of sharing my spouse no longer got information. The app tells me “no internet connection” and the Follow app on my spouse’s phone says “Dexcom server error”. It will not allow the current follower to be deleted or a new follower to be added. Now four weeks into using the Dexcom G5 mobile app it no longer gives me readings either! I have had to go back to using the old CGM. I am getting an error saying I am not connected to the internet when trying to log into the Dexcom G5 app. The first mention of this type of error I found was from 2017 on Google and Dexcom is still having the connectivity issue in 2019.

I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!
 
No iPhone 11 update 
I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Please do the new version to work with iPhone 11 
Please do the new version please
 
No longer updated? 
While I realize many have upgraded to the G6, I quite enjoy my G5. However, the constant “functionality” messages I have with the updated iOS version plus the lack of complications for my recent upgrade to a series 5 Apple Watch makes me wonder if Dexcom is forcing the upgrade.
 
Great product, horrible support. 
I’ve been very happy with the product itself, but they company support has been horrible. They generally refuse to provide support by email and demand you call them on the phone, no matter how many times you specify a phone call is difficult for you. This company has zero concern For anyone with audible issues on a phone and flat out refuses to accommodate phone impaired people by email.
 
Annoyed 
Please fix the bugs that make you delete and reinstall the app. I need this for my daughter. It’s annoying that you have to delete and reinstall every 2days.
 
crashes 
The app has crashed 6 times in the past 2 weeks, it causes you to lose everything, and you have to repair the transmitter. All it says on the screen is the app has stopped working, delete the app and reinstall
 
App incompatible with IOS 13.3 
Update your app to keep up with operating system updates. This is a basic requirement of your service!
 
App not working with iOS 13.3 
Since updating my phone’s iOS version, the app no longer functions properly. It has slowed my phone down to a crawl (I know it is the Dexcom app because when I delete it my phone is fine). Also, the app makes me delete and re-download if I restart my phone. Do not download iOS 13.3! Hopefully they will make their app compatible soon.
 
App keeps crashing, no longer compatible with IOS 
I want to start by saying that for about the first year, I LOVED this app. It has made my life so much easier being able to glance at my phone or my Apple Watch and know exactly what my blood sugar is. However, since the latest iOS update, the app keeps crashing and forcing me to delete, redownload, and re pair my transmitter. If I’m lucky I get a day or two out of the app before it happens all over again. Sometimes this crash happens in the middle of the night causing me to miss extremely important alerts such as urgent low glucose levels. This isn’t just inconvenient, it’s dangerous for those relying on the app for important alerts such as this.
 
Frustrated 
This app not supported by iOS version 13.3. My husband can no longer track his blood glucose levels using this CGM with his phone. I feel like we had something that really worked and it got yanked away!
 
Crashing 
App keeps crashing! I’ve had to and reinstall at least 3 times this week. What is up???
 
Unhappy 
For the last several months I have had to delete my app at least every other day because it gives me an error saying it is no longer working. That is very inconvenient and annoying especially since I have to take my transmitter out of my sensor.
 
App Fails 
App used to work great, but in the last 2 months it has failed several times. Make sure you write down the serial number of your transmitter so you can have it when the app fails.
 
It works sometimes 
It works .. sometimes .. they did an update an now anytime my battery is low the whole app needs to be deleted redownloaded , then have to enter the transmitter info all back in which is really incovient when out
 
When are u fixing app for new version iOS?? 
When are you guys fixing dexcom g5 for new ios version???
 
Does not work with iPhone 11 
You must be kidding ... cmon Dexcom, get with it.
 
Crashes weekly! 
Keeps crashing. Having to uninstall and reinstall... Please fix! This is our life-line!
 
App is not working!!!! 
The app keeps notifying me that “the DExcom G5 app is no longer working, please delete the app and re download it” ive done this twice now and had to re connect the transmitter and it just happened again!! This is getting aggravating and getting in the way of my blood sugar control.
 
I’m a diabetic 
The app crashes and says The Dexcom Mobile app is no longer working delete it and reinstall worst app crashing I ever saw it’s happened 10 times in like 3 months
 
Is this app available for my G6 
I want to use this mobile app but it won’t work with my G6. The only app I find in the play store is for a simulator and DexCom follow. Is there a DexCom mobile app for the G6?
 
Was good....but to many errors! 
The app keeps “losing connection” then makes you delete and re-download.... would be fine if you didn’t have to recalibrate the sensor witch takes 2 hours...... 👎 they need to fix this and make it connect faster because 2 hours is NOT acceptable when a user can drop to a dangerous glucose level in less then 30 min..🤦🏻‍♂️ also you can NOT turn off all notifications.... it overrides your set volume setting and SCREAMS at you until its acknowledged.. Very embarrassing for the user and unprofessional... very disappointed in the last few updates, especially for how much you have to pay for the product.... I would NOT recommend until the issues are seriously addressed... is NOT safe or reliable.
 
Need to fix NOW 
As a type 1 diabetic, for 15+ years, I am reliant on try dexcom. Unfortunately the past two months have been problematic as the app continues to pop up with the idea that I must DELETE AND REDOWNLOAD the application. This is the fourth time, at least, that this has happened. When this happens it makes me use a brand new sensor EVERY time. I’m not sure what the app issue is. It seems to happen if my phone died periodically but had also happened in the middle of the day with normal phone life. I am only issued enough sensors per month and I use this in conjunction to my Omnipod. If it doesn’t shape up, It may cause me to pursue another system.
 
Bugs 
Works well but every few weeks it says the app isn’t functioning properly and I need to redownload. Very annoying. What’s good guys?
 
Known Issues, No Update 
Reached out to Dexcom about the G5 reading issues in November. They are aware that the app is no longer working properly since the latest iOS update, but have not updated it in over 7 months. If support was supposed to end (no official word on this yet), then they should have announced it via the app. Instead, they’ve abandoned their G5 customers.
 
Needs an update yesterday 
My app hadn’t been working for almost a month now since the latest iPhone update. I have not had my sensor on for that long and that’s not good. Please update the app so I can finally have my sensor back on and feeling better then I do now.
 
Dexcom G5 apple app 
The Dexcom G5 app is 7 months old. In first week of January my Apple phone was upgraded to iOS 13.3.1 and the Dexcom G5 app does not work on my phone. When called Dexcom Tech Support early last month was told the G5 is not compatible with that iPhone upgrade. When asked when Dexcom would update the app was told 3 to 6 months. Would not recommend Dexcom to any diabetics due to poor support.
 
Yehaaaaaa 
Works great and I love it can’t wait for the G6 I will miss you G5 thanks for the good times DEXCOM RULES
 
Lose transmission 
I love having this on my phone instead of carrying the monitor. I am reinstalling this app again since it keeps loosing connection and unable to transmit. I can turn on the monitor and it’s reading just fine. I have an IPhone 10x.
 
You are endangering lives. 
Why does this app still not support iOS 13? Why did the developers not warn diabetics before they made the irreversible decision to upgrade to the new iOS? People depend on this software to make crucial medical decisions every day. Why is it still not working? Fix it, Dexcom. Assign the budget. Hire new developers. Do what you need to do to fix this. This is literally your business and it is your responsibility.
 
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬 
Fix your bloody app!
 
App is TERRIBLE 
The app for the sensor is AWFUL. It and makes the functionality of the sensor almost impossible. It crashes multiple times a day and you have to delete and reinstall. Tech support is zero help and for the last 8 months they keep blaming the iPhone software update and saying they’re working on it. I was on a cruise with hardly any internet and my app crashed. For over 24 hours, I didn’t have access to my blood sugars because I couldn’t reinstall. The constant crashing puts you at risk! Currently about to ditch the Dexcom all together and go with another more reliable company.
 
Not great 
At night I like to use my receiver not my phone so I usually turn off my Dexcom app. But even when I swipe up this app to close it, it still runs in the background - so this app on my phone wakes me up if I’m low or high in the middle night. I have to delete this app and redownload it about every 2 days. Very frustrating.
 
Great when it works 
I just downloaded this app because my sons receiver messed up and our insurance want pay for another one. We decided to download the Dexcom app on his phone and the follow app on mine so I can watch what’s going on since this is new to us. Well his Dexcom app isn’t working and my follow app isn’t working either of course.
 
Always disconnects 
It says signal loss for periods of 30-90 minutes at least twice a day, regardless of actual signal strength or connection. Additionally, I don’t like how notifications are loud and can override the iPhone if you turn them off in settings.
 
Please FIX LANDSCAPE IMAGE! 
Your 3rd screen in the app above has been changed BADLY! When I turn my phone landscape and run my fingers across the values in the middle, IT COVERS UP THE TIME AND DATE-STAMP! My previous versions of Dexcom G5 app NEVER PERFORMED THIS WAY! I have been using the G5 since Jan, 2017!
 
Dropped connection 
At first I really liked this app and the switch to a phone/platform that supported the app was worth it; as it allowed me to carry one less controller and I was able to share information with my spouse as advertised. After a couple weeks of sharing my spouse no longer got information. The app tells me “no internet connection” and the Follow app on my spouse’s phone says “Dexcom server error”. It will not allow the current follower to be deleted or a new follower to be added. Now four weeks into using the Dexcom G5 mobile app it no longer gives me readings either! I have had to go back to using the old CGM. I am getting an error saying I am not connected to the internet when trying to log into the Dexcom G5 app. The first mention of this type of error I found was from 2017 on Google and Dexcom is still having the connectivity issue in 2019.
 
Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.
 
Terrible 
This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.

I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Please do the new version to work with iPhone 11 
Please do the new version please
 
No longer updated? 
While I realize many have upgraded to the G6, I quite enjoy my G5. However, the constant “functionality” messages I have with the updated iOS version plus the lack of complications for my recent upgrade to a series 5 Apple Watch makes me wonder if Dexcom is forcing the upgrade.
 
Great product, horrible support. 
I’ve been very happy with the product itself, but they company support has been horrible. They generally refuse to provide support by email and demand you call them on the phone, no matter how many times you specify a phone call is difficult for you. This company has zero concern For anyone with audible issues on a phone and flat out refuses to accommodate phone impaired people by email.
 
Annoyed 
Please fix the bugs that make you delete and reinstall the app. I need this for my daughter. It’s annoying that you have to delete and reinstall every 2days.
 
crashes 
The app has crashed 6 times in the past 2 weeks, it causes you to lose everything, and you have to repair the transmitter. All it says on the screen is the app has stopped working, delete the app and reinstall
 
App incompatible with IOS 13.3 
Update your app to keep up with operating system updates. This is a basic requirement of your service!
 
App not working with iOS 13.3 
Since updating my phone’s iOS version, the app no longer functions properly. It has slowed my phone down to a crawl (I know it is the Dexcom app because when I delete it my phone is fine). Also, the app makes me delete and re-download if I restart my phone. Do not download iOS 13.3! Hopefully they will make their app compatible soon.
 
App keeps crashing, no longer compatible with IOS 
I want to start by saying that for about the first year, I LOVED this app. It has made my life so much easier being able to glance at my phone or my Apple Watch and know exactly what my blood sugar is. However, since the latest iOS update, the app keeps crashing and forcing me to delete, redownload, and re pair my transmitter. If I’m lucky I get a day or two out of the app before it happens all over again. Sometimes this crash happens in the middle of the night causing me to miss extremely important alerts such as urgent low glucose levels. This isn’t just inconvenient, it’s dangerous for those relying on the app for important alerts such as this.
 
Frustrated 
This app not supported by iOS version 13.3. My husband can no longer track his blood glucose levels using this CGM with his phone. I feel like we had something that really worked and it got yanked away!
 
Crashing 
App keeps crashing! I’ve had to and reinstall at least 3 times this week. What is up???
 
Unhappy 
For the last several months I have had to delete my app at least every other day because it gives me an error saying it is no longer working. That is very inconvenient and annoying especially since I have to take my transmitter out of my sensor.
 
App Fails 
App used to work great, but in the last 2 months it has failed several times. Make sure you write down the serial number of your transmitter so you can have it when the app fails.
 
It works sometimes 
It works .. sometimes .. they did an update an now anytime my battery is low the whole app needs to be deleted redownloaded , then have to enter the transmitter info all back in which is really incovient when out
 
When are u fixing app for new version iOS?? 
When are you guys fixing dexcom g5 for new ios version???
 
Does not work with iPhone 11 
You must be kidding ... cmon Dexcom, get with it.
 
Crashes weekly! 
Keeps crashing. Having to uninstall and reinstall... Please fix! This is our life-line!
 
App is not working!!!! 
The app keeps notifying me that “the DExcom G5 app is no longer working, please delete the app and re download it” ive done this twice now and had to re connect the transmitter and it just happened again!! This is getting aggravating and getting in the way of my blood sugar control.
 
I’m a diabetic 
The app crashes and says The Dexcom Mobile app is no longer working delete it and reinstall worst app crashing I ever saw it’s happened 10 times in like 3 months
 
Is this app available for my G6 
I want to use this mobile app but it won’t work with my G6. The only app I find in the play store is for a simulator and DexCom follow. Is there a DexCom mobile app for the G6?
 
Was good....but to many errors! 
The app keeps “losing connection” then makes you delete and re-download.... would be fine if you didn’t have to recalibrate the sensor witch takes 2 hours...... 👎 they need to fix this and make it connect faster because 2 hours is NOT acceptable when a user can drop to a dangerous glucose level in less then 30 min..🤦🏻‍♂️ also you can NOT turn off all notifications.... it overrides your set volume setting and SCREAMS at you until its acknowledged.. Very embarrassing for the user and unprofessional... very disappointed in the last few updates, especially for how much you have to pay for the product.... I would NOT recommend until the issues are seriously addressed... is NOT safe or reliable.
 
Need to fix NOW 
As a type 1 diabetic, for 15+ years, I am reliant on try dexcom. Unfortunately the past two months have been problematic as the app continues to pop up with the idea that I must DELETE AND REDOWNLOAD the application. This is the fourth time, at least, that this has happened. When this happens it makes me use a brand new sensor EVERY time. I’m not sure what the app issue is. It seems to happen if my phone died periodically but had also happened in the middle of the day with normal phone life. I am only issued enough sensors per month and I use this in conjunction to my Omnipod. If it doesn’t shape up, It may cause me to pursue another system.
 
Bugs 
Works well but every few weeks it says the app isn’t functioning properly and I need to redownload. Very annoying. What’s good guys?
 
Known Issues, No Update 
Reached out to Dexcom about the G5 reading issues in November. They are aware that the app is no longer working properly since the latest iOS update, but have not updated it in over 7 months. If support was supposed to end (no official word on this yet), then they should have announced it via the app. Instead, they’ve abandoned their G5 customers.
 
Needs an update yesterday 
My app hadn’t been working for almost a month now since the latest iPhone update. I have not had my sensor on for that long and that’s not good. Please update the app so I can finally have my sensor back on and feeling better then I do now.
 
Dexcom G5 apple app 
The Dexcom G5 app is 7 months old. In first week of January my Apple phone was upgraded to iOS 13.3.1 and the Dexcom G5 app does not work on my phone. When called Dexcom Tech Support early last month was told the G5 is not compatible with that iPhone upgrade. When asked when Dexcom would update the app was told 3 to 6 months. Would not recommend Dexcom to any diabetics due to poor support.
 
Yehaaaaaa 
Works great and I love it can’t wait for the G6 I will miss you G5 thanks for the good times DEXCOM RULES
 
Lose transmission 
I love having this on my phone instead of carrying the monitor. I am reinstalling this app again since it keeps loosing connection and unable to transmit. I can turn on the monitor and it’s reading just fine. I have an IPhone 10x.
 
You are endangering lives. 
Why does this app still not support iOS 13? Why did the developers not warn diabetics before they made the irreversible decision to upgrade to the new iOS? People depend on this software to make crucial medical decisions every day. Why is it still not working? Fix it, Dexcom. Assign the budget. Hire new developers. Do what you need to do to fix this. This is literally your business and it is your responsibility.
 
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬 
Fix your bloody app!
 
App is TERRIBLE 
The app for the sensor is AWFUL. It and makes the functionality of the sensor almost impossible. It crashes multiple times a day and you have to delete and reinstall. Tech support is zero help and for the last 8 months they keep blaming the iPhone software update and saying they’re working on it. I was on a cruise with hardly any internet and my app crashed. For over 24 hours, I didn’t have access to my blood sugars because I couldn’t reinstall. The constant crashing puts you at risk! Currently about to ditch the Dexcom all together and go with another more reliable company.
 
Not great 
At night I like to use my receiver not my phone so I usually turn off my Dexcom app. But even when I swipe up this app to close it, it still runs in the background - so this app on my phone wakes me up if I’m low or high in the middle night. I have to delete this app and redownload it about every 2 days. Very frustrating.
 
Great when it works 
I just downloaded this app because my sons receiver messed up and our insurance want pay for another one. We decided to download the Dexcom app on his phone and the follow app on mine so I can watch what’s going on since this is new to us. Well his Dexcom app isn’t working and my follow app isn’t working either of course.
 
Always disconnects 
It says signal loss for periods of 30-90 minutes at least twice a day, regardless of actual signal strength or connection. Additionally, I don’t like how notifications are loud and can override the iPhone if you turn them off in settings.
 
Please FIX LANDSCAPE IMAGE! 
Your 3rd screen in the app above has been changed BADLY! When I turn my phone landscape and run my fingers across the values in the middle, IT COVERS UP THE TIME AND DATE-STAMP! My previous versions of Dexcom G5 app NEVER PERFORMED THIS WAY! I have been using the G5 since Jan, 2017!
 
Dropped connection 
At first I really liked this app and the switch to a phone/platform that supported the app was worth it; as it allowed me to carry one less controller and I was able to share information with my spouse as advertised. After a couple weeks of sharing my spouse no longer got information. The app tells me “no internet connection” and the Follow app on my spouse’s phone says “Dexcom server error”. It will not allow the current follower to be deleted or a new follower to be added. Now four weeks into using the Dexcom G5 mobile app it no longer gives me readings either! I have had to go back to using the old CGM. I am getting an error saying I am not connected to the internet when trying to log into the Dexcom G5 app. The first mention of this type of error I found was from 2017 on Google and Dexcom is still having the connectivity issue in 2019.
 
Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.
 
Terrible 
This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.
 
Frustrated user 
I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!

Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Please do the new version to work with iPhone 11 
Please do the new version please
 
No longer updated? 
While I realize many have upgraded to the G6, I quite enjoy my G5. However, the constant “functionality” messages I have with the updated iOS version plus the lack of complications for my recent upgrade to a series 5 Apple Watch makes me wonder if Dexcom is forcing the upgrade.
 
Great product, horrible support. 
I’ve been very happy with the product itself, but they company support has been horrible. They generally refuse to provide support by email and demand you call them on the phone, no matter how many times you specify a phone call is difficult for you. This company has zero concern For anyone with audible issues on a phone and flat out refuses to accommodate phone impaired people by email.
 
Annoyed 
Please fix the bugs that make you delete and reinstall the app. I need this for my daughter. It’s annoying that you have to delete and reinstall every 2days.
 
crashes 
The app has crashed 6 times in the past 2 weeks, it causes you to lose everything, and you have to repair the transmitter. All it says on the screen is the app has stopped working, delete the app and reinstall
 
App incompatible with IOS 13.3 
Update your app to keep up with operating system updates. This is a basic requirement of your service!
 
App not working with iOS 13.3 
Since updating my phone’s iOS version, the app no longer functions properly. It has slowed my phone down to a crawl (I know it is the Dexcom app because when I delete it my phone is fine). Also, the app makes me delete and re-download if I restart my phone. Do not download iOS 13.3! Hopefully they will make their app compatible soon.
 
App keeps crashing, no longer compatible with IOS 
I want to start by saying that for about the first year, I LOVED this app. It has made my life so much easier being able to glance at my phone or my Apple Watch and know exactly what my blood sugar is. However, since the latest iOS update, the app keeps crashing and forcing me to delete, redownload, and re pair my transmitter. If I’m lucky I get a day or two out of the app before it happens all over again. Sometimes this crash happens in the middle of the night causing me to miss extremely important alerts such as urgent low glucose levels. This isn’t just inconvenient, it’s dangerous for those relying on the app for important alerts such as this.
 
Frustrated 
This app not supported by iOS version 13.3. My husband can no longer track his blood glucose levels using this CGM with his phone. I feel like we had something that really worked and it got yanked away!
 
Crashing 
App keeps crashing! I’ve had to and reinstall at least 3 times this week. What is up???
 
Unhappy 
For the last several months I have had to delete my app at least every other day because it gives me an error saying it is no longer working. That is very inconvenient and annoying especially since I have to take my transmitter out of my sensor.
 
App Fails 
App used to work great, but in the last 2 months it has failed several times. Make sure you write down the serial number of your transmitter so you can have it when the app fails.
 
It works sometimes 
It works .. sometimes .. they did an update an now anytime my battery is low the whole app needs to be deleted redownloaded , then have to enter the transmitter info all back in which is really incovient when out
 
When are u fixing app for new version iOS?? 
When are you guys fixing dexcom g5 for new ios version???
 
Does not work with iPhone 11 
You must be kidding ... cmon Dexcom, get with it.
 
Crashes weekly! 
Keeps crashing. Having to uninstall and reinstall... Please fix! This is our life-line!
 
App is not working!!!! 
The app keeps notifying me that “the DExcom G5 app is no longer working, please delete the app and re download it” ive done this twice now and had to re connect the transmitter and it just happened again!! This is getting aggravating and getting in the way of my blood sugar control.
 
I’m a diabetic 
The app crashes and says The Dexcom Mobile app is no longer working delete it and reinstall worst app crashing I ever saw it’s happened 10 times in like 3 months
 
Is this app available for my G6 
I want to use this mobile app but it won’t work with my G6. The only app I find in the play store is for a simulator and DexCom follow. Is there a DexCom mobile app for the G6?
 
Was good....but to many errors! 
The app keeps “losing connection” then makes you delete and re-download.... would be fine if you didn’t have to recalibrate the sensor witch takes 2 hours...... 👎 they need to fix this and make it connect faster because 2 hours is NOT acceptable when a user can drop to a dangerous glucose level in less then 30 min..🤦🏻‍♂️ also you can NOT turn off all notifications.... it overrides your set volume setting and SCREAMS at you until its acknowledged.. Very embarrassing for the user and unprofessional... very disappointed in the last few updates, especially for how much you have to pay for the product.... I would NOT recommend until the issues are seriously addressed... is NOT safe or reliable.
 
Need to fix NOW 
As a type 1 diabetic, for 15+ years, I am reliant on try dexcom. Unfortunately the past two months have been problematic as the app continues to pop up with the idea that I must DELETE AND REDOWNLOAD the application. This is the fourth time, at least, that this has happened. When this happens it makes me use a brand new sensor EVERY time. I’m not sure what the app issue is. It seems to happen if my phone died periodically but had also happened in the middle of the day with normal phone life. I am only issued enough sensors per month and I use this in conjunction to my Omnipod. If it doesn’t shape up, It may cause me to pursue another system.
 
Bugs 
Works well but every few weeks it says the app isn’t functioning properly and I need to redownload. Very annoying. What’s good guys?
 
Known Issues, No Update 
Reached out to Dexcom about the G5 reading issues in November. They are aware that the app is no longer working properly since the latest iOS update, but have not updated it in over 7 months. If support was supposed to end (no official word on this yet), then they should have announced it via the app. Instead, they’ve abandoned their G5 customers.
 
Needs an update yesterday 
My app hadn’t been working for almost a month now since the latest iPhone update. I have not had my sensor on for that long and that’s not good. Please update the app so I can finally have my sensor back on and feeling better then I do now.
 
Dexcom G5 apple app 
The Dexcom G5 app is 7 months old. In first week of January my Apple phone was upgraded to iOS 13.3.1 and the Dexcom G5 app does not work on my phone. When called Dexcom Tech Support early last month was told the G5 is not compatible with that iPhone upgrade. When asked when Dexcom would update the app was told 3 to 6 months. Would not recommend Dexcom to any diabetics due to poor support.
 
Yehaaaaaa 
Works great and I love it can’t wait for the G6 I will miss you G5 thanks for the good times DEXCOM RULES
 
Lose transmission 
I love having this on my phone instead of carrying the monitor. I am reinstalling this app again since it keeps loosing connection and unable to transmit. I can turn on the monitor and it’s reading just fine. I have an IPhone 10x.
 
You are endangering lives. 
Why does this app still not support iOS 13? Why did the developers not warn diabetics before they made the irreversible decision to upgrade to the new iOS? People depend on this software to make crucial medical decisions every day. Why is it still not working? Fix it, Dexcom. Assign the budget. Hire new developers. Do what you need to do to fix this. This is literally your business and it is your responsibility.
 
🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬🤬 
Fix your bloody app!
 
App is TERRIBLE 
The app for the sensor is AWFUL. It and makes the functionality of the sensor almost impossible. It crashes multiple times a day and you have to delete and reinstall. Tech support is zero help and for the last 8 months they keep blaming the iPhone software update and saying they’re working on it. I was on a cruise with hardly any internet and my app crashed. For over 24 hours, I didn’t have access to my blood sugars because I couldn’t reinstall. The constant crashing puts you at risk! Currently about to ditch the Dexcom all together and go with another more reliable company.
 
Not great 
At night I like to use my receiver not my phone so I usually turn off my Dexcom app. But even when I swipe up this app to close it, it still runs in the background - so this app on my phone wakes me up if I’m low or high in the middle night. I have to delete this app and redownload it about every 2 days. Very frustrating.
 
Great when it works 
I just downloaded this app because my sons receiver messed up and our insurance want pay for another one. We decided to download the Dexcom app on his phone and the follow app on mine so I can watch what’s going on since this is new to us. Well his Dexcom app isn’t working and my follow app isn’t working either of course.
 
Always disconnects 
It says signal loss for periods of 30-90 minutes at least twice a day, regardless of actual signal strength or connection. Additionally, I don’t like how notifications are loud and can override the iPhone if you turn them off in settings.
 
Please FIX LANDSCAPE IMAGE! 
Your 3rd screen in the app above has been changed BADLY! When I turn my phone landscape and run my fingers across the values in the middle, IT COVERS UP THE TIME AND DATE-STAMP! My previous versions of Dexcom G5 app NEVER PERFORMED THIS WAY! I have been using the G5 since Jan, 2017!
 
Problem with the app telling me to delete it. 
The app is generally great but about once a week since September the app will make a loud beep and display a text bubble that states the app is no longer working properly and it needs to be deleted and reinstalled. Been doing this weekly for a few months now and it’s horrific. Hopefully the dev team is already working on a solution.
 
Dropped connection 
At first I really liked this app and the switch to a phone/platform that supported the app was worth it; as it allowed me to carry one less controller and I was able to share information with my spouse as advertised. After a couple weeks of sharing my spouse no longer got information. The app tells me “no internet connection” and the Follow app on my spouse’s phone says “Dexcom server error”. It will not allow the current follower to be deleted or a new follower to be added. Now four weeks into using the Dexcom G5 mobile app it no longer gives me readings either! I have had to go back to using the old CGM. I am getting an error saying I am not connected to the internet when trying to log into the Dexcom G5 app. The first mention of this type of error I found was from 2017 on Google and Dexcom is still having the connectivity issue in 2019.
 
Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.
 
Terrible 
This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.
 
Frustrated user 
I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!
 
No iPhone 11 update 
I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.

Problem with apple Xs max and Apple Watch 
I have a series 4 Apple Watch and I was using an iPhone 7 and everything work perfect now I have a new phone iPhone XS max and the only time my watch communicates and tells me my glucose level is when I am below 70 any other time I cannot use my watch to determine my glucose level
 
Email request for tech support gets return email stating it’s an unmonitored email address 
I think that about says it all. Calling them involved too long a wait time (x2), so I tried their email route using this app.
 
Needs work 
It is accurate most of the time, however it is not accurate enough that when you want to trust it it will not be accurate. You think this is working pretty good but the next time it will be way off big time.
 
needs maintenance immediately. 
i love dexcom, and i cant even count how many times it has saved me from lows. however, i DREAD having to replace my transmitters. every three months i needlessly struggle to pair a new transmitter. i follow every step to a T, yet i still have to delete and reinstall the app just to get the app to recognize that i have paired a new transmitter. i wait hours after hours for the sensor to warm up just to receive the annoying “???” when my phone has been no more than 5 feet from my transmitter and sensor the whole time. it should not be this stressful to make sure that my life saving technology is actually working, especially considering how much it costs. i don’t even think it needs to be said but there needs to be something done to fix this as soon as possible.

Signal loss 
This app would be great if it worked consistently. I am constantly losing signal and if I am. Not in the same area as my child I do not get any data. How am I suppose to monitor her blood sugar while she is at school. Id you fix the bugs this app would be wonderful.
 
Raj 
This app is the worst app I have ever used on my iPhone. I am actually surprised how it passed Apple’s QA team’s approval. The problem is it’s stability and annoyance factor. It constantly looses Bluetooth connectivity to the transmitter when no other device does, including Dexcom receiver. The alerts for things like loss of signal or a claim that “the app is closing” are embarrassing in public. I am forced to use this app to share my readings with my spouse who worries about my lows. If not I would not use it. I feel Dexcom needs to invest more on such apps. If they don’t react they might loose this app to someone else. There is so much of value that such apps can build. Maybe that is there ultimate strategy 😧to abandon this to someone else. I have been using Dexcom for a long time. Everything they do has always shined with superior customer satisfaction and product quality. This App is really a big bad blot for them. I hope they react to the low ratings that have for this app.
 
Sick and tired 
This app is horrible. Always disconnects. Can’t log in. Plz fix ASAP.
 
Constant Problems 
App needs a hot fix with this password BS that’s going around now (Aug 2019); and more options for sounds and volume. Sometimes at night I can barely hear it. I worry one of these nights I will pass due to not hearing an alarm. One reason I picked the app over the receiver is that I don’t have to carry an extra device around; now I wonder how the receiver performs compared to the Dexcom app. However it’s obvious that us diabetics have little to no choice when it comes to CGMs and their corresponding apps. Giving this app 2 stars bc without a CGM I would be toast. Please treat us with respect and fix the apps in a timely manner; it is life or death for a lot of us.
 
Solid, but some improvements needed 
I rely on this app a lot. It typically serves me well if I open the app on my phone. For some reason, the dexcom Apple Watch complication rarely works. It is constantly showing as blank. Only after I tap into it, and return to my watch face, it will then show my glucose number. That level of effort is about the same as opening the app on my phone. I’ve tried a workaround where I can get the readings on the face via the calendar app but even that has stopped working. Is there any way to get dexcom’s reading to consistently show on the watch??
 
Watch Face Support 
The Dexcom system is great, but I’d love to be able to take greater advantage of it by using more watch faces. Can there be better support for a wider range of Watch faces?
 
Great idea, poor functionality 
The G5 system has many great ideas but the simple fact that the app loses connection about 35% of the time makes this app simply not worth the trouble. I must carry my Dexcom Receiver with me all the time because I can’t rely on the app functioning properly. Overall I love Dexcom. The customer service since being sent to the Philippines has not been good, and the phone app is poor, but the overall concept of Dexcom products have been life saving for me.
 
Signal loss 
I have had several issues with Signal loss since updating to my new iPhone 11max pro , I called Dexcom several times about this issue they could not rectify the situation, they only suggested to send new sensors , they said that app has probably not been updated to support the new operating system on iOS , please help , only noticed problems developing after receiving new phone , Pattydziak @ Gmail.com
 
Question 
I love the app. I was just curious, what happens when my phone dies? You see this has happened plenty to me and it always disconnects. But last night my phone died sometime around 4am or so. But I have the data and readings. Can it still be taking/recording my BG even though my phones dead? That would be awesome. I don’t always have instant access to a charger lol
 
Not working after updating I phone to 6 S plus 13.1.3 
Updated phone and now it doesn’t see Bluetooth Please advise
 
App doesn’t see Bluetooth 
Bluetooth doesn’t work. Please fix this bug! I don’t receive blood glucose results 3 days!!!
 
Unsupported. No longer works since my phone auto updated to iOS 13 
Unsupported. No longer works since my phone auto updated to iOS 13. App is useless as it states BT is off, even though BT is enabled on my device
 
iOS 13 
I bought a new phone about a month and I haven’t been able to use Dexcom on my phone since then, it doesn’t recognize my transmitter even though I did accept the new Bluetooth settings when they showed up. This app used to work really well for me but now I’m really annoyed that I can’t use it on my phone anymore and I have a to carry around the receiver. I’m hoping you could fix the problem with iOS 13 so I could start using it on my phone again.
 
Need an update to the app 
Ever since the new update iOS 13 came out it continually will say that it cannons connect and it will try again in 30 minutes. It really needs a bug fix so we can continue on with our lives as normally as possible and not have to worry too much about our blood sugars.
 
Update needed for iPhone 11 
I rely on this app to provide reliable data, and the iPhone 11 is not compatible as of yet. When can this app be updated to work with the latest devices? Last update from Dexcom was more than 3 months ago, hopefully something new will be out soon?
 
DON’T UPDATE IOS!!! 
This app is incompatible with iOS 13. I normally don’t update for this reason but I must have pushed the wrong button because it updated while I was sleeping. Now it will not connect with my Bluetooth. Dexcom is aware and said they are working on it but don’t have a time frame for an update. My transmitter does not work and is out of warranty. Dexcom said there is nothing they can do so now I am basically without a cgm until this app is fixed. I know this is a vital piece of equipment for lots of people so I’m hoping this will help someone avoid my situation.
 
Doesn’t register 
I just went a whole day with no results. Very rarely during a typical dat does it receive results from my transmitter. Maybe 1/3 of the time. I just deleted it and installed a new one. Is it because my hearing aids are also Bluetoothed? Help, Tom Woodcock
 
Essentially Non-Functional 
UPDATE 10/29/19: New phone (iPhone 11Pro with iOS 13.x) and the app has a signal loss error more than it works. Called DexCom twice about it, and they have no explanation or solution. They say that the iPhone 11 isn’t supported, and neither is iOS 13. But the Apple App Store listing says iOS 10 or newer and doesn’t have any caveats about iPhone model. However, given that my DexCom receiver also has multiple signal loss errors each day, I believe that my transmitter is faulty. But Tech Support just looks at the date it was put into use and tells me that it couldn’t be the transmitter. So I guess I’ll just have to continue doing about a dozen finger sticks each day until they send me the next transmitter or, hopefully, the G6. The G5 has become more of a toy instead of a tool. UPDATE 9/30/19: It appears that the DexCom G5 Mobile app is not compatible with iOS 13!!! It gives a signal loss error multiple times every hour. Each time it tells me to wait 30 minutes to let the app regain signal capture. I called DexCom on this and they told me they didn’t know why the signal loss occurred, and implied that it was my fault in how I applied the sensor. These signal loss errors are happening even though my iPhone is less than 2 feet from the transmitter. Now, 12 hours later, it appears that my iPhone won’t link up with the G5 system at all. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress.
 
Will there ever be an update to this app? 
Would be nice to fix the warning about “this app hasn’t been tested on this iOS version” message. Especially on iPhone 11+, anytime you switch from the app screen this message is forced again when you switch back.
 
No longer works! 
No longer works! I haven’t been able to use my Dexcom for 2-3 weeks now. The app stopped connecting to Bluetooth. I bought another transmitter thinking that was the problem. Still won’t connect! It just gives me an error saying “transmitter not found”. So in the meantime, my insurance company and I are paying big bucks for something that doesn’t even work! Time to look for something else!!
 
Recent issues 
I’ve always had a great experience with this app but since the recent update on my iPhone I’ve had so much trouble. I’ve gotten multiple alerts that my app is no longer working to delete and re-download the app. This has happened several times in one day. I’ve been using dexcom for years and had less issues when the app came out in comparison to now. I’m wondering if it’s a push to get people using the G6 but it’s unfortunate and also life threatening. Hopefully you’ll figure this out.
 
Variable Results Recently 
Since the last iOS update last week, the sensor has been consistently much lower than the real glucose level for my gf (she has a G6) and I with the G5. We both have gotten urgent low warnings, while the glucose level was 300+ when testing. Something seems to be very off since that update.
 
I used to love dexcom 
I used to love my Dexcom, i told everyone that would listen about how great it is, but now i am being woken up 3 or more times a night and being told i am under 55, or a signal loss. Very frustrating. Now i am back to finger sticking 5 times a day cause i don’t trust any of the readings. I have even gone back to using the receiver and that still seems to sorta work if i am less than 2 feet from it. Dexcom needs to fix this soon or i am going have to look into another product.
 
Dexcom 
This unit is a joke!!! Poorly engineered.A pain to use and keep chasing it’s intended function .
 
Where is it going? 
Curious—the lovely circle with my current glucose reading seems to be exiting the phone screen to the right. Will it disappear, like the moon, and return on the left side? Apple iPhone 8, with current iOS updates. I took a screenshot today of the big orange sensor change circle—about 1/8 of it is gone on the right side. I also lose the 3rd digit of my glucose level. ? Help?
 
App unexpectedly not working 
I don’t know what’s going on but lately this app is unexpectedly not working properly and forcing me to delete and reinstall the app. I have assured it’s not my phone and this has happened a total of 5 times today. So at this time it is completely unreliable.😕🤦🏾‍♀️
 
Crashing 
The application is constantly crashing & prompts to “Uninstall Application / Reinstall. Please fix this issue. Thank You
 
Unstable & Unreliable 
On the whole this is a well designed app. I love Dexcom products, they are absolutely vital to managing my T1D. Recently, I keep getting an urgent message from this app to delete & reinstall. This has happened 3 times since the release of iOS 13.
 
Problem with the app telling me to delete it. 
The app is generally great but about once a week since September the app will make a loud beep and display a text bubble that states the app is no longer working properly and it needs to be deleted and reinstalled. Been doing this weekly for a few months now and it’s horrific. Hopefully the dev team is already working on a solution.
 
Dropped connection 
At first I really liked this app and the switch to a phone/platform that supported the app was worth it; as it allowed me to carry one less controller and I was able to share information with my spouse as advertised. After a couple weeks of sharing my spouse no longer got information. The app tells me “no internet connection” and the Follow app on my spouse’s phone says “Dexcom server error”. It will not allow the current follower to be deleted or a new follower to be added. Now four weeks into using the Dexcom G5 mobile app it no longer gives me readings either! I have had to go back to using the old CGM. I am getting an error saying I am not connected to the internet when trying to log into the Dexcom G5 app. The first mention of this type of error I found was from 2017 on Google and Dexcom is still having the connectivity issue in 2019.
 
Frustrated 
I love the concept of the Deccom. It’s a great tool in the fight for diabetes control. I would have given a 5 star but since Friday the app is down which means I cannot use my SugarMate app. They work so great together. Helps me to see if I’m going high or going low. With all the technology that is out there why is it taking so long to”fix”? When I try to log back in, I either get “you are off line”, which I’m not or I get the message “they r working on it”. This is so totally frustrating because I have come to depend on the Dexcom app. Please hire people who know what they r doing.
 
Terrible 
This used to be such a great asset but now it seems like the developers of this app either can’t or won’t keep up with the latest iPhone iOS updates. I can’t even use this app anymore because every time I try, it malfunctions, crashes, and I have to download it all over again only to have it crash and become 100% unusable seconds later. Stopped sending any info to my Apple Watch a few months ago right after the newest iOS came out. It’s not the phone cuz I just replaced the phone thinking something must be wrong with the Bluetooth... nope, it was the app. What a waste of time. Fix this, it’s inexcusable.
 
Frustrated user 
I’m constantly losing my signal on the G5 app. What is causing this? It’s very ignoring hearing all those notifications. I didn’t have this problem with the old release.
 
Dexcom 5 not working 
Wondering when the app is going to be fixed. I am unable to put reading in after finger stick. Been down for days and days!!!! Needs to be resolved!
 
No iPhone 11 update 
I guess I wrote the review below a month ago, but now I have to report that after a trip to the Apple store (because I had an iPhone out of service error message) the Dexcom app works perfectly. The store’s tech did an iOS reinstall and my apps reinstalled from iCloud. No problems since! After I got an iPhone 11, the app continually loses transmitter connection. The phone can be next to the transmitter and lose signal and it can be across the room and work fine. Might be an iOS issue which would be more disturbing since its last update was several months ago.
 
Doesn’t work with iPhone 11 
Why doesn’t the app work with an iPhone 11. I may switch sensors and transmitters to have a solution that works properly with my iPhone 11 Device. Keep getting notifications that the app don’t working properly and that it needs to be reinstalled. If I can’t get the data, I’m going to change my solution.
 
Useless 
How do you not keep up with mobile phone upgrades?!? It’s been three months since the iPhone 11 was released and I STILL can’t use this device. I’m going to have to switch to Medtronic. At least then I can use the very expensive medical device attached to my body. Fix your app.
 
Used 7 months - turned out to finally be garbage. 
I want ny G6 transmitter, please!!! - Dec. 19, 2019
 
Needs work 
12/2/19 Today app not working at all The app is freezing, no response to touch screen. Can’t get into app to ask for help. Believe you are having server problems, don’t know why it should affect my app The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5 This week keep getting messages that app is no longer working, delete and reinstall Called support and could not help because after hanging on phone 30 minutes the support staff just puts you on hold. Don’t buy not reliable and no support
 
Like Dexcom. 
I really am glad to have my G5. It has helped to drop my a1c and gives my wife peace of mind. She can pick up my phone during the night and know immediately my reading. Sister loves hers too.
 
Acknowledge from watch or locked screen 
This is a good product but it is annoying that you are unable to acknowledge high/low from iwatch or the locked screen. When I am in meetings is inconvenient that when I click okay on the iwatch it continues to double buzz until I go into the actual app on the phone
 
KN 
Had to download it at midnight two nights ago And now I get an error message telling me to delete and reload just before I sit down to dinner This is beginning to piss me off
 
This junk app crashes daily. Must be reinstalled. 
The Dexcom G5 worked great for the longest time but now that the G6 is on the market, this app crashes daily, requiring it to be uninstalled, reinstalled, & connected to Bluetooth again then resync the transmitter again. Same problem on iPhone 7, iPhone 8, & now the iPhone X. SUPER FRUSTRATING. Dexcom customer service is absolutely NO HELP.
 
Love and Hate with this app recently 
Of course the app is amazing, linked to my watch and the convenience while working and being able to glance at your wrist is freeing. I recently updated to the G5 and suddenly the app randomly will blast out a high pitch alert and then prompt me to delete the app and download again. This has been happening at least once a week. Time consuming and a pain! I saw that there is a G6 that came out and feel frustrated that I’m stuck with the outdated system and app. I’m ready to look into other options.
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Absolute trash of an app 
I was unable to get app to find transmitter. Go through all the trouble to get a replacement transmitter, now the app is telling me I don’t have internet connection to try again later. I HAVE INTERNET CONNECTION. Delete app and reinstall, not it is telling me it is incompatible with iOS version on my phone! I’m about to just have to kiss dexcom goodbye unfortunately. It’s useless at this point.
 
Account Password 
Just installing the App for the G5 on my iPhone and the field for the password won’t accept the PW I copied from my PW manager. It won’t accept a typed password either. Tried to reinstall but that didn’t work. Suggestions? Thanks in advance Bob
 
Problem with apple Xs max and Apple Watch 
I have a series 4 Apple Watch and I was using an iPhone 7 and everything work perfect now I have a new phone iPhone XS max and the only time my watch communicates and tells me my glucose level is when I am below 70 any other time I cannot use my watch to determine my glucose level
 
Email request for tech support gets return email stating it’s an unmonitored email address 
I think that about says it all. Calling them involved too long a wait time (x2), so I tried their email route using this app.
 
Needs work 
It is accurate most of the time, however it is not accurate enough that when you want to trust it it will not be accurate. You think this is working pretty good but the next time it will be way off big time.
 
needs maintenance immediately. 
i love dexcom, and i cant even count how many times it has saved me from lows. however, i DREAD having to replace my transmitters. every three months i needlessly struggle to pair a new transmitter. i follow every step to a T, yet i still have to delete and reinstall the app just to get the app to recognize that i have paired a new transmitter. i wait hours after hours for the sensor to warm up just to receive the annoying “???” when my phone has been no more than 5 feet from my transmitter and sensor the whole time. it should not be this stressful to make sure that my life saving technology is actually working, especially considering how much it costs. i don’t even think it needs to be said but there needs to be something done to fix this as soon as possible.

Signal loss 
This app would be great if it worked consistently. I am constantly losing signal and if I am. Not in the same area as my child I do not get any data. How am I suppose to monitor her blood sugar while she is at school. Id you fix the bugs this app would be wonderful.
 
Raj 
This app is the worst app I have ever used on my iPhone. I am actually surprised how it passed Apple’s QA team’s approval. The problem is it’s stability and annoyance factor. It constantly looses Bluetooth connectivity to the transmitter when no other device does, including Dexcom receiver. The alerts for things like loss of signal or a claim that “the app is closing” are embarrassing in public. I am forced to use this app to share my readings with my spouse who worries about my lows. If not I would not use it. I feel Dexcom needs to invest more on such apps. If they don’t react they might loose this app to someone else. There is so much of value that such apps can build. Maybe that is there ultimate strategy 😧to abandon this to someone else. I have been using Dexcom for a long time. Everything they do has always shined with superior customer satisfaction and product quality. This App is really a big bad blot for them. I hope they react to the low ratings that have for this app.
 
Sick and tired 
This app is horrible. Always disconnects. Can’t log in. Plz fix ASAP.
 
Constant Problems 
App needs a hot fix with this password BS that’s going around now (Aug 2019); and more options for sounds and volume. Sometimes at night I can barely hear it. I worry one of these nights I will pass due to not hearing an alarm. One reason I picked the app over the receiver is that I don’t have to carry an extra device around; now I wonder how the receiver performs compared to the Dexcom app. However it’s obvious that us diabetics have little to no choice when it comes to CGMs and their corresponding apps. Giving this app 2 stars bc without a CGM I would be toast. Please treat us with respect and fix the apps in a timely manner; it is life or death for a lot of us.
 
Solid, but some improvements needed 
I rely on this app a lot. It typically serves me well if I open the app on my phone. For some reason, the dexcom Apple Watch complication rarely works. It is constantly showing as blank. Only after I tap into it, and return to my watch face, it will then show my glucose number. That level of effort is about the same as opening the app on my phone. I’ve tried a workaround where I can get the readings on the face via the calendar app but even that has stopped working. Is there any way to get dexcom’s reading to consistently show on the watch??
 
Watch Face Support 
The Dexcom system is great, but I’d love to be able to take greater advantage of it by using more watch faces. Can there be better support for a wider range of Watch faces?
 
Great idea, poor functionality 
The G5 system has many great ideas but the simple fact that the app loses connection about 35% of the time makes this app simply not worth the trouble. I must carry my Dexcom Receiver with me all the time because I can’t rely on the app functioning properly. Overall I love Dexcom. The customer service since being sent to the Philippines has not been good, and the phone app is poor, but the overall concept of Dexcom products have been life saving for me.
 
Signal loss 
I have had several issues with Signal loss since updating to my new iPhone 11max pro , I called Dexcom several times about this issue they could not rectify the situation, they only suggested to send new sensors , they said that app has probably not been updated to support the new operating system on iOS , please help , only noticed problems developing after receiving new phone , Pattydziak @ Gmail.com
 
Question 
I love the app. I was just curious, what happens when my phone dies? You see this has happened plenty to me and it always disconnects. But last night my phone died sometime around 4am or so. But I have the data and readings. Can it still be taking/recording my BG even though my phones dead? That would be awesome. I don’t always have instant access to a charger lol
 
Not working after updating I phone to 6 S plus 13.1.3 
Updated phone and now it doesn’t see Bluetooth Please advise
 
Needs work 
The glucose reading is to the far right of my screen Can only see part of the reading. Numerous no readings even though phone is 2 feet from transmitter. Sensor failure are numerous rarely last 7 days. Maybe G6 System is better, I’m using G5
 
I’m giving it a 2 
I loved it before I got a new phone iPhone 11 pro and it’s not working it just freezes!!!! So frustrating I tried cohoe time to delete and app and download is again but it still freezes up. HELP?????
 
App doesn’t see Bluetooth 
Bluetooth doesn’t work. Please fix this bug! I don’t receive blood glucose results 3 days!!!
 
Unsupported. No longer works since my phone auto updated to iOS 13 
Unsupported. No longer works since my phone auto updated to iOS 13. App is useless as it states BT is off, even though BT is enabled on my device
 
iOS 13 
I bought a new phone about a month and I haven’t been able to use Dexcom on my phone since then, it doesn’t recognize my transmitter even though I did accept the new Bluetooth settings when they showed up. This app used to work really well for me but now I’m really annoyed that I can’t use it on my phone anymore and I have a to carry around the receiver. I’m hoping you could fix the problem with iOS 13 so I could start using it on my phone again.
 
Need an update to the app 
Ever since the new update iOS 13 came out it continually will say that it cannons connect and it will try again in 30 minutes. It really needs a bug fix so we can continue on with our lives as normally as possible and not have to worry too much about our blood sugars.
 
Update needed for iPhone 11 
I rely on this app to provide reliable data, and the iPhone 11 is not compatible as of yet. When can this app be updated to work with the latest devices? Last update from Dexcom was more than 3 months ago, hopefully something new will be out soon?
 
DON’T UPDATE IOS!!! 
This app is incompatible with iOS 13. I normally don’t update for this reason but I must have pushed the wrong button because it updated while I was sleeping. Now it will not connect with my Bluetooth. Dexcom is aware and said they are working on it but don’t have a time frame for an update. My transmitter does not work and is out of warranty. Dexcom said there is nothing they can do so now I am basically without a cgm until this app is fixed. I know this is a vital piece of equipment for lots of people so I’m hoping this will help someone avoid my situation.
 
Doesn’t register 
I just went a whole day with no results. Very rarely during a typical dat does it receive results from my transmitter. Maybe 1/3 of the time. I just deleted it and installed a new one. Is it because my hearing aids are also Bluetoothed? Help, Tom Woodcock
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Absolute trash of an app 
I was unable to get app to find transmitter. Go through all the trouble to get a replacement transmitter, now the app is telling me I don’t have internet connection to try again later. I HAVE INTERNET CONNECTION. Delete app and reinstall, not it is telling me it is incompatible with iOS version on my phone! I’m about to just have to kiss dexcom goodbye unfortunately. It’s useless at this point.
 
Account Password 
Just installing the App for the G5 on my iPhone and the field for the password won’t accept the PW I copied from my PW manager. It won’t accept a typed password either. Tried to reinstall but that didn’t work. Suggestions? Thanks in advance Bob
 
Problem with apple Xs max and Apple Watch 
I have a series 4 Apple Watch and I was using an iPhone 7 and everything work perfect now I have a new phone iPhone XS max and the only time my watch communicates and tells me my glucose level is when I am below 70 any other time I cannot use my watch to determine my glucose level
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Absolute trash of an app 
I was unable to get app to find transmitter. Go through all the trouble to get a replacement transmitter, now the app is telling me I don’t have internet connection to try again later. I HAVE INTERNET CONNECTION. Delete app and reinstall, not it is telling me it is incompatible with iOS version on my phone! I’m about to just have to kiss dexcom goodbye unfortunately. It’s useless at this point.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!!

Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?

Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.

Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.

New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.

Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse

Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered.

Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Love the app but you have to keep it open. 
I really like the app and how you can send your information to other people too, but my problem is that you have to keep the app open. If I close my phone it will say that the app is closed and that I will not receive information. This is a problem because my family member needs to see my blood sugar so they can check on me. If there is a way to solve this please reply. Thank you.
 
APP MUTES YOUR AUDIO YOU’RE LISTENING TO AGAIN 
please fix this, the old problem is back with latest update, whenever tapping on app to view glucose number, any audio you may be listening to is muted/paused. I only did the update by accident… I have learned never to update Dexcom apps because updates always make them worse
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.

Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
An alright application 
This app comes with a “share” feature which could have been useful if it had allowed sharing with the device the g5 came with. This app connects to the “health” app that comes with the iPhone... so does the app that comes with my meter and even the meter sent with the g5. Unfortunately, they chose to only send data to this app and not to retrieve data from it, so you still have to manually input the results of each test. App cherry picks which tests it uses for calibration, and only does so on its own meandering schedule. As a result, “calibration” tests appear to be ignored for the most part. I only get the expected behavior by entering the result twice in a row quickly. I certainly wouldn’t want something like this automatically making insulin adjustments, but it is very useful for having a very approximate read on how quickly my sugars are rising or falling over time. I am hopeful the g6 I’ve heard about will be more accurate and hopefully they’ll have improved the more basic functionality of the app for that model.
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍

My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?

I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…

Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.

Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.

Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Dexcom FAILS to keep app updated to support new IOS updates! 
Dexcom is slow on keeping medical devices compatible. This company is slow on supporting new devices.
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.
 
Rburns24 
I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Disappointed 
I just got my G6 GM...awesome! This app...major disappointment!. Set up my monitor, and at this time, who cares about saving the sensor small package?! I threw it away and this app is asking for thesensor (transmitter S/N (it won’t move past this window until S/N is typed. Well, okay, I did using my receiver info. Sensor S/N starts with an “8”, but app is saying it issupposed to start with a “4”. ???????????????????
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.

The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating.

While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…

Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.

Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…

Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently. Update 4/26/19: more crashes, more signal losses. Transmitter is just 1 week old. Sitting in my chair with my phone no more than 8 inches from the transmitter and the phone gives out a loud noise and says the app has closed. When I reopen it, it says signal loss. I can’t wait to get the G6 system. Hurry up and send it to me, DexCom!!
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead?

Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.

New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway.

It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.

Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.

If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.

Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍

I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.

New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.

Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.
 
Signal Loss 
I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.

I get signal loss for around 80% of the entire day, making having the Dexcom pretty much useless...
 
Dexcom 5 
I have this app on my I-phone 8 but it keeps disconnecting even when my phone is close to the sensor, and has not worked even for one hour. Please fix it, and add historical record capability so that I can check my average readings over a 90-day period
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
Where did 12-24 hour view go 
The new update removed a wider view of ranges. Right now, can only see a 1-3 hour trend of my mom’s glucose readings. The 12-24 hour was much more useful and critical to understanding her overall well-being. I looked everywhere to see if it was a “settings” issue but couldn’t find anything.

Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless.

The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Annoying notification 
“App is closed. You will not receive glucose information.” This notification going off every hour made me disable notifications for this app altogether. And there’s no way to disable this in the actual app.
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.

I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Dexcom transmitters talking directly with the Apple Watch 
Dexcom says the reason for this is Apple. Your response. Rodger
 
Not alerting 
What the heck is wrong with the update?!?!?!?! I used to get alerted all the time before the update! Not anymore! I woke up tonight to a reading of HIGH and NOT ONE ALERT!!! Why am I paying hundreds of dollars a month for this garbage?!?!?! FIX IT!!!
 
This app is garbage 
After using this app, and then using another, far better, app, and then being forced to go back to this app after the other app’s enterprise certificate was revoked, I can tell you how much I hate this app. Not to mention the fact that this app artificially shut down your transmitter after three months even though it may have 4 to 6 months more life left. The problems with this app are myriad. Number one it doesn’t allow you to turn off high and low alerts. It doesn’t give you control over so many things. The other app I was using had a notification on the outside of the app that told you exactly what your blood sugar was so you didn’t have to open it. This app forces you to open it. All in all I just cannot stand this app and can’t wait until the other app I was using is available through the App Store
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
Annoying notification 
“App is closed. You will not receive glucose information.” This notification going off every hour made me disable notifications for this app altogether. And there’s no way to disable this in the actual app.
 
Too bright at night 
Please invert the screen color for night viewing. The white is so bright I loathe looking when I wake in the night.
 
New IOS update 
I do know they are still testing on the new IOS update, but my Bluetooth connection has been TERRIBLE since the update, I keep my phone in my pocket and I’m getting signal loss’s every other hour, plus my readings take up to 15 to 20 minutes to update.
 
Not super functional 
The idea of a CGM that you can control with your phone is amazing, but it seems that if you use Dexcom on your phone, that’s what your phone is dedicated too. Rather than calls and entertainment, i worry about “My number isn’t going to show for the rest of the day if i watch this video” That’s another issue. The number barely shows, and if it does it’s hardly accurate. I’ve heard that the G6 does a better job at this, but insurance won’t allow me to upgrade. Also, the constant alerts about “Enter BG meter value” or “Your transmitter will stop working in three weeks,” and there isn’t any way to turn those alerts off. Another issue is the constant volume increases and decreases. Any alert i get lowers my volume, and then, with no consistency, will bring my volume all the way up, or won’t change after the app has changed my volume. It becomes frustrating, especially since i listen to music all day long to help with anxiety, then i’m blasted with a loud, obnoxious beeping sound that frightens me beyond belief. Finally, I don’t this to seem like there’s nothing good about the Dexcom CGM. There is, but as with everything, a new car, house, whatever, it has flaws. But these small flaws add up when you use this device on the daily. I like to compare it to working in an office. You want to be comfortable, because that is where you are going to spend the majority of your time. Dexcom is an office that has plastic school chairs, computers from the 90’s, and a cheap desk toy that your boss bought you and guilt tripped you into keeping. But some minor upgrades to that 90’s Compaq Presario could make it a better computer. An actual office chair, and getting rid of that stupid desk toy.
 
Rburns24 
I use G5 and when listening to music on my iPhone and get a high BS alert the volume of music increases to blast out of the room. Very irritating.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.

I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Constant signal loss with iPhone X 
Had it a week on my nephew he has the iPhone X and it’s a constant signal loss is there a fix in the future…
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season zero player yaaaaa
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍

There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Great app 
I’ve gotta say I get where some people are coming from with the volume problems and the lengthy update times but also you have to take into consideration that if the alerts didn’t change the volume enough and you missed them you could die and if the always updated the app at every needed moment that could be the moment where someone needs to know what they are and are in a bad situation where an update could cause a problem so while I understand where people come from they need to understand how many people rely on this to live, and that a couple inconveniences are something your just gonna have to deal with along the way.
 
This could be a top product but it’s like a beta version 
The graph on the watch does not give enough numbers range to be helpful. For instance the graph starts at 70 and goes up to 400 but there are no numbers in between give you an idea where your graph is in between.There should be a 100, 150, 200, 250,300, 350. For people who must not carry their iPhone with them all the time this is important. Because I must leave my phone behind when I go into a hazardous area I have no idea where I am with my blood sugars because my watch cannot communicate with my phone. However it does leave a trace of the graph where I am. If that graph had more numbers on it then this app would be Much more helpful. Look when I stepped away from my phone alI know is that I’m somewhere between 70 and 400. I then have to wait five minutes for my watch to reconnect to my phone. At that point in time I’ll step away again and less I end up going many hours without use of my Dexcom.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6. Update 3/9/19: just got a high glucose alert from the DexCom G5. When I checked the app, the BG shown was 130. Looking at the trend line, I haven’t been over the high glucose alert level since about 1:00 AM this morning, and I have been checking the app frequently today, since I have just had a medical procedure that is making my BG high and I’ve needed to adjust my insulin pump frequently.
 
Apple rx phone 
Is their a problem with the g5 app and the apple xr iPhone ? Can not get the app to function properly
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁

Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Wish list 
1. When in portrait mode, the app shows the past 4 hours. Please make the graph scrollable so we can scroll back to earlier hours at the same resolution. Be sure it always returns to current time whenever opened. 2. In landscape mode, put a buffer between the graph and the resolution buttons so the different resolutions can be more easily selected without invoking the individual values display. It would be great if these graphs could be scrollable, too! 3. When a high or low alarm has sounded, I wish it would desist once the direction is moving toward normal. e.g. the high alarm should sound when the reading reaches the threshold value, and should continue to sound while values are rising or holding steady, but should cease whenever values are falling, even if still above the threshold.
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.

Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Continued Loss of Connection 
This is becoming so frustrating to have the phone in your hand and the App says that it has lost signal!! I do love the technology, but please do something about this!!
 
Horrible loud beeps and no control 
Every person should have control over volume and being able to have a discrete device. This is the very opposite with this annoying new update. It was just fine before! I cannot have this intrusive and embarrassing beeps in meetings, when I’m putting a baby down for a nap, in libraries or in church. It’s anything BUT discrete. I will not use this until we consumers have easy volume choices or a vibrate only option.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
Volume control/BLARING alarms need to come back down 
Message to developers: please make volume go back to normal after Dexcom alarms blare? It seems that volume maxes out and doesn’t go back to normal when Spotify is running and playing music. It’s very problematic when working with your hands and can’t immediately turn it back down. Thanks.
 
Alarms don’t work half the time 
This used to be a good app but really 6 months since the last update. I was awaken last night with a low of 45 from the follow app on my wife’s phone. Nothing from mine. You folks do realize this is a life and death situation and your app failed! Get your crap together and fix this thing.
 
Doesn’t work with Apple Watch Series 4 
I am not able to see my Bg on the Apple Watch Series 4 watch faces
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.

Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever/smartwatch in class, I'm just annoyed by not being able to silence alarms. UPDATED: This problem has not been addressed. I have to turn my phone off during classes so I have no bg data during school hours to prevent disruptions in class. Please fix this!
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.

While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Good App, but needs improvement 
I love the low alerts. I’m still learning my patterns, so an alarm at 4 AM saves a me from disastrous crash. The alarms are why I chose Dexcom over a competitor. It would be useful to record the type of Insulin. I take two kinds. I can tell them apart by the numbers, but that may not always be case.
 
BEST APP FOR HEALTH 
If you have diabetes and take half your day on diabetes then download this app because it gives you so much free time to play outside or do sports and even play FORTNITE So ya it’s a very good app so download it if you have diabetes By the way my fortnite name is SpentSkate73419 for whoever what’s to play with me I’m a season two player soo yaaaaa
 
Why can’t you increase blood glucose font size? 
I liked the G5 phone app more because the the glucose number was larger. It becomes upsetting for any nearsighted user to struggle to see their glucose number. Half of the screen has a white background with this small number inside the circle.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Too Many Pairing Fails 
In the past, I had an issue with the app only here and there, but the past few months have been much worse. Every time I change my site, my app says I have a Pairing Fail. I try everything it tells me to, repeatedly, and eventually have to resort to deleting the app and even that doesn’t always work, so I have to carry my sensor with me anyway. I wish this app were more reliable.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
There is a new one 
The new Dexcom g6 doesn’t work for this but the share dose but u need to download the new app
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service

Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Useless on new Apple watch. 
Still waiting on an update for new watch complications.
 
Great potential but lousy app & customer service 
The concept is phenomenal — a way to test your blood sugar levels — without having to physically draw blood every few hours, but the execution is unreliable and frustrating. Here are the problems I've encountered. 1) Reliability. While Dexcom touts their latest iteration as being FDA approved for monitoring a patient’s blood sugar levels through the transmitter and the app, without having to verify those numbers, the system is rarely consistent. In fact, numerous times the Dexcom numbers have been twice as high or lower than the real figures derived from drawing blood with a pinprick and using a traditional meter to measure it. 2) I first tried Dexcom’s own Bluetooth meter, which often lost the transmitter signal and then took hours to start giving readings again. Things improved slightly when moving to their mobile app on my iPhone 7. But not that much. The app will squeal at the highest volume setting for hours if I am near being low. You can’t moderate the noise, or switch to vibrate, meaning that if you are at a public performance (the time you most need this technology) you can’t use it because if a blood sugar drop is sensed the unremitting screams from your phone will annoy all of your neighbors. There are other aspects which make the unit wonky (and I’m a former owner of a tech company), but I’ll spare you the post mortem analysis and lead you to the final problem: 3) Customer service is spotty, at best, and tech support non-existent. While Apple may update their OS every few months, Dexcom responds every six months to a year, and hence are always behind, leaving you with a glitchy piece of technology. I’ve tried a few times to see when updates would be issued and what they would include. No one at Dexcom knows or even has a guess when improvements or fixes will be published.
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Signal Loss 
My Dexcom app is constantly saying Signal Loss. I can’t find an update for this. Is there one? I have iPhone 7. iOS 12.1.2. Can you tell me how to solve this?
 
Dead? 
Is this app no longer being maintained? I haven’t seen any updates for it since the latest version of iOS was released several months ago... the current version works decently on iOS 11.4, but I’ve hesitated to update to iOS 12 because the app usually whines when I update my OS before an updated version of the app is released.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly

Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow.

Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).

Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
Great except for a couple things 
I love using dexcom because it helps take just that bit of stress away from diabetes management... Most of the time. There are several times, I'd say at least once a month, that something weird goes wrong such as signal lose for no reason or a weird message where it says that the cause is taking acetaminophen when I haven't taken any medicine recently. It would be nice to know why these happen for no reason this often. Also, I like the feature where you can set schedules for different alert settings at different times, but I'd love it more if you could set more than one time for a different setting. For example your normal has low, urgent low, and high alerts and right now you could set one called "school" to have the high alerts not alert during your school hours, but it would be nice if on top of that you could also set one called "sleep" where your high alerts make a louder sound or one that will more likely wake you up. Just a little suggestion. All in all, dexcom is a wonderful tool for diabetes management and the g5 app just has a few kinks that don't ruin the experience much. 👍
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.

My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Newbie 
Just started using this app with my iPhone and it’s way better than the Dexcom receiver. Also, used the CGM for the Medtronic pump years ago and like this way better. Can’t wait until I receive the G6. Hope the app is also an improvement. I’ll let you know in 2019. Technology makes living with T1D more bearable.
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Does not stay connected 
The app when it’s working is great, however seems to be disconnected far more than connected. If that could be fixed this would be greatly
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Has good potential but needs improvement 
Diabetes is the second cause of blindness, Second only two glaucoma. Accordingly, using the Dexcom apps with the built-in voiceover screen reader with an iPhone. Which begs the question, why is the Dexcom Ap not better designed for blind users using the built-in voiceover iPhone app? The apps are barely usable with voiceover, but needs labeling of buttons, alerts should automatically declare what they are and what the blood sugar level is currently running to deserve the alert; so that a diabetic can determine whether something needs to be done immediately or later on without having to resort to stopping to get the phone out and look to find out what is going on, as well as make the items most used available from the main screen of the app rather than having to go to other menus to find out what is needed. These are a few of many bugs which demand immediate attention. I love what this invention does and could potentially do for all diabetics whether visually impaired or not or use an Apple Watch. even a blind diabetic can use this app to maintain a constant blood sugar, but still could be improved so that average non-screen reader users can use the app in the dark without assistance. If the alerts spoke The low blood sugar levels automatically, that would cure many ills with the Dexcom apps in my experienced. These ideas should be easily and quickly implemented into the Dexcom app programming.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping

I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!

So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Better with Samsung 
I thought my Samsung was bad at signal being lost.... doesn’t even compare through Apple. About 70% of my day is “lost signal”!! My phone is next to me all day everyday there is no reason why signal is lost. Inadequate readings. Beeps at me for urgent low when my BS is in the 80s or 90s. I have to recalibrate multiple times a day between the misreadings and lost signal and it still isn’t enough. It barely works!! What’s the point of getting help when it doesn’t help!? This app is a joke for iPhone. I miss my Samsung.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem. Update #2: I am still waiting for fix for the Apple Watch series 4. Very seldom do I see anything but (- - -) on my Watch complication, where I expect to see my glucose level. I only get a reading when I touch the watch face. It also still doesn’t work on my Series 3 Watch either. Hope Dexcom is getting close to a fix. It’s a great product otherwise.
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Who’s writing this thing? 
With all the money Dexcom pulls in a year you’d think they could push updates faster. UI is garbage, still has no Apple Watch 4 update alongside no support for new faces and complications. Sugarmate is a free app that’s way more user friendly and in depth. Maybe you guys should hire that dev. Figure it out.
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!

Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!

Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Love Your APP 
With about 3 months under my belt, I am still new to Dexcom. I think the CGM and the APP are great. In fact, I have developed a dependency on my Dexcom Technology. I could not believe it but I was in range (70-150) 97% of the time 3 of the past 4 weeks. I am generally able to stay in the mid 90's and above because the Dex alerts allow for much more rapid response and correction. Also, Yesterday I mis-overestimated carbs (or fat) in dinner and was alerted to a low which dropped to 56. By the time I got there, I was feeling extremely shaky and had to alert the leader of my evening class that I would be late because I could not drive "as is." I missed less than 30 minutes of a 2.5 hr class! I did not get into playing the "high-low" game by over correcting because I forced myself to be uncomfortable taking small doses of orange juice and waiting to see if it was enough to correct the low. I just sat, drank water and watched my Dexcom chart! It took a full hour to correct the situation - but still, I made it to class and was able to alert the instructor in advance about why I was late. This is all just miraculous as far as I am concerned. Life changing! Am not quite to "no finger jabs" but looking forward to when Medicare okays the G6!!! Thank you Dexcom and APP development IT folks for a great product!!!!
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!

Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down.

I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁

After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁

The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.) Update: I was kindly contacted by Dexcom and was walked through a few steps to correct this issue (see above). They suggested rebooting the App, as well as rebooting the iPhone X. I did both, and unfortunately this did nothing to fix or even improve the situation. So please keep working on the Dexcom App to fix this pesky problem.
 
Good until it completely breaks 
I love the G5 app and it has given me so much freedom in treating my diabetes and one less device to carry but the way it breaks down every time there is an iOS update is ridiculous. My dexcom probably has signal loss 20-22 hours in a 24 hour day since the most recent update rendering it completely useless. Yes, I have a receiver but I don’t use it normally so the process to set it up and use that for the time being is incredibly frustrating and completely messes up my blood sugars. It’s disappointing that this has happened for multiple updates now.
 
Antiquated 
I’m new to the Dexcom g5. Although I love the whole sensor thing I’m pretty disappointed in the app. I would love to see a spot where I can add some personal notes for me and my doctors to review. Notes like which insulin I took or what I did for exercise or what I ate. Just a spot to add my own notes that could also be shared
 
Works ok but... 
Getting constant signal loss every few minutes. Don’t if it’s because I’m also hooked up with the Tandem X2 pump reading my numbers as well or if the app isn’t as stable.
 
Ios12 Bluetooth problems 
Please fix the app to work with the new version of apple I’m tired of having to reset the transmitter and reset the Bluetooth for it to work 2 hours and drop out again and show the black question mark .... so frustrating
 
Dexcom G5 app 
My phone updated to the newest IOS and I had been putting it off for months, the app doesn’t work well with the new IOS and I’m pretty much back to finger sticks all the time. I can’t afford to have that much of a difference in the numbers. Sad too because it has been giving my family piece of mind.
 
Rarely works 
Despite all the updates this is the most unreliable app I have ever used. I recently changed my transmitter and now it doesn’t work at all. The app either says sensor warm up or transmitter not found. I have uninstalled, reinstalled and I do have the right serial number entered. On the other hand I started using my dexcom receiver again and it works great as long as I keep it charged.
 
Dexcom G5 
This phone app works great but looses Bluetooth signal frequently even when my iPhone 6 is in my pocket 2’ away from my transmitter. I have deleted the app, very annoying
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.

I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.

And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
Transmitter died in one month. 
I don't know how this company gets away with the stuff they do. I have been on the Dexcom for years then out of the blue. They Say they have to do insurance verification and they delay my order buy one and a half months. Then I receive my order and the Transmitter battery goes dead In one month. I call,And they tell me it will take two days to replace. This is a medical device used for dosing decisions. The defective transmitter should have been replaced and shipped overnight air . How they get away with this is unknown. They seem to be scamming the system or should I say insurance companies and or Medicare. You see when they delay a order it's more profitable t them in my opinion. They most likely are billing the uinsurance for a product that has not been shipped. The standards have really gone down hill with Dexcom. You tell me to contact customer support that won't resolve anything. Customer support is useless they have very limited information. Its a workaround for you,it will not resolve any issues. I have contacted customer support it does nothing to resolve the issues. you are so happy to replace a sensor because they are so cheaply made and cost very little to manufacture. But when it comes to a transmitter that could possibly be defective there is no way you are going to replace that. Customer support always says,it cannot be the transmitter. They say this Because that's a big money item and you will not replace that unless the battery dies early. Dexcom has worked for Me in the past it is not just me being upset about one bad sensor. My body type is of normal height and weight . Something is defective either in your sensors or transmitter, you are outsourcing manufacturing without proper quality control. My BG was 76 from meter and it was stable the Dexcom told me it was 120 with two arrows straight up. You are going to end up killing someone eventually if you haven't already. I do still use the Dexcom I only wrote this review so people can't be aware of the problems that can occur. When it doesn't work it works well. Never rely completely on the Dexcom always double check with a fingerstick when making those some decisions. I have been AItype one for over 16 years so I am not new at this game.
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.

Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.)
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
Use to be Awesome 
Been using this for a few years now but with ios12 pretty much useless. Loses signal all the time. Never had this issue before ios12. Please correct this.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.

For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.)
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Great way to keep track 
It’s perfect for having blood sugars at your fingertips at all times without having to carry around another device. I always have my phone with me anyway so it’s great for me. I would add one feature: A note section. There’s a place for things like illness and stress. But there are many things that can affect blood sugar besides the few things they list.
 
Could be great 
The Dexcom system is amazing, and this app could be great, except it’s much too inconsistent. I often look to check my blood sugar and my phone has lost the signal with the transmitter. So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Rarely works 
My 9 year old daughter loves her dexcom but I’m just about fed up with it.... the app is my main complaint. 1) when we first got dexcom it worked great. The app was almost flawless. But despite keeping up with updates it slowly became less and less reliable. I was seeing the “no data” screen 50% of the time after a few months. 2) In September it was time to get a new transmitter and despite trying multiple different transmitters it is NEVER able to pair. Most recently it took about a dozen attempts and 3 days to get it paired and working. But after about a week we are back to constant “no data” screens. Yet it works fine on the receiver.... My daughters phone and my phone have not recorded a blood sugar reading in two weeks now. We have tried different sensors, different transmitters, deleting and reinstalling the app, updating the app, updating the phones, literally keeping the phone attached to her hip all day in an attempt to pick up a signal, assessed our internet/WiFi (everything is working), and we still can’t get this app to work. I really want to get rid of dexcom because I’m sick of paying hundreds of dollars (insurance only covers 50%) for a device that hardly ever gets used anymore (my daughter constantly forgets her receiver, but never forgets her phone... it would be GREAT if all she needed was her phone...). My daughter wants to give it another chance but I’m at my wits end. I’m not a tech savvy person and this frustration of constantly trouble shooting is driving me crazy!
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.

I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha

So I find myself having to carry around the receiver anyway, which sort of makes the app useless. It is particularly frustrating to wake up in the morning and see that I lost the signal most of the night. Not only is that dad lost, but it’s dangerous to not get alerts when I am low.
 
Incompatible with iPhone XR 
Does not work with iPhone XR at all
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.)
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Decent but mostly lost signal. 
I’ve had a G4 and now a G5 and have used the IOS app since it came out. I’ve used it with several iPhones and the updates have made it not very dependable. iPhone 6, 6 plus, and iPhone 8 - all show more time with “Lost Signal” than an actual number reading. My phone can communicate with other normal and low-power Bluetooth devices up to 30 feet away. But your transmitter loses signal with my Iphone when it’s a foot away. Technology has advanced and Dexcom you need to get better developers to get your app updated. Not all of us are ready to move up to the G6 for various reasons. Your software updates are months and months in between. Please get some decent folks working on this because it’s a very important safety decode for a lot of us, particularly when sleeping
 
A True Lifesaver 
I can't speak highly enough of this app! In over two years, I've never had any problems with the app. It functions perfectly round the clock, and allows me to control my Type 1 diabetes with great precision. Thank you, Dexcom!
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.

Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.)
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you

I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Pretty good but... 
I love that I can see the Dexcom sensor number on my Apple Watch, but I am disappointed that more times than not, the Dexcom complication on the Watch face has dashes (- - - ) instead of the numbers from my sensor. Only when I touch the watch face on the app complication will it then show the number I was looking for. If this could be fixed, I would be very happy. (Apple Watch series 3 and 4 both have this issue.)
 
Dexcom G5 mobile 
First finger stick entry not working!
 
Need to update for new series 4 Apple Watch 
Love Dexcom but the app needs to be updated in order to use complications on new Apple Watch series 4
 
A few things to make it better 
I would like to control all the alarms on the phone app, not good when you are in a meeting and the alarm sounds very loudly and you have no way to shut it off, even temporarily. Should be able to control it like the hand held receiver. I have to shut off and delete the app when in meetings so now I just don’t use it at all, and that’s not a good thing. Also you should update your App Store information as Medicare now let’s you use this app.
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.

It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.

Dexcom G5 mobile 
First finger stick entry not working!
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
Signal Lost 
Love the Dexcom!! Best thing ever for diabetics!! Recently I decided to connect it to my iPhone X, worked okay a awhile, but then I kept losing the signal .. last night I decided to change sensors, but the signal loss continued most of the night. I was very frustrated. This morning I went back to my old mobile receiver. For some reason my iPhone X is not receiving signal and continually goes off .. 🙁
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored. Update 10/9/18: got up this morning only to find that the app showed a signal loss from when I went to bed. It stayed that way for another 20 minutes. This was in addition to the several other signal loss alerts received over the past couple days. At no time was the phone more than 3 feet from my body. I sure hope DexCom upgrades me to a G6 in the near future - assuming Medicare will cover the G6.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!

Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Could use an update for new watches. 
New complications can't use dexcom so now I can't get this on my watch anymore?
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you

I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
Worked well at first but not anymore 
I’m super sad and disappointed because I relied on this app for so long but it will n I get pair to a transmitter anymore since the last update. Ha
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time

Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.

Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Fulfills its purpose, somewhat... 
Two things I don’t like about the app: 1. It doesn’t give you an alert sound when it’s time to calibrate. This would be helpful. I sometimes find myself going thirty minutes without not even knowing I needed to calibrate. I don’t think it’s caused any accuracy problems though. 2. It registers times wrong. For example, when I want to put in how many carbs I ate at time x, it puts a totally different time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!

Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
More range 
Please make the app reflect actual blood sugars. We do go above 399 sometimes. This is a time when we need the app the most. Also a further range from sensor to phone would be helpful.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.

No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate.

It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail.

Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.

Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Audio needs improvement 
It’s will raise and lower the volume of the device without warning. Sometimes it’ll raise the volume up to sound and alert, but then it won’t turn it back down. Also since I got my new phone, it says the app stopped working and to restart the app every 5-30 minutes. This is unacceptable. I can’t use this if I’m at work. I’m having to remove my sensor and go without a sensor, this is not good. Please fix this.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.The low alert alarm is defective if set at a specific number like 75 it will contritely go off when the number goes below 75. Lets say its at 65 it will go off every time the value goes up until i go over the 75 Threshold. So every 5 to 8 minutes i get a alam until i go over the set low i put in. I understand there Is supposed to be a set time for a repeat alarm. This option does not work it should .The only alert that should go off in this manner should be the urgent low. Also when your blood sugar gets below 39 and the Dexcom only says LOW with no number value ,good luck with the alarm even working it shuts of ..because there is no number value for a alert to go off. When 39 or lower the alarm should go off often when a Person is below 39 they are in serious hypoglycemia territory If they are not unconscious at 39 they will be shortly this is when a alarm should continuously sound. Warning the person they need to take immediate action There is no waiting around for a few minutes at this point,take action now. And the alarm should not stop sounding until the danger Zone threshold has been crossed like 60
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
danger glucose readings are not accurate 
this is not good you get FDA approval to make insulin treatment decisions most of the time Dexcom is in accurate tells me I am higher than I actually am people could make inaccurate decisions based on Dexcom readings, this is dangerous and potentially fatal.
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100.

I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
Danger readings are in accurate 
The readings are in accurate on occasion they May fall within 20% Sometimes but if you are relying on this for dosing decisions the readings could put you in serious danger. They are not accurate All the time.
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?

This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.

I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
Signal loss 
Im lucky if I get the signal more than an hour a day. Very annoying. I have no idea if I’m doing something wrong. The app is just bad.
 
Not a good app 
Primary issues: 1) the app will ask me multiple times to input my blood sugar. I input a reading, and 5 minutes later it asks for another reading. I put in another reading and 5 minutes later it does the same thing. I was out on a 2 day backpacking trip and I had to stop five times within 20 minutes to input a reading. FIX THIS. Its easier for me to just check my BG manually than to have to calibrate this thing multiple times a day. I’m wearing it right now, but am taking it off as I’m going on a climbing trip this weekend and am concerned it’s going to do the same thing. This thing costs way too much money to have THIS be an issue at this point in the game. 2) anytime I open the app anything playing in the background stops. This is stupid. The app should not affect background music (or podcasts) as it has nothing to do with those things. I’ve experienced more frustration while using the Dexcom system and app than I have with almost anything in my life. 2 stars because even though medical technology doesn’t need FDA testing and approval to be sold to the public (if it did, I just bet these things wouldn’t be an issue), it’s a cool idea.
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you

I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Dissatisfied 
I’ve had this app for a while and it’s been totally cool but just recently it won’t connect to any transmitters. I’ve changed transmitters three times and it’s too expensive to continue to try with new ones. Very disappointed that I have this equipment hooked to my arm but no way to read the information making it useless. :/
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital.

Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX

New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Good app. Could use some features 
The new alert settings are especially useful for distinguishing your overnight thresholds from your waking thresholds. A feature I’d like to see is the current reading as a notification badge on the app icon. For devs: similar to how an app like Air Matters gives the current AQI reading. Thanks for helping make diabetes a little easier.
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.

I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Loses signal all the time 
I would love to say this app rocks but it just doesn’t. It’s constantly losing connection even though I have my phone with me literally right next to the transmitter. I often have to restart my phone to get it to reconnect. It’s such a pain.
 
Freezes!! 
Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you

Great app when I first got it but, for the last four or five times I had to change the sensor, it freezes when it calls for two blood glucose readings after warmup. Not very happy because now I have to take my own readings 5 times a day. Not why I got this. Can I upgrade to g6? Maybe there won’t be a problem?
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. After working with tech support we discovered the transmitter was defective. The app is very helpful but would like to have more control over sound settings.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Will not pair 
I have tried several times to pair with my transmitter but it will not pair. I have tried all the trouble shooting suggestions and nothing works. I also tried on a different phone with the same results. Using an iPhone 7 and iPhone 8. I also called Dexcom tech support and they were not able to get it to pair.
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.

I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing!

I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Terrible Apple Watch 2 interface 
I’ve been using the G5 with my Apple Watch for over a year now. The two used to communicate wonderfully. Now I have to actually open the Dexcom app on my watch to view my BG numbers, and that’s if they even show up! This is unacceptable for this to happen Dexcom! I want to be able to look at my watch and see my numbers and trend like before. I don’t want to pull my data from my phone, I can’t when I’m on the nursing floor in a hospital. Please make my experience like it was before; make me love with your product again, as of right now, I’m thinking of switching!
 
Watch app!!! 
I have really enjoyed using this CGM system. It improves my quality of life. Currently waiting on the new G6 to be delivered, which is on back order so hopefully soon. The only thing I would change is Apple Watch app. I think it would be nice to be able to calibrate through the Apple Watch. Instead of pulling out my phone to do that. I work in an environment that frowns on my phone being out(theme park).
 
I like the app just not the bleeding ears 
I like the alerts because they can warn me before I get into trouble the problem I have I that I am listening to my music or movie and then at max volune "BEEP BEEP!" Other apps seem to figure out that you have headphones in and don't blow my ears out. Why does this app have to do that. Also, I know that the sensor is coming to its. End on the 7th day. I don't need 50 million alarms the ENTIRE DAY. I got it after the first one. If someone clears that yeah I am aware the sensor will end at 6:35 pm. That is it. Please update that because it is extremely unnecessary and annoying
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading.

Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM

It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Disappointed 
I purchased the Apple Watch series 3 for the sole purpose of using the Dexcom App. Sadly, it does not meet my expectations. I expected it would would work very similar to the iPhone app...it does not. A very expensive lesson learned. I wish I could like this app!!!
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each time when restarted, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most. 8/9/18 update: iOS 11.4.1, G5 mobile version 1.7.8. The crashing has mostly stopped. I get a banner message a few times each day saying that DexCom is working to ensure that the app is compatible with the latest iOS. So far, there has been a pretty good improvement, so I’ll wait to see how things progress. My complaint list now consists of these items (so far): - If my BG is low, but I have corrected it by getting some carbs, even if the trend is upward I get low BG alerts. It would be much better if the SW would recognize the up-trend and stop complaining. - If I insert a sensor at, say, 9:30 AM and then do the two meter BG check at 11:30, the DexCom wants another calibration check at 11:30 PM. I’m usually in bed by then, so I enter a meter reading earlier, usually 9:30 PM. Even with that, the system still wants the 11:30 calibration. Early calibration entries seem to be ignored.
 
Nothing but problems 
We have three T1Ds in the house. Two of them have nothing but problems with this app since upgrading their phones to an iPhone 8. The third has occasional glitches with his 7. It seems that it isn’t compatible with the 8. Extremely problematic since one is a young child. Signal lost or app closed MULTIPLE times a day. We have taken the app off and reloaded to no avail. Had a friend tell us that he no longer uses his Dexcom for this very reason. With three diabetics supplies are far too expensive for a product that doesn’t work.
 
Can’t control app from Apple Watch 
You can’t interact with the app from the Apple Watch. You can see the glucose number and arrow but you can’t silence an alarm. So if you get an alarm, you still have to use your phone to silence it. The watch app does not sound an alarm. The watch app should do two things. First and most importantly it should alarm when needed and secondly it should show you the glucose level and arrow. This app does 50% of those. Can’t the people at Dexcom do better than 50%?????
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.

Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡

I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each tome when restarted it, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most.
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
Good 
Is da best
 
The Worst App 
This is the worst app ever. I have more signal losses rather than a successful read. I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
Great system, crummy app. 
I love my Dexcom, it’s been life changing! The app however... well it feels like it was made by a 16 year old android developer and abandon years ago. On my iPhone 6 which is listed as compatible it’s been buggy for years. Problems include: Alerts sound more often than programmed; my high alert is set to sound at 180 every hour, it’s currently pestering me every 15 minutes. Separately, if your sugars are drifting a little bit up/down around a set point you will get a high alert every time the threshold is crossed, even if it’s every 5 minutes. You can’t simply acknowledge a calibration notification; sitting in a movie when it wants a calibration? Be prepared to kill the app to shut it up. And the alert sounds... hope you are a fan of early 90’s cell phone noises and cheesy sound effects; fire trucks, a baby crying, toy ray guns... oy! One of them even has tape hiss in it... and not in some ironic hipster way, it’s just a crappy recording. Please Dexcom, let us pick our own sounds! P.S. No, I’m not going to send you my contact info. The point of replying to reviews in iTunes is that the discussion takes place in a public forum.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.

I can use the receiver because my last one dies but figured that until my insurance covers it, this September, I can use the app. Well, it can’t read the sensor if I am under the covers, and as I mentioned before, I lose signal more than I get a reading. I had the Dexcom 7plus, the G4, the G5 and. Ow I am waiting to get the G6, and I have to admit, I can always depend on my receivers but NOT the app. Maybe they should hire new developers and go back to the drawing board.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each tome when restarted it, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most.
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...

During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each tome when restarted it, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most.
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.

Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each tome when restarted it, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most.
 
New to the mobile app 
I love my Dexcom, almost as much as I loved my last sensor, but I haven’t been thrilled with the mobile app as of yet. I can’t seem to see any history so I have no idea if patterns are arising and I was having big issues with the transmitter not communicating with my new phone, I traded in my beloved android for an iPhone just for this app and I have been regretting it big time. The communication problem seems to have cleared up, but only after disconnecting all other Bluetooth devices, it returns when I reconnect my car or a wireless speaker.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.

I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.

If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
FIX THE VOLUME 
I’m having a huge problem with this app that causes me to become infuriated every time an alarm goes off. Basically what happens is that when I get an alarm the volume increases to max but doesn’t go down to whatever I had it set causing to have anything and everything I’m listening to or watching blast my ears and cause pain The other problems are small like being able to mute urgent low and time changing of alarms to repeat A couple features that they could add that would just be for visual or audio purposes would be adding a dark mode so that at night we won’t blind ourselves and the ability to put our own alarm noises Incase it’s easier to hear or more responsive to that one audio clip or song The only thing I really want them to fix is the first problem before I lose my mind and find a new CGM Thank you
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats. 7/23/18 update: the app has crashed three tomes today. Each tome when restarted it, it said there was a signal loss. The last time, when I restarted it, the signal loss lasted for abot 15 minutes. In my opinion, the current version of the app, at least under iOS 11.4.1, is far too unstable to trust for BG management, especially overnight, when I need it most.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!

Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Dead without it 
Love my Dexcom app. I use it with my Apple Watch. Suggestions for improvement: longer haptic signals on both Eathan and phone. Option to acknowledge alert from watch. Ability to pair Dexcom to watch and phone.
 
I love it but… 
I love the Dexcom app❤️,but even when I am right next to my phone 📱 it says no signal.😕 Please fix this bug. Otherwise, great app!😊
 
Why bring back the never silence alarms?? 
What a way to kill an app! The previous version was great! Now even if the cgm is off and giving me a false low alarm I can’t silence it. The fact that it will blare in a meeting or a movie and can’t be silenced, or while waiting for a reading to catch up. Yet again, way to force a feature that isn’t needed on everyone. What if you made it an option to always sound????
 
Fantastic 
I really love my Dexcom App. I’m not so sure about all these negative reviews. Everything works great, alarms work, and I can adjust everything to my liking. I’m using the lastest iOS on iPhone X. Thanks Dexcom for being there for me.
 
Major improvement over finger stick testing 
I’ve had type 2 for about 15 years, this device and the continuous reports have given me control I’ve previously never had.
 
This app needs major work! 
So I love the idea of the glucose monitor and I’d never go back to being without one but this app/device needs work! The fact that it is FDA approved to make Bolus corrections with is astounding to me based on how frequently it is inaccurate. I’ve also talked to the tech department on multiple occasions about signal losses. I take screenshots of every signal loss situation I’m in that’s not a legitimate signal loss situation. For example I’ll have a signal loss when my phone is in my pocket so I take a screenshot of that. I’ve sent those screenshots in an email to the Dexcom tech department for them to examine. I’ve stopped recording every time my BG readings are more than 30 points different because it happens too much! I literally just tested my BG, twice to confirm accuracy, and it was 199 and my Dexcom was telling me 118. My A1c’s are typically lower than 6.7 and I try to maintain a tight level of control but it’s tough to do so when your Dexcom is that far off of your actual BG! And it’s not once a week that it happens to be more than 30 points off but daily! I use a g4 with my g5 phone app because of how frequently I get signal losses on my phone. The Dexcom tech person I spoke to approved my to have the g4 because of the problems with the phone app. I understand that the sensor is not going to be entirely accurate and is a guideline for keeping control but when you aren’t getting a signal and your readings are over 30 points off those are potentially life threatening problems. Maybe I’m the exception and not the rule with my issues but they are significant enough, and have been happening since I’ve had the sensor, for the company to do some serious analysis of their app/sensor tech to make it a more reliable system. Again, I’d never go back to being without a sensor, I started this disease by testing my urine and matching the color of it after 5 mins to the color on a box, but what Dexcom needs to do is some significant development of their product to improve its performance.
 
Seriously? Copy/paste of what is new in release from last one? 
Come on folks! What supervisor ever approved this release and why oh why would I want to apply the update with so little detail given. Give users a little credit for some level of intelligence to understand what exactly is included in “bug fix”. What bug? Might I expect I experienced the bug and would see a difference? How would I know? I’m a developer and that description is unacceptable. Best hope I have is to wait for more positive reviews which currently aren’t there. In fact as an iPhone 7 Plus user I’m very hesitant.
 
Great 
App works great! Love it!
 
Update 
I definitely think this app needs to keep up with the latest iOS updates!
 
Love my Dexcom but.... 
I love my Dexcom, it has literally been a life saver for me as a newly diagnosed type one diabetic. It allows me to maintain better control of my blood sugars and gives me a piece of mind. When I first started using the Dexcom G5 back in October I never had any issues with my alerts, but lately I have not been getting any sounds with my alerts. This is worrisome for me. When I am at work I often get so busy that I don’t have time to keep looking at Dexcom and don’t hear my phone vibrate with the alerts. I need the alerts to sound and I hope that with the update I just did it will do so again. I’ve taken to carrying the receiver again just because of this. I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
Not mutable 
Can’t mute the urgent low alarm, which can be disruptive especially since it repeats. It will still sound even if phone is muted and don’t disturb is on. Also can’t change the settings on urgent low. Generally works fine though its not uncommon for signal loss and errors to appear.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work. 7/20/18 update: iPhone 7 Plus, iOS 11.4.1. The app continually reports signal loss and then reports that the app has closed (and I won’t receive BG readings. The app can immediately be re-opened and will run properly for a couple of hours before the cycle repeats.
 
Issues with losing signal all the time 
Good functionality but I gave to re-pair with Bluetooth multiple times a day and I have to manually go in and fix the connection and regularly reinstall the app. Just about to upgrade to G6 but if that has the same problems I’ll be dumping Dexcom and trying something else as it’s too much of a pain
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?

I’m becoming more and more unaware of hypoglycemia and won’t start having symptoms until I’m in the low 60’s and sometimes even into the low 50’s. This could be dangerous not hearing an alert.
 
Medicare recipient 
If I read this update correctly, I cannot use it because I am a Medicare recipient. I use my cell phone, and iPhone 6s, all the time to get my numbers. Tell me if this is correct, or am I reading it wrong. I use the united healthcare AARP plan.
 
Will not connect. 
After the newest update, my transmitter will not connect to the app. I am getting very frustrated with this system. I need something reliable!
 
Annoying 
I’m really happy that I did NOT download the latest update. With so little detail given in the what’s new section I sensed that the only modification was that they must have figured out how to reactivate the annoying noise-maker. Seems I was right.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate. Update 7/18/18: I am finding that the app crashes at least once per day. My suspicion is that it has a memory leak causing the problem. Also, the app has frequent signal losses, regardless of the distance of my iPhone from the DexCom transmitter, which ranged from 4 inches to maybe 10 feet. iOS 11.4.1 did not solve any of these problems. Overall, the app needs work.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate.
 
Don't depend on this to work 
I am reinstalling this application for the second time. I started with dexcom four days ago. My iPhone 7 plus told me to replace the sensor 4 times in the last four days. Twice today. Customer service asks the same questions each time I call and they send a new sensor each time. I think they finally escalated it. I guess that's procedure don't think it's s problem till the customer calls 4 times. I was told it is not compatible with iOS 11.4. their application download says it does and it works until it tells me to replace my sensor.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.
 
Bich by Bhad Bhabie 
How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.

I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.

I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
Hate it! 
I love my Dexcom but not with the IPhone app. No matter what I have tried it will not connect with my Bluetooth and the sensor is forever getting disconnected. So not worth the hassle I’m going back to the other transmitter.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus. I am on iOS 11.4. No audible alerts, just vibrate.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone.

After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus.

Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
Life changing! 
I’m a huge fan of Dexcom. The app is good but could be better.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.
 
Bich by Bhad Bhabie 
How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).

Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
Loosing data after iOS 11.4 
I am loosing data after my iPhone had completed an authorized instructor update. Now loosing data sporadically. Spoke with Apple Store, they are unable to assist. Is there a bug? Will this be resolved soon?
 
Pls update app 
I just got my Dexcom this week, and I love it! The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
New to Dexcom 
I preferred to use my iPhone 8 with my Dexcom 5 so I wouldn’t have to carry more devices around but I’m finding that the app is causing start and stop problems with videos. They only way I can watch videos is if I shut down the app. Any fixes to this problem?
 
Notifications 
This latest update does not allow me to silence notifications. I tried closing the app as well as disallowing notifications in the iPhone settings and it still vibrates/rings. This does not work for diabetics in the workplace who at times need their alerts to be silenced.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.

The app, is amazing, woke me up when my bg was 60 at 3 am, my only complaints are- I try to send an invitation to my family for the Dexcom share app, but it won’t send them the email, they don’t receive it on iCloud, the only other thing is I keep getting notifications that the app doesn’t support the latest IOS update, so that would be nice as well, other than that I really like it!
 
Need New Update PRONTO 
I would like to update to the new IOS but I cannot because my Dexcom app here tells me that it won’t work if I update my iPhone. I’m glad it let me know that but so I’m waiting patiently for Dexcom to update their system and no luck. I shouldn’t be left out of something because a company cannot update their software that I NEED to use.
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update.

Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
If you have a phone older then the SE don’t download 
I have had it with this app I have to constantly call dexcom to fix a wide array of problem. This takes my time and patience and I’m about done , if it weren’t for my parents telling me not to I would smash the dexcom and delete the app. FIX YOURE CONSTANT ISSUSES, the amount of times I have sensor failure is unbelievable it makes me so mad.
 
Constantly Loses Connection 
The app is always losing connection with my sensor. At least 3 times a day. It’s even worse with the iPhone watch! What’s the point of having the watch if I still have to carry my phone in my pocket and not even be able to count on it?
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged.

I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
What’s wrong? Help please 
It keep saying sensor failed please delete app. WHAT DO I DO?
 
Have always loved the app 
It’s a lifesaver! I gave it three instead of five stars because of the latest ISO update. It hasn’t kept up with the update and it has bugs that relate to alarms going off. Nobody wants to miss their alarms. Can’t always keep your phone ringer on in every situation. And it keeps disconnecting too. I really hope they fix this soon. Want to hear my alarms not all my phone calls sometimes.
 
Low notifications 
I would like to be able to set a low notification at 110 or 120. I have twins who are 5 years old. Both T1D and it would be helpful to have an earlier warning so whoever is caring for them can start paying attention to their trend earlier than 100. If they are going down quickly it can take a bit to get back up after we go below 100.
 
Good but I have an idea 
I like it there is just one thing it needs. You should be able to choose if it is going to high alert in the day or night. Because when I am sleeping if I am high it alerts and makes me soooo mad! Please make update so my high alerts can only alerts in the day time.
 
The app is helpful, but alarms are useless at night 
During the day, it is easy to hear alarms. It is super helpful to have my phone make noise to alert me of a problem with my blood sugar. It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus.
 
Getting there 
The newest updates have been great to a degree. I do hate, (make toggles) that it lowers my music and sounds the nuke alarms when my sugar is low. I also hate opening the app and it telling me it’s compatible with my iOS version. Happens once a day. Yeah, I get it. I don’t need a reminder every day. These imposed intrusions are not ok. I’d like to have preferences that allow me to adjust things I don’t like. I may look for another app that works with Dexcom if I can because holy crap is this app intrusive.
 
Awesome 
It was life changing for me. I love it so much!
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.
 
Bich by Bhad Bhabie 
How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.

It makes day-to-day activities a lot easier not having to check my sugars every five minutes. However, I am a pretty deep sleeper. I feel the alarms should be able to wake me up in the middle of the night if I am super high or low. They need to be louder and more consistent. This could definitely be a feature that you could turn on for specific hours of the day so that you have normal alarms for most of the day and louder ones at night. I am finding a large issue with not waking up because I feel it is completely necessary to be woken up with bad blood sugar as opposed to waiting through the night and waking up with either Ketones or a shaky hand feeling like I may pass out (side effects of high and low sugar). Other than this issue, I think the app has really impacted my life as a person with diabetes and has made going about my day a lot easier. Thank you!
 
Alarm Override Dysfunction 
Found out the hard way that the ALARM override dysfunction DOES NOT WORK with the current version of iOS. All three alerts: fall rate, low, and urgent low FAILED to override the mute and do not disturb settings that are auto set on my phone during the night. This is the most important feature of the app for safety of someone sleeping alone to prevent potential death from hypoglycemia during sleep. I had a severe hypoglycemic event the night of June 5th and was not alerted during my sleep with the three alarms I’ve become accustomed to for my safety. I sleep alone. This resulted in the worst hypoglycemic induced seizure and closest near death experience of my life. I’m still recovering from this more than two weeks later. In retrospect the event occurred between 1-2 am from what I gather looking at the graph. I dropped below 40, the lowest readable number on the app. I woke up several hours later to my actual morning alarm still hypoglycemic and very beat up.
 
No Alerts? 
After Medicare OK’d the use if a smartphone with the G5 DexCom, I downloaded the app. But the app says my version of iOS won’t allow alerts. Gee, that’s great. Now that I’m allowed to use the phone, it doesn’t do it’s most important job? By the way, my iOS version is the latest, and I’m on an iPhone 7 Plus.
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded. Another improvement would be allow information to feed automatically from another app for carbs consumed, for example ‘My Fitness Pal’.
 
Much room to improve 
Things I like about this app: - the BG trend lines and ability to zoom in and out with regards to time - the schedule option that was recently added Things this app lacks: - ability to enter type of food consumed - ability to enter specific type of exercise done - ability to write more detailed notes for all events that can be entered There are also definite issues with volume control for alerts. I can’t easily change the volume for my specific alerts, and I can’t make the alerts more frequent (esp at night, when I would like a low alert repeated more than every 15 or 30 min...). I also don’t hear some alerts when my phone is charging, which I do all night.
 
Great! 
A great tool to mange your blood sugar but it should be easier to turn of the notifications! When u turn ur ringer off it still will beep as well as vibrate! It should only vibrate when ringer is off.
 
Awesome 
It was life changing for me. I love it so much!
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
It doesn’t work. 
I am running an iPhone 6 with the most recent OS. They don’t even have an app for my samsung G8 Active, which is a newer, popular phone. My phone will not stay connected to the transmitter, and I have changed transmitters and uninstalled reinstalled the app multiple times. The phone stays less than a foot from the transmitter. It connects for an hour then says no signal found. Bluetooth on the phone works great...stays connected to the car no problem
 
Not getting alarms 
Every time there is an update for iOS this app doesn’t work properly. I am no longer getting audible alarms when I have a low which is one of the main reasons I have the Dexcom/app. The app is saying to use the transmitter but I really don’t want to carry 3 things around all of the time. I have my phone, insulin pump equipment and now the transmitter too. The point of the app is to not have to carry the transmitter. Please get it updated! I am a nurse and I can’t have all of this stuff on my person all of the time.
 
Volume insanity 
Can you not control the volume of the alerts????!?!? It’s either ridiculously low or full blast. It scares me half to death and wakes my husband up at all hours. PLEASE FIX
 
“Signal Lost” 2 
Apple’s iOS has had 3 firmware updates in the last few months, while the dexcom app has none. Might be ready to give Medtronics a try.
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.
 
Dexcom G5 app... sigh... 
Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow.

I thought I miscounted but the problem persisted.

Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Brian 
The app loses signal to often to be of slot of use. I like being able to have it on my phone but it's a little annoying when I have to say the heck with it and use the meter instead.
 
Signal loss 
Go ahead and get used to it because you’ll see it all. The. Time. I have to turn Bluetooth off and back on 23 times, then turn the phone off and back on 11 times. Then I’ll maybe get a signal back. 😡
 
“Signal Lost” 
Both my iPhone 7 and Apple Watch Series 3 keep receiving the “signal lost” notifications frequently throughout the day. I usually close the app and relaunch. If the notifications come in every 5 minutes usually 3 or 4 in a row, I will need to turn Bluetooth off, then back on, then relaunch the app. If it keeps doing it, I will then power down the iPhone for a minute. Then power on and reconnect to the app. It’s been an ongoing thing for a few weeks. I have also replaced my Dexcom Transmitter within the last week to see if it was that. PLEASE UPDATE ASAP. This has been a huge annoyance in my life. On a lighter note, I would like to Thank You, Dexcom, for this piece of technology that’s helped me manage the T1D. It really means a lot to me, and the rest of the diabetes community.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
Does not respond to customer support emails! 
I’ve twice used their support emails and twice gotten no response. Call them instead you say? Well I did, but the agent did not know how to answer my question (regarding ordering supplies on the cusp of a new model being released). Plus, I want support answers in writing because I’ve been lied to before about the cost of diabetic supplies (what’s up Tandem!) and then held accountable for a cost I was unprepared for. This is terrible customer support in general, but when you deal in medical device supplies which are used every day to keep patients alive, this is especially garbage “support” for your consumers. I’m ready to try products from companies that genuinely care about their patients.
 
Unable to pair new transmitter 
This is the third time I’ve had this problem with 3 different transmitters! It will not take a picture of the barcode and it just eats up the 30 min when I manually enter the code then it tells me I’m screwed! So frustrating 😫
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.
 
Dexcom G5 app... sigh... 
Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded. Another improvement would be allow information to feed automatically from another app for carbs consumed, for example ‘My Fitness Pal’.
 
Much room to improve 
Things I like about this app: - the BG trend lines and ability to zoom in and out with regards to time - the schedule option that was recently added Things this app lacks: - ability to enter type of food consumed - ability to enter specific type of exercise done - ability to write more detailed notes for all events that can be entered There are also definite issues with volume control for alerts. I can’t easily change the volume for my specific alerts, and I can’t make the alerts more frequent (esp at night, when I would like a low alert repeated more than every 15 or 30 min...). I also don’t hear some alerts when my phone is charging, which I do all night.
 
Great! 
A great tool to mange your blood sugar but it should be easier to turn of the notifications! When u turn ur ringer off it still will beep as well as vibrate! It should only vibrate when ringer is off.
 
Awesome 
It was life changing for me. I love it so much!
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.

Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier

New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Sound 
The new updated app is great. I have a major problem though... I can’t get any sound! I have uninstalled and I have restarted my phone! Help I need sound vibration does not always catch my attention!!
 
alert fatigue 
the notifications for this app are beyond annoying! many can’t be disabled or customized, and they can’t be silenced from a smart watch. this means you have to go all the way into the app every single time you get a notification, no matter how severe or trivial it may be. can’t calibrate for 30 minutes because you’re driving? get ready to receive 10-15 notifications that you need to calibrate. or, did you just calibrate with a reading outside your range? get ready for another alert a few minutes after telling you what you already knew. experiencing a frequent signal loss? same deal. this becomes especially irritating when used in tandem with the dexcom receiver, which is slightly more intelligent about its alerts.
 
Disappointed 
This is a very disappointing app. Works maybe half the time. Waste of money. I had a better A1C before the CGM
 
Best CGM 
Love Dexcom, love this app!
 
Update crashes 
I’ve been using this app for a while and all has been fine until I updated my iPhone. I haven’t been able to open the app since; it force closes every time I try to open it. I have to go find my old meter now :/
 
Low alert 
Unable to set the low alert to repeat at 5 minutes. I scroll to the 5 minute indicator and when pick my finger up off the screen it rolls back to the 0 minutes reminder. When I try to select 10 minutes, it rolls over to 15 minutes. As I’m sure you are well aware, if I am experiencing a low, I need to know as soon as possible, not in 15 minutes. Sometimes the first alarm doesn’t wake a sleeping person.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
Does not respond to customer support emails! 
I’ve twice used their support emails and twice gotten no response. Call them instead you say? Well I did, but the agent did not know how to answer my question (regarding ordering supplies on the cusp of a new model being released). Plus, I want support answers in writing because I’ve been lied to before about the cost of diabetic supplies (what’s up Tandem!) and then held accountable for a cost I was unprepared for. This is terrible customer support in general, but when you deal in medical device supplies which are used every day to keep patients alive, this is especially garbage “support” for your consumers. I’m ready to try products from companies that genuinely care about their patients.
 
Unable to pair new transmitter 
This is the third time I’ve had this problem with 3 different transmitters! It will not take a picture of the barcode and it just eats up the 30 min when I manually enter the code then it tells me I’m screwed! So frustrating 😫
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.
 
Dexcom G5 app... sigh... 
Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded. Another improvement would be allow information to feed automatically from another app for carbs consumed, for example ‘My Fitness Pal’.
 
Much room to improve 
Things I like about this app: - the BG trend lines and ability to zoom in and out with regards to time - the schedule option that was recently added Things this app lacks: - ability to enter type of food consumed - ability to enter specific type of exercise done - ability to write more detailed notes for all events that can be entered There are also definite issues with volume control for alerts. I can’t easily change the volume for my specific alerts, and I can’t make the alerts more frequent (esp at night, when I would like a low alert repeated more than every 15 or 30 min...). I also don’t hear some alerts when my phone is charging, which I do all night.
 
Great! 
A great tool to mange your blood sugar but it should be easier to turn of the notifications! When u turn ur ringer off it still will beep as well as vibrate! It should only vibrate when ringer is off.
 
Awesome 
It was life changing for me. I love it so much!
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.
 
Bich by Bhad Bhabie 
How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.

The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.

I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!
 
Works with IOS 11.4 - why can’t Dexcom say this? 
Apple released new IOS’s seemingly constantly. Yet there is no resource to know if it is safe for me to update for fear that the Dexcom app will brick after I update. To be clear, I love the app. I just want to know if the app works with new updates. Since there is no way to roll back updates and this is a medical device it’s kinda important. Would be easy to do, just try it for us and let us know if it works. Update: I bit the bullet and updated and it works. Yay! Why can’t Dexcom save us some stress and tell us if it works with all new IOS updates?
 
The best! 
Love my G5 cgm, thank you so much for everything. Anyone looking at this should know that this device will improve your numbers and keep you in better health.
 
Very inconsistent 
I have only been on this device for less than a month, but in that month I have experienced many inconsistencies! Many way more than their 20/20 Rule?, which by the way no explained to me during my teach session. Called tech support, they were inadequate at best. First two weeks I wore it was pretty accurate, but now with the changes it’s gone bonkers, way off form my meter. I am talking sometimes over 100 in differences. I am still poking myself the same amount of times, because I do not trust the phone’s numbers, so my question is what is the point of my insurance company paying for both??????!!!!!! Camtaf
 
Keeps crashing 
I love this app and the Dexcom but since some of the recent updates, the app crashes and I have to reinstall frequently. It’s annoying and frustrating. Please fix!
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of it alarming. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Best CGM 
Love Dexcom, love this app!
 
Update crashes 
I’ve been using this app for a while and all has been fine until I updated my iPhone. I haven’t been able to open the app since; it force closes every time I try to open it. I have to go find my old meter now :/
 
Low alert 
Unable to set the low alert to repeat at 5 minutes. I scroll to the 5 minute indicator and when pick my finger up off the screen it rolls back to the 0 minutes reminder. When I try to select 10 minutes, it rolls over to 15 minutes. As I’m sure you are well aware, if I am experiencing a low, I need to know as soon as possible, not in 15 minutes. Sometimes the first alarm doesn’t wake a sleeping person.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
Does not respond to customer support emails! 
I’ve twice used their support emails and twice gotten no response. Call them instead you say? Well I did, but the agent did not know how to answer my question (regarding ordering supplies on the cusp of a new model being released). Plus, I want support answers in writing because I’ve been lied to before about the cost of diabetic supplies (what’s up Tandem!) and then held accountable for a cost I was unprepared for. This is terrible customer support in general, but when you deal in medical device supplies which are used every day to keep patients alive, this is especially garbage “support” for your consumers. I’m ready to try products from companies that genuinely care about their patients.
 
Unable to pair new transmitter 
This is the third time I’ve had this problem with 3 different transmitters! It will not take a picture of the barcode and it just eats up the 30 min when I manually enter the code then it tells me I’m screwed! So frustrating 😫
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.
 
Dexcom G5 app... sigh... 
Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded. Another improvement would be allow information to feed automatically from another app for carbs consumed, for example ‘My Fitness Pal’.
 
Much room to improve 
Things I like about this app: - the BG trend lines and ability to zoom in and out with regards to time - the schedule option that was recently added Things this app lacks: - ability to enter type of food consumed - ability to enter specific type of exercise done - ability to write more detailed notes for all events that can be entered There are also definite issues with volume control for alerts. I can’t easily change the volume for my specific alerts, and I can’t make the alerts more frequent (esp at night, when I would like a low alert repeated more than every 15 or 30 min...). I also don’t hear some alerts when my phone is charging, which I do all night.
 
Great! 
A great tool to mange your blood sugar but it should be easier to turn of the notifications! When u turn ur ringer off it still will beep as well as vibrate! It should only vibrate when ringer is off.
 
Awesome 
It was life changing for me. I love it so much!
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.
 
Bich by Bhad Bhabie 
How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
Life savior 
I really like this app and dexcom. There are some bugs regarding the alert sounds but everything is great about this app.
 
can not change the settings 
before the update, I used mmol/L as the unit of my glucose. now it's mg/dL, and I cannot find where to change the settings...
 
Very sad about the quality of this app (and I realize iOS updates are part of the problem). 
First let me say that in spite of my complaint below, this app and your technology have saved my bacon more times than not. We need more of you and better QA in general from you (and Apple). iPhone 7 Plus, iOS 11.3.1. I realize on reading many reviews that some problems are design-choice specific issues. My issue is no matter how I configure the alerts, all the active ones signal as vibrate-only when I select a audible sound. I recently had to go to the ER and get stitches in my lip from a low signaled when I was sleeping - thankfully I woke up and got a sugar dose before I bottomed out, regardless I cut my lip against a table during a brief convulsion. Why? Because there were no audible alerts when I was sleeping as I had previously, even though the app was configured to give them. EDIT: Specifically, with the ringer switch on the left side in the silent position and the app alerts set to always sound I get vibrate-only alerts, even for the urgent lows. I realize now through testing that the only way I can get audible alerts is to never use the Apple ringer-silent option, which I believe is contradictory to your instructions. It would be great for you to add the sound testing capability you gave in the receiver to this app, as it means I can verify the config I have set is working as expected for each alert. I realize part of this is Apple’s problem as I frequently auto-update iOS during the night. The challenge I see now is the inconsistency of audible alerts not working even after an app update. Given I work in the tech space as a cpu designer I understand the multiple variables involved in getting an app to work properly, especially since there is no OS suitability guarantee for medical app use. For me the challenge is on older versions of this app the functionality worked fine, and then silently stopped working. Since I can’t reliably track or predict when this happens, this makes using a phone-based app a risky proposition when your life depends on a certain predictable expectation. I have no idea how you reliably solve this without Apple’s explicit support, since they release buggy iOS updates all the time. Rant off. A feature request similar to that of other reviews: it would be good to have an option to demote audible alerts to vibrate-only for a short period, say 10-15 minutes at most, and possibly have an option to renew the choice once. This would allow the user to ack that they see the state of their readings and are willing to take the risk of a non-audible alert, with the assumption they have taken appropriate action to address their current sugar trends. This makes this app more suitable for a business environment.
 
Nice but still have issues with this app. 
I like this app, but it still has issues with “signal loss” ALL THE TIME! If my iPhone is not literally laying on my tummy at night, I get a signal loss. If my iPhone is in my pocket in the daytime (where I usually keep it), I get a signal loss. I have good WiFi at home and at work so this should not be an issue. I wish you could fix this “bug”!

The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Problematic 
Ever since the new app/ update I’m having the same issues as others . Bluetooth , (brings the music really low and then volume suddenly rises ) Also reading never match when I calibrate . Never had these issues before .

Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded. Another improvement would be allow information to feed automatically from another app for carbs consumed, for example ‘My Fitness Pal’.
 
Much room to improve 
Things I like about this app: - the BG trend lines and ability to zoom in and out with regards to time - the schedule option that was recently added Things this app lacks: - ability to enter type of food consumed - ability to enter specific type of exercise done - ability to write more detailed notes for all events that can be entered There are also definite issues with volume control for alerts. I can’t easily change the volume for my specific alerts, and I can’t make the alerts more frequent (esp at night, when I would like a low alert repeated more than every 15 or 30 min...). I also don’t hear some alerts when my phone is charging, which I do all night.
 
App Loses Signal 
I love being able to check my glucose levels on my phone except the app is constantly losing signal every day. I’ve tried deleting and reinstalling almost daily and it doesn’t fix the problem. Should fix the app glitches before the G6 comes out
 
Great! 
A great tool to mange your blood sugar but it should be easier to turn of the notifications! When u turn ur ringer off it still will beep as well as vibrate! It should only vibrate when ringer is off.
 
Awesome 
It was life changing for me. I love it so much!
 
User Activity Modes? 
The schedule is a great start, but time of day is not very applicable for me. Can you develop something that is not time based, but activity based that I can choose when doing something? Allow a user defined name like “Long Run” and let us set some parameters for that. Increase the low levels and possibly tie that to fall rates. Voice dictation as an option to sounds. Would love to hear, “your sugar is now falling at your max threshold and is currently at 150”. Thanks! Keep up the great work!
 
Help get through a lot 👍😀😀😀😀 
Slept asherd I was okay 👌 😴😴😴😀😀😀😀
 
Why Dexcom is an amazing app 
Dexcom has helped me and my family control my blood sugar, especially at night. The fact that it gives an update of a person’s blood sugar is stupendous. I cannot praise the app enough for how much it has helped me, my family, and other type one diabetics across the world. #T1Dnation
 
DEX rules 
All you naysayers need to use the app to keep your BS in check. Your A1c will improve if you take it to heart. Don’t wimp out and think that it will not take dedication. Remember to change your lifestyle and don’t medicate due to your lack of control of your eating and lifestyle. It is easy when used correctly:)
 
A truly life-changing app 
Yeah, it isn’t perfect, and may occasionally act a bit flaky, but so what? I bought an Apple Watch so I could hopefully just twist my arm and see my blood sugar level. This does that, and like the phone app, does so in context. LOVE the up or down arrows that let you know if that 150 is rising (bad), or dropping (good). The ability to customize your alerts is fantastic. Want to cut off high highs at the knees? Set a lower high alert, and give yourself shots when the app tells you they’re needed. Honestly, the ability to feed the app data to my watch makes diabetes management SO unobtrusive. For that matter, the hardware in and on your stomach is pretty easy to forget too. As far as I’m concerned, the whole Dexcom team — from device manufacturers to app developers are heroes. They have helped me control my A1C, and have likely added years to my life. Healthier years at the very least. What more could you possibly want from an app? If I could keep only one non-Apple app on my iPhone, this would be the one. I can’t rate it highly enough.
 
The share link always has a 1 on it. 
Is there anyway to make the one disappear?
 
Can’t update 
I depend on this app but it is always difficult to update. I have version 1.7.6. A new version 1.7.7 is available and I don’t have the option to update. It just says “open” and it’s still the previous version. Happened with the last update too. All of a sudden one day I was able to update but after the release. I also understand the need to test the app on new versions of iOS but it can’t keep up. My phone is several updates behind. By the time dexcom approves compatibility with an iOS version, a newer version has come out and there’s no option to download an earlier version of iOS which would actually be a newer version for my phone.
 
"Alarm" design is just bad 
The way the alarm is implemented is useless when I'm sleeping which is when I most need for it to work. It just beeps a couple of times and then nothing. That isn't enough to wake me up from a sleep which is what is needed. It can't be that difficult to have it go off like a normal alarm that doesn't stop sounding until it is acknowledged. Maybe some people don't want that in which case it could be a switchable option, but what I need is to actually be woken up so I don't die in my sleep!
 
Better than it used to be! 
The app finally switches between noise and silence with the silent button on the phone. 🙌 Works fine, love having it as an app on my watch.
 
Makes life so much easier 
Being able to see my blood sugar on my phone and Apple Watch is just so convenient. It is great to cut down the devices I have to carry from 4 to 3. While the app could certainly be better I much prefer it to using a entire other device.

How can it access your volume and turn it up on its own even when your phone is on silent? 🔺🔺🔺🔺🔺
 
New update not working 
Hi. Love my G5 but since I updated the app yesterday I have had signal loss on my phone. I still see by BG on my pump but not in the app.
 
LOVE IT!!! 
I love the Dexcom app!!! It is so helpful with controlling my type 1 diabetes!!! This and the share app have both saved my life more than once!!! 💕🙌
 
Expensive Device - Cheap App 
I love my Dexcom G5, but the app leaves much to be desired. To get all of the features you’d expect, use the Sugarmate App WITH this Dexcom App and you’ll have a fantastic system for monitoring your BGL linked to your food, exercise, and medication.
 
Some features to add... 
I love having my Dexcom G5 on my phone. I’m glad Dexcom added the alert schedule feature. I would recommend that they also add a Dexcom Share schedule feature so you can control when you are sharing and when you aren’t. I have my mom monitor my blood sugar at night so I can sleep and I would love to be able to have that automatically happen every night instead of having to go into the app and turning share on. Another suggestion; I would like to have more alert tones to choose form. Ideally, I would be able to use the tones Apple provides so that when an alert goes off, it is more discreet. One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Problematic 
Ever since the new app/ update I’m having the same issues as others . Bluetooth , (brings the music really low and then volume suddenly rises ) Also reading never match when I calibrate . Never had these issues before .
 
Keeps crashing 
I love this app and the Dexcom but since some of the recent updates, the app crashes and I have to reinstall frequently. It’s annoying and frustrating. Please fix!
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of it alarming. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Best CGM 
Love Dexcom, love this app!
 
Update crashes 
I’ve been using this app for a while and all has been fine until I updated my iPhone. I haven’t been able to open the app since; it force closes every time I try to open it. I have to go find my old meter now :/
 
Low alert 
Unable to set the low alert to repeat at 5 minutes. I scroll to the 5 minute indicator and when pick my finger up off the screen it rolls back to the 0 minutes reminder. When I try to select 10 minutes, it rolls over to 15 minutes. As I’m sure you are well aware, if I am experiencing a low, I need to know as soon as possible, not in 15 minutes. Sometimes the first alarm doesn’t wake a sleeping person.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
Does not respond to customer support emails! 
I’ve twice used their support emails and twice gotten no response. Call them instead you say? Well I did, but the agent did not know how to answer my question (regarding ordering supplies on the cusp of a new model being released). Plus, I want support answers in writing because I’ve been lied to before about the cost of diabetic supplies (what’s up Tandem!) and then held accountable for a cost I was unprepared for. This is terrible customer support in general, but when you deal in medical device supplies which are used every day to keep patients alive, this is especially garbage “support” for your consumers. I’m ready to try products from companies that genuinely care about their patients.
 
Unable to pair new transmitter 
This is the third time I’ve had this problem with 3 different transmitters! It will not take a picture of the barcode and it just eats up the 30 min when I manually enter the code then it tells me I’m screwed! So frustrating 😫
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.

One more tiny thing that has nothing to do with the app; please stop saying in Dexcom commercials that Dexcom is for type two diabetics over 65. I’m thirteen and type one and I get embarrassed every time those commercials come on. Overall, this is a great app and it has changed many peoples lives! Keep being awesome!
 
Bluetooth Issues with 1.7.7 
I have had Bluetooth issues (Signal Loss) with the previous version of the Dexcom app. To get around that, I merely rebooted my iPhone each night. With the 1.7.7 update, my smart watch (Garmin Vivoactive 3) is now having issues with Bluetooth. The battery of the watch should last days to a week, and it dies in a day. My watchface (which happens to show my Dexcom data) is having difficulty staying connected (I get connection issues all day long). I have data that’s not current and a watch that dies too fast, and this all started 2 days ago when I updated my Dexcom app. I wish it was possible to revert. Now, my watch is almost useless to me.
 
Can’t silence 
I need to be able to silence. If I can’t, then I need to turn my phone off!!! This is a terrible upgrade! Please fix-so I can silence and still check my blood sugar.
 
Signal loss 
Ever since the update, I keep getting a signal loss alert for no apparent reason & when I go to the app it’ll just pop back up and all of my numbers will suddenly appear. Or sometimes it won’t come back for over a hour.
 
Apple Watch Sync 
I love this app, but I wish you had the ability to dismiss the alerts via your Apple Watch versus having to open the app on your phone and dismiss them every time.
 
Crashing issues 
You have done a good job improveing this app. But ever since the latest update, the app seems to crash at random. It's ok for a few hours then suddenly it stops. I am unaware why this is happening, but I would like to request you try to fix it. It's difficult to monitor my blood sugar without it crashing every hour. Please look into this. Thanks!
 
Update has problems- PLEASE roll back to previous version 
Lately many lost signals and 3 question marks and way high blood sugar false positives. This is all since update. Never was like this before. It makes the thousands of dollars I’m spending feel like a waste
 
Good update but alert problem 
So I love the scheduled alerts and things but there’s needs to be an option where there’s no sound or vibration alert. And in place the phone would just light up. This would be a great option for meetings or activities where silence is necessary.
 
Rarely Updates Apple Watch 
I have been using Dexcom for many years and have spent thousands on their products. I am obviously a huge fan, and having a CGM make managing my Type 1 easier. Unfortunately the Dexcom app on my watch rarely has my BG reading...just the frustrating three dashes. I have to touch the app on the watch to get it to update with my phone. And yes, the phone and the watch are in close proximity to each other. Dexcom, please fix this. I should be able to glance at my watch and see my BG via the Dexcom complication on the watch face. Having three dashes is not helpful. I might as well pull out my phone if your Apple Watch app is always oblivious.
 
Mobile app truly not CGM 
Mobile app disconnects hours at a time even after following the advice given by customer service. I recommend calling into Dexcom if you have similar issues!
 
Great system, mediocre app 
I have been using the Dexcom for several years and have never been completely happy with the app. It has certainly improved, but there are still a number of issues that require workarounds on my part—creating way more time and attention than before I had a CGM and defeating the purpose of simplifying the life of a person with diabetes. Alerts: Alerts are not customizable enough. The “always sound” functionality would be better suited by alarm, rather than time frame. I would also like an option to change how frequently each alarm sounds if I haven’t responded to it (an unresponsive low overnight would obviously require more frequent alerts than a high during an afternoon meeting if I’ve left my phone at my desk, annoying my coworkers, for example). Alerts are also very annoying to get rid of. If I have a high blood sugar and it’s rising, I have to open the app and dismiss two alerts—but the details of my blood sugar are shown on the app. Most apps dismiss alerts once you’ve opened the app in response to them. Since the alerts are telling me the same thing the app interface does immediately upon opening it, I should not have to dismiss each alert manually. Update notification: This notification shows up without any consistency and is incredibly obnoxious. I will often open the app to update my blood sugar calibration, click on the calibration option, and then the notification will appear. This causes me to have to restart the app, because the notification “accept” button is hidden behind the box that pops up to type in the blood sugar—which can’t be used, because the system requires me to accept the notification first. Installing a small exclamation point on the main dashboard which you can click to see any pertinent notifications, rather than having to accept this notification every two or three times I open the app, would greatly improve my experience. Transmitter expiration: The app will notify me when my transmitter is about to expire, but once I dismiss this notification there’s no way to check the date of expiration until the next time the app gives me this notification. Range: Please expand the high glucose range to 500, since most glucose monitors can check that high. The system is clearly reading it (I still get the arrows telling me the direction of my blood sugar).
 
Great until the recent update 
I am a huge DEXCOM fan. But this recent app update has been a disaster. I love the alarm scheduling option. That’s been a huge improvement. But, I’ve had nonstop issues with the Share option. My boyfriend helps track my bg on the DEXCOM Follow app and hasn’t been able to see my data since the upgrade. Nothing we’ve tried seems to work. This is a huge disappointment as one of the attractions to DEXCOM is it’s compatibility with iOS. As a an active Type 1, it’s helpful knowing I have an extra set of eyes on bgs - especially from someone who knows exactly what intervention to take when I’m too high or low. I’m hoping DEXCOM fixes this issue soon, as it’d be nice to have that assistance again.
 
Issues with transmitter/support 
Normally this app works brilliant, but today we tried to start a new sensor and it quit the transmitter. After a panic, we found the number, put it in again, tried to start the sensor and it happened all over again. Then, trying to press the support button in App Store to let them know about the issue but it doesn’t work and we go nowhere. So, I’m writing this review. Please resolve these bugs.
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Problematic 
Ever since the new app/ update I’m having the same issues as others . Bluetooth , (brings the music really low and then volume suddenly rises ) Also reading never match when I calibrate . Never had these issues before .
 
Keeps crashing 
I love this app and the Dexcom but since some of the recent updates, the app crashes and I have to reinstall frequently. It’s annoying and frustrating. Please fix!
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of it alarming. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Best CGM 
Love Dexcom, love this app!
 
Update crashes 
I’ve been using this app for a while and all has been fine until I updated my iPhone. I haven’t been able to open the app since; it force closes every time I try to open it. I have to go find my old meter now :/
 
Low alert 
Unable to set the low alert to repeat at 5 minutes. I scroll to the 5 minute indicator and when pick my finger up off the screen it rolls back to the 0 minutes reminder. When I try to select 10 minutes, it rolls over to 15 minutes. As I’m sure you are well aware, if I am experiencing a low, I need to know as soon as possible, not in 15 minutes. Sometimes the first alarm doesn’t wake a sleeping person.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
Does not respond to customer support emails! 
I’ve twice used their support emails and twice gotten no response. Call them instead you say? Well I did, but the agent did not know how to answer my question (regarding ordering supplies on the cusp of a new model being released). Plus, I want support answers in writing because I’ve been lied to before about the cost of diabetic supplies (what’s up Tandem!) and then held accountable for a cost I was unprepared for. This is terrible customer support in general, but when you deal in medical device supplies which are used every day to keep patients alive, this is especially garbage “support” for your consumers. I’m ready to try products from companies that genuinely care about their patients.
 
Unable to pair new transmitter 
This is the third time I’ve had this problem with 3 different transmitters! It will not take a picture of the barcode and it just eats up the 30 min when I manually enter the code then it tells me I’m screwed! So frustrating 😫
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.
 
Dexcom G5 app... sigh... 
Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded. Another improvement would be allow information to feed automatically from another app for carbs consumed, for example ‘My Fitness Pal’.
 
Much room to improve 
Things I like about this app: - the BG trend lines and ability to zoom in and out with regards to time - the schedule option that was recently added Things this app lacks: - ability to enter type of food consumed - ability to enter specific type of exercise done - ability to write more detailed notes for all events that can be entered There are also definite issues with volume control for alerts. I can’t easily change the volume for my specific alerts, and I can’t make the alerts more frequent (esp at night, when I would like a low alert repeated more than every 15 or 30 min...). I also don’t hear some alerts when my phone is charging, which I do all night.
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse.

You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Problematic 
Ever since the new app/ update I’m having the same issues as others . Bluetooth , (brings the music really low and then volume suddenly rises ) Also reading never match when I calibrate . Never had these issues before .
 
Keeps crashing 
I love this app and the Dexcom but since some of the recent updates, the app crashes and I have to reinstall frequently. It’s annoying and frustrating. Please fix!
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of it alarming. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded.
 
Best CGM 
Love Dexcom, love this app!
 
Update crashes 
I’ve been using this app for a while and all has been fine until I updated my iPhone. I haven’t been able to open the app since; it force closes every time I try to open it. I have to go find my old meter now :/
 
Low alert 
Unable to set the low alert to repeat at 5 minutes. I scroll to the 5 minute indicator and when pick my finger up off the screen it rolls back to the 0 minutes reminder. When I try to select 10 minutes, it rolls over to 15 minutes. As I’m sure you are well aware, if I am experiencing a low, I need to know as soon as possible, not in 15 minutes. Sometimes the first alarm doesn’t wake a sleeping person.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
Does not respond to customer support emails! 
I’ve twice used their support emails and twice gotten no response. Call them instead you say? Well I did, but the agent did not know how to answer my question (regarding ordering supplies on the cusp of a new model being released). Plus, I want support answers in writing because I’ve been lied to before about the cost of diabetic supplies (what’s up Tandem!) and then held accountable for a cost I was unprepared for. This is terrible customer support in general, but when you deal in medical device supplies which are used every day to keep patients alive, this is especially garbage “support” for your consumers. I’m ready to try products from companies that genuinely care about their patients.
 
Unable to pair new transmitter 
This is the third time I’ve had this problem with 3 different transmitters! It will not take a picture of the barcode and it just eats up the 30 min when I manually enter the code then it tells me I’m screwed! So frustrating 😫
 
Such an awful app, so much potential 
Imagine a blood glucose tracking app where you can’t even add notes and comments about food, specific activities, sleep, etc. this app works well with the CGM system but does not allow you to add info about these important issues. They have a very primitive way of adding “carbs” but not about the food you eat. No way of coordinating with data from other apps such as Apple Health, My Fitness Pal, etc. So much potential, so little actuality. Last time I wrote a review I got the typical “contact us so we can make the app better” pitch. I did that, gave feedback, and no improvements. All talk, no action.
 
Bluetooth and Apple watch connection problems 
I really love this app and it is so convenient to be able to check my phone to see what my glucose is however, I can never get it to show on my Apple watch. One of the main reasons I got an Apple watch is so that I could easily look and see what my glucose is without pulling out my phone. I think it may be a Bluetooth connection issue because when I go to the settings on my phone, there is never a connection to my Apple watch. I've tried everything I can think of to fix this but with no success. At this point I'm assuming it's an app issue that is causing there to be no connection between my phone and Apple watch. By the way, I have an iPhone X and a first generation Apple watch.
 
Dexcom G5 app... sigh... 
Wanted to use the app as it’s great to have the information at your fingertips. Have the meter and receiver and transmitter, but instead of scrambling to find one with the readings, it’s great to have it available on the iPhone or my Apple Watch. If it isn’t constantly losing signal or connection... OR, more infuriating, having ZERO control over the alerts and notifications. Sound turned off on phone AND notifications turned off, the phone still alerts at the top level of high volume when blood sugars are too low or high. There ness to be more control as I sit in meetings and lectures and conference calls and need my phone on to receive texts and emails and be on the call while this alert infuriated me because it just won’t stop going off every few minutes. It does a great job, but you need to finely tune the control the user has with this app as it is loud and annoying when you’ve already dealt with your blood sugars but keeps notifying you with no volume or alert control when you e basically set everything to silent and no further alerts other than shutting the phone off in situation where you’re in public. It’s great if you want your neighbor to check on you if you’ve gone into hypoglycemic coma in the middle of the night and you’ve left your setting set on silent... Jeeeeeezusss.... Insane, please design or develop more control for the user. I don’t want to smash a 1,000$ phone because it won’t stop. But I’m close to doing it. Vibrate / volume control / different modes maybe? Holy ____... 👎
 
Dexcom is great, app falls short 
I upgraded to the G5 mobile at the beginning of the year. Having grown accustomed to the vibrating alerts on my G4 receiver 2=high, 3= low and 4 = hyperlow. The first time my G5 mobile vibrated twice I figured my sugar was high (no biggie I keep my parameters tight) when I looked at my phone it was actually low. I thought I miscounted but the problem persisted. After long conversations with tech support it was decided the app does NOT give the same vibrate warnings as an actual receiver (I can only speak as an iPhone user). The twin vibrate is currently (and in the foreseeable future) the only vibrate option. If you’re used to a receiver and want to ditch it for the app use caution. I will need to purchase a G5 receiver because I rely on the vibrate alerts.
 
Not perfect. But keeps me informed. 
The app is fine. The music thing was annoying. Especially because I thought it was a problem with my phone. Now I just keep getting alerts every five minutes if I’ve acknowledged the issue. It is starting to get annoying hearing the low glucose alert every five minutes. Especially when my phone is on silent for a reason.
 
Love the G5 and the app but.... 
Overall, I love my Dexcom device after suffering with Medtronic’s CGM for years. The app overall is pretty clean of bugs and dependable, albeit a bit simple. REQUEST: please consider changing alerts so they don’t go off within a short time frame of dipping below and above a threshold!! I.e. if my high threshold is 170, the app will alert me when it hits 170, then dips slightly, then comes back up to 171...over and over. The app should be smart enough to know the BG number isn’t really moving...no need to re-alert. Similarly, if I just typed in a BG o calibrate...no need to tell me its high. I just typed it in. I know. Thanks!
 
Issues 
Today i was doing something and my thing has not been working all day basically I am super confused on why it is not working!
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.

Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines.

And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.

Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Problematic 
Ever since the new app/ update I’m having the same issues as others . Bluetooth , (brings the music really low and then volume suddenly rises ) Also reading never match when I calibrate . Never had these issues before .
 
Keeps crashing 
I love this app and the Dexcom but since some of the recent updates, the app crashes and I have to reinstall frequently. It’s annoying and frustrating. Please fix!
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of it alarming. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded.
 
Best CGM 
Love Dexcom, love this app!
 
Update crashes 
I’ve been using this app for a while and all has been fine until I updated my iPhone. I haven’t been able to open the app since; it force closes every time I try to open it. I have to go find my old meter now :/
 
Low alert 
Unable to set the low alert to repeat at 5 minutes. I scroll to the 5 minute indicator and when pick my finger up off the screen it rolls back to the 0 minutes reminder. When I try to select 10 minutes, it rolls over to 15 minutes. As I’m sure you are well aware, if I am experiencing a low, I need to know as soon as possible, not in 15 minutes. Sometimes the first alarm doesn’t wake a sleeping person.
 
The Worst Tech! 
Day one of having the app. Alarms go off even when you turn off the specified alarm. (Ex: I turned off the signal loss alarm. It continued to alarm... over and over.) Alarms repeat even if you change the settings, and direct the app not to repeat said alarms. I haven’t seen my daughter’s BG in hours due to signal loss. I had over 20 notifications last night even though I silenced the alarms. I woke up to the first 8.... Long night!!! Upon opening the app: it walked me through each step of the tutorial that we watched when we first got the CGM. (I could skip some of it, so that was nice.) This app could be amazing! It needs LOTS of work. We spend thousands and thousands of dollars on supplies and equipment. The least the company can do is make this user friendly. Please have someone fix the app! Make this great for us!!!!!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?

I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Problematic 
Ever since the new app/ update I’m having the same issues as others . Bluetooth , (brings the music really low and then volume suddenly rises ) Also reading never match when I calibrate . Never had these issues before .
 
Keeps crashing 
I love this app and the Dexcom but since some of the recent updates, the app crashes and I have to reinstall frequently. It’s annoying and frustrating. Please fix!
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of it alarming. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Good, not great 
This app would be greatly improved by allowing corrections to entries when you realize you fat fingered an entry. As it is wrong information is recorded.
 
Dexcom 
I don’t know why people dislike the app it’s very useful
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.

The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
The new new update is a load of garbage 
The new update just doesn’t function completely. I love you guys but, seriously what is this? It functions only periodically and rarely even works. I dont even know what my blood sugar is.
 
New iPhone update causing issue with app on Apple Watch? 
My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Dexcom doesn’t understand what MUTE means. 
Despite having every alert option turned off, my phone on vibrate, and being connected to an Apple Watch this app rings loud enough to wake the deaf. It would be nice if I could discreetly check my blood sugar at work but I have to turn my phone off for fear of ear damaging banshee wails coming from the Dexcom app. I’m surprised people haven’t lost their jobs over the phone overriding nite settings. I wouldn’t keep this on my phone if it wasn’t necessary to send blood sugar data to my watch.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!

My Apple Watch will no longer display my blood sugars and believe it’s a disconnect due to a recent iPhone update. Any solutions?
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.

When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.

Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB, go to email or messages, and start typing. You will get loud popping noises every few keyclick or so. Also, the reduced font size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The lower quality of their releases, and slowness to acknowledge and fix bugs is amazing.
 
Disappointing 
I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Good, but still needs work 
The alert volume is still very loud, and after alert goes off, it leaves the volume on my iPhone to medium when I normally leave it on mute. Please also allow alerts to be dismissed via Apple Watch.
 
Crash, Nuisance Alarms, Doesn't Alarm 
What have you done? This last update is terrible. You fixed the music cutting out issue. What about the issue with the app crashing and closing itself all of the time, what about the constant signal loss alarm when I never lost signal. I even at times get a low glucose alarm about 15 minutes after it happened. Sometimes I get no sound at all even with the alarm always on. You have junked this app up trying to please to many people. You had a much more reliable product two years ago and have significantly went downhill.
 
iPhone 8 Plus - app keeps closing/signal loss 
I just bought a brand new iPhone 8 Plus and downloaded the Dexcom g5 mobil app. However, ever 20 minutes or so I began receiving “signal loss” and “app closed” errors. This is concerning to me because I need to have others following my numbers...my mom was worried thru the night because she was unable to see where my blood glucose numbers were, and I was being woken up thru the night with her calls to check on me. This is a brand new phone, and I can only guess the issue is with the Dexcom g5 application. I have deleted and re-downloaded this app several times, I’ve called Dexcom support several times this morning, and the app continues to be sporadic ... ugh. Please help!!!! I can be reached at any time- thank you, Dawn
 
Love my Dexcom G5 system 
Love my Dexcom G5 system
 
Bluetooth 
I keep having trouble keeping it connected to my Bluetooth. It keeps loosing signal when nothing nearby is affecting it. I replaced the transmitter thinking it would fix the issue but it didn’t. I get random burst of connections throughout the day
 
Good but... 
Please add more alert noises that you can choose from! All but 3 are obnoxious
 
Great app for the most part 
I wish I wouldn’t enter my blood sugar to calibrate and then have the app tell me 15 minutes later that I need to do it again. I thought it only needed calibration every 12 hours.
 
Problems with the new update 
I'll echo what others have talked about the audio being disrupted when I now open the app. This never was a problem with the older version. The more concerning issue with the update is that the app doesn't always allow me to calibrate my glucose levels. The green "Save" button doesn't always show up when I try to input a value
 
Bluetooth Music Issue 
I am also experiencing the issue with music volume. I am surprised Apple approved this version of your app. Very annoying.
 
Amazing 
I no longer test at all, just follow dexcom and my A1C is 6.3 so that proves how well it works, also the best customer service I have ever seen, never any wait time and 24/7 availability, really amazing, thanks!!!
 
Not able to calibrate wirh new version 
keyboard blocks save button. makes app useless.
 
Lost Alerts 
I hate this update. At the times when I should be receiving high glucose alerts, the sound of whatever I'm listening to will fade but the alert won't play. It's incredibly annoying. Thank goodness the low alert still plays.
 
New Update Issues 
I have an iPhone but use the Google Keyboard app as my keyboard and with the most recent update, I am unable to add a blood sugar number with this keyboard active. The green accept/confirm button will not show up so I have to delete the keyboard, use the regular iPhone keyboard to enter my blood sugar, and then re-add the Google keyboard.
 
Update 
The update is a step in the right direction. Being able to schedule your alerts helps, but you still cannot completely silence them, which I understand is maybe a legal matter (I wish the developer would just explain why the alerts can’t be silenced rather than ignore the many requests). I noticed with the new update, while having the Dexcom app run in the background while listening to music, it silences the music as if you’re getting a notification (email, text) but there is no alert. It does this about once every 3 or 4 minutes. It is the Dexcom app causing it, since as soon as I close the Dexcom app the interruptions stop.
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?

I love my Dexcom, but not this app. The app doesn’t give me readings if I don’t update my iPhone as soon as the Apple update comes out. I find this ridiculous. I often go hours without my glucose readings until I have time to do updates.
 
Havoc on an iPhone 7 
Dex is king in the CGM world. I am thankful I can see my blood glucose on my phone. Why a 3 star rating? See below: 1. The app creates chaos with any audio. I use my device to listen to music, almost all day. Anytime a notification pops up, the music gets quiet. Whether there is an audio notification or not. Seriously needs fixed, yesterday. Very very very annoying. It doesn’t matter if it’s a wired or Bluetooth connection. Sometimes the audio will stay quiet like the Dexcom app has super user permissions, so I crank up my music. Well give it a few minutes and bang, the Dexcom app gives up control of the audio and we have unbearably loud music. 2. “Signal loss”. This seems to be getting better over time. However, it still persists from time to time. I’m in range of my devices, and get signal loss messages. Now, it wouldn’t be a big deal, just close the app and reopen it. Nope. I talked with Dexcom, they said to close other apps. WAIT. WHAT?! NO. NO. NO. This isn’t how iOS works. Remember back in the day, when we always closed our apps to “save battery”? Those days are over. iOS and other mobile platforms for that matter have been designed to run all these apps in the background, and allow them to use resources when they are opened back up. 3. Give us the option to silence that darn enter BG notification. Enough said there.
 
Problems with the new update 
I'll echo what others have talked about the audio being disrupted when I now open the app. This never was a problem with the older version. The more concerning issue with the update is that the app doesn't always allow me to calibrate my glucose levels. The green "Save" button doesn't always show up when I try to input a value
 
Bluetooth Music Issue 
I am also experiencing the issue with music volume. I am surprised Apple approved this version of your app. Very annoying.
 
Amazing 
I no longer test at all, just follow dexcom and my A1C is 6.3 so that proves how well it works, also the best customer service I have ever seen, never any wait time and 24/7 availability, really amazing, thanks!!!
 
Not able to calibrate wirh new version 
keyboard blocks save button. makes app useless.
 
Lost Alerts 
I hate this update. At the times when I should be receiving high glucose alerts, the sound of whatever I'm listening to will fade but the alert won't play. It's incredibly annoying. Thank goodness the low alert still plays.
 
New Update Issues 
I have an iPhone but use the Google Keyboard app as my keyboard and with the most recent update, I am unable to add a blood sugar number with this keyboard active. The green accept/confirm button will not show up so I have to delete the keyboard, use the regular iPhone keyboard to enter my blood sugar, and then re-add the Google keyboard.
 
Update 
The update is a step in the right direction. Being able to schedule your alerts helps, but you still cannot completely silence them, which I understand is maybe a legal matter (I wish the developer would just explain why the alerts can’t be silenced rather than ignore the many requests). I noticed with the new update, while having the Dexcom app run in the background while listening to music, it silences the music as if you’re getting a notification (email, text) but there is no alert. It does this about once every 3 or 4 minutes. It is the Dexcom app causing it, since as soon as I close the Dexcom app the interruptions stop.
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Love this App 
I LOVE the Dexcom G5 mobile system. This app is simple, uncluttered and gives me the info that I need right when I need it. I also love that it works with the Apple Watch. It makes getting my BGA easier than I ever thought possible. One feature I’d like to see added. On the Apple Watch version, I wish I had my BGA reading on the watch screen while using my workout app. I use Apple’s Workout, but many people use MapMyRun or NikeRun. All three offer the ability to customize what information shows on the screen during a workout.
 
My Dexcom Experience 
I have been a diabetic for a little over two years now and I have to say that the Dexcom is one of the best things to come into my life. I'm still pretty young and not really fully in control of my diabetes yet. To say the least my Dexcom has helped me lower my A1C from high 12's to now in the range of 8. I would recommend this for anyone trying to lower their A1C. I've also found a product called "Grifter Grips" which helps keep my device on as I live and active lifestyle and am always morning twisting and running.
 
App quality going down/first resolve audio/KB issue 
This latest release that was supposed to fix the audio and keyboard issues doesn't. They are still there. Just install Google KB and start typing. You will get loud popping noises Endo few keyclick or so. Also, the reduced don't size for menus makes them hard to read for the elderly and vision impaired. The menus do not respond to font size adjusting in accessibility. The quality of their releases, and slowness to acknowledge and bugs is amazing.
 
Bug! 
This update means the app is no longer working for me. When I enter the BG value there is no enter button! What happened?
 
I second Itoig’s review. 
I am having the same exact issue. You may have app developer call me to discuss. Tim 310 874 8054
 
Can no longer calibrate 
After this update the button to submit my calibrations doesn’t show up so I can’t enter my blood sugar

I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Bug! 
This update means the app is no longer working for me. When I enter the BG value there is no enter button! What happened?
 
I second Itoig’s review. 
I am having the same exact issue. You may have app developer call me to discuss. Tim 310 874 8054
 
Can no longer calibrate 
After this update the button to submit my calibrations doesn’t show up so I can’t enter my blood sugar
 
Havoc on an iPhone 7 
Dex is king in the CGM world. I am thankful I can see my blood glucose on my phone. Why a 3 star rating? See below: 1. The app creates chaos with any audio. I use my device to listen to music, almost all day. Anytime a notification pops up, the music gets quiet. Whether there is an audio notification or not. Seriously needs fixed, yesterday. Very very very annoying. It doesn’t matter if it’s a wired or Bluetooth connection. Sometimes the audio will stay quiet like the Dexcom app has super user permissions, so I crank up my music. Well give it a few minutes and bang, the Dexcom app gives up control of the audio and we have unbearably loud music. 2. “Signal loss”. This seems to be getting better over time. However, it still persists from time to time. I’m in range of my devices, and get signal loss messages. Now, it wouldn’t be a big deal, just close the app and reopen it. Nope. I talked with Dexcom, they said to close other apps. WAIT. WHAT?! NO. NO. NO. This isn’t how iOS works. Remember back in the day, when we always closed our apps to “save battery”? Those days are over. iOS and other mobile platforms for that matter have been designed to run all these apps in the background, and allow them to use resources when they are opened back up. 3. Give us the option to silence that darn enter BG notification. Enough said there.
 
Problems with the new update 
I'll echo what others have talked about the audio being disrupted when I now open the app. This never was a problem with the older version. The more concerning issue with the update is that the app doesn't always allow me to calibrate my glucose levels. The green "Save" button doesn't always show up when I try to input a value
 
Bluetooth Music Issue 
I am also experiencing the issue with music volume. I am surprised Apple approved this version of your app. Very annoying.
 
Amazing 
I no longer test at all, just follow dexcom and my A1C is 6.3 so that proves how well it works, also the best customer service I have ever seen, never any wait time and 24/7 availability, really amazing, thanks!!!
 
Not able to calibrate wirh new version 
keyboard blocks save button. makes app useless.
 
Lost Alerts 
I hate this update. At the times when I should be receiving high glucose alerts, the sound of whatever I'm listening to will fade but the alert won't play. It's incredibly annoying. Thank goodness the low alert still plays.
 
New Update Issues 
I have an iPhone but use the Google Keyboard app as my keyboard and with the most recent update, I am unable to add a blood sugar number with this keyboard active. The green accept/confirm button will not show up so I have to delete the keyboard, use the regular iPhone keyboard to enter my blood sugar, and then re-add the Google keyboard.
 
Update 
The update is a step in the right direction. Being able to schedule your alerts helps, but you still cannot completely silence them, which I understand is maybe a legal matter (I wish the developer would just explain why the alerts can’t be silenced rather than ignore the many requests). I noticed with the new update, while having the Dexcom app run in the background while listening to music, it silences the music as if you’re getting a notification (email, text) but there is no alert. It does this about once every 3 or 4 minutes. It is the Dexcom app causing it, since as soon as I close the Dexcom app the interruptions stop.
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.

It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Signal loss 
I’m always getting a signal loss alert even when my phone is right next to the sensor.
 
Can’t use the app when it can’t connect to server.. 
I don’t like that I have to login in order to use the app!! App won’t let me login due to server connection issues?? Why? I thought it was my password, so I tried to change it but I get the same error! Can you add the ability to skip the login part? What if I didn’t have WiFi or data?
 
Fixed! 
Updated 3-23-18. The latest update has repaired all issues reported below on a X. Calibration entry problems and time delays on logging issues are fixed, so thx to the dev team for getting it fixed. Now, if only we could get the direct to Apple Watch display feature released we would be at five star place. -–----------------- Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Watch 
So this is more of a question rather then a review. Can you cancel out the alarms from the new watch? And can you leave the phone at home and the sensor still work?
 
App finally updated! 
Phew, took em long enough but I can at last use this app on my iPhone X.
 
Appreciate the new schedule feature for alarms 
In general dexcom works great. I wouldn’t want to go without it. The recently added schedule for alarms and the ability to silence or allow the alarm to go with the phone volume is very helpful. I have it set to follow my phone volume during the day at work and have a schedule for override when I am home and at night. This flexibility is very useful. Would love to be able to dismiss alarms through watch.
 
Disappointed in Update 
The update to 1.7.5 just came out and not only is it buggy but it’s affecting my music. Prior to the update, I could open the dexcom app, get alerts, etc without the app affecting my music. Now the app lowers my music volume if i get an alert (even when i have my alerts silenced) and stops my music completely when I open the app. If I try to calibrate, my number pad appears MAYBE 25% of the time. I couldn’t even calibrate 3 times without completely closing the app and reopening it. When I spoke with Dexcom a MONTH ago, I was told the app was ready for the update but they were waiting for apple to finish their security updates. Obviously this app wasn’t fully tested for bugs and is now turning into more of an annoyance than anything. Additionally, with the launch of the new apple watch with cellular data, dexcom is supposedly coming out with an update to link directly to the watch. Considering it took 4 months to do an update for the new iOs I can’t imagine how much longer it will take dexcom to come out with that update AND a fix for the bugs on this update. I am highly disappointed in dexcom. The only reason I’m not going back to using the standalone receiver is because I don’t want another thing I need to carry. This needs to be fixed Edit: i got a response asking for me to send my info to dexcom so they can contact me. I emailed them my info and haven’t heard from anyone. The Dexcom app is affecting all sound on my phone, the alerts only sometimes work on my watch, the calibration screen is buggy and the fact that it took months for dexcom to push out a buggy terrible app is absolutely ridiculous. I’m at the point where I’d rather just not use my dexcom until these issues have been fixed.
 
Love my Dexcom 
I live my Dexcom CGM and it’s app. One big problem: I too am having the same problem as itoig pointed out in their review. Whenever I’m listening to music or books the volume goes down every five minutes for ten seconds. It is very annoying. I called tech support and they said to just turn off alerts when I’m listening to music. That response was instantly dismissed by me because I’m not going to switch buttons on and off all day long. I know you’ll find and squash this bug. Please do it quickly. Thank you for listening to reviewers and keep up the good work at Dexcom.
 
Uncle to log sugars now 
I JUST did the update & it will let me type my reading in but will not allow me to save it. I tried closing the app & reopening it, but it still isn't working!
 
Volume problem 
I have the same issue as user ltiog My music audio quiets down and goes back up frequently. Can I install a previous version of the dexcom app?
 
Bug! 
This update means the app is no longer working for me. When I enter the BG value there is no enter button! What happened?
 
I second Itoig’s review. 
I am having the same exact issue. You may have app developer call me to discuss. Tim 310 874 8054
 
Can no longer calibrate 
After this update the button to submit my calibrations doesn’t show up so I can’t enter my blood sugar
 
Havoc on an iPhone 7 
Dex is king in the CGM world. I am thankful I can see my blood glucose on my phone. Why a 3 star rating? See below: 1. The app creates chaos with any audio. I use my device to listen to music, almost all day. Anytime a notification pops up, the music gets quiet. Whether there is an audio notification or not. Seriously needs fixed, yesterday. Very very very annoying. It doesn’t matter if it’s a wired or Bluetooth connection. Sometimes the audio will stay quiet like the Dexcom app has super user permissions, so I crank up my music. Well give it a few minutes and bang, the Dexcom app gives up control of the audio and we have unbearably loud music. 2. “Signal loss”. This seems to be getting better over time. However, it still persists from time to time. I’m in range of my devices, and get signal loss messages. Now, it wouldn’t be a big deal, just close the app and reopen it. Nope. I talked with Dexcom, they said to close other apps. WAIT. WHAT?! NO. NO. NO. This isn’t how iOS works. Remember back in the day, when we always closed our apps to “save battery”? Those days are over. iOS and other mobile platforms for that matter have been designed to run all these apps in the background, and allow them to use resources when they are opened back up. 3. Give us the option to silence that darn enter BG notification. Enough said there.
 
Problems with the new update 
I'll echo what others have talked about the audio being disrupted when I now open the app. This never was a problem with the older version. The more concerning issue with the update is that the app doesn't always allow me to calibrate my glucose levels. The green "Save" button doesn't always show up when I try to input a value
 
Bluetooth Music Issue 
I am also experiencing the issue with music volume. I am surprised Apple approved this version of your app. Very annoying.
 
Amazing 
I no longer test at all, just follow dexcom and my A1C is 6.3 so that proves how well it works, also the best customer service I have ever seen, never any wait time and 24/7 availability, really amazing, thanks!!!
 
Not able to calibrate wirh new version 
keyboard blocks save button. makes app useless.
 
Lost Alerts 
I hate this update. At the times when I should be receiving high glucose alerts, the sound of whatever I'm listening to will fade but the alert won't play. It's incredibly annoying. Thank goodness the low alert still plays.
 
New Update Issues 
I have an iPhone but use the Google Keyboard app as my keyboard and with the most recent update, I am unable to add a blood sugar number with this keyboard active. The green accept/confirm button will not show up so I have to delete the keyboard, use the regular iPhone keyboard to enter my blood sugar, and then re-add the Google keyboard.
 
Update 
The update is a step in the right direction. Being able to schedule your alerts helps, but you still cannot completely silence them, which I understand is maybe a legal matter (I wish the developer would just explain why the alerts can’t be silenced rather than ignore the many requests). I noticed with the new update, while having the Dexcom app run in the background while listening to music, it silences the music as if you’re getting a notification (email, text) but there is no alert. It does this about once every 3 or 4 minutes. It is the Dexcom app causing it, since as soon as I close the Dexcom app the interruptions stop.
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
Appreciate the new schedule feature for alarms 
In general dexcom works great. I wouldn’t want to go without it. The recently added schedule for alarms and the ability to silence or allow the alarm to go with the phone volume is very helpful. I have it set to follow my phone volume during the day at work and have a schedule for override when I am home and at night. This flexibility is very useful.

Those days are over. iOS and other mobile platforms for that matter have been designed to run all these apps in the background, and allow them to use resources when they are opened back up. 3. Give us the option to silence that darn enter BG notification. Enough said there.
 
Problems with the new update 
I'll echo what others have talked about the audio being disrupted when I now open the app. This never was a problem with the older version. The more concerning issue with the update is that the app doesn't always allow me to calibrate my glucose levels. The green "Save" button doesn't always show up when I try to input a value
 
Bluetooth Music Issue 
I am also experiencing the issue with music volume. I am surprised Apple approved this version of your app. Very annoying.
 
Amazing 
I no longer test at all, just follow dexcom and my A1C is 6.3 so that proves how well it works, also the best customer service I have ever seen, never any wait time and 24/7 availability, really amazing, thanks!!!
 
Not able to calibrate wirh new version 
keyboard blocks save button. makes app useless.
 
Lost Alerts 
I hate this update. At the times when I should be receiving high glucose alerts, the sound of whatever I'm listening to will fade but the alert won't play. It's incredibly annoying. Thank goodness the low alert still plays.
 
New Update Issues 
I have an iPhone but use the Google Keyboard app as my keyboard and with the most recent update, I am unable to add a blood sugar number with this keyboard active. The green accept/confirm button will not show up so I have to delete the keyboard, use the regular iPhone keyboard to enter my blood sugar, and then re-add the Google keyboard.
 
Update 
The update is a step in the right direction. Being able to schedule your alerts helps, but you still cannot completely silence them, which I understand is maybe a legal matter (I wish the developer would just explain why the alerts can’t be silenced rather than ignore the many requests). I noticed with the new update, while having the Dexcom app run in the background while listening to music, it silences the music as if you’re getting a notification (email, text) but there is no alert. It does this about once every 3 or 4 minutes. It is the Dexcom app causing it, since as soon as I close the Dexcom app the interruptions stop.
 
Inadequate, Inexcusable, Underdeveloped Mess 
I want to love dexcom, but the phone app is disastrous, inadequate mess. 1) The button to update your blood sugar keeps disappearing, I have to wait until whenever the button returns and re-test, wasting strips. I have to walk around uncalibrated with inaccurate numbers at least four days a week due to this. 2) Almost all test machines give readings up to 500 or 600, dexcom only goes to 400. Sometimes I have no idea what my blood sugar is because dexcom just says "high." The scale MUST go to at least 500, it simply doesn't match to other products in the industry and people like me with recurrent hyperglycemia really need that information. 3) The fact that you can only set 100 as your urgent low is AWFUL. I drop super quickly, if I find out I'm low at 100, I have roughly five minutes to correct that before I become incapacitated. Dexcom needs to allow users to set their low alert wherever they need it. It's not inclusive to create software only for well controlled people. This has been the biggest disappointment of the dexcom and it almost defeats the purpose of having I. I only know what's happening once it's already dangerous. Why even have it? 4) Also, I know the paper in the sensor packages states the missing alarm for quick drops and urgent lows is fixed, but I still have this problem. Dexcom is SO PERSISTENT about highs and so touch and go about lows, which need more urgent addressing! Inexcusable.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better (less intrusive, more user friendly, etc.) when it first came out. Update: the calibration schedule is still at the mysterious hands of the app. I'd like to be able to calibrate when I check. Especially when the numbers reported by the app are 60 points off.
 
Life Saving App 
This Application has literally saved my life more times than I can count!! The previous update really had some issues but I'm really loving this new update!! It fixes a number of the super frustrating issues on the last version!! Love Dexcom!! Give it a shot and understand that this is still a developing technology but you can't get better than Dexcom!!
 
Calibration screen problems 
I got the iPhone X a week ago and ever since I upgraded, the save and cancel buttons will not appear on my calibration screen. This has been very frustrating because I keep getting notifications to enter my recent blood sugars but am not able to do so because of this problem. I have not been able to use my dexcom because the blood glucose that is shown on the app is nowhere close to the number my glucose meter says and, therefore, is currently useless.
 
Alerts 
I loved the idea of being able to silence the alerts during school and just have the pop up notification go to my watch. However, it only works once in a while. I’ll have the “always sound” turned off but the alerts will still go off loudly. When it does actually work it is nice because then I don’t have to change the alert sounds to vibrate only (vibrate only doesn’t work either, my phone won’t vibrate I only get the pop up notification). If this feature could be fixed so that alerts won’t actually sound when you don’t want them to it would be great. Edit: I have also noticed that my music fades out every time my blood sugar is checked. It is really irritating since it happens every 5 minutes so hopefully that can be fixed in the next update.
 
Update 
New update fixed all issues!
 
Same volume issue as Itoig 
Itoig- thanks for figuring out the issue! I’ve been having the same problem and it was making me crazy. I couldn’t figure it out since I don’t alarm thru my phone, only my receiver. It is quite annoying!
 
It’s ok… 
I’m having a current problem of my readings not showing but just the 3 question mark symbol all day until it reads for a little while and then goes back to not reading
 
Thanks for the alarm fix!! 
The 1.7.6 update fixed the alarm issue. Appreciate the quick response! One of the reasons for choosing Dexcom for my CGM, was the attentiveness to smartphone technology. I love having you on my team! Keep up the good work!
 
Update/music interference 
New update still has a conflict with Bluetooth music as well as Apple Carplay when hooked up direct with USB.
 
Volume issues on playback and keyboard not displaying 
Great app ... Too bright Volume issues on playback and keyboard not displaying title says it all. Now an update is available in app but not in store. Nice.
 
Problem solved 
Thank you for listening to Customers and resolving the audio issue so quickly!
 
Still not fixed 
The latest update did not fix the issue with the volume while using CarPlay. Still very annoyed.
 
Stay away 
I bought into the Dexcom GMS because of the app that allowed me to monitor and dose using the readings on my phone. This has been a joke. I almost never get numbers because the app doesn’t work. I called Dexcom and all they wanted to do was blame Apple’s operating system. They didn’t own it at all. Hey Dexcom, they are your partner in this. Work it out and don’t pass the buck. I want all of my money back for the useless medical supplies I bought because your tech people don’t know how to update for new versions of the iOS and your customer service reps who could care less. This is why Medtronic is eating your lunch. I never should have left them.
 
Bionic Woman in the Making 
With this and my OmniPod insulin pump I feel ALMOST “normal”. I haven’t had such good A1c results ever as a diabetic. This thing definitely doesn’t let you off the hook with keeping your sugars in check. And it’s saved my life a couple of times. The best part is driving on our road trips or walking around Disney and not worrying about checking every couple hours. My daughter or husband can look at my phone or I can glance at my watch and know exactly how I’m doing. I wish I could get involved and start a foundation that provided this tech to all Type 1 diabetic kids. That would be amazing for them and their parents. #diawarriors
 
Thanks for fixing the sound issue so quickly! 
The app is great! Also, I appreciate how quickly the sound bug that occurred in the last version was fixed.
 
It’s ok 
I’ve had Dexcom’s app since it first entered the iTunes Store for the G5. I loved it then, but not as much now. Updates happen, and they keep lowering the usability if he app. Overall, the system works well, but each update seems to make it a little bit worse or more annoying. If I could go back 2 years to the app I had then, I would do it. It makes one want to try alternatives like Spike in order to gain more user control.
 
Conflict with Bluetooth music 
I agree with the last reviewer. The new update causes my music to turn off completely when I am listing to a Bluetooth speaker. I hope you can take care of this in the next update. Thanks because I really enjoy my Dexcom G5
 
Stupid updates 
Why is it that you listen to customer feedback to fix a sound issue that interrupts music in headphones but you won’t listen to customers screaming that you should fix the mute override sound issue when it disrupts my entire office with it’s unnecessary beeping? The app is great in alerting me once that I have a low blood sugar. So I drink a bottle of coke to fix it. The app is TERRIBLE in continuing to remind the entire free world that I had a low blood sugar and is on a 30 min lag in recognizing that I’ve already addressed the situation!!!
 
Sound off 
New Review: The sound issue has finally been fixed however this update created a problem where the app looses connection with the transmitter until you open the app. Then weirdly the hours of lost data will reappear. This needs to be fixed ASAP because I woke up this morning with a 40 sugar but no alert because the app lost connection. Old Review: The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
So much promise - such a failure!! 
2018 update: Guys - please read these reviews and fix these flaws. I love DexCom, it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why don’t alerts stay dismissed? I get reminded every 10 mins that my glucose is high. 4. Why are there almost no tangible improvements to the app in 3 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. 2016 Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Update Mar 2018: IT GOT WORSE AGAIN! REALLY IT DID. Honestly, I read these reviews and none of the problems identified over the years seem to get fixed, new bugs seem to crop up. Eg: 1) the audio volume problem mentioned multiple times 2) dismissing alarms don’t stay dismissed for the selected times 3) there is now no warning that the sensor will expire in x hours, the y hours, etc. Now, suddenly I find that the sensor needs to be replaced immediately. 4) the list goes on and on.... I think we’d all be better off with the 2016 version, as flawed as it was. It’s time to FIRE someone and hire a new head of this project. Apple would never accept this shoddy work for 2 months let alone 2-3 years. This is how your users interact with the product and it is a horrid customer experience if you look at these rating. WAKE-UP and smell the coffee!! Please. Abbot is coming with a great new device. Get this part of your system fixed.
 
Buggy app with slow development 
** 3/14/18 update ** Finally the audio bug is fixed. Now waiting on a more stable Apple Watch complication and hopefully a direct connection to the Apple Watch (series 3) using core Bluetooth functionality. **Original review ** Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Frustrated by latest update 
Since I installed the latest dexcom update, the app on my Apple Watch does not work the same. This is incredibly frustrating as the dexcom app is 90% of the reason why I even have the watch. Since the update, my blood sugars are not showing on the watch face widget. I just see three dashed lines. If I tap the icon to open the app, I’d say about 25% of the time the graph will show up with my blood sugar reading, 50% of the time the graph just hangs and no number shows up, and 25% of the time I get a message that pops up and says “check G5 mobile app on iPhone.” Please fix this!! And test better before you release an update to an app that people rely on for their health. Irresponsible.
 
Annoying 
The whole alerting thing is annoying, to say the least, and I end up turning off my phone more frequently. As long as there is no total sound off setting, this app remains unusable.
 
Full Apple Watch Support? 
App is fine, even better since the latest fixes and update. Around September or October of 2017, I read many articles about Dexcom along the transmitter to send your blood glucose directly to the Apple Watch instead of having to go through the phone first. This would allow those of us who exercise not to have to take our phone with us. I spoke to a Dexcom rep in November 2017 who told me that it should happen around December 2017 or January 2018. Since then, I have heard nothing about it. Is Dexcom going to allow the transmitter to send my blood glucose directly to my Apple Watch or has the idea been ditched?
 
Can’t enter BG reading-FIXED THANK YOU!! 
This app was working fine for me until recently. Now I’m encountering occasional problem where I cannot enter my readings because the SAVE button disappeared. It’s happened 3 times now. The first 2 times it finally just came back the next day. So far that’s not happening this time. Very frustrating... it tells me to enter a reading and I can’t. I just want it to work like it used to. PLEASE FIX THIS ASAP! ! BIG THANKS guys for getting this fixed so quickly. The update you provided Friday worked like a charm.
 
Worked to Fix Latest Bugs 
Changing my rating to 4 stars because Dexcom went out of their way to call me, explain the issue with custom keyboards, and promise me a fix was on the way. Glad to see they followed through.
 
Love it 
So convenient to just look at my phone and see my blood sugar
 
Volume can’t be controlled 
The app raises your question phone volume to 100% to play alerts like calibration required. You can actually see the volume indicator pop up on screen. It’s just unacceptable that this behavior can’t be configured or disabled. It’s my phone, my expensive CGM, my medical condition... I don’t need someone else imposing this kind of crap on me. I can appreciate that some people whine about missing alerts, but what happened to personal responsibility?
 
New update has messed with my transmitter working 
This newest update has really Messed up my transmitter. Ever since the update, the entire function of my Dexcom does not work. I’ve contacted Dexcom and they’ve sent me a brand new transmitter and this doesn’t work now. Technical support on their has no answers. They think it could also be the new Apple update that is not functioning with the Dexcom. Great! Now, I have no functioning of my cgm. What a waste of $8000!!! 😔
 
Great App and really useful 
I love the Dexcom app! It makes monitoring my blood sugars so easy! My only advice would be to update the icon for the app. Native iOS apps like calendar and the clock app have a dynamic icon that actually displays the day/date and current time on the icon. It would be cool if the icon for Dexcom did the same thing so that users could just have a quick glance at their phone to see what their BG is and the current trend without having to actually open the app.
 
Only 3 hour review? 
I love love love being able to track my sugars via my phone/watch, but on my phone I can only see the past 3 hours of data? I used to be able to turn it sideways and get 1-24 hour ranges but I can’t seem to do that anymore. Any suggestions?
 
What did you do?!???? 
The most recent update now continues urgent low alarming even after a low is resolved and the app is closed..... for hours. Thanks Dexcom your app has now caused me another sleepless night. Not only am I considering removing the app, but also ripping the whole device from my body. PLEASE FIX IT!
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c. UPDATE 3/22/18: I found Dexcom Clarity, which does all of the reporting I was looking for, here comes that last star!
 
GBoard Issue 
When entering blood glucose logs using Google’s GBoard, the ‘save’ button doesn’t adjust up above the keyboard to allow me to complete the log. I have to subsequently delete my GBoard every time I enter a BG, which is frustrating. Hope to see this fixed in the next update. Thanks!
 
Update isn't work! 
UPDATE: Right now it won't work correctly, and even after turning off all alerts (besides the urgent low which you can't turn off) and it keeps beeping at me, and my glucose is 120, I'm really frustrated. These are only audible through a Bluetooth connection, you hear nothing unless it's connected to my speaker or headphones. I So the new update introduced a couple nice features, but it is causing my Bluetooth streaming music to have constant interruption. Beeps when it's silenced, mutes my music even if no alert should be sounding, and adjusts my volume. I have also had issues where the 'enter' and 'cancel' buttons are not visible on occasion. This has cost me 6 extra finger sticks this week alone. The buttons end up coming back but only later when the glucose value is no longer valuable. The old app was better, and if I could switch back I would. The new functionality isn't worth these hassle.
 
Interrupting my music/audio 
There’s a weird bug that’s causing the volume of my music to lower for a few seconds. I suppose this happens when the app is gathering data. It seems I am not the only person with this issue.
 
Love the app, new update has issues 
This is the most used app I have. I absolutely love the technology. The most recent update is causing issues when I stream music on my phone. I travel extensively for work and spend the majority of my time in my car and any time I check my blood sugar values on the app (I keep the app running while driving along with my Amazon Prime music and Google Maps) I lose all audio. Please be aware that the new update is doing this.
 
Unable to enter by meter value 
Unable to enter by meter value
 
Some issues 
The app takes over the sound on my iPhone when it's open.
 
You broke it. 
Horrible update. I can no longer calibrate my sensor because the green enter button no longer appears on the calibration screen. For the love of God, please roll back this update until you fix the problem.
 
Unable to enter BG values👎🏼 
Update 2/26: the inability to enter BG values continues....since I'm not able to calibrate, I have had many inaccurate readings from my CGM that have caused issues. Please fix asap! Dexcom 1.7.5/iPhone X -----------------------------— Update: after rebooting my iPhone several times and reinstalling the app, I can enter BG values again. Also glad that alarms can be silenced now! _____________________ I love my G5 but after the latest app update (1.7.5) - I'm not able to enter glucometer readings since the submit/enter button is gone. Hope you fix this ASAP since it's worthless without the ability to calibrate!!
 
BAD Update; Don’t if you haven’t yet! 
If you haven’t updated to version 1.75, don’t. That is unless you don’t use your phone to listen to audio or any sort - at least on iOS. Normally when you get a notification on an iPhone, the OS will compress the sound of whatever audio you’re listening to (music, YouTube videos, etc.) for 2-5 seconds, and this is referred to as “ducking”. After this update, the Dexcom App will cause ducking intermittently even when there’s no notification. I don’t use the app’s sounds as it is since vibrate works fine for me. Since Dexcom only releases updates every 2-3 months, I deleted this version, and reverted to version 1.71 using the backup I created in iTunes (on my computer) last month. This definitely needs to be fixed FAST. I can’t believe they released this update without noticing this 👎
 
Awesome cgm, terrible app update 
I loved the Dexcom cgm and app, but the update has made me unable to to calibrate. It lets you enter your bg, but you can not hit "okay". You also can not exit the calibration screen without closing the entire app. Also, when using Bluetooth audio, it randomly cuts out every few minutes. This needs to be fixed ASAP... The calibration issue is dangerous. Let us go back to the older version. This new one is really disrupting things!!
 
SCREEN BLOCKED- Can't Enter BGs!!!! 
Since updating I am unable to consistently enter blood sugar calibrations. The SAVE button either doesn't appear or is blocked by the keyboard on the enter blood sugar screen. This renders the app useless, as I am unable to enter calibrations! PLEASE FIX - I have emailed technical support twice! And have yet to hear back from Dexcom at all.
 
Seriously? 
For a product that’s changing the medical playing field why is this app such a piece of garbage? For a product that is raking in massive amounts of cash why can’t you hire a team to fix all the glitches that literally EVERYONE is complaining about??
 
Messes with Volume 
The new app causes the volume on the phone to reduce for a few seconds randomly while listening to music. It’s beyond annoying. It will also completely reduce the volume if you are in the app itself.
 
Needs fixed!! 
When are you gonna fix this app!! Can't enter a calibration BGL most of the time!!!
 
New update 
Like using this app. However planning on deleting it if the music doesn’t get fixed. I can listen to any music apps without it randomly turning down then going back up. Only started after this Dexcom update.... please fix ASAP!!!!!!
 
Would annotation feature 
Just started with this works well, although can only pair with one smart device at a time. but with iPhone works well. only thing I can think of would make it better is ability to annotate the log/graph of bs measurements over time, so could more easily look back and see bs rise/fall following food or injection
 
Nope. Doesn't calibrate reliably. 
Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Volume control issues 
I’m also having volume control issues with the most recent update. Please fix this issue Dexcom!!
 
A terrible app for a great device 
I'm going to leave the dexcom hardware out of this. I love the dexcom hardware. The app however is a different story. Updates are, at best, slow moving. Most companies are able to release weekly or even more frequent updates but Dexcom's updates are close to every six months. They severely lag behind ape updates which can cause bugs and issues. Dexcom's claim that apple is slowing down their updates is crazy. They need to hire significantly better software developers if they're struggling this badly to keep up. The most recent issue with the app is that after their update, you can no longer use third party keyboards and your dexcom app at the same time. Most company's response would be to apologize and prioritize a quick patch update that solves the issue. Not Dexcom. "We know this is an issue, it may or may not be fixed.". Given their usual timeline I would expect that if their is a resolution it will take six months or longer. It's a shame to see such an amazing device be held back by a very poor software team. Due to their unwillingness to be responsive and efficient, I'd say 1 star is fair. If they start to address issues more rapidly and are more transparent with customers about fixes, I will adjust my review accordingly.
 
What is up with this buggy app 
Why are the open source apps so much better? I don't have a button to submit my calibration after the two hour warm up.
 
Audio issues with the latest update 
As others have noted, the latest update causes incredibly annoying audio interruptions when triggering notifications. When playing audio via Bluetooth, the moment any notification from the Dexcom app is received the audio (at least from the Podcasts app) pauses and then resumes about ten seconds later. Apps playing audio that do not pause (YouTube, or the Music player) instead have their volume nearly muted for that time span. This is an extreme oversight by the developers, and makes using the Dexcom CGM, which is otherwise fantastic, incredibly annoying. Please fix this quickly, before I'm tempted to just kill the app every time I get in the car so I can enjoy listening to podcasts during my commute!
 
Bluetooth listening interrupted 
Like the previous reviewer, my Bluetooth podcast listening is interrupted by this app and the latest update. Every 5 minutes the audio stream pauses for 6 seconds, then resumes. This behavior started when I updated this app. I tried removing the app and the interruptions stopped. The behavior is fairly well-behaved in that the audio stream usually starts up by itself, but it’s a bit annoying to have it keep pausing. Is there some way to fix this? Or is it a factor of IOS Bluetooth & sharing with another app?
 
Works well; Improved alert options 
Love the sensor and now the app. The February ‘18 release fixes the lack of alert options. Update to review after using for a week: Switching to the Dexcom app mutes any sounds already playing, such as streaming audio. It shouldn’t. The alternate schedule doesn’t turn off the alert sounds. Maybe some better help to clarify in case I don’t understand how to use it. The silent mode button does turn off the alerts. Good.
 
Better bit some bugs 
I love the new update. I’ve been waiting for something like this and I am happy with the idea. More schedules? Maybe? I’m just happy with more than one so far. But I hope you fix the sound issue soon. If I open the app to acknowledge an alarm, all music stops. Small bug. I hope you are working on it and update with a fix soon.
 
Sigh 
So when I try to update my blood sugar I'm sent to a screen without a back or submit button. So a useless dead end. The alert schedule feature is confusing and doesn't appear to work (I updated my non scheduled alerts to give me hypo alerts at 90 and all the sudden even though I was in the scheduled window as indicated by the alert icon on main screen, I was getting hypo alerts at 90 - scheduled alerts have hypos at 80.) Should be able to define multiple time windows. Should be able to edit those settings easily. Should not see all those settings on one page, nest the full details yo. Should be able to manually start a mode (movie theater. Class. Whatever). Also design is still, sorry to say it, so ugly. Push harder! Your hardwear is the best, shouldn't your software be too?
 
Can't CALIBRATE! FIX THIS!!' 
We can't CALIBRATE because the acreen's Save button gets covered by the keyboard. This destroys the utility of an incredibly expensive product. Fix this.
 
Great device, terrible update 
Like other reviewers here, I too am having audio problems on my phone with this update. Volume lowers then rises, the sound of typing rises and falls and now other even video volume is being affected. Please fix this issue!
 
Lazy Design with tons of bugs 
There’s clearly no QA that goes into the design of this app as we get pushed out rate updates that seem to actually make the app less functional (the most recent one reminding me I have diabetes every 5 seconds by spontaneously lowering my music) Dexcom should start hiring diabetics to design their apps so it gets actual effort put into it. Alarms are annoying and cannot be disabled in many cases. You can only set limited alert thresholds so if you want to know your blood sugar but don’t want to have an alarm screaming in your ear you’re tough out of luck. I wish the team developing this put half as much effort as I do trying to stay alive every day.
 
How much was this last release tested? 
SOLID app until this last release. I have read some of the other issues people are experiencing. My issue is that if I am listening to anything on my phone and I open the app, it pauses the audio. Many times I don’t even have to open the app (running in background with phone locked) and it will just randomly pause whatever is playing whether it is music or an audiobook. Until it is fixed I will just keep my finger ready to hit the play button many times as my music and audiobooks are paused. And yes, I have already worked with support and the only provided solution was to uninstall the app, reboot my phone, and reinstall it. Doing this three times did not resolve the issue. Also, this is another attempt at what seems like a pretty straightforward feature request. I am not always in a position to calibrate when the 12 hour calibration alert appears. It would make sense to be able to select “remind me in 30 min”, “remind me in 1 hr”, etc. Instead you just get alerted every five or so minutes.
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c.
 
Loses connectivity 
Constantly loses connection.
 
Can't add Blood Sugars most of the time 
Most of the time, when you go to enter a blood sugar, you are not able to collapse the number entry which is blocking the save option. This should have been pointed out in the development process ASAP.
 
User should have the choice on alarms 
The sensor is great. The app is not. Super annoying that the app pauses music and podcasts now when it opens up. The app also should not override do not disturb mode when trying to get a first blood sugar. That’s not a time sensitive/emergent step like urgent low glucose.
 
Apple Watch app needs improvement. 
I like the app. It’s not very customizable and there isn’t any data aside from your current number. But it works well. The Apple Watch app, however, could use some major improvement. First of all, it doesn’t actually update on my watch face. Half the time it’s just a line and the other half of the time it is an old number. I have to touch it to open the app to get an updated number. Defeats the purpose of having it on my watch. Another thing is that I can’t silence alarms from my watch! I have to get up and get my phone or dog it out of my purse to shut the alarm off. Extremely inconvenient.
 
App does not work on iPhone X. 
Save button is hidden when trying to enter blood sugar in app. App is unusable on this device. Dexcom tech support was contacted prior to posting this review. A response has not been received.
 
Sharing is Confusing 
The website says you can now share from the app, but I see no way to do that.
 
Music Interference 
I too am experiencing interference from the Dexcom app when playing music. Very annoying and needs to be fixed ASAP. And maybe consider testing a bit more before releasing updates. I know that sounds kind of snarky but come on, testing interaction with common Bluetooth apps seems like a no brainer. Also would like to have full control over alerts. The low alert at 55 is way too high for me. Maybe that’s a good spot for others? Here again I just want control over it. Otherwise this is a fantastic product. It checks 9 out 10 boxes. Well maybe 8 out of 10 with the music issue.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better when it first came out.
 
Terribly Buggy 
For an app that is essential to my health, I'm highly dissatisfied with how poorly coded it is. For example, I am currently not able to input any values due to an interface error.
 
Dexcom going downhill ... 
After the new update, I constantly experience signal loss. I truly believe my A1c was negatively effected by the app problems. Also, the mandatory alerts need to be changed. I understand that Dexcom is afraid of the liability from missed alerts, but I would gladly sign a waiver to turn them off. So incredibly annoying. I do appreciate that the sensor has memory now so that I am able to see my blood sugars when the “signal” returns but I highly doubt that that is because of the app. Let me be clear: Dexcom hardware and CGM technology was life changing for me. BUT, the hassle with the software now has me considering a different product.
 
Broken application with 3rd party keyboard 
You can’t calibrate with a 3rd party keyboard like Gboard installed. I have to literally force close the app, delete the keyboard and try again. How does that make it through testing? This is 0 star worthy if I could even select that.
 
Frustrated!! 
I've been using this app for less than a week now. Was very happy with it until Saturday when it asked for calibration but when I put in the number I didn't have an ability to enter it, it just stayed in the screen to add the number. Tried MULTIPLE times without success so I deleted the app and reinstalled but don't remember the password. Sent a request for new password and now every time I do I get a message saying that you're having trouble with the server.... I'm sooo frustrated! Please help!!
 
Very good, but ... 
I’ve had this app for maybe a year and find it incredibly helpful. The concept and interface are great! With this recent update, though, I’ve run into two problems. First, as another user noted, if I listen to something on headphones while the app is running, my audio will occasionally fade and cut for 5 or 10 seconds before returning. And second, the app will sometimes freeze in landscape mode regardless of my phone’s orientation. These problems aren’t deal-breakers. I like this app a lot. Im just looking forward to another update to work these problems out.
 
Fix the sound issue and stop ruining Spotify 
I cannot be having the volume to my Spotify go down every five minutes. Next time you update the app (which better be soon or I’m gonna stop using my sensor) you need to actually test it before pushing it out to everyone. I pay WAY TOO MUCH for Dexcom prescriptions to be having this issue. Update: why do you want to follow up with me? Stop wasting your money and staff resources following up with people who already told you what needs to be fixed and just fix it!
 
Resetting password issue after the new update 
Issue Description: After resetting the password, the app keeps asking me to enter the new password and not accepting it. Also, sharing is not working, due to incorrect password “as per the displayed popup”. Moreover, after entering the password and getting rejected, i get a popup message saying that i have exceeded the allowed incorrect password attempts and asking me to try again in 10 mins. I have tried uninstalling the app and reinstalling it again, the issue was fixed for a couple minutes and its failing again. Steps to Reproduce: 1- Reset the password of the profile you’re currently using 2- Try to navigate to sharing page from the dexcom g5 app 3- Observe that the sharing is stopped. However, the internet connection is working fine
 
Buggy and pretty frustrating 
While I like the idea of getting my CGM data on my phone, the latest update has made this app pretty useless. Specifically: 1. Your phone is on silent but the app will give you an alert at maximum volume. But only sometimes. And when you're in the middle of a meeting or some other embarrassing situation. 2. Won't alert at all when phone is on "Do not disturb" 3. The Scheduled Alerts function just doesn't work. 4. Randomly mutes any audio activity you may be doing. Not for an alert. Just because. I can't trust this thing with my life.
 
Sound issues 
Your latest update causes periodic drops in audio when listening to a podcast or music. Depending on mute switch setting it either reduces the sound level of the music (if mute is off) or silences it altogether (if mute is on). In both cases, music is restored to normal after about 5-10 seconds. This happens when Dexcom is in the background.
 
Frustrated 
The Dexcom app is interfering with my iPhone's audio. When the problem could not be resolved, I turned in my 6 plus for an 8 plus. I have had the new phone 2 days and the problem is back. I think I might have to go back to carrying the Dexcom receiver, which is just unacceptable. Also, when the app requires me to enter my blood sugar, the "Submit" button isn't always visible. I'm just about ready to give it all up😒.
 
Can't enter BG value 
I can't calibrate because there's no "okay" button when trying to calibrate my BG. I have everything updated and it worked for a few days and then the button disappeared again. Very annoying. Just include the enter button on the keyboard!!
 
Appreciate the new schedule feature for alarms 
In general dexcom works great. I wouldn’t want to go without it. The recently added schedule for alarms and the ability to silence or allow the alarm to go with the phone volume is very helpful. I have it set to follow my phone volume during the day at work and have a schedule for override when I am home and at night. This flexibility is very useful. Would love to be able to dismiss alarms through watch.
 
Sound issues 
I’m also having issues with the sound on my phone since the most recent update. When listening to podcasts, pandora, or iTunes there is a change in volume. Podcasts have paused and I believe that’s happening when Dexcom is pulling data. When I open Dexcom app while listening to audio the audio stops. This was not an issue before the most recent update.
 
New update is awful 
The app was good before the update. Now, half of the time I can't enter my blood sugar because the keyboard blocks the save button. I had to power cycle my phone twice before it finally worked. Also, if I'm doing anything on Bluetooth it turns the volume down every few minutes when it's doing its checks. I also don't understand why on the follow app you can see data for up to 24 hours and on this app you see 3 hours and that's it. Not a fan at all.
 
Latest update sending audio interrupts unnecessarily 
First, want to state that I love the app in general. Definitely room for improvement, but after getting the G5 in Nov of 2017 (my first CGM) my A1c went from 6.3 to 5.4, which is entirely the result of the convenience of having my blood glucose data available on my phone, and the AGP from clarity reports. Both are game changers to how I manage my diabetes. Could never go back to finger sticks to monitor my glucose levels. However, the latest update to Dexcom app sends an audio interrupt any time the app is poling the transmitter for data. For instance, if listening to a podcast every 5 minutes the podcast audio will be paused for 5-10 seconds while the app gets the latest reading from the transmitter. Also have intermediate issues with volume being lowered while listening to audio on other apps (music, podcasts, etc) when Dexcom app is active. Also, audio is paused anytime I bring up Dexcom app to check readings. Happens on 6s plus. Have issue with both Bluetooth headphones (AirPods) and when connected to 3.5mm out. Per the opening, the system/app has significantly improved my diabetes care, and I NEED to have that info available at all times. However, our smartphones are multifunction devices, and having this app significantly degrade using audio in ANY other app is terrible. It’s at the point where I am considering syncing the transmitter to the receiver that comes with the kit, which would entail hauling around another device everywhere, which is not appealing for obvious reasons. Please fix, very annoying!
 
Not keeping up 
Absolutely love this technology. However, the developers for this app are not keeping up with the software updates from Apple. Since updating to the very newest version of iOS I lose my signal more than I have it through my iPhone. I know this is an issue with the app sense my separate receiver has no problems connecting and staying connected to my transmitter. You guys can do much, much better. If you hope to be the amazing medical technology for us diabetics that you want to be, you need to get some people involved in this project that can work and keep up with the updates. This can’t be a “hit and miss” kind of technology. I just woke up this morning again to see that I had lost signal overnight for no apparent reason. That’s a huge health risk in my world. Come on guys… You can do better.
 
GBoard Issue 
When entering blood glucose logs using Google’s GBoard, the ‘save’ button doesn’t adjust up above the keyboard to allow me to complete the log. I have to subsequently delete my GBoard every time I enter a BG, which is frustrating. Hope to see this fixed in the next update. Thanks!
 
Update isn't work! 
UPDATE: Right now it won't work correctly, and even after turning off all alerts (besides the urgent low which you can't turn off) and it keeps beeping at me, and my glucose is 120, I'm really frustrated. These are only audible through a Bluetooth connection, you hear nothing unless it's connected to my speaker or headphones. I So the new update introduced a couple nice features, but it is causing my Bluetooth streaming music to have constant interruption. Beeps when it's silenced, mutes my music even if no alert should be sounding, and adjusts my volume. I have also had issues where the 'enter' and 'cancel' buttons are not visible on occasion. This has cost me 6 extra finger sticks this week alone. The buttons end up coming back but only later when the glucose value is no longer valuable. The old app was better, and if I could switch back I would. The new functionality isn't worth these hassle.
 
Interrupting my music/audio 
There’s a weird bug that’s causing the volume of my music to lower for a few seconds. I suppose this happens when the app is gathering data. It seems I am not the only person with this issue.
 
Love the app, new update has issues 
This is the most used app I have. I absolutely love the technology. The most recent update is causing issues when I stream music on my phone. I travel extensively for work and spend the majority of my time in my car and any time I check my blood sugar values on the app (I keep the app running while driving along with my Amazon Prime music and Google Maps) I lose all audio. Please be aware that the new update is doing this.
 
Unable to enter by meter value 
Unable to enter by meter value
 
Some issues 
The app takes over the sound on my iPhone when it's open.
 
You broke it. 
Horrible update. I can no longer calibrate my sensor because the green enter button no longer appears on the calibration screen. For the love of God, please roll back this update until you fix the problem.
 
Unable to enter BG values👎🏼 
Update 2/26: the inability to enter BG values continues....since I'm not able to calibrate, I have had many inaccurate readings from my CGM that have caused issues. Please fix asap! Dexcom 1.7.5/iPhone X -----------------------------— Update: after rebooting my iPhone several times and reinstalling the app, I can enter BG values again. Also glad that alarms can be silenced now! _____________________ I love my G5 but after the latest app update (1.7.5) - I'm not able to enter glucometer readings since the submit/enter button is gone. Hope you fix this ASAP since it's worthless without the ability to calibrate!!
 
BAD Update; Don’t if you haven’t yet! 
If you haven’t updated to version 1.75, don’t. That is unless you don’t use your phone to listen to audio or any sort - at least on iOS. Normally when you get a notification on an iPhone, the OS will compress the sound of whatever audio you’re listening to (music, YouTube videos, etc.) for 2-5 seconds, and this is referred to as “ducking”. After this update, the Dexcom App will cause ducking intermittently even when there’s no notification. I don’t use the app’s sounds as it is since vibrate works fine for me. Since Dexcom only releases updates every 2-3 months, I deleted this version, and reverted to version 1.71 using the backup I created in iTunes (on my computer) last month. This definitely needs to be fixed FAST. I can’t believe they released this update without noticing this 👎
 
Awesome cgm, terrible app update 
I loved the Dexcom cgm and app, but the update has made me unable to to calibrate. It lets you enter your bg, but you can not hit "okay". You also can not exit the calibration screen without closing the entire app. Also, when using Bluetooth audio, it randomly cuts out every few minutes. This needs to be fixed ASAP... The calibration issue is dangerous. Let us go back to the older version. This new one is really disrupting things!!
 
SCREEN BLOCKED- Can't Enter BGs!!!! 
Since updating I am unable to consistently enter blood sugar calibrations. The SAVE button either doesn't appear or is blocked by the keyboard on the enter blood sugar screen. This renders the app useless, as I am unable to enter calibrations! PLEASE FIX - I have emailed technical support twice! And have yet to hear back from Dexcom at all.
 
Seriously? 
For a product that’s changing the medical playing field why is this app such a piece of garbage? For a product that is raking in massive amounts of cash why can’t you hire a team to fix all the glitches that literally EVERYONE is complaining about??
 
Messes with Volume 
The new app causes the volume on the phone to reduce for a few seconds randomly while listening to music. It’s beyond annoying. It will also completely reduce the volume if you are in the app itself.
 
Needs fixed!! 
When are you gonna fix this app!! Can't enter a calibration BGL most of the time!!!
 
New update 
Like using this app. However planning on deleting it if the music doesn’t get fixed. I can listen to any music apps without it randomly turning down then going back up. Only started after this Dexcom update.... please fix ASAP!!!!!!
 
Would annotation feature 
Just started with this works well, although can only pair with one smart device at a time. but with iPhone works well. only thing I can think of would make it better is ability to annotate the log/graph of bs measurements over time, so could more easily look back and see bs rise/fall following food or injection
 
Nope. Doesn't calibrate reliably. 
Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Volume control issues 
I’m also having volume control issues with the most recent update. Please fix this issue Dexcom!!
 
A terrible app for a great device 
I'm going to leave the dexcom hardware out of this. I love the dexcom hardware. The app however is a different story. Updates are, at best, slow moving. Most companies are able to release weekly or even more frequent updates but Dexcom's updates are close to every six months. They severely lag behind ape updates which can cause bugs and issues. Dexcom's claim that apple is slowing down their updates is crazy. They need to hire significantly better software developers if they're struggling this badly to keep up. The most recent issue with the app is that after their update, you can no longer use third party keyboards and your dexcom app at the same time. Most company's response would be to apologize and prioritize a quick patch update that solves the issue. Not Dexcom. "We know this is an issue, it may or may not be fixed.". Given their usual timeline I would expect that if their is a resolution it will take six months or longer. It's a shame to see such an amazing device be held back by a very poor software team. Due to their unwillingness to be responsive and efficient, I'd say 1 star is fair. If they start to address issues more rapidly and are more transparent with customers about fixes, I will adjust my review accordingly.
 
What is up with this buggy app 
Why are the open source apps so much better? I don't have a button to submit my calibration after the two hour warm up.
 
Audio issues with the latest update 
As others have noted, the latest update causes incredibly annoying audio interruptions when triggering notifications. When playing audio via Bluetooth, the moment any notification from the Dexcom app is received the audio (at least from the Podcasts app) pauses and then resumes about ten seconds later. Apps playing audio that do not pause (YouTube, or the Music player) instead have their volume nearly muted for that time span. This is an extreme oversight by the developers, and makes using the Dexcom CGM, which is otherwise fantastic, incredibly annoying. Please fix this quickly, before I'm tempted to just kill the app every time I get in the car so I can enjoy listening to podcasts during my commute!
 
Bluetooth listening interrupted 
Like the previous reviewer, my Bluetooth podcast listening is interrupted by this app and the latest update. Every 5 minutes the audio stream pauses for 6 seconds, then resumes. This behavior started when I updated this app. I tried removing the app and the interruptions stopped. The behavior is fairly well-behaved in that the audio stream usually starts up by itself, but it’s a bit annoying to have it keep pausing. Is there some way to fix this? Or is it a factor of IOS Bluetooth & sharing with another app?
 
Works well; Improved alert options 
Love the sensor and now the app. The February ‘18 release fixes the lack of alert options. Update to review after using for a week: Switching to the Dexcom app mutes any sounds already playing, such as streaming audio. It shouldn’t. The alternate schedule doesn’t turn off the alert sounds. Maybe some better help to clarify in case I don’t understand how to use it. The silent mode button does turn off the alerts. Good.
 
Better bit some bugs 
I love the new update. I’ve been waiting for something like this and I am happy with the idea. More schedules? Maybe? I’m just happy with more than one so far. But I hope you fix the sound issue soon. If I open the app to acknowledge an alarm, all music stops. Small bug. I hope you are working on it and update with a fix soon.
 
Sigh 
So when I try to update my blood sugar I'm sent to a screen without a back or submit button. So a useless dead end. The alert schedule feature is confusing and doesn't appear to work (I updated my non scheduled alerts to give me hypo alerts at 90 and all the sudden even though I was in the scheduled window as indicated by the alert icon on main screen, I was getting hypo alerts at 90 - scheduled alerts have hypos at 80.) Should be able to define multiple time windows. Should be able to edit those settings easily. Should not see all those settings on one page, nest the full details yo. Should be able to manually start a mode (movie theater. Class. Whatever). Also design is still, sorry to say it, so ugly. Push harder! Your hardwear is the best, shouldn't your software be too?
 
Can't CALIBRATE! FIX THIS!!' 
We can't CALIBRATE because the acreen's Save button gets covered by the keyboard. This destroys the utility of an incredibly expensive product. Fix this.
 
Great device, terrible update 
Like other reviewers here, I too am having audio problems on my phone with this update. Volume lowers then rises, the sound of typing rises and falls and now other even video volume is being affected. Please fix this issue!
 
Lazy Design with tons of bugs 
There’s clearly no QA that goes into the design of this app as we get pushed out rate updates that seem to actually make the app less functional (the most recent one reminding me I have diabetes every 5 seconds by spontaneously lowering my music) Dexcom should start hiring diabetics to design their apps so it gets actual effort put into it. Alarms are annoying and cannot be disabled in many cases. You can only set limited alert thresholds so if you want to know your blood sugar but don’t want to have an alarm screaming in your ear you’re tough out of luck. I wish the team developing this put half as much effort as I do trying to stay alive every day.
 
How much was this last release tested? 
SOLID app until this last release. I have read some of the other issues people are experiencing. My issue is that if I am listening to anything on my phone and I open the app, it pauses the audio. Many times I don’t even have to open the app (running in background with phone locked) and it will just randomly pause whatever is playing whether it is music or an audiobook. Until it is fixed I will just keep my finger ready to hit the play button many times as my music and audiobooks are paused. And yes, I have already worked with support and the only provided solution was to uninstall the app, reboot my phone, and reinstall it. Doing this three times did not resolve the issue. Also, this is another attempt at what seems like a pretty straightforward feature request. I am not always in a position to calibrate when the 12 hour calibration alert appears. It would make sense to be able to select “remind me in 30 min”, “remind me in 1 hr”, etc. Instead you just get alerted every five or so minutes.
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c.

You can’t calibrate with a 3rd party keyboard like Gboard installed. I have to literally force close the app, delete the keyboard and try again. How does that make it through testing? This is 0 star worthy if I could even select that.

Useless now 
With the latest update I am no longer able to enter my blood sugars to calibrate my cgm. The keyboard now covers the green save button. This renders my cgm useless and this is extremely frustrating and frightening since this is a medical device used to keep me from having diabetic seizures.
 
Horrible 
New update is horrible. I've emailed them and nobody is fixing it. Every time I want to calibrate I have to delete the app and redownload it. So annoying.
 
Problem entering calibration BG's 
So I've changed my sensor twice now since the latest update and continue to have this problem: When I tap the green circle to enter my BG the Save button doesn't travel up on the screen. It remains near the bottom, under the key pad or doesn't appear at all. So I can't enter a BG. And the only way to get back to the main screen (not that there's any point, really) is to hard closer the Dexcom app and reopen it. But the problem remains. I've gone am entire day this time without an inexplicable self-fix that usually happens with this glitch. This is not the first time I've had trouble with the keypad getting glitchy on this app. But it seems to be a consistent issue with this update. Any suggestions to fix this? Bare in mind I've already tried closing the app and reopening it AND restarting my iPhone 7 with no success to solve the problem.
 
Won't let me calibrate 
Newest app update won't let me calibrate. App unusable if changing sensors since the keyboard is blocking the save calibration button. Might be time to start looking into Medtronics system since I can't get through to dexcom on the phone/social media/email. Nothing
 
Calibration 
Newest update won't let me calibrate, have to delete and re download app every 6 hours.
 
Latest Update Crashes Constantly 
My App keeps crashing and I’m not sure if it’s when my iPhone is updating apps. Occasionally this happens while I’m asleep so you can imagine the frustration of waking up to an extreme Hypo or Hyper BG. I’ve been trying to problem solve by turning off my Bluetooth, reinstalling the app and reconnecting the Bluetooth. I’ve also turned off my automatic updates, but none of those actions seem to make a difference. Sometimes during the day when I’m using another app it gives me a Lost Signal notification and my Share recipients worry about me and start calling me. This has turned into a huge problem so now I have a backup receiver that doesn’t make an audio sound as loud as I need (like the one on my phone) to wake up.
 
Love the iPhone X Support - BT Audio Issues 
I was very excited with the new update to the G5 app as it finally brought support for the iPhone X screen size. The app works well as far as pulling in BGs from the transmitter. I do still sometimes get Signal Loss, but thanks to the newer transmitters it backfills once it reconnects. My big bummer though right now is the audio from my iPhone pauses if you open the app. This seems to happen with any audio The other big one is outputting to Bluetooth audio devices like my AirPods or my speaker at home. Every 5 or 10 minutes the audio will pause for a few seconds. It comes back, but it’s an annoying disturbance in listening to music or podcasts. Hope Dexcom can fix it soon. Oh also don’t use Third Party keyboards when you try and calibrate because they’ll cause the Save button to disappear and you have to quit the app, change your keyboard and relaunch it.
 
Sound issues 
I’m also having issues with the sound on my phone since the most recent update. When listening to podcasts, pandora, or iTunes there is a change in volume. Podcasts have paused and I believe that’s happening when Dexcom is pulling data. When I open Dexcom app while listening to audio the audio stops. This was not an issue before the most recent update.
 
New update is awful 
The app was good before the update. Now, half of the time I can't enter my blood sugar because the keyboard blocks the save button. I had to power cycle my phone twice before it finally worked. Also, if I'm doing anything on Bluetooth it turns the volume down every few minutes when it's doing its checks. I also don't understand why on the follow app you can see data for up to 24 hours and on this app you see 3 hours and that's it. Not a fan at all.
 
Latest update sending audio interrupts unnecessarily 
First, want to state that I love the app in general. Definitely room for improvement, but after getting the G5 in Nov of 2017 (my first CGM) my A1c went from 6.3 to 5.4, which is entirely the result of the convenience of having my blood glucose data available on my phone, and the AGP from clarity reports. Both are game changers to how I manage my diabetes. Could never go back to finger sticks to monitor my glucose levels. However, the latest update to Dexcom app sends an audio interrupt any time the app is poling the transmitter for data. For instance, if listening to a podcast every 5 minutes the podcast audio will be paused for 5-10 seconds while the app gets the latest reading from the transmitter. Also have intermediate issues with volume being lowered while listening to audio on other apps (music, podcasts, etc) when Dexcom app is active. Also, audio is paused anytime I bring up Dexcom app to check readings. Happens on 6s plus. Have issue with both Bluetooth headphones (AirPods) and when connected to 3.5mm out. Per the opening, the system/app has significantly improved my diabetes care, and I NEED to have that info available at all times. However, our smartphones are multifunction devices, and having this app significantly degrade using audio in ANY other app is terrible. It’s at the point where I am considering syncing the transmitter to the receiver that comes with the kit, which would entail hauling around another device everywhere, which is not appealing for obvious reasons. Please fix, very annoying!
 
Not keeping up 
Absolutely love this technology. However, the developers for this app are not keeping up with the software updates from Apple. Since updating to the very newest version of iOS I lose my signal more than I have it through my iPhone. I know this is an issue with the app sense my separate receiver has no problems connecting and staying connected to my transmitter. You guys can do much, much better. If you hope to be the amazing medical technology for us diabetics that you want to be, you need to get some people involved in this project that can work and keep up with the updates. This can’t be a “hit and miss” kind of technology. I just woke up this morning again to see that I had lost signal overnight for no apparent reason. That’s a huge health risk in my world. Come on guys… You can do better.
 
GBoard Issue 
When entering blood glucose logs using Google’s GBoard, the ‘save’ button doesn’t adjust up above the keyboard to allow me to complete the log. I have to subsequently delete my GBoard every time I enter a BG, which is frustrating. Hope to see this fixed in the next update. Thanks!
 
Update isn't work! 
UPDATE: Right now it won't work correctly, and even after turning off all alerts (besides the urgent low which you can't turn off) and it keeps beeping at me, and my glucose is 120, I'm really frustrated. These are only audible through a Bluetooth connection, you hear nothing unless it's connected to my speaker or headphones. I So the new update introduced a couple nice features, but it is causing my Bluetooth streaming music to have constant interruption. Beeps when it's silenced, mutes my music even if no alert should be sounding, and adjusts my volume. I have also had issues where the 'enter' and 'cancel' buttons are not visible on occasion. This has cost me 6 extra finger sticks this week alone. The buttons end up coming back but only later when the glucose value is no longer valuable. The old app was better, and if I could switch back I would. The new functionality isn't worth these hassle.
 
Interrupting my music/audio 
There’s a weird bug that’s causing the volume of my music to lower for a few seconds. I suppose this happens when the app is gathering data. It seems I am not the only person with this issue.
 
Love the app, new update has issues 
This is the most used app I have. I absolutely love the technology. The most recent update is causing issues when I stream music on my phone. I travel extensively for work and spend the majority of my time in my car and any time I check my blood sugar values on the app (I keep the app running while driving along with my Amazon Prime music and Google Maps) I lose all audio. Please be aware that the new update is doing this.
 
Unable to enter by meter value 
Unable to enter by meter value
 
Some issues 
The app takes over the sound on my iPhone when it's open.
 
You broke it. 
Horrible update. I can no longer calibrate my sensor because the green enter button no longer appears on the calibration screen. For the love of God, please roll back this update until you fix the problem.
 
Unable to enter BG values👎🏼 
Update 2/26: the inability to enter BG values continues....since I'm not able to calibrate, I have had many inaccurate readings from my CGM that have caused issues. Please fix asap! Dexcom 1.7.5/iPhone X -----------------------------— Update: after rebooting my iPhone several times and reinstalling the app, I can enter BG values again. Also glad that alarms can be silenced now! _____________________ I love my G5 but after the latest app update (1.7.5) - I'm not able to enter glucometer readings since the submit/enter button is gone. Hope you fix this ASAP since it's worthless without the ability to calibrate!!
 
BAD Update; Don’t if you haven’t yet! 
If you haven’t updated to version 1.75, don’t. That is unless you don’t use your phone to listen to audio or any sort - at least on iOS. Normally when you get a notification on an iPhone, the OS will compress the sound of whatever audio you’re listening to (music, YouTube videos, etc.) for 2-5 seconds, and this is referred to as “ducking”. After this update, the Dexcom App will cause ducking intermittently even when there’s no notification. I don’t use the app’s sounds as it is since vibrate works fine for me. Since Dexcom only releases updates every 2-3 months, I deleted this version, and reverted to version 1.71 using the backup I created in iTunes (on my computer) last month. This definitely needs to be fixed FAST. I can’t believe they released this update without noticing this 👎
 
Awesome cgm, terrible app update 
I loved the Dexcom cgm and app, but the update has made me unable to to calibrate. It lets you enter your bg, but you can not hit "okay". You also can not exit the calibration screen without closing the entire app. Also, when using Bluetooth audio, it randomly cuts out every few minutes. This needs to be fixed ASAP... The calibration issue is dangerous. Let us go back to the older version. This new one is really disrupting things!!
 
SCREEN BLOCKED- Can't Enter BGs!!!! 
Since updating I am unable to consistently enter blood sugar calibrations. The SAVE button either doesn't appear or is blocked by the keyboard on the enter blood sugar screen. This renders the app useless, as I am unable to enter calibrations! PLEASE FIX - I have emailed technical support twice! And have yet to hear back from Dexcom at all.
 
Seriously? 
For a product that’s changing the medical playing field why is this app such a piece of garbage? For a product that is raking in massive amounts of cash why can’t you hire a team to fix all the glitches that literally EVERYONE is complaining about??
 
Messes with Volume 
The new app causes the volume on the phone to reduce for a few seconds randomly while listening to music. It’s beyond annoying. It will also completely reduce the volume if you are in the app itself.
 
Needs fixed!! 
When are you gonna fix this app!! Can't enter a calibration BGL most of the time!!!
 
New update 
Like using this app. However planning on deleting it if the music doesn’t get fixed. I can listen to any music apps without it randomly turning down then going back up. Only started after this Dexcom update.... please fix ASAP!!!!!!
 
Would annotation feature 
Just started with this works well, although can only pair with one smart device at a time. but with iPhone works well. only thing I can think of would make it better is ability to annotate the log/graph of bs measurements over time, so could more easily look back and see bs rise/fall following food or injection
 
Nope. Doesn't calibrate reliably. 
Prior version was rock solid. On my X this often refuses to accept a requested calibration. You can type the number, but the DONE button may not be present. Or, maybe it will. Or not. If no DONE then It also ignores calibrations done early. Do one at 11 hours? It will harass you for one an hour later. This version goes backwards, and I would revert to the prior release if I could.
 
Fix the sound issue and stop ruining Spotify 
I cannot be having the volume to my Spotify go down every five minutes. Next time you update the app (which better be soon or I’m gonna stop using my sensor) you need to actually test it before pushing it out to everyone. I pay WAY TOO MUCH for Dexcom prescriptions to be having this issue.
 
Volume control issues 
I’m also having volume control issues with the most recent update. Please fix this issue Dexcom!!
 
A terrible app for a great device 
I'm going to leave the dexcom hardware out of this. I love the dexcom hardware. The app however is a different story. Updates are, at best, slow moving. Most companies are able to release weekly or even more frequent updates but Dexcom's updates are close to every six months. They severely lag behind ape updates which can cause bugs and issues. Dexcom's claim that apple is slowing down their updates is crazy. They need to hire significantly better software developers if they're struggling this badly to keep up. The most recent issue with the app is that after their update, you can no longer use third party keyboards and your dexcom app at the same time. Most company's response would be to apologize and prioritize a quick patch update that solves the issue. Not Dexcom. "We know this is an issue, it may or may not be fixed.". Given their usual timeline I would expect that if their is a resolution it will take six months or longer. It's a shame to see such an amazing device be held back by a very poor software team. Due to their unwillingness to be responsive and efficient, I'd say 1 star is fair. If they start to address issues more rapidly and are more transparent with customers about fixes, I will adjust my review accordingly.
 
What is up with this buggy app 
Why are the open source apps so much better? I don't have a button to submit my calibration after the two hour warm up.
 
Audio issues with the latest update 
As others have noted, the latest update causes incredibly annoying audio interruptions when triggering notifications. When playing audio via Bluetooth, the moment any notification from the Dexcom app is received the audio (at least from the Podcasts app) pauses and then resumes about ten seconds later. Apps playing audio that do not pause (YouTube, or the Music player) instead have their volume nearly muted for that time span. This is an extreme oversight by the developers, and makes using the Dexcom CGM, which is otherwise fantastic, incredibly annoying. Please fix this quickly, before I'm tempted to just kill the app every time I get in the car so I can enjoy listening to podcasts during my commute!
 
Bluetooth listening interrupted 
Like the previous reviewer, my Bluetooth podcast listening is interrupted by this app and the latest update. Every 5 minutes the audio stream pauses for 6 seconds, then resumes. This behavior started when I updated this app. I tried removing the app and the interruptions stopped. The behavior is fairly well-behaved in that the audio stream usually starts up by itself, but it’s a bit annoying to have it keep pausing. Is there some way to fix this? Or is it a factor of IOS Bluetooth & sharing with another app?
 
Works well; Improved alert options 
Love the sensor and now the app. The February ‘18 release fixes the lack of alert options. Update to review after using for a week: Switching to the Dexcom app mutes any sounds already playing, such as streaming audio. It shouldn’t. The alternate schedule doesn’t turn off the alert sounds. Maybe some better help to clarify in case I don’t understand how to use it. The silent mode button does turn off the alerts. Good.
 
Better bit some bugs 
I love the new update. I’ve been waiting for something like this and I am happy with the idea. More schedules? Maybe? I’m just happy with more than one so far. But I hope you fix the sound issue soon. If I open the app to acknowledge an alarm, all music stops. Small bug. I hope you are working on it and update with a fix soon.
 
Sigh 
So when I try to update my blood sugar I'm sent to a screen without a back or submit button. So a useless dead end. The alert schedule feature is confusing and doesn't appear to work (I updated my non scheduled alerts to give me hypo alerts at 90 and all the sudden even though I was in the scheduled window as indicated by the alert icon on main screen, I was getting hypo alerts at 90 - scheduled alerts have hypos at 80.) Should be able to define multiple time windows. Should be able to edit those settings easily. Should not see all those settings on one page, nest the full details yo. Should be able to manually start a mode (movie theater. Class. Whatever). Also design is still, sorry to say it, so ugly. Push harder! Your hardwear is the best, shouldn't your software be too?
 
Can't CALIBRATE! FIX THIS!!' 
We can't CALIBRATE because the acreen's Save button gets covered by the keyboard. This destroys the utility of an incredibly expensive product. Fix this.
 
Great device, terrible update 
Like other reviewers here, I too am having audio problems on my phone with this update. Volume lowers then rises, the sound of typing rises and falls and now other even video volume is being affected. Please fix this issue!
 
Lazy Design with tons of bugs 
There’s clearly no QA that goes into the design of this app as we get pushed out rate updates that seem to actually make the app less functional (the most recent one reminding me I have diabetes every 5 seconds by spontaneously lowering my music) Dexcom should start hiring diabetics to design their apps so it gets actual effort put into it. Alarms are annoying and cannot be disabled in many cases. You can only set limited alert thresholds so if you want to know your blood sugar but don’t want to have an alarm screaming in your ear you’re tough out of luck. I wish the team developing this put half as much effort as I do trying to stay alive every day.
 
How much was this last release tested? 
SOLID app until this last release. I have read some of the other issues people are experiencing. My issue is that if I am listening to anything on my phone and I open the app, it pauses the audio. Many times I don’t even have to open the app (running in background with phone locked) and it will just randomly pause whatever is playing whether it is music or an audiobook. Until it is fixed I will just keep my finger ready to hit the play button many times as my music and audiobooks are paused. And yes, I have already worked with support and the only provided solution was to uninstall the app, reboot my phone, and reinstall it. Doing this three times did not resolve the issue. Also, this is another attempt at what seems like a pretty straightforward feature request. I am not always in a position to calibrate when the 12 hour calibration alert appears. It would make sense to be able to select “remind me in 30 min”, “remind me in 1 hr”, etc. Instead you just get alerted every five or so minutes.
 
Alters Volume in Other Apps - UPDATE 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness. UPDATE 3/2/18: The volume changing issue hasn’t occurred for nearly a week, and Dexcom support did respond, so changing my rating accordingly. FEATURE NEEDED: Please add a feature wherein the app takes all of the results from the last 90 days and averages them out so that we can have an ESTIMATED A1c.
 
Loses connectivity 
Constantly loses connection.
 
Can't add Blood Sugars most of the time 
Most of the time, when you go to enter a blood sugar, you are not able to collapse the number entry which is blocking the save option. This should have been pointed out in the development process ASAP.
 
User should have the choice on alarms 
The sensor is great. The app is not. Super annoying that the app pauses music and podcasts now when it opens up. The app also should not override do not disturb mode when trying to get a first blood sugar. That’s not a time sensitive/emergent step like urgent low glucose.
 
Apple Watch app needs improvement. 
I like the app. It’s not very customizable and there isn’t any data aside from your current number. But it works well. The Apple Watch app, however, could use some major improvement. First of all, it doesn’t actually update on my watch face. Half the time it’s just a line and the other half of the time it is an old number. I have to touch it to open the app to get an updated number. Defeats the purpose of having it on my watch. Another thing is that I can’t silence alarms from my watch! I have to get up and get my phone or dog it out of my purse to shut the alarm off. Extremely inconvenient.
 
App does not work on iPhone X. 
Save button is hidden when trying to enter blood sugar in app. App is unusable on this device. Dexcom tech support was contacted prior to posting this review. A response has not been received.
 
Sharing is Confusing 
The website says you can now share from the app, but I see no way to do that.
 
Music Interference 
I too am experiencing interference from the Dexcom app when playing music. Very annoying and needs to be fixed ASAP. And maybe consider testing a bit more before releasing updates. I know that sounds kind of snarky but come on, testing interaction with common Bluetooth apps seems like a no brainer. Also would like to have full control over alerts. The low alert at 55 is way too high for me. Maybe that’s a good spot for others? Here again I just want control over it. Otherwise this is a fantastic product. It checks 9 out 10 boxes. Well maybe 8 out of 10 with the music issue.
 
Won't let me calibrate. 
This morning as I attempted to calibrate, the screen offered no enter, submit or return button. I have to close the app to see my glucose levels and remain unable to calibrate. This app was better when it first came out.
 
No way to press Enter to enter BG meter values in lastest version on iPad 
Edited February 17, 2018 to change the reading from 1 to 5 after the error in coding was corrected. I can now enter calibration numbers. ................................ Feb. 16, 2018 I've used this a lot. But when I went to enter the calibration values this morning I could key in the numbers but there was no Enter or Save to press. The keypad is covering them up and I can't get rid of it. Please get rid of the app keypad so that I can minimize the regular one and get to the Save button. Currently I cannot calibrate my new sensor!
 
Audio pausing 
With the latest update, I have notice audio pauses every 5 minutes for seconds while listening to Audible or Podcast.
 
Does great things when functional. 
I have not heard anything after reporting this issue to Dexcom, so I will post my findings and workaround here. There is a critical issue in Dexcom G5 Mobile Version 1.7.5 on iOS11.2.5 that prevents users from entering glucose readings / numbers into the app. Once you type the number, you cannot collapse the numpad (There should be save and cancel buttons). You also cannot hit enter on an attached physical keyboard to have the value accepted. The only workaround I have found, is to install a second software keyboard, while the Enter BG Meter Value screen is up, and delete the keyboard in use. This forces the numpad menu to go away and sometimes renders the Save/Cancel buttons. This is not what I consider acceptable functionality for a critical use case application. Not being able to confirm results with a paired, physical keyboard is an anti pattern that's exasperates the ui bug present in 1.7.5.
 
Newest Update is Horrible 
I can't calibrate since the newest update. The keypad goes over the enter button and can't be minimized. May look to the new monitor by Freestyle
 
Please fix 
The new update keeps glitching and I can't calibrate my sensor!! I NEED TO CALIBRATE TO KEEP MY NUMBERS ON POINT. Come on dexcom, you're better than this.
 
Latest Update Has Severe Bugs 
Have used Dexcom app for over year with zero issues, but latest update (while including some welcome upgrades) has severe bugs that prevent calibration and thus make app useless once your sensor requires updating. Over past three days I have twice tried to calibrate and have been prevented from doing so because the "Save" button never appears to confirm the input blood sugar reading. Coupled with a required sensor replacement this effectively makes the app useless. I have tried closing / rebooting app, and restarting iphone with no success. Sometimes the save button *does* appear...but this is perhaps 5% of the time i click the "Calibrate" icon.
 
Love this APP but..... As is it's useless 
Iol give it a 5 as soon as this is fixed. Been using Dexy for 5 + years. They recently did an update to allow accrediting alarms, etc but now I'm unable to calibrate because I can submit the BG #. The keypad won't go away, covering the submit button.
 
Buggy 
Sometimes The ok button is missing on the BG entry screen
 
Weird Volume Bug 
This newest update 1.7.5 is causing my iPhone 7 to randomly lower the volume while playing music, etc. This happens about every 3-5 mins and lasts about 5 seconds, after which the volume goes back up. This issue goes away when I close the app. Very annoying. Otherwise a pretty good app.
 
New update works great except 
If I’m playing music and I enter the app, my music stops. Frustrating at the gym.
 
I can no longer enter my blood sugar! 
At a minimum my cgm wants me to enter in my blood sugar twice a day that is obtained from a traditional glucose monitor and enter it to true up the accuracy. All of a sudden, the enter button is missing and I can no longer enter my blood sugar!!! This is a very big deal and imperative to the function of the monitor!! Please fix this!
 
New update is not awful anymore! 
Thank you so much for fixing the app! Now I don’t have to try and remember to turn on and off alerts when I don’t want my phone going off. Dexcom is once again making diabetes so much easier to manage!
 
New update problems 
Love that they implemented the idea I have them a while back and set profiles for the alerts so I can choose quieter ones while at work and the rediculously loud ones for when I actually want them to be that loud. That being said, this update made everything smaller, almost like increasing the resolution and everything got scaled down. I actually like the look but now I can't enter my calibrations. On my Gboard keyboard I can enter the numbers but the save button is missing. I switched to Apple default keyboard and the save button is back but it won't load the keyboard for me to enter my numbers. Luckily I had a Bluetooth keyboard and used that to calibrate on the keyboard that I couldn't use but the save button was there. Was this an oversight? What good is this whole thing if I can't calibrate with my blood sugar readings??
 
Bad Bug 
I always give the Dexcom app 5 stars but this latest upgrade has rendered it impossible to put in your calibration glucose number. The number pad pops up over the green save button so when you type in your glucose, you have to completely get out of the app in order for it to function at all.
 
Volume control kills it, in a bad way 
Volume is not controlled by the iPhone volume controls at all. You either have vibrate or obnoxiously loud for high warning, and ONLY obnoxiously loud for low warning. Horrible for public situations such as work, church, movie theater, etc. What were they thinking?!? You used to have normal control in older versions. Otherwise, the app seems to be slightly improved on actual reading values when compared to actual meter values, but that's probably due to sensor improvement. Agree with most everyone else - please put volume control back to the phone!
 
This app is great, but one major bug right now 
I don’t know how I lived before having this app and the CGM. That said, I recently noticed a seriously problematic bug within this app. If you’re using a custom keyboard such as Swiftkey, it’s common for the keyboard to hide/obscure the green submit/enter button on any input pages. This makes entering your glucose, your insulin amount, or even carbohydrates impossible. A temporary workaround is to tilt the phone from left to right, causing the portrait to landscape orientation to reveal the green submit button... but that only works during regular operation. Tonight, while trying to enter my first two blood sugars upon inserting a new sensor, no matter how many times I tilted the phone – I could not get the submit button to show up, therefore I couldn’t start my sensor. I ended up fixing this by going into the settings section on this app and trying to edit some field, and then forcefully resetting the keyboard to the regular iOS keyboard from there. I first tried doing this inside the iOS Settings app, but it made no difference, as you must change the active keyboard inside this app. Fortunately I fixed the issue, but it definitely gave me a scare.
 
Buggy app with slow development 
Recent Dexcom app update is having 2 major issues. The first is whenever music is playing (ex in my car via Bluetooth) in the background every 5 or so minutes the audio volume will decrease for several seconds and then increase again. Problem two is whenever music is playing, if I open the Dexcom app the audio will fade down in volume and actually pause. I have replicated this using Apple Music and Spotify. I have deleted and re-installed the app already and no solution. I also reset notifications to see if that would fix it and it has not. There are other users also posting this on Reddit so it is not just isolated to me. Please fix this Dexcom devs.
 
Signal loss + interruptions 
This latest version is buggy. I keep losing the signal to my phone and/or am getting the "???" It's a new sensor and I'm not taking Tylenol. Thankfully I use a T:Slim X2 and can still see the numbers on my pump. Also, annoyingly, this update causes podcasts to stop playing at 4 minute intervals. It usually takes about 3 tries to get them to start playing again, only for them to cease once more several minutes later. It will also stop playing when switching over to the dexcom app. Come on, I'd love to be able to use the app and listen to my stuff without interruption. Wicked lame.
 
Alters Volume in Other Apps 
Ever since the alert update last week, my music will lower in volume in 5-minute intervals like when an alarm would sound, but now it just does it all the time, even without any alarms. It will stop audiobooks, and dim or stop the sound in games too. The effect lasts about ten seconds and is annoying as hell. Every time it does it when I’m driving and using CarPlay I think a call is coming in. Nope, just Dexcom pretending it has an alert for me. If I shut down the app the issue stops, but then it’s yelling at me because it has lost connectivity with my transmitter repeatedly. I wish I could revert to the previous version. Hopefully this low rating will get someone’s attention. Tried the App Help and Support link but it goes to a website promoting the new Android app instead. Note: Putting the phone in vibrate, which then cancels the alerts if I disable the “Always Sound” option, also stops the issue. So there is at least something I can do when using headphones or CarPlay to stop the madness.
 
Horrible update 
After updating this app today, I can't enter blood glucose readings. I can enter the number but there is no "Enter" button. It is useless now!
 
Stops my music from playing 
I look st this app to see where I’m trending at the gym. The latest version stops my music. Please fix.
 
Can't calibrate 
It appears that the most recent version of the app doesn't play well with iOS 11.2.5, as the "save" button for calibrating is covered by the keyboard. The keyboard can't be dismissed. So you can't calibrate the app. I was able to get it calibrated by repeatedly opening and closing the app for 10-15 minutes, but when it came time to replace my sensor and do the two blood sugars it was so stubborn that I'm now calibrating on the Dexcom receiver (the hardware device the app was supposed to replace), which then calibrates the app after a few minutes. Sort of makes the app useless, though. I emailed Dexcom about it and never got a response.
 
Audio Problems 
When I disable alert sounds your application still mutes audio even though it does not play any sound while displaying notifications. This makes watching videos or listening to music very unpleasant. Can you please fix this.
 
Great features... UI needs work 
The app, along with it's sharing to other users with the app (like my wife) has been literally life saving. Love that she can " tune in," while I'm traveling for her own peace of mind, and for my added security. There is a glitch though on my phone. I use the Swype keyboard instead of the standard one... And when I have to enter a calibration, the keyboard obscures the Save button. So I need to quit the app, disable the keyboard, and relaunch to enter a calibration. Fix that glitch and you get the 5th star.
 
Disappointed in Update 
The update to 1.7.5 just came out and not only is it buggy but it’s affecting my music. Prior to the update, I could open the dexcom app, get alerts, etc without the app affecting my music. Now the app lowers my music volume if i get an alert (even when i have my alerts silenced) and stops my music completely when I open the app. If I try to calibrate, my number pad appears MAYBE 25% of the time. I couldn’t even calibrate 3 times without completely closing the app and reopening it. When I spoke with Dexcom a MONTH ago, I was told the app was ready for the update but they were waiting for apple to finish their security updates. Obviously this app wasn’t fully tested for bugs and is now turning into more of an annoyance than anything. Additionally, with the launch of the new apple watch with cellular data, dexcom is supposedly coming out with an update to link directly to the watch. Considering it took 4 months to do an update for the new iOs I can’t imagine how much longer it will take dexcom to come out with that update AND a fix for the bugs on this update. I am highly disappointed in dexcom. The only reason I’m not going back to using the standalone receiver is because I don’t want another thing I need to carry. This needs to be fixed
 
New update problems 
Loved the app up until last update. Now I can't enter BG because the key pad completely blacks out the ability to save the numbers after I have typed them in. Very frustrated!
 
Good ideas, but terrible execution since OS update 
This app used to not be so bad, but ever since my OS updated, the app has been complete trash for the following reasons: 1. It “loses signal” all the time. Essentially, the widget will show no numbers and you will receive NO ALERTS but when you open the app, your numbers magically show up (unless of course it truly says signal was lost and then if you push the “?” it will reconnect within five minutes, but why does it ever stop trying to find the signal?) 2. This is new with the latest update, but for some reason the app will now stop my music when I open the app, and randomly turn down the volume of my music every few minutes for 5-10 seconds when I’m not actively in the app. It’s almost as if it is turning down the music to give you an alert, but it has no actual alert to sound. 3. When you go to the app, your iPhone screen will turn dark for a few seconds while the app loads. Don’t get me wrong, I love my sensor! However, the app has gotten so buggy since the latest upgrade on the iPhone OS that I wouldn’t be surprised if this ends up translating into backlash from the FDA. Having your CGM 100% mobile and then allowing the app to become so unstable that people no longer receive alerts they are used to relying on is not acceptable.
 
Please fix latest release 
The buttons disappear when attempting to calibrate. Also strange button clicking loudness issue. Presently cannot calibrate using this app? Please fix this asap.
 
New update is nice but causing issue with Apple Music 
I do enjoy the most recent update. I love the idea of the schedules, please add the option to add more custom schedules. The issue i am having is since the update anytime i am listening to music using Bluetooth the audio on the music volume goes way down when it is doing its checks with the transmitter. Then after awhile when it does it again, it turns the volume back up. I tested it the last few times the audio went down, only left the Dexcom app and music open. Listened to some music for a bit the. It went down. I double clicked the home button, closed the Dexcom app and the music instantly went back up. Tested it again and it can be replicated. So somewhere in the recent update the audio Dexcom or a process causes it to lower the other audio so it can be heard but if it has nothing to signal one it just lowers it and leaves it. This seems to be a bug with this update and needs to be fixed, because i can’t keep closing the Dexcom app, i can’t keep adjusting the volume to only be surprised when it goes back up and blasts my ears out and i can’t stand it to let it just do itself every few minutes. Please fix the bug before i have to roll it back to the previous version, which i would rather deal with the out Of date version warning than blasting my ears out Thanks
 
PLEASE DOWNGRADE TO OLD APP VERSION! 
I LOVE My dexcom and I can attest that it truly saved my life a couple months ago with being able to share alerts and had fiend get EMS to house when unable to txt or call her back when BG<40mg/dL (LIFE SAVER!) the old app was amazing never really cared about adjusting alarm timing or whatever this update did. I love music and use iPhone to play music at least 2hrs but closer to 8hrs when able to. I use Bluetooth speakers in car, Alexa speaker at home friends Bluetooth speakers when there...I've never had any interruption in music playing while using dexcom in any of the above (yeah hear the alarms through speakers, but all the more motivation to correct it). NOW any time I try to open app to check BG it will stop any music or audible book playing 🤔 and was interrupting volumes when requesting to update BG. Please tell me there is a way to use old app (last months version so I can enjoy the functionality of Bluetooth for every other device) bc the biggest perks of dexcom was the fact it made me feel normal and it was SO unobtrusive and unintrusive, and felt I could enjoy life as a result but if you're going to have to interrupt one of my favorite things aka listing to music or books using my iPhone it's like a step or two backwards from such an amazing app.
 
Major bug 
In the latest version, when entering my blood glucose reading to calibrate, the keyboard covers the buttons such that I cannot enter the number and confirm it. Please fix this!
 
Please fix volume bug 
The latest update has caused my volume on my phone to turn off every time the app pushes out a update on my blood sugar. It’s very annoying. Please fix.
 
Love it, but... 
I love this new update, but ever since this update I have had a weird issue. The app softens my music whenever it gets a new BG level. I am not low or anything, it just softens my music and then turns it back up after 30 seconds. Also, whenever I listen to music and I am low or high, it takes 15 seconds after my music softens for the alarm to go off. It is a weird issue, but other than that I love the app.
 
Recent update killed clock alarm 
The recent update killed the clock alarm. The clock alarm sounds about 1 second then goes quiet ... when the dexcom app is in the foreground.
 
Latest update interrupts music 
It’s incredible how this app can get worse at time goes on. From what I can tell, this latest update triggers a silent alert EVERY TIME BLOOD GLUCOSE IS UPDATED. That means that if you’re listening to music, a podcast, audiobook, whatever, every 5 minutes the volume dips down for the “alert” (like it does when you receive a text, phone call, etc).
 
Upgraded my review 
Updated 2/21/18 The new app offers some good features as far as scheduled alerts. I am not going to complain about the inability to silence urgent alarms. I accept that. The Apple Watch interface is still broken. There is an error with background app refresh and the data will consistently be missing from complications. Work-around is the make your Watch setting to always stay on your last app, and keep the Dexcom app launched.
 
SKIP THIS LATEST UPDATE!! 
This update will break the App and (at least with an iPhone X), you will not be able to enter any manual readings... Which means you cannot enter your initial two readings and will just waste a sensor... The app is dead and broken until they release an update and fix it!!!
 
Great when it wants to be 
Most functions available. Everything you want with a Dexcom app.... Except that it loses signal much of the time (with no instructions on the way). Both my brother and I are dianetic and both reviewed this problem on two different iPhone models without losing signal on the handheld device
 
Absurd. 
For a MEDICAL device to be this unstable after MONTHS without an update is absurd. I have the latest iOS on an iPhone X and still have sporadic, unpredictable dex app crashes. Very disappointed.
 
No iPhone X! 
With the latest version (scheduling supported) it doesn’t work on the iPhone X. It pairs and then can’t connect...or it pairs and says failed sensor (has happened with 2 brand new sensors). How can this be FDA approved?? IOS 11.2.6. Previous version was a buggy mess as well...lost connection very often.
 
Blood sugar input still doesn't work 
There is no 'save' button on the 'enter blood sugar' screen. I have to update my blood sugar using a dedicated receiver. Sometimes the app decides to lose the signal until it is restarted. I hate this update and every day that goes by with these bugs still in the system decreases my faith in my CGM and Dexcom as a whole.
 
Frustrating issues especially with Apple Watch 
I love my Dexcom but there are a number of frustrating issues with this app, some of them new in the most recent revision, I believe. First, I'm no longer getting haptic (vibrating) alerts on my Apple Watch (series 3 with watch OS 4.2.2). I have tried different settings - both do not disturb and without, and having the sound on and off - but unless I'm missing something, the haptics are broken. I do get Dexcom alerts on the watch, but they are visual only. Which is frustrating, since the haptic element is extremely valuable! Also, as other people have said, it is bizarre that dismissing alerts on the watch seems to do nothing on the phone - this needs to be fixed. If you dismiss an alert on the watch, it should communicate with the app instead of having to drag out the phone to avoid constant watch alerts. In addition, the inability to silence the urgent low alarm is a problem - it needs to be vibrate only. As an attorney, I am sometimes in court where if my phone went off, there could be professional consequences! Finally, a relatively minor issue, but if I'm listening to a podcast using the Overcast app, when I open the Dexcom app on my phone, the podcast stops playing. (I have the Dexcom app on the "alerts do not sound" setting.)
 
Update 
After the most recent update, I cannot calibrate. The button to enter the value I type is gone. I have closed the app and reopened. I have restarted my phone. Please fix. This is literally unusable now.
 
Useless now 
With the latest update I am no longer able to enter my blood sugars to calibrate my cgm. The keyboard now covers the green save button. This renders my cgm useless and this is extremely frustrating and frightening since this is a medical device used to keep me from having diabetic seizures.
 
Horrible 
New update is horrible. I've emailed them and nobody is fixing it. Every time I want to calibrate I have to delete the app and redownload it. So annoying.
 
Problem entering calibration BG's 
So I've changed my sensor twice now since the latest update and continue to have this problem: When I tap the green circle to enter my BG the Save button doesn't travel up on the screen. It remains near the bottom, under the key pad or doesn't appear at all. So I can't enter a BG. And the only way to get back to the main screen (not that there's any point, really) is to hard closer the Dexcom app and reopen it. But the problem remains. I've gone am entire day this time without an inexplicable self-fix that usually happens with this glitch. This is not the first time I've had trouble with the keypad getting glitchy on this app. But it seems to be a consistent issue with this update. Any suggestions to fix this? Bare in mind I've already tried closing the app and reopening it AND restarting my iPhone 7 with no success to solve the problem.
 
Won't let me calibrate 
Newest app update won't let me calibrate. App unusable if changing sensors since the keyboard is blocking the save calibration button. Might be time to start looking into Medtronics system since I can't get through to dexcom on the phone/social media/email. Nothing
 
Calibration 
Newest update won't let me calibrate, have to delete and re download app every 6 hours.
 
Latest Update Crashes Constantly 
My App keeps crashing and I’m not sure if it’s when my iPhone is updating apps. Occasionally this happens while I’m asleep so you can imagine the frustration of waking up to an extreme Hypo or Hyper BG. I’ve been trying to problem solve by turning off my Bluetooth, reinstalling the app and reconnecting the Bluetooth. I’ve also turned off my automatic updates, but none of those actions seem to make a difference. Sometimes during the day when I’m using another app it gives me a Lost Signal notification and my Share recipients worry about me and start calling me. This has turned into a huge problem so now I have a backup receiver that doesn’t make an audio sound as loud as I need (like the one on my phone) to wake up.
 
Love the iPhone X Support - BT Audio Issues 
I was very excited with the new update to the G5 app as it finally brought support for the iPhone X screen size. The app works well as far as pulling in BGs from the transmitter. I do still sometimes get Signal Loss, but thanks to the newer transmitters it backfills once it reconnects. My big bummer though right now is the audio from my iPhone pauses if you open the app. This seems to happen with any audio The other big one is outputting to Bluetooth audio devices like my AirPods or my speaker at home. Every 5 or 10 minutes the audio will pause for a few seconds. It comes back, but it’s an annoying disturbance in listening to music or podcasts. Hope Dexcom can fix it soon. Oh also don’t use Third Party keyboards when you try and calibrate because they’ll cause the Save button to disappear and you have to quit the app, change your keyboard and relaunch it.
 
Takes away user choice... 
The Dexcom app upon a sensor failure, etc will refuse to allow me to silence it. Sometimes I’m away from home and don’t have a sensor with me to replace. Forcing me to turn off notifications and close the app to disable the sound is harmful to the user experience. Please stop forcing things upon your users. PS: I’d appreciate if you’d stop sending sensor replacements to a relative and not me. Likely violates HIPPA 😑😑😑
 
Independent Apple Watch support 
It’s been almost a year since the promised update making Apple Watch connect directly with the g5 and bypass needing the phone. What happened?
 
Come on! Give us a mute button! 
4th review Even with an update and even talking with you on the phone. Still haven't got it. Unbelievable. Urgent alarms can't be silenced for my safety?! Are you kidding me? Actually having them not being able to be silenced is a safety hazard!! 3rd review and the #1 requested fix is still not done. It must be the users choice to have alerts for all cases. It's on the user to decide what is important. At no time did my glucose meter jump at me because I hadn't made a test in the last 5 hours. This app should be a tool utilized by the user as they see fit. Give us control of all the alerts! 2nd review: 1 star I love that after countless reviews with a 1 star you guys don't even acknowledge the urgent low sound cannot be disabled on the last update. Give me a break. I understand this might be forced by the FDA, but I thought the FDA approved system was the separate receiver; why can't this app conform to the users requests?!! 1st review: 1 star Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
Great update! 
I’m so glad Dexcom listened to user feedback and allows you to configure the “always sound” option now! Great update!
 
New update makes app impossible to use 
So I can no longer enter my bloodsugars into the app on my phone. Actually, I can put the number in, but I can't enter it after that. There is no 'enter' or 'submit' button. How do I get my bloodsugars in there now? App is useless to me now! Please fix this immediately!
 
Version 1.7.5 won't let me calibrate 
With the new version, when I go to calibrate, the save button is hidden behind the key pad which won't go away. I effectively can't calibrate now!
 
Constant signal loss 
I constantly receive notifications that my signal has been lost. The time I spend trying to address that each day is not worthwhile.
 
New update delivered! 
Below is an old review. I’m happy to say that the new update has fixed any gripe I had with the app. Screen resolution has been updated (for the X and I’m sure others) alarms can be silenced with your phone ringer, and a second schedule can now be programmed! These were my biggest issues with the app and I’m very happy to see they’ve all been addressed in a single update!! First of all, the app isn’t updated to support the resolution of 6/6 plus and newer. Everything is huge on my 8 plus, this should have been addressed 3 years ago. So many alerts that I cannot silence. Most frustrating are the ones that have nothing to do with my BG. I forgot to calibrate this morning and now I get a notification to calibrate what seems like every other minute. I don’t have my lancet so I won’t test till I’m home and there is no way to turn off all these pointless reminders. Apple Watch complication seems to be working about 10% of the time. High/low alerts keep coming unless I open the app on my phone and tap a notification, even though I have the app on my watch. Really hope some updates address all these issues.
 
New version 
So after a year and a half of complaints about un-mutable alerts, the solution is to add in alert schedules, a feature that still doesn’t allow a functional, autonomous adult to make all alerts silent? Do you know what would be perfect? If your garbage app worked the way it did two years ago. If I tell my phone to be silent, it needs to be SILENT. Instead, I have to close the app if I’m in a business meeting (almost every day), at a movie, at a funeral, etc. I guess that’s the safer option right? Isn’t that the goal, Dexcom? Safety? The app used to work beautifully. If I want my phone to be silent, I flip the switch, and EVERYTHING is silent. The way all smartphones and all other apps work. If your algorithm wasn’t so much better than your competitor, I’d jump ship so fast. It’s disappointing that Dexcom has so little regard for their customers.
 
Updated! 
The iPhone X updated finally arrived. Happy with the layout. Not happy that when I go into the app my music stops. Each time. Annoying. Please fix! When will the Watch App work directly with the transmitter?
 
Life-changing 
I’ve been using the Dexcom CGM for several, and the app for maybe two. Both have been life-changers when it comes to managing my diabetes. The sense of security it provides is unmatched, since you can just look at your phone or the Dexcom Receiver whenever you want and see what your BG readings are. It’s usually very accurate. I’m able to catch most lows and highs before they reach extremes with the trend arrow, and I’m able to identify daily trends to adjust my nasal rates. With the app, I’m able to give family members access to my blood sugar at all times. This gives them great peace of mind, and lets them check up on me whenever they wish. Previously, I would have rated this app four stars, because I was frustrated that there was no intermediary setting between vibrating and alarming. On the Dexcom Receiver, you can set it to vibrate first, and then if you don’t confirm it, five minutes later it will alarm. This allowed me to still have the Receiver alarm, but if I was in a situation in which I didn’t want it to alarm, I could cancel it. The app didn’t have such a feature, so I was forced to always leave it on silent. This was more of a problem at night, because I don’t always wake up to the Receiver alarm alone. I suppose I could have manually changed the setting each time I went to bed and each morning when I got up, but I did not make the effort to do that. However, now I don’t have to worry about it. The newest update added an Alert Schedule feature, allowing the user to set customized schedules that changes the alerts, the level at which it alarms, and whether it alarms or just vibrates. This is fantastic, because it means I can create a schedule during the night where it will always alarm, but during the day it will just vibrate. It’s exactly the kind of feature I was hoping for and I am so glad that the Dexcom team has developed it. The only suggestion that I would make now would be to give users the option to have it vibrate first, then alarm after a few minutes if not confirmed, just like it is on the Receiver. I’d like to thank the Dexcom team for their hard work to make life so much easier for us Diabetics.
 
Thank you for this new update 
This update give what the community has been asking for a long time, the alerts where always the most annoying making it hard to do anything but with the new update it makes those problems almost disappear
 
Problem entering calibration BG's 
When I tap the green circle to enter my BG the Save button doesn't travel up on the screen. It remains near the bottom, under the key pad. This is not the first time I've had trouble with the keypad getting glitchy on this app. Any suggestions to fix this? Bare in mind I've already tried closing the app and reopening it AND restarting my iPhone 7 with no success to solve the problem.
 
Game changing CGM 
Hello Devs, what would need to happen for you to enable BG value in notifications? 2/15/18 ———- For the love of science, please add BG value in pop up notification 🙏🏾🙏🏾🙏🏾 Thank you for all you do. **11/29/16** not much to add other than what most have already said here. 24 year T1 diabetic and this has made my life so much easier! Suggested improvements for iOS app: •provide BG in notification alert •allow scrolling and viewing of trends within portrait view •allow more than 24hr trend view (48,72, 1 week?) •not sure if it's Health/apple app issue but allow real time Health app view instead of 3 hour delay. Apple Watch •useful complication w/trend arrow and BG value •option to scroll trend directly on Apple Watch app Thank you for your hard work here!
 
Amazing 
As a newish diabetic I am in love with this app and everything it offers me. I cannot conjure up a reason anyone would want to complain. We are blessed for this app! Directly to our phones, saving lives. THANK YOU!
 
Works okay, but... 
Loses signal far too often and with the new update, I can't input any new blood sugars because the keyboard is covering the submit button.
 
Locked alert settings STILL not fixed after years! 
Still can't disable the urgent low settings. It is too sensitive and frequent, and only necessary to be this loud and frequent when one is asleep. This makes you become an app baby sitter, and if you don't have it right by your side *BEEP BEEP BEEP * in a movie theatre *BEEP BEEP BEEP * in a meeting *BEEP BEEP BEEP * on a date *BEEP BEEP BEEP * at a funeral *BEEP BEEP BEEP **BEEP BEEP BEEP **BEEP BEEP BEEP * BEEEEEEEEEEP! * COME ON DEXCOM !! Diabetes isn't one size fits all! And neither should this app be. For the love of Pete at least allow us to add our own custom sounds that aren't so juvenile and shrill. I'm sorry but great sensor+awful alerts+ignoring years of complaints about these alarms=1 star I would be more generous a few years ago but this had been going on too long. You know once someone else makes a transmitter that can rival your own everyone here will ditch you, right? Just because of these alerts
 
it works! 
it works!
 
You guys still won’t listen 
I used to absolutely love my dexcom but I now can’t stand the thing. I am unable to silence the urgent low and a couple of other alarms. I have a job that requires phones to be silenced during meetings and conferences and this app has made me look like an unprofessional imbecile on more than one occasion. The inability to put the urgent low on silent or vibrate is really making me consider not using this device at all. I continue to give you reviews and you guys continue to ignore what I and many others are telling you what we need and want. Dexcom has gone downhill
 
needs tweaks. 
i don’t understand why my music stops playing when i open the app? extremely annoying. also more annoying that i can’t look at my watch to see my blood sugar because the app always crashes and tells me to look at my phone. incredibly inconvenient with my busy schedule.
 
THANK YOU FOR FIXING ALERTS 
Thank you for the option to mute during certain hours of the day. I am a college student and it is beyond embarrassing when everyone in the class is disturbed by the obnoxious sounds. Finally the fixed it. 5 stars. Thank you thank you
 
After update can't enter BG 
Please assist, I'm unable to enter my BG ever since the app updated. The number keyboard has no way of disappearing in order to hit the green submit button. I reinstalled the app. And have restarted the phone a few times. Nothing fixes it.
 
14 Feb update broke connectivity 
Suddenly we have lots of signal loss on the phone. Not happy!!!
 
Blood sugar input 
Dexcom really bungled this last update and now there is no 'submit' button on the 'enter blood sugar' screen. I guess I could enter my BG from the receiver I have, but then I would have TWO things screaming at me.
 
HELP EMERGENCY 
I CANNOT UPDATE GLUCOSE LEVELS TO CALIBRATE TGE SENSOR WITH THIS NEW UPDATE. HELP ME!
 
Works ok, sensor is great 
I have had a g5 for almost a year now and this is not a review of that. That works almost flawlessly 95% of the time. My issue is with this app. The app adjusts your volume for alerts, but does it terribly. So if music is playing, what you hear is about 1 second of blaring music, then the alert at that volume with the music in the background. Then the sound is reduced about 2 points below what it was originally set at before the alert, before returning to the normal volume about 3 seconds later. Other annoying points about the app: won't let you have a low alert repeat everytime it updates, either no repeating or once every 15 minutes. However, the "enter new bg value" alert does repeat every 5 minutes, becoming endlessly annoying, to the point where I just turn off the whole app. Redeeming qualities: alerts work even when do not disturb is on. Works with pebble smart watches Update: the latest update as of 2-14-2018 has made it impossible to enter a new meter calibration number
 
Terrible Bug 
New update does not allow me to calibrate
 
Bad update 
Ever since the current update, i am unable to save calibration glucose readings, rendering my very expensive dexcom virtually useless
 
Update glitch 
I love having this app, but the newest update has caused a glitch that makes it a bit frustrating to use. When I try to enter a bg value now, I can type in the value, but there is no way to submit it.
 
Calibration button 
After the software update, the calibration button is missing. I'm unable to recalibrate Dexcom.
 
So much better than finger sticks but... 
I love most things about this app but there are certain UX issues that I think need to be addressed. Even with the latest release of alert settings, there are things to be improved. For example, when I insert a new sensor, two hours later I get alerts in the middle of meetings that I can’t silence. I’m not sure how Apple allowed this kind of alert to be an enforced critical alert. Again - Dexcom is on the forefront of using technology but needs to invest more in user experience.
 
Latest update broke the app 
Update: after rebooting my iPhone several times and reinstalling the app, I can enter BG values again. Also glad that alarms can be silenced now! _____________________ I love my G5 but after the latest app update (1.7.5) - I'm not able to enter glucometer readings since the submit/enter button is gone. Hope you fix this ASAP since it's worthless without the ability to calibrate!!
 
Great 
Overall any issues I’ve had have been resolved and feel minor in the grand scheme of things. I can’t live without my dex now. I feel like if I was cured... I would still get one. It’s just always there for me. Absolutely regiment Dexcom. Easier to use compared to Medtronic and I can see it on my watch without weird nightscout workarounds.
 
Help’s a lot 
Let me start by saying I love this it helps me by showing my trends and that helps me snack responsibly that really helps with my over all control. Yes it gets a little annoying when you are low and the constant alerts do case you some times to over correct. It’s like any tool if used well it makes the work easier. Ok now that all said I’m writing here to address the problem that I have found with the latest update. Can’t have a update with out someone having a little hiccup. I uses the Dexcom G5 with my IPhone 6s Plus no problem there but I also like a lot of people listen to music/video/podcast with my Bluetooth headphones and now ever 5min they get softer in sound at first I thought it was my headphones but they work fine with my other device and even other Bluetooth speakers ever 5min get softer this is also noticeable if you just open the app. Please fix with the next update and I will give you back 5 Stars. Sincerely artjte
 
Can't submit readings in latest version 
In the latest version, it won't let me enter blood sugar readings. Very frustrating.
 
Works well; Improved alert options 
Love the sensor and now the app. The February ‘18 release fixes the lack of alert options. Works great so far. Really like the extra schedule option. It took a while, but thanks for listening!
 
Huge Disappointment 
My son, T1D - diagnosed 2 years ago, just recently got the Dexcom G5 not to get into all the hype about the system itself and the huge disappointments there, but just focusing on the many apps we had to download to get started —What? How is this efficient? It could easily be streamlined into one app for all. There is a serious lack of cohesiveness between the apps. Why don’t they at least look the same (symbols and arrows) for ease of use. Not to mention, the elementary graphics and overall poor functionality of the follow app! This was the main reason we got the Dexcom, so I could monitor my son’s numbers while he is sleeping and at his activities throughout the day. The app malfunctions constantly. We get several “no data available” messages. And on the main app that is on my son’s phone he got a message that said he “might have had some acetaminophen and that it can’t read the value properly at the current moment” so it shut down for 2 hours! What?! We are not idiots he didn’t take Tylenol or anything with acetaminophen in it. We just had the Dexcom inserted three days ago and followed the protocol and instruction given to us by a Dexcom rep at our endo doctor. We know you can’t have acetaminophen or the sensor won’t work. This is ridiculous. Also the calibration is awful. It’s always off by a min of 30 points sometimes as much as 55. That’s an unacceptable amount! How was this FDA approved? My sons app was beeping at him like crazy the other night saying he was 49 and when we tested his BG (because he felt fine) he was 88. That’s a big difference. A Difference between a drastic low and being in a perfectly acceptable range. He has to test his BG (just to be sure) as much as he did before we ever inserted the sensor. So how is this an advantage? These apps are glitchy, super glitchy, and childlike in their execution. I’m very disappointed. I hope Apple comes out with a device for continuous glucose monitoring soon because their products and apps work properly and don’t look like kindergarten projects or something from the original Atari days. Would not recommend. Extremely disappointed with the entire Dexcom system (and the sensor tape is already peeling up after 3 days) and the apps! For the amount of money this is just another Big Pharma rip-off.
 
Can't calibrate 
It appears that the most recent version of the app doesn't play well with iOS 11.2.5, as the "save" button for calibrating is covered by the keyboard. The keyboard can't be dismissed. So you can't calibrate the app. At all. I was able to get it calibrated by repeatedly opening and closing the app for 10-15 minutes, but it's a pain in the butt.
 
Finally added some alert controls but keyboard trouble 
Thank you for finally listening to people about the incessant alerts. However, now I’m having trouble entering my blood sugars. The keyboard gets stuck on other keyboards, like Bitmoji, and the save button either gets hidden behind it or disappears so i can’t add my sugars
 
No way to press Enter to enter BG meter values in lastest version on iPad 
Edited February 17, 2018 to change the reading from 1 to 5 after the error in coding was corrected. I can now enter calibration numbers. ................................ Feb. 16, 2018 I've used this a lot. But when I went to enter the calibration values this morning I could key in the numbers but there was no Enter or Save to press. The keypad is covering them up and I can't get rid of it. Please get rid of the app keypad so that I can minimize the regular one and get to the Save button. Currently I cannot calibrate my new sensor!
 
Audio pausing 
With the latest update, I have notice audio pauses every 5 minutes for seconds while listening to Audible or Podcast.
 
Does great things when functional. 
I have not heard anything after reporting this issue to Dexcom, so I will post my findings and workaround here. There is a critical issue in Dexcom G5 Mobile Version 1.7.5 on iOS11.2.5 that prevents users from entering glucose readings / numbers into the app. Once you type the number, you cannot collapse the numpad (There should be save and cancel buttons). You also cannot hit enter on an attached physical keyboard to have the value accepted. The only workaround I have found, is to install a second software keyboard, while the Enter BG Meter Value screen is up, and delete the keyboard in use. This forces the numpad menu to go away and sometimes renders the Save/Cancel buttons. This is not what I consider acceptable functionality for a critical use case application. Not being able to confirm results with a paired, physical keyboard is an anti pattern that's exasperates the ui bug present in 1.7.5.
 
Newest Update is Horrible 
I can't calibrate since the newest update. The keypad goes over the enter button and can't be minimized. May look to the new monitor by Freestyle
 
Please fix 
The new update keeps glitching and I can't calibrate my sensor!! I NEED TO CALIBRATE TO KEEP MY NUMBERS ON POINT. Come on dexcom, you're better than this.
 
Latest Update Has Severe Bugs 
Have used Dexcom app for over year with zero issues, but latest update (while including some welcome upgrades) has severe bugs that prevent calibration and thus make app useless once your sensor requires updating. Over past three days I have twice tried to calibrate and have been prevented from doing so because the "Save" button never appears to confirm the input blood sugar reading. Coupled with a required sensor replacement this effectively makes the app useless. I have tried closing / rebooting app, and restarting iphone with no success. Sometimes the save button *does* appear...but this is perhaps 5% of the time i click the "Calibrate" icon.
 
Love this APP but..... As is it's useless 
Iol give it a 5 as soon as this is fixed. Been using Dexy for 5 + years. They recently did an update to allow accrediting alarms, etc but now I'm unable to calibrate because I can submit the BG #. The keypad won't go away, covering the submit button.
 
Signal loss + interruptions 
This latest version is buggy. I keep losing the signal to my phone and/or am getting the "???" It's a new sensor and I'm not taking Tylenol. Also, annoyingly, this update causes podcasts to stop playing at 4 minute intervals. It usually takes about 3 tries to get them to start playing again, only for them to cease once more several minutes later. It will also stop playing when switching over to the dexcom app. Come on, I'd love to be able to use the app and listen to my stuff without interruption. Wicked lame.
 
Buggy 
Sometimes The ok button is missing on the BG entry screen
 
Weird Volume Bug 
This newest update 1.7.5 is causing my iPhone 7 to randomly lower the volume while playing music, etc. This happens about every 3-5 mins and lasts about 5 seconds, after which the volume goes back up. This issue goes away when I close the app. Very annoying. Otherwise a pretty good app.
 
New update works great except 
If I’m playing music and I enter the app, my music stops. Frustrating at the gym.
 
Loved it until we Purchased a new phone 
The app runs very well on Apple and older Samsung devices but unfortunately with the new galaxy note 8 we are no longer able to put the application on that device. We have to still carry around the Apple phone and tether it. That has been a challenge due to the fact it disconnects. I’m patiently waiting but it’s getting annoying. Please work on this soon.
 
Disappointed with the Apple Watch interface 
I’ve use the Dexcom app on my iPhone for past 2 plus years and have had no issues. I recently added the Apple Watch and I am disappointed that the interface doesn’t accurately reflect current BS levels. Today I was shopping and started feeling some symptoms but a quick look at my watch showed my levels were 142 and rising. I did not go into the app on my watch until I really started to feel the hypo. The watch face still reflected 142 and rising but when I opened the app, it showed 63 and dropping. If the BS number on my watch face had been correct, I could have treated my drop that much sooner. Please work on getting this fixed!
 
No Longer Dependable - Life Threatening 
I don't know if it's the app, sensor or OS, but the connectivity reliability is extremely poor, particularly when in "Do not disturb" Laet evening, 2/10/18, I fell asleep around 10:30pm and my blood sugar was approximately 135. At this point my blood sugar began to drop. While still asleep, I had a notification at 11:58pm to "Enter BG value." My blood sugar at the time was 82. My body woke me up around 1:40 in a state of extreme hypoglycemia. Fortunately, I have glucose tablets on my nightstand and they may have quite literally just saved my life. I checked my phone which was also on my nightstand approximately 1 and a half feet away and there was "no signal." I left the app open in the foreground until it finally regained contact with the sensor at which point the app read "LOW." It's 2:05am, and as I write this my and my BG is still only 47. I could have quite literally just died while wearing Dexcom sensor without ever having received a "LOW" warning from my phone that was less than 2' away. Its a great tool, but it's life threatening to depend on a Dexcom with an iPhone. I'm going to dig out my dedicated receiver tomorrow and hope for better in the future
 
Signal Loss ALL of the time 
I got the Dexcom G5 for my 11 year old daughter over a month ago so I could monitor her blood sugar when she’s at school, her dads and overnight. So far 90% of the time it has said signal loss. There’s no connection when she’s at school ever. For over 24 hours now it has said signal loss and no matter what I do it will not connect!! She’s had her phone next to her the whole time. I am very very disappointed!!
 
Always loses connection to iPhone 7 
We have had this app for 6 months or so. It will pair with my daughters iphone7 but then loses connectivity and then all we get is no data and it stops transmitting. What a horrible experience. Is this because they are behind in staying up to speed with the iPhone updates? You can’t go 6 months between updates and expect to stay current with Apple. This software as is is simply unusable. Lots of promise and ZERO delivery.
 
Dexcom please change this 
First off I want to start off saying I love the device. I work within law enforcement and am honest to say Dexcom made it possible. With that being said I think it is absolutely ridiculous that you are not able to change the URGENT LOW settings to alert you at different time intervals! When speaking to technician support they mentioned that the 30 minute interval was a "safety net" and I totally agree that should be the max amount of time someone should be notified. But the fact that you cannot change the alarm interval to let's say 5 minutes, 10 minutes , or a minute is somewhat scary. If you have diabetes you know how fast a number can raise and fall, and with the dexcom reporting in a little less than real time that could be the difference between life or death. 30 minutes is too long for an urgent low alarm. Dexcom has been more than great to me so I hope they change this soon! Thank you
 
Mute. 
Cmon dexcom. You know what to do. Let Me completely silence all alerts when necessary.
 
Takes away user choice... 
The Dexcom app upon a sensor failure, etc will refuse to allow me to silence it. Sometimes I’m away from home and don’t have a sensor with me to replace. Forcing me to turn off notifications and close the app to disable the sound is harmful to the user experience. Please stop forcing things upon your users. PS: I’d appreciate if you’d stop sending sensor replacements to a relative and not me. Likely violates HIPPA 😑😑😑
 
Independent Apple Watch support 
It’s been almost a year since the promised update making Apple Watch connect directly with the g5 and bypass needing the phone. What happened?
 
Come on! Give us a mute button! 
4th review Even with an update and even talking with you on the phone. Still haven't got it. Unbelievable. Urgent alarms can't be silenced for my safety?! Are you kidding me? Actually having them not being able to be silenced is a safety hazard!! 3rd review and the #1 requested fix is still not done. It must be the users choice to have alerts for all cases. It's on the user to decide what is important. At no time did my glucose meter jump at me because I hadn't made a test in the last 5 hours. This app should be a tool utilized by the user as they see fit. Give us control of all the alerts! 2nd review: 1 star I love that after countless reviews with a 1 star you guys don't even acknowledge the urgent low sound cannot be disabled on the last update. Give me a break. I understand this might be forced by the FDA, but I thought the FDA approved system was the separate receiver; why can't this app conform to the users requests?!! 1st review: 1 star Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
Great update! 
I’m so glad Dexcom listened to user feedback and allows you to configure the “always sound” option now! Great update!
 
New update makes app impossible to use 
So I can no longer enter my bloodsugars into the app on my phone. Actually, I can put the number in, but I can't enter it after that. There is no 'enter' or 'submit' button. How do I get my bloodsugars in there now? App is useless to me now! Please fix this immediately!
 
Version 1.7.5 won't let me calibrate 
With the new version, when I go to calibrate, the save button is hidden behind the key pad which won't go away. I effectively can't calibrate now!
 
Constant signal loss 
I constantly receive notifications that my signal has been lost. The time I spend trying to address that each day is not worthwhile.
 
New update delivered! 
Below is an old review. I’m happy to say that the new update has fixed any gripe I had with the app. Screen resolution has been updated (for the X and I’m sure others) alarms can be silenced with your phone ringer, and a second schedule can now be programmed! These were my biggest issues with the app and I’m very happy to see they’ve all been addressed in a single update!! First of all, the app isn’t updated to support the resolution of 6/6 plus and newer. Everything is huge on my 8 plus, this should have been addressed 3 years ago. So many alerts that I cannot silence. Most frustrating are the ones that have nothing to do with my BG. I forgot to calibrate this morning and now I get a notification to calibrate what seems like every other minute. I don’t have my lancet so I won’t test till I’m home and there is no way to turn off all these pointless reminders. Apple Watch complication seems to be working about 10% of the time. High/low alerts keep coming unless I open the app on my phone and tap a notification, even though I have the app on my watch. Really hope some updates address all these issues.
 
New version 
So after a year and a half of complaints about un-mutable alerts, the solution is to add in alert schedules, a feature that still doesn’t allow a functional, autonomous adult to make all alerts silent? Do you know what would be perfect? If your garbage app worked the way it did two years ago. If I tell my phone to be silent, it needs to be SILENT. Instead, I have to close the app if I’m in a business meeting (almost every day), at a movie, at a funeral, etc. I guess that’s the safer option right? Isn’t that the goal, Dexcom? Safety? The app used to work beautifully. If I want my phone to be silent, I flip the switch, and EVERYTHING is silent. The way all smartphones and all other apps work. If your algorithm wasn’t so much better than your competitor, I’d jump ship so fast. It’s disappointing that Dexcom has so little regard for their customers.
 
Updated! 
The iPhone X updated finally arrived. Happy with the layout. Not happy that when I go into the app my music stops. Each time. Annoying. Please fix! When will the Watch App work directly with the transmitter?
 
Life-changing 
I’ve been using the Dexcom CGM for several, and the app for maybe two. Both have been life-changers when it comes to managing my diabetes. The sense of security it provides is unmatched, since you can just look at your phone or the Dexcom Receiver whenever you want and see what your BG readings are. It’s usually very accurate. I’m able to catch most lows and highs before they reach extremes with the trend arrow, and I’m able to identify daily trends to adjust my nasal rates. With the app, I’m able to give family members access to my blood sugar at all times. This gives them great peace of mind, and lets them check up on me whenever they wish. Previously, I would have rated this app four stars, because I was frustrated that there was no intermediary setting between vibrating and alarming. On the Dexcom Receiver, you can set it to vibrate first, and then if you don’t confirm it, five minutes later it will alarm. This allowed me to still have the Receiver alarm, but if I was in a situation in which I didn’t want it to alarm, I could cancel it. The app didn’t have such a feature, so I was forced to always leave it on silent. This was more of a problem at night, because I don’t always wake up to the Receiver alarm alone. I suppose I could have manually changed the setting each time I went to bed and each morning when I got up, but I did not make the effort to do that. However, now I don’t have to worry about it. The newest update added an Alert Schedule feature, allowing the user to set customized schedules that changes the alerts, the level at which it alarms, and whether it alarms or just vibrates. This is fantastic, because it means I can create a schedule during the night where it will always alarm, but during the day it will just vibrate. It’s exactly the kind of feature I was hoping for and I am so glad that the Dexcom team has developed it. The only suggestion that I would make now would be to give users the option to have it vibrate first, then alarm after a few minutes if not confirmed, just like it is on the Receiver. I’d like to thank the Dexcom team for their hard work to make life so much easier for us Diabetics.
 
Thank you for this new update 
This update give what the community has been asking for a long time, the alerts where always the most annoying making it hard to do anything but with the new update it makes those problems almost disappear
 
Problem entering calibration BG's 
When I tap the green circle to enter my BG the Save button doesn't travel up on the screen. It remains near the bottom, under the key pad. This is not the first time I've had trouble with the keypad getting glitchy on this app. Any suggestions to fix this? Bare in mind I've already tried closing the app and reopening it AND restarting my iPhone 7 with no success to solve the problem.
 
Game changing CGM 
Hello Devs, what would need to happen for you to enable BG value in notifications? 2/15/18 ———- For the love of science, please add BG value in pop up notification 🙏🏾🙏🏾🙏🏾 Thank you for all you do. **11/29/16** not much to add other than what most have already said here. 24 year T1 diabetic and this has made my life so much easier! Suggested improvements for iOS app: •provide BG in notification alert •allow scrolling and viewing of trends within portrait view •allow more than 24hr trend view (48,72, 1 week?) •not sure if it's Health/apple app issue but allow real time Health app view instead of 3 hour delay. Apple Watch •useful complication w/trend arrow and BG value •option to scroll trend directly on Apple Watch app Thank you for your hard work here!
 
Amazing 
As a newish diabetic I am in love with this app and everything it offers me. I cannot conjure up a reason anyone would want to complain. We are blessed for this app! Directly to our phones, saving lives. THANK YOU!
 
Works okay, but... 
Loses signal far too often and with the new update, I can't input any new blood sugars because the keyboard is covering the submit button.
 
Locked alert settings STILL not fixed after years! 
Still can't disable the urgent low settings. It is too sensitive and frequent, and only necessary to be this loud and frequent when one is asleep. This makes you become an app baby sitter, and if you don't have it right by your side *BEEP BEEP BEEP * in a movie theatre *BEEP BEEP BEEP * in a meeting *BEEP BEEP BEEP * on a date *BEEP BEEP BEEP * at a funeral *BEEP BEEP BEEP **BEEP BEEP BEEP **BEEP BEEP BEEP * BEEEEEEEEEEP! * COME ON DEXCOM !! Diabetes isn't one size fits all! And neither should this app be. For the love of Pete at least allow us to add our own custom sounds that aren't so juvenile and shrill. I'm sorry but great sensor+awful alerts+ignoring years of complaints about these alarms=1 star I would be more generous a few years ago but this had been going on too long. You know once someone else makes a transmitter that can rival your own everyone here will ditch you, right? Just because of these alerts
 
it works! 
it works!
 
You guys still won’t listen 
I used to absolutely love my dexcom but I now can’t stand the thing. I am unable to silence the urgent low and a couple of other alarms. I have a job that requires phones to be silenced during meetings and conferences and this app has made me look like an unprofessional imbecile on more than one occasion. The inability to put the urgent low on silent or vibrate is really making me consider not using this device at all. I continue to give you reviews and you guys continue to ignore what I and many others are telling you what we need and want. Dexcom has gone downhill
 
needs tweaks. 
i don’t understand why my music stops playing when i open the app? extremely annoying. also more annoying that i can’t look at my watch to see my blood sugar because the app always crashes and tells me to look at my phone. incredibly inconvenient with my busy schedule.
 
THANK YOU FOR FIXING ALERTS 
Thank you for the option to mute during certain hours of the day. I am a college student and it is beyond embarrassing when everyone in the class is disturbed by the obnoxious sounds. Finally the fixed it. 5 stars. Thank you thank you
 
After update can't enter BG 
Please assist, I'm unable to enter my BG ever since the app updated. The number keyboard has no way of disappearing in order to hit the green submit button. I reinstalled the app. And have restarted the phone a few times. Nothing fixes it.
 
14 Feb update broke connectivity 
Suddenly we have lots of signal loss on the phone. Not happy!!!
 
Blood sugar input 
Dexcom really bungled this last update and now there is no 'submit' button on the 'enter blood sugar' screen. I guess I could enter my BG from the receiver I have, but then I would have TWO things screaming at me.
 
HELP EMERGENCY 
I CANNOT UPDATE GLUCOSE LEVELS TO CALIBRATE TGE SENSOR WITH THIS NEW UPDATE. HELP ME!
 
Works ok, sensor is great 
I have had a g5 for almost a year now and this is not a review of that. That works almost flawlessly 95% of the time. My issue is with this app. The app adjusts your volume for alerts, but does it terribly. So if music is playing, what you hear is about 1 second of blaring music, then the alert at that volume with the music in the background. Then the sound is reduced about 2 points below what it was originally set at before the alert, before returning to the normal volume about 3 seconds later. Other annoying points about the app: won't let you have a low alert repeat everytime it updates, either no repeating or once every 15 minutes. However, the "enter new bg value" alert does repeat every 5 minutes, becoming endlessly annoying, to the point where I just turn off the whole app. Redeeming qualities: alerts work even when do not disturb is on. Works with pebble smart watches Update: the latest update as of 2-14-2018 has made it impossible to enter a new meter calibration number
 
Terrible Bug 
New update does not allow me to calibrate
 
Bad update 
Ever since the current update, i am unable to save calibration glucose readings, rendering my very expensive dexcom virtually useless
 
Update glitch 
I love having this app, but the newest update has caused a glitch that makes it a bit frustrating to use. When I try to enter a bg value now, I can type in the value, but there is no way to submit it.
 
Calibration button 
After the software update, the calibration button is missing. I'm unable to recalibrate Dexcom.
 
So much better than finger sticks but... 
I love most things about this app but there are certain UX issues that I think need to be addressed. Even with the latest release of alert settings, there are things to be improved. For example, when I insert a new sensor, two hours later I get alerts in the middle of meetings that I can’t silence. I’m not sure how Apple allowed this kind of alert to be an enforced critical alert. Again - Dexcom is on the forefront of using technology but needs to invest more in user experience.
 
Latest update broke the app 
Update: after rebooting my iPhone several times and reinstalling the app, I can enter BG values again. Also glad that alarms can be silenced now! _____________________ I love my G5 but after the latest app update (1.7.5) - I'm not able to enter glucometer readings since the submit/enter button is gone. Hope you fix this ASAP since it's worthless without the ability to calibrate!!
 
Great 
Overall any issues I’ve had have been resolved and feel minor in the grand scheme of things. I can’t live without my dex now. I feel like if I was cured... I would still get one. It’s just always there for me. Absolutely regiment Dexcom. Easier to use compared to Medtronic and I can see it on my watch without weird nightscout workarounds.
 
Help’s a lot 
Let me start by saying I love this it helps me by showing my trends and that helps me snack responsibly that really helps with my over all control. Yes it gets a little annoying when you are low and the constant alerts do case you some times to over correct. It’s like any tool if used well it makes the work easier. Ok now that all said I’m writing here to address the problem that I have found with the latest update. Can’t have a update with out someone having a little hiccup. I uses the Dexcom G5 with my IPhone 6s Plus no problem there but I also like a lot of people listen to music/video/podcast with my Bluetooth headphones and now ever 5min they get softer in sound at first I thought it was my headphones but they work fine with my other device and even other Bluetooth speakers ever 5min get softer this is also noticeable if you just open the app. Please fix with the next update and I will give you back 5 Stars. Sincerely artjte
 
Can't submit readings in latest version 
In the latest version, it won't let me enter blood sugar readings. Very frustrating.
 
Works well; Improved alert options 
Love the sensor and now the app. The February ‘18 release fixes the lack of alert options. Works great so far. Really like the extra schedule option. It took a while, but thanks for listening!
 
Huge Disappointment 
My son, T1D - diagnosed 2 years ago, just recently got the Dexcom G5 not to get into all the hype about the system itself and the huge disappointments there, but just focusing on the many apps we had to download to get started —What? How is this efficient? It could easily be streamlined into one app for all. There is a serious lack of cohesiveness between the apps. Why don’t they at least look the same (symbols and arrows) for ease of use. Not to mention, the elementary graphics and overall poor functionality of the follow app! This was the main reason we got the Dexcom, so I could monitor my son’s numbers while he is sleeping and at his activities throughout the day. The app malfunctions constantly. We get several “no data available” messages. And on the main app that is on my son’s phone he got a message that said he “might have had some acetaminophen and that it can’t read the value properly at the current moment” so it shut down for 2 hours! What?! We are not idiots he didn’t take Tylenol or anything with acetaminophen in it. We just had the Dexcom inserted three days ago and followed the protocol and instruction given to us by a Dexcom rep at our endo doctor. We know you can’t have acetaminophen or the sensor won’t work. This is ridiculous. Also the calibration is awful. It’s always off by a min of 30 points sometimes as much as 55. That’s an unacceptable amount! How was this FDA approved? My sons app was beeping at him like crazy the other night saying he was 49 and when we tested his BG (because he felt fine) he was 88. That’s a big difference. A Difference between a drastic low and being in a perfectly acceptable range. He has to test his BG (just to be sure) as much as he did before we ever inserted the sensor. So how is this an advantage? These apps are glitchy, super glitchy, and childlike in their execution. I’m very disappointed. I hope Apple comes out with a device for continuous glucose monitoring soon because their products and apps work properly and don’t look like kindergarten projects or something from the original Atari days. Would not recommend. Extremely disappointed with the entire Dexcom system (and the sensor tape is already peeling up after 3 days) and the apps! For the amount of money this is just another Big Pharma rip-off.
 
Can't calibrate 
It appears that the most recent version of the app doesn't play well with iOS 11.2.5, as the "save" button for calibrating is covered by the keyboard. The keyboard can't be dismissed. So you can't calibrate the app. At all. I was able to get it calibrated by repeatedly opening and closing the app for 10-15 minutes, but it's a pain in the butt.
 
Finally added some alert controls but keyboard trouble 
Thank you for finally listening to people about the incessant alerts. However, now I’m having trouble entering my blood sugars. The keyboard gets stuck on other keyboards, like Bitmoji, and the save button either gets hidden behind it or disappears so i can’t add my sugars
 
No way to press Enter to enter BG meter values in lastest version on iPad 
Edited February 17, 2018 to change the reading from 1 to 5 after the error in coding was corrected. I can now enter calibration numbers. ................................ Feb. 16, 2018 I've used this a lot. But when I went to enter the calibration values this morning I could key in the numbers but there was no Enter or Save to press. The keypad is covering them up and I can't get rid of it. Please get rid of the app keypad so that I can minimize the regular one and get to the Save button. Currently I cannot calibrate my new sensor!
 
Audio pausing 
With the latest update, I have notice audio pauses every 5 minutes for seconds while listening to Audible or Podcast.
 
Does great things when functional. 
I have not heard anything after reporting this issue to Dexcom, so I will post my findings and workaround here. There is a critical issue in Dexcom G5 Mobile Version 1.7.5 on iOS11.2.5 that prevents users from entering glucose readings / numbers into the app. Once you type the number, you cannot collapse the numpad (There should be save and cancel buttons). You also cannot hit enter on an attached physical keyboard to have the value accepted. The only workaround I have found, is to install a second software keyboard, while the Enter BG Meter Value screen is up, and delete the keyboard in use. This forces the numpad menu to go away and sometimes renders the Save/Cancel buttons. This is not what I consider acceptable functionality for a critical use case application. Not being able to confirm results with a paired, physical keyboard is an anti pattern that's exasperates the ui bug present in 1.7.5.
 
Newest Update is Horrible 
I can't calibrate since the newest update. The keypad goes over the enter button and can't be minimized. May look to the new monitor by Freestyle
 
The Three Question Marks 
I cannot go 30 min with my dexcom without the stupid alarm going off that says I have a signal loss of the three question marks. Ill be sitting in class monitoring my bg then all of the sudden 5 min later it says signal loss. It doesn’t make sense!
 
Dexcom 
I’m a type one diabetic and I’ve had Dexcomg5 for a while now and I love it! But this update is really terrible it’s really embarrassing at work or when I’m with friends at a movie or dinner with my family and I get really no sleep anymore.
 
Losses signal A lot 
Been wearing dexcom for a week and the monitor loses signal a lot. And then I get a notification that app is closed you will not get any reading. It’s nice to have your readings handy but they need to fix the app pronto. A lot of diabetics are counting on this device and app.
 
Ability to utilize this app on more than one device 
My daughter is T1D and we have been using DEXCOM for about 9 months with some mixed results. *****She switches between three caregivers, my ex wife and I as well as her grandparents and to include her school nurse. Her school doesn’t have WIFI or plan to have WIFI. I find it ridiculous to have to buy a cell phone and service plan for my 2nd grade daughter for the sole reason that all caregivers to be notified of alerts when she already carry’s the dexcom monitor. Why can’t this App be utilized by multiple phones/people if or when needed even if it’s the same password and username being shared? Why can’t or why hasn’t anyone addressed the issue regarding this as I know I am not the only parent that has this problem. I have a great Dexcom Rep and she even says yes she agrees but doesn’t know if or when this may happen. ****Any help or thoughts would be greatly appreciated. I could totally just be misunderstanding the technology side of this app but again I wouldn’t be the only parent I know to have similar issues.
 
Please change alarm settings! 
Like a lot of other users, I hope that Dexcom changes its alarm system. It would be awesome if you could set the alarm by time, so that if you're in class or at work the urgent low alarm would only vibrate but at home and at night it would be an audible alarm. Or the alarm vibrates once and if you don’t acknowledge in the app switch to an audible alarm. It’s gotten to the point where I have to completely turn off my phone when I go to the movies or take a test so I don’t disturb others. This defeats the point of being alerted when I have low blood sugar. Please change this Dexcom.
 
Hate hate hate the new update 
I have type 1 diabetes and began wearing the Dexcom CGM 4 years ago. It was great, until they upgraded the ap in early 2017. I stopped wearing it for awhile but enjoyed the ease of knowing what my blood sugars were throughout the day so tried it again. What I didn’t enjoy was the ear piercing noise that my phone would emit for a critical low of 55 mg/dL. (With the accuracy of Dexcom, this could actually be in the 70 range) Nearly every time it happened, I was already working to correct the low. As anyone with diabetes on insulin knows, there is often a significant delay between correcting a low and then seeing blood sugar rise on the Dexcom. This alarm resulted in loss of sleep and embarrassment in social situations, movies, meetings, etc. I continued to wear the Dexcom because there was no other option. I continued to contact Dexcom to ask that they allow for a vibrate during a critical low, followed by noise if there was no response by the user. I was desperate to have my life back without the constant fear of the alarm going off. After no feedback or improvement in the ap from dexcom, I have switched over to the new (in the US) Freestyle libre which is a game changer. More accurate and no annoying alarms like the Dexcom. I am a physician and am now recommending the libre to all of my patients. Very unfortunate, I had high hopes for Dexcom ***Update: anyone reading this, read my complaint and then the developers response. They didn’t even address any of my concerns! They only discussed issues with Android. I don’t own an android device and never mentioned this in my comment. It shows how out of touch this company is with its customers.
 
Just alright 
Well this is ok! When I go into the app it always says no signal after I go into the app then it will start showing the reading but if I don’t Go into the app in an hour so it will be back to saying no signal it’s kind of annoying does anyone know if the series 3 Apple Watch will work with this app without pairing with a phone ?!?
 
Loved it until we Purchased a new phone 
The app runs very well on Apple and older Samsung devices but unfortunately with the new galaxy note 8 we are no longer able to put the application on that device. We have to still carry around the Apple phone and tether it. That has been a challenge due to the fact it disconnects. I’m patiently waiting but it’s getting annoying. Please work on this soon.
 
Disappointed with the Apple Watch interface 
I’ve use the Dexcom app on my iPhone for past 2 plus years and have had no issues. I recently added the Apple Watch and I am disappointed that the interface doesn’t accurately reflect current BS levels. Today I was shopping and started feeling some symptoms but a quick look at my watch showed my levels were 142 and rising. I did not go into the app on my watch until I really started to feel the hypo. The watch face still reflected 142 and rising but when I opened the app, it showed 63 and dropping. If the BS number on my watch face had been correct, I could have treated my drop that much sooner. Please work on getting this fixed!
 
No Longer Dependable - Life Threatening 
I don't know if it's the app, sensor or OS, but the connectivity reliability is extremely poor, particularly when in "Do not disturb" Laet evening, 2/10/18, I fell asleep around 10:30pm and my blood sugar was approximately 135. At this point my blood sugar began to drop. While still asleep, I had a notification at 11:58pm to "Enter BG value." My blood sugar at the time was 82. My body woke me up around 1:40 in a state of extreme hypoglycemia. Fortunately, I have glucose tablets on my nightstand and they may have quite literally just saved my life. I checked my phone which was also on my nightstand approximately 1 and a half feet away and there was "no signal." I left the app open in the foreground until it finally regained contact with the sensor at which point the app read "LOW." It's 2:05am, and as I write this my and my BG is still only 47. I could have quite literally just died while wearing Dexcom sensor without ever having received a "LOW" warning from my phone that was less than 2' away. Its a great tool, but it's life threatening to depend on a Dexcom with an iPhone. I'm going to dig out my dedicated receiver tomorrow and hope for better in the future
 
Signal Loss ALL of the time 
I got the Dexcom G5 for my 11 year old daughter over a month ago so I could monitor her blood sugar when she’s at school, her dads and overnight. So far 90% of the time it has said signal loss. There’s no connection when she’s at school ever. For over 24 hours now it has said signal loss and no matter what I do it will not connect!! She’s had her phone next to her the whole time. I am very very disappointed!!
 
Always loses connection to iPhone 7 
We have had this app for 6 months or so. It will pair with my daughters iphone7 but then loses connectivity and then all we get is no data and it stops transmitting. What a horrible experience. Is this because they are behind in staying up to speed with the iPhone updates? You can’t go 6 months between updates and expect to stay current with Apple. This software as is is simply unusable. Lots of promise and ZERO delivery.
 
Dexcom please change this 
First off I want to start off saying I love the device. I work within law enforcement and am honest to say Dexcom made it possible. With that being said I think it is absolutely ridiculous that you are not able to change the URGENT LOW settings to alert you at different time intervals! When speaking to technician support they mentioned that the 30 minute interval was a "safety net" and I totally agree that should be the max amount of time someone should be notified. But the fact that you cannot change the alarm interval to let's say 5 minutes, 10 minutes , or a minute is somewhat scary. If you have diabetes you know how fast a number can raise and fall, and with the dexcom reporting in a little less than real time that could be the difference between life or death. 30 minutes is too long for an urgent low alarm. Dexcom has been more than great to me so I hope they change this soon! Thank you
 
Mute. 
Cmon dexcom. You know what to do. Let Me completely silence all alerts when necessary.
 
Takes away user choice... 
The Dexcom app upon a sensor failure, etc will refuse to allow me to silence it. Sometimes I’m away from home and don’t have a sensor with me to replace. Forcing me to turn off notifications and close the app to disable the sound is harmful to the user experience. Please stop forcing things upon your users. PS: I’d appreciate if you’d stop sending sensor replacements to a relative and not me. Likely violates HIPPA 😑😑😑
 
Independent Apple Watch support 
It’s been almost a year since the promised update making Apple Watch connect directly with the g5 and bypass needing the phone. What happened?
 
Come on! Give us a mute button! 
4th review Even with an update and even talking with you on the phone. Still haven't got it. Unbelievable. Urgent alarms can't be silenced for my safety?! Are you kidding me? Actually having them not being able to be silenced is a safety hazard!! 3rd review and the #1 requested fix is still not done. It must be the users choice to have alerts for all cases. It's on the user to decide what is important. At no time did my glucose meter jump at me because I hadn't made a test in the last 5 hours. This app should be a tool utilized by the user as they see fit. Give us control of all the alerts! 2nd review: 1 star I love that after countless reviews with a 1 star you guys don't even acknowledge the urgent low sound cannot be disabled on the last update. Give me a break. I understand this might be forced by the FDA, but I thought the FDA approved system was the separate receiver; why can't this app conform to the users requests?!! 1st review: 1 star Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
Great update! 
I’m so glad Dexcom listened to user feedback and allows you to configure the “always sound” option now! Great update!
 
New update makes app impossible to use 
So I can no longer enter my bloodsugars into the app on my phone. Actually, I can put the number in, but I can't enter it after that. There is no 'enter' or 'submit' button. How do I get my bloodsugars in there now? App is useless to me now! Please fix this immediately!
 
Version 1.7.5 won't let me calibrate 
With the new version, when I go to calibrate, the save button is hidden behind the key pad which won't go away. I effectively can't calibrate now!
 
Constant signal loss 
I constantly receive notifications that my signal has been lost. The time I spend trying to address that each day is not worthwhile.
 
New update delivered! 
Below is an old review. I’m happy to say that the new update has fixed any gripe I had with the app. Screen resolution has been updated (for the X and I’m sure others) alarms can be silenced with your phone ringer, and a second schedule can now be programmed! These were my biggest issues with the app and I’m very happy to see they’ve all been addressed in a single update!! First of all, the app isn’t updated to support the resolution of 6/6 plus and newer. Everything is huge on my 8 plus, this should have been addressed 3 years ago. So many alerts that I cannot silence. Most frustrating are the ones that have nothing to do with my BG. I forgot to calibrate this morning and now I get a notification to calibrate what seems like every other minute. I don’t have my lancet so I won’t test till I’m home and there is no way to turn off all these pointless reminders. Apple Watch complication seems to be working about 10% of the time. High/low alerts keep coming unless I open the app on my phone and tap a notification, even though I have the app on my watch. Really hope some updates address all these issues.
 
New version 
So after a year and a half of complaints about un-mutable alerts, the solution is to add in alert schedules, a feature that still doesn’t allow a functional, autonomous adult to make all alerts silent? Do you know what would be perfect? If your garbage app worked the way it did two years ago. If I tell my phone to be silent, it needs to be SILENT. Instead, I have to close the app if I’m in a business meeting (almost every day), at a movie, at a funeral, etc. I guess that’s the safer option right? Isn’t that the goal, Dexcom? Safety? The app used to work beautifully. If I want my phone to be silent, I flip the switch, and EVERYTHING is silent. The way all smartphones and all other apps work. If your algorithm wasn’t so much better than your competitor, I’d jump ship so fast. It’s disappointing that Dexcom has so little regard for their customers.
 
Updated! 
The iPhone X updated finally arrived. Happy with the layout. Not happy that when I go into the app my music stops. Each time. Annoying. Please fix! When will the Watch App work directly with the transmitter?
 
Life-changing 
I’ve been using the Dexcom CGM for several, and the app for maybe two. Both have been life-changers when it comes to managing my diabetes. The sense of security it provides is unmatched, since you can just look at your phone or the Dexcom Receiver whenever you want and see what your BG readings are. It’s usually very accurate. I’m able to catch most lows and highs before they reach extremes with the trend arrow, and I’m able to identify daily trends to adjust my nasal rates. With the app, I’m able to give family members access to my blood sugar at all times. This gives them great peace of mind, and lets them check up on me whenever they wish. Previously, I would have rated this app four stars, because I was frustrated that there was no intermediary setting between vibrating and alarming. On the Dexcom Receiver, you can set it to vibrate first, and then if you don’t confirm it, five minutes later it will alarm. This allowed me to still have the Receiver alarm, but if I was in a situation in which I didn’t want it to alarm, I could cancel it. The app didn’t have such a feature, so I was forced to always leave it on silent. This was more of a problem at night, because I don’t always wake up to the Receiver alarm alone. I suppose I could have manually changed the setting each time I went to bed and each morning when I got up, but I did not make the effort to do that. However, now I don’t have to worry about it. The newest update added an Alert Schedule feature, allowing the user to set customized schedules that changes the alerts, the level at which it alarms, and whether it alarms or just vibrates. This is fantastic, because it means I can create a schedule during the night where it will always alarm, but during the day it will just vibrate. It’s exactly the kind of feature I was hoping for and I am so glad that the Dexcom team has developed it. The only suggestion that I would make now would be to give users the option to have it vibrate first, then alarm after a few minutes if not confirmed, just like it is on the Receiver. I’d like to thank the Dexcom team for their hard work to make life so much easier for us Diabetics.
 
Thank you for this new update 
This update give what the community has been asking for a long time, the alerts where always the most annoying making it hard to do anything but with the new update it makes those problems almost disappear
 
Problem entering calibration BG's 
When I tap the green circle to enter my BG the Save button doesn't travel up on the screen. It remains near the bottom, under the key pad. This is not the first time I've had trouble with the keypad getting glitchy on this app. Any suggestions to fix this? Bare in mind I've already tried closing the app and reopening it AND restarting my iPhone 7 with no success to solve the problem.
 
Game changing CGM 
Hello Devs, what would need to happen for you to enable BG value in notifications? 2/15/18 ———- For the love of science, please add BG value in pop up notification 🙏🏾🙏🏾🙏🏾 Thank you for all you do. **11/29/16** not much to add other than what most have already said here. 24 year T1 diabetic and this has made my life so much easier! Suggested improvements for iOS app: •provide BG in notification alert •allow scrolling and viewing of trends within portrait view •allow more than 24hr trend view (48,72, 1 week?) •not sure if it's Health/apple app issue but allow real time Health app view instead of 3 hour delay. Apple Watch •useful complication w/trend arrow and BG value •option to scroll trend directly on Apple Watch app Thank you for your hard work here!
 
Amazing 
As a newish diabetic I am in love with this app and everything it offers me. I cannot conjure up a reason anyone would want to complain. We are blessed for this app! Directly to our phones, saving lives. THANK YOU!
 
Works okay, but... 
Loses signal far too often and with the new update, I can't input any new blood sugars because the keyboard is covering the submit button.
 
Locked alert settings STILL not fixed after years! 
Still can't disable the urgent low settings. It is too sensitive and frequent, and only necessary to be this loud and frequent when one is asleep. This makes you become an app baby sitter, and if you don't have it right by your side *BEEP BEEP BEEP * in a movie theatre *BEEP BEEP BEEP * in a meeting *BEEP BEEP BEEP * on a date *BEEP BEEP BEEP * at a funeral *BEEP BEEP BEEP **BEEP BEEP BEEP **BEEP BEEP BEEP * BEEEEEEEEEEP! * COME ON DEXCOM !! Diabetes isn't one size fits all! And neither should this app be. For the love of Pete at least allow us to add our own custom sounds that aren't so juvenile and shrill. I'm sorry but great sensor+awful alerts+ignoring years of complaints about these alarms=1 star I would be more generous a few years ago but this had been going on too long. You know once someone else makes a transmitter that can rival your own everyone here will ditch you, right? Just because of these alerts
 
it works! 
it works!
 
You guys still won’t listen 
I used to absolutely love my dexcom but I now can’t stand the thing. I am unable to silence the urgent low and a couple of other alarms. I have a job that requires phones to be silenced during meetings and conferences and this app has made me look like an unprofessional imbecile on more than one occasion. The inability to put the urgent low on silent or vibrate is really making me consider not using this device at all. I continue to give you reviews and you guys continue to ignore what I and many others are telling you what we need and want. Dexcom has gone downhill
 
needs tweaks. 
i don’t understand why my music stops playing when i open the app? extremely annoying. also more annoying that i can’t look at my watch to see my blood sugar because the app always crashes and tells me to look at my phone. incredibly inconvenient with my busy schedule.
 
THANK YOU FOR FIXING ALERTS 
Thank you for the option to mute during certain hours of the day. I am a college student and it is beyond embarrassing when everyone in the class is disturbed by the obnoxious sounds. Finally the fixed it. 5 stars. Thank you thank you
 
The Three Question Marks 
I cannot go 30 min with my dexcom without the stupid alarm going off that says I have a signal loss of the three question marks. Ill be sitting in class monitoring my bg then all of the sudden 5 min later it says signal loss. It doesn’t make sense!
 
Dexcom 
I’m a type one diabetic and I’ve had Dexcomg5 for a while now and I love it! But this update is really terrible it’s really embarrassing at work or when I’m with friends at a movie or dinner with my family and I get really no sleep anymore.
 
Losses signal A lot 
Been wearing dexcom for a week and the monitor loses signal a lot. And then I get a notification that app is closed you will not get any reading. It’s nice to have your readings handy but they need to fix the app pronto. A lot of diabetics are counting on this device and app.
 
Ability to utilize this app on more than one device 
My daughter is T1D and we have been using DEXCOM for about 9 months with some mixed results. *****She switches between three caregivers, my ex wife and I as well as her grandparents and to include her school nurse. Her school doesn’t have WIFI or plan to have WIFI. I find it ridiculous to have to buy a cell phone and service plan for my 2nd grade daughter for the sole reason that all caregivers to be notified of alerts when she already carry’s the dexcom monitor. Why can’t this App be utilized by multiple phones/people if or when needed even if it’s the same password and username being shared? Why can’t or why hasn’t anyone addressed the issue regarding this as I know I am not the only parent that has this problem. I have a great Dexcom Rep and she even says yes she agrees but doesn’t know if or when this may happen. ****Any help or thoughts would be greatly appreciated. I could totally just be misunderstanding the technology side of this app but again I wouldn’t be the only parent I know to have similar issues.
 
Please change alarm settings! 
Like a lot of other users, I hope that Dexcom changes its alarm system. It would be awesome if you could set the alarm by time, so that if you're in class or at work the urgent low alarm would only vibrate but at home and at night it would be an audible alarm. Or the alarm vibrates once and if you don’t acknowledge in the app switch to an audible alarm. It’s gotten to the point where I have to completely turn off my phone when I go to the movies or take a test so I don’t disturb others. This defeats the point of being alerted when I have low blood sugar. Please change this Dexcom.

I left the app open in the foreground until it finally regained contact with the sensor at which point the app read "LOW." It's 2:05am, and as I write this my and my BG is still only 47. I could have quite literally just died while wearing Dexcom sensor without ever having received a "LOW" warning from my phone that was less than 2' away. Its a great tool, but it's life threatening to depend on a Dexcom with an iPhone. I'm going to dig out my dedicated receiver tomorrow and hope for better in the future
 
Signal Loss ALL of the time 
I got the Dexcom G5 for my 11 year old daughter over a month ago so I could monitor her blood sugar when she’s at school, her dads and overnight. So far 90% of the time it has said signal loss. There’s no connection when she’s at school ever. For over 24 hours now it has said signal loss and no matter what I do it will not connect!! She’s had her phone next to her the whole time. I am very very disappointed!!
 
Always loses connection to iPhone 7 
We have had this app for 6 months or so. It will pair with my daughters iphone7 but then loses connectivity and then all we get is no data and it stops transmitting. What a horrible experience. Is this because they are behind in staying up to speed with the iPhone updates? You can’t go 6 months between updates and expect to stay current with Apple. This software as is is simply unusable. Lots of promise and ZERO delivery.
 
The Three Question Marks 
I cannot go 30 min with my dexcom without the stupid alarm going off that says I have a signal loss of the three question marks. Ill be sitting in class monitoring my bg then all of the sudden 5 min later it says signal loss. It doesn’t make sense!
 
Dexcom 
I’m a type one diabetic and I’ve had Dexcomg5 for a while now and I love it! But this update is really terrible it’s really embarrassing at work or when I’m with friends at a movie or dinner with my family and I get really no sleep anymore.
 
Losses signal A lot 
Been wearing dexcom for a week and the monitor loses signal a lot. And then I get a notification that app is closed you will not get any reading. It’s nice to have your readings handy but they need to fix the app pronto. A lot of diabetics are counting on this device and app.
 
Ability to utilize this app on more than one device 
My daughter is T1D and we have been using DEXCOM for about 9 months with some mixed results. *****She switches between three caregivers, my ex wife and I as well as her grandparents and to include her school nurse. Her school doesn’t have WIFI or plan to have WIFI. I find it ridiculous to have to buy a cell phone and service plan for my 2nd grade daughter for the sole reason that all caregivers to be notified of alerts when she already carry’s the dexcom monitor. Why can’t this App be utilized by multiple phones/people if or when needed even if it’s the same password and username being shared? Why can’t or why hasn’t anyone addressed the issue regarding this as I know I am not the only parent that has this problem. I have a great Dexcom Rep and she even says yes she agrees but doesn’t know if or when this may happen. ****Any help or thoughts would be greatly appreciated. I could totally just be misunderstanding the technology side of this app but again I wouldn’t be the only parent I know to have similar issues.
 
Please change alarm settings! 
Like a lot of other users, I hope that Dexcom changes its alarm system. It would be awesome if you could set the alarm by time, so that if you're in class or at work the urgent low alarm would only vibrate but at home and at night it would be an audible alarm. Or the alarm vibrates once and if you don’t acknowledge in the app switch to an audible alarm. It’s gotten to the point where I have to completely turn off my phone when I go to the movies or take a test so I don’t disturb others. This defeats the point of being alerted when I have low blood sugar. Please change this Dexcom.
 
Hate hate hate the new update 
I have type 1 diabetes and began wearing the Dexcom CGM 4 years ago. It was great, until they upgraded the ap in early 2017. I stopped wearing it for awhile but enjoyed the ease of knowing what my blood sugars were throughout the day so tried it again. What I didn’t enjoy was the ear piercing noise that my phone would emit for a critical low of 55 mg/dL. (With the accuracy of Dexcom, this could actually be in the 70 range) Nearly every time it happened, I was already working to correct the low. As anyone with diabetes on insulin knows, there is often a significant delay between correcting a low and then seeing blood sugar rise on the Dexcom. This alarm resulted in loss of sleep and embarrassment in social situations, movies, meetings, etc. I continued to wear the Dexcom because there was no other option. I continued to contact Dexcom to ask that they allow for a vibrate during a critical low, followed by noise if there was no response by the user. I was desperate to have my life back without the constant fear of the alarm going off. After no feedback or improvement in the ap from dexcom, I have switched over to the new (in the US) Freestyle libre which is a game changer. More accurate and no annoying alarms like the Dexcom. I am a physician and am now recommending the libre to all of my patients. Very unfortunate, I had high hopes for Dexcom ***Update: anyone reading this, read my complaint and then the developers response. They didn’t even address any of my concerns! They only discussed issues with Android. I don’t own an android device and never mentioned this in my comment. It shows how out of touch this company is with its customers.
 
Just alright 
Well this is ok! When I go into the app it always says no signal after I go into the app then it will start showing the reading but if I don’t Go into the app in an hour so it will be back to saying no signal it’s kind of annoying does anyone know if the series 3 Apple Watch will work with this app without pairing with a phone ?!?
 
Loved it until we Purchased a new phone 
The app runs very well on Apple and older Samsung devices but unfortunately with the new galaxy note 8 we are no longer able to put the application on that device. We have to still carry around the Apple phone and tether it. That has been a challenge due to the fact it disconnects. I’m patiently waiting but it’s getting annoying. Please work on this soon.
 
Disappointed with the Apple Watch interface 
I’ve use the Dexcom app on my iPhone for past 2 plus years and have had no issues. I recently added the Apple Watch and I am disappointed that the interface doesn’t accurately reflect current BS levels. Today I was shopping and started feeling some symptoms but a quick look at my watch showed my levels were 142 and rising. I did not go into the app on my watch until I really started to feel the hypo. The watch face still reflected 142 and rising but when I opened the app, it showed 63 and dropping. If the BS number on my watch face had been correct, I could have treated my drop that much sooner. Please work on getting this fixed!
 
No Longer Dependable - Life Threatening 
I don't know if it's the app, sensor or OS, but the connectivity reliability is extremely poor, particularly when in "Do not disturb" Laet evening, 2/10/18, I fell asleep around 10:30pm and my blood sugar was approximately 135. At this point my blood sugar began to drop. While still asleep, I had a notification at 11:58pm to "Enter BG value." My blood sugar at the time was 82. My body woke me up around 1:40 in a state of extreme hypoglycemia. Fortunately, I have glucose tablets on my nightstand and they may have quite literally just saved my life. I checked my phone which was also on my nightstand approximately 1 and a half feet away and there was "no signal." I left the app open in the foreground until it finally regained contact with the sensor at which point the app read "LOW." It's 2:05am, and as I write this my and my BG is still only 47. I could have quite literally just died while wearing Dexcom sensor without ever having received a "LOW" warning from my phone that was less than 2' away. Its a great tool, but it's life threatening to depend on a Dexcom with an iPhone. I'm going to dig out my dedicated receiver tomorrow and hope for better in the future

Surprisingly terrible 
For how much money this system costs, you should be ASHAMED. The app is horrible. Just dreadful. No export option, changing the graph requires rotation of the device, no range, just alerts. NO WAY TO ENTER LONG ACTING OR SHORT ACTING?!?! Come on!! This is basic stuff here. Also the arrow is almost useless. It only compared it to the last number or something??? If you look there will be an OBVIOUS trend upwards or downwards but because the last measurement wasn’t TOO much higher or lower, the trend arrow says stable even though it’s very obviously not. I’m just hoping this was designed by a non-app developer because then it’s just pathetic, if a developer was involved they should be ashamed of themselves and fired on the spot. Horrible. Needs to be fixed. Update: I BLOCKED YOUR STUPID APPS NOTIFICATIONS AND I STILL GET THE URGENT LOW NOTIFICATION STOP IT

Watch function broken 
Not working on Apple Watch anymore
 
Used to work perfectly 
The app has started to lose signal pretty frequently.
 
Waiting for updates! 
It’s been 4 months since a last update, and I am anxious to finally have this app updated to iOS11. Also hoping to see a stand alone version on the Apple Watch. That being said, I really appreciate this app and use it multiple times every hour.
 
Love my CGM, not this software though 
The obnoxious alerts that CANNOT be silenced or lowered are a huge problem. There are certainly situations where you want to be alerted (if you go low while sleeping) but sitting in a theater and having your phone blast an alert even though it’s silenced is crazy. You should allow users to set sleeping hours. During that time silence/volume settings can be overridden, otherwise they can’t. The other issue I have is with the Apple Watch app. It is incredibly slow to update. How is it that people through Dexcom share have more up to date info than my own app running locally on my watch?
 
this app almost killed me 
whenever i need this app to work most, it doesn't. the connectivity is absolutely awful and about 50% of the time i have the ??? symbol. during the middle of the night while visiting a friend in a dorm, my dexcom was not working, and i woke up with a 36 blood sugar and was 10 minutes away from a seizure and death. if this app had worked like it's supposed to, i would've been alerted at 80, instead of waking up on my own to a 36. it's a lot easier to walk around a dorm complex at 3 am with an 80, as opposed to a 36. if it wasn't for a stranger passing by that gave me some pop and candy, it could have been a scary situation. this device is costly, and often doesn't do it's job. fix it.
 
I wish there was a better alternative. 
I'm so sick of the constant communication dropouts, lack of updates to the software, zero feature enhancements. Sure they'll work with you to replace a sensor, but the whole idea of this system is that it's supposed to monitor you. When it fails to perform its only task, thn that is a concerning problem. What are you doing with the money people spend on this system? It is not cheap. You must have the dumbest developers on the planet or incredibly short sighted management. Hire some real talent. People's lives depend on this. I'm now off to attempt to get a new transmitter because after 3 sensors riddled with dropouts, I'm tired of sticking myself with the huge needles in an attempt to fix this.
 
Dexcom App issues with new IOS update 
Dexcom app has not been reading correctly ever since there was a IOS update to 11.1.1. Receiving the ??? Reading, signal loss and extreme drops and highs. Everything was working perfectly before the IOS update. I find it unreliable at this point.
 
Need update 
Update for iPhone X while you run it in the background the time doesn’t show
 
Seriously? 
For a product that’s changing the medical playing field why is this app such a piece of garbage? For a product that is raking in massive amounts of cash why can’t you hire a team to fix all the glitches that literally EVERYONE is complaining about?

Libre 
Of course the Libre doesn't have non mutable alarms. The Libre doesn't have alarms. Made my choice of Dexcom a true no brainer. I'd rather not die in the night thanks. Once we Medicare patients (red headed stepchildren) can use our phones I will be even happier.
 
Pretty Minimal 
This app works well but doesn’t have simple things that would make it much more helpful. For example there is no way to create free text notes. This would be so helpful to be able to document important life events that may affect Glucose readings. Also while you can document exercise there’s no way to mark other things such as meditation or other common lifestyle interventions. You can’t even document foods or meals! Adding these should not be that hard and would make the app much more user friendly and salient from a health and lifestyle perspective.
 
Was better before update! Very disappointed and upset 
I’m a huge fan of Dexcom, I got my Tandem pump just because I didn’t want to get rid of my dexcom... that being said, when the new updated for the phone and dex came out everything went downhill... now I find myself checking if my dexcom has single 90% of the time instead of me actually having a reading on my app. Very very very upset right now with the quality of the app and dex itself. Like I stated before I specifically got my pump so I didn’t have to switch my dexcom that’s how much I loved it but now im looking into other options like Medtronics sensors or the Free style since 90% of the time my dexcom isn’t working, and for someone who pays out of pocket for the dexcom (nothing covered by insurance) I’m practically throwing 1,000s of dollars away on a device that doesn’t work. If I wasn’t such a huge fan of the dex prior to this whole “no signal” thing I would have rated the quality of I.T now at a 1 star. I’m so disappointed and upset with not only the product but myself that I let myself choose a pump because how much I loved my dexcom.
 
It’s ok 
The complication on my Apple Watch half the time doesn’t show a reading. When I tap on it, it refreshes and shows me something but it would be nice to be able to glance down at my watch for a quick idea of where I’m at. Also, the fact you can’t turn off the audio alert for this app is awe full. The other night it misread my low and continued to beep off and on for an hour. Even though I turned off the audio noise for the app through the notifications, it still goes off. I had half a mind to uninstall the app just so I could sleep without it going crazy for an incorrect reading. I’ll revisit this if these issues can be corrected at some point.
 
Great product needs more flexibility 
I have been a loyal Dexcom patient for several years and I have loved the G4. I have had difficulty adapting to the G5 and have found that this app is not as flexible/ dynamic as the G4 system. I don’t know if the G5 is a sustainable change for me. I have a career that puts me in front of large audiences quite frequently and not being able to control how the Dexcom G5 communicates highs and lows just seems a bit short sighted by the Dexcom team. I hope to continue my relationship with the G5 but there definitely needs to be some updates. We have so little control over so much of our body already - please give us the ability to manage how we are alerted. The whole world doesn’t need to know when I am high. I’d love to see a vibrate followed by a sound feature - I would also love for this to directly connect with my Apple Watch so I can ditch my phone when I take a run.
 
Was great, but cuts out without warning 
My app is enabled in every possible way via Settings. The downside is that the app quits itself (turns off) almost every night! What’s the deal?? I’m thinking of switching to Medtronic CGMS because this app isn’t dependable.
 
Signal Loss 
I have an iPhone and at least twice a day the sensor losses connection. It just started doing this around October 2017. The whole year before that it worked fine. Getting really irritated with this!
 
Repeated audible alerts are fixed 
The app has been vastly improved by an update which removed the repeated alerts and audible alerts even when in silent mode. The app could still use some work on its alerts, but is much better.
 
Make Alerts Silenceable 
Dear Dexcom, Please include an option to turn off or silence the alerts. I am a college student and the alerts are extremely disruptive. Even when I turn off my phone’s volume and put my phone on sleep mode, my phone constantly buzzes. This is extremely inappropriate for when I am in class, in the library, or in a meeting. Please give me back the ability to silence the app. This disturbances are making me less and less inclined to use the dexcom system.
 
This apps works wonders, however it NEEDS A MUTE FUNCTION 
This app is amazing and has helped me control my blood sugar much better. However, I am a student and spend 6 hours of my day in a class room. That being said, this app needs a function where I can mute it’s annoying beeping noises. It’s not necessary that my whole entire class needs to hear these noises. Please implement a mute function.
 
Love ... but have some requests! 
Love this app and Dexcom and their tech support is solid. However, I wish there were a way to customize the app more. Like a fully integrated diabetes tracker. Write what you ate (and not just carb amounts but protein and fat), maybe allow pictures of food, just the ability to add more detail to entries. Like for exercising have weight training or cardio options. Also please get some new alarm sounds! They are all so very annoying, but that could just be me :)
 
Keep loosing signal and no clue on why' 
Frustrating. Getting close to walking away and going to another brand. Was pumped at first with G4, but G5 is making me lose faith. Tired of calling in to get the runaround to different folks and then I finally hang up because of the time wasted. Wished someone could help me trouble shoot this!
 
Dangerous loud sounds 
I am going to get fired or killed because of this app. The alarm sounds are way too loud and can not be adjusted. When this happens while driving it can be terrifying and distracting. If I get in a crash because of this my lawyer will get involved!
 
love my Dexcom, but hate the alerts! 
Love my Dexcom CGM. Love being able to access it on my phone. I’d give a 5 BUT my word - the alerts are incessant, the sound options are limited and deeply irritating, and there are a lack of options to change these settings. At first the alert sounds cause anxiety and then us seasoned users habituate to them due to their overuse. Even closing the app won’t stop you from getting an “app closed” alert every 15 minutes...well it was closed for a reason! While this may be helpful for newbies and kids, us experienced diabetics should be able to control/personalize all alerts, their sounds, and most importantly repetitive frequency. Please work on this, thanks!
 
No control 
This app is really horrible. There is no user control of many functions. Can't set the readings from mg to mmol, no user alarms, no control of muting ALL alarms, scale has only 2 settings, alarms sound repeatedly even after accepting it, no history without connecting online, just simply no user control over important functions and a lack of good functionality for alarms. I too am ready to trash this app and use the receiver. I can dissect it and remove the alarm so it can't sound and use the follow app since I do have control with it. The alarms are really dumb and are annoying instead of helpful. An example. My bs is slightly high and it asks for calibration, which I enter. Within 5 minutes I get an alarm my bs is high. Well duh, i just entered it, knowing it is high and yet I still get the annoying alarm! Another example. I get an urgent low alarm, which I clear and take some carbs. I don’t need an alarm telling me I’m low when my bs is rising from the carbs I ate. We survived all this time without alarms on our syringes and vials! These devices are supposed to ASSIST us, not take over!!
 
It’s a good start but... 
Summary: The app provides basic support for keeping me and my wife informed on our daughter’s blood glucose (BG) readings, but the lack of support for cheaper Android devices and poor UX considerations make the app a pain and unreliable at times. (Critique Source: I am an iOS & Android Mobile App Developer) The good: • transmits BG to subscribers which give me and my wife some comfort through the night as we sleep with our daughter. The bad: • the compatible device list for Android is limited to $300+ Android devices. Our daughter has a $100 Android phone and can’t pair with the app. • sensor can’t be paired with multiple devices. If her sensor is paired with her mom’s device, I would get updates. If she is out with me, no one gets updates because the sensor cannot be paired to more than one device. This limitation actually increases medical risk for a child depending of family device arrangements. • connectivity for sharing user’s glucose measurement may be interrupted and show a red “X”, requiring that ViewController to be presented to start the connection request to be sent to the servers. This can potentially be a deadly issue if this connection glitch occurs in the middle of the night. The good thing is there is an alarm for this, but it should be automatically handled without the user needing to launch a secondary view controller. • on the iPhone 6, my wife tends to get an “Incompatible iOS” message for the companion app. The issue is fixed by closing out the app, terminating the process, then opening up the app again. On my iPhone X, this issue has yet to occur.
 
Very flaky 
Keeps cutting off. Currently, it hasn’t worked at all for the past 2 days. Not sure if it’s related to an iOS update or just sheer usual unreliability of Dexcom. It’s nice when it works, but unfortunately it rarely does.
 
Notifications not working properly after iOS update 
Not getting persistent notifications/status update on my lock screen like I used to with previous iOS version. Also, a laddered (tiered) set of high/very-high blood sugar levels would be appreciated. App not waking me up in middle of the night like it used to with high blood sugars! I miss that.
 
Doesn’t work 
App was fine until maybe October / November .. now it doesn’t work signal loss all the time and whenever it does say start warm up it fails every time waste of time.
 
G5 
My 11yr old daughter is a t1 diabetic and she has the dexcom g5mobile and also she has the t-slim x insulin pump and they did an update on it that u can connect ur dexcom too. The only thing I have to complain about is when I got my daughter a new iPhone 7+ the app will not work on it cause they need to update the software so it will be compatible with ISO11.2
 
For the most part a very good app 
I’ve been using this app for about four months and love it. Is there any way you can fix Bluetooth connectivity? I was four hours without data even w the transmitter less than a foot away. Is there a way you can switch easily between keyboards though? When I calibrate, sometimes I can’t switch from my goofy bitmoji keyboard to the regular one.
 
No phone required...someday? 
Love the app, would love it even more if I could leave my phone at home! I have a series3 Watch, and Dexcom did a keynote with Apple promising a direct sensor > watch connection a year ago. Is it coming?
 
FDA Error in Permitting Insulin Without Glycemic Confirmation 
Some idiots will treat hyperglycemia, on G5, without confirming sugars by blood test. Dexcom heads will roll. Tragedies will result. No Finger-sticks Indeed! The device can't even calibrate accurately. Class actions will follow.
 
Urgent low alarm 
We love this app and the Dexcom for helping manage my sons type 1. The one complaint we have is the inability to silence the urgent low alarm. I understand the thought behind it, but in reality.... I had to choose to shut off his app last night for his concert. So it put him in more danger than being able to decide for ourselves what the best option is for us and our son. Please change the urgent low alarm to be able to be silenced or just put on vibrate. Trying to protect people from missing the alarm is really forcing people to make the decision to have NO eyes on their levels due to meetings and events that we just can’t have it going off in.
 
No Signal 
I am not sure why, but for some reason my iPhone goes off all day that the signal is lost. My cell phone is on a belt clip on my left front pocket my Dexcom Monitor is in my back right pocket 90% of the day but for some reason the cell phone doesn’t ever have a signal. I’ve tried restarting my phone. I have tried installing and uninstalling the app. Nothing seems to work. I like having both because sometimes the Dexcom monitor only vibrates, occasionally it will produce sound. But my phone is loud enough that my co-workers can hear in the case that I have passed out, because that sometimes happens when I go from 110 to 40 in the snap of a finger.
 
Just as bad as using the Dexcom receiver. 
Constantly losing the signal even when the sensor is within 2 feet of the phone. This app never lost the signal in the past. Can’t wait until Medtronic’s supply is back up so I can use their CGM. It’s not an issue with the devices being too far apart or having any interference. My phone and the sensor are never more than 3 feet apart when having signal issues.

Beyond annoyed and ready to toss Dexcom and iPhone out! 
My son has struggled with normalcy for years. He has been T1D eight years now. As he entered middle school we still struggle with balancing school and being a kid with his diabetes care. The CGM was mentioned to us as an idea to try and give us more comfort, more freedom and security with his highs and lows. We did some research and decided to go with Dexcom mobile so he wouldn’t have a lot to carry and it gave me a reason to surprise him with a phone. The excitement once we received the Dexcom was the only excitement a child could have when the situation is related to diabetes. I downloaded the app on his phone and the following app on mine so I could be alerted at night or while he is in the yard playing. The Dexcom and the iPhone will NOT keep a signal. It is always saying signal lost even when it is in his hand. I have called tech support and did troubleshooting but it had not been resolved. So now he has a pump, a Dexcom device, a phone and still a meter because we’re still not sure how we feel about the Dexcom, likely to stop use all together because the point of us getting it was to use with our phones and so I could follow. I have deleted the APPs from our phones because they are worthless. I am beyond frustrated and disappointed! The fact my son was so excited and now completely let down, angers me.
 
Just as bad as using the Dexcom receiver.

Can’t turn off calibration nag message 
Using this iPhone app has always been a frustrating experience. Getting Dexcom to improve the alert system has taken years, now only to be replaced by a nagging message to calibrate the sensor. I sleep with my phone beside me, but the nag message lights up the screen EVERY TEN MINUTES! Do the developers ever bother to use or test their own system??
 
Love my CGM, very disappointed with this app. 
First of all, the app isn’t updated to support the resolution of 6/6 plus and newer. Everything is huge on my 8 plus, this should have been addressed 3 years ago. So many alerts that I cannot silence. Most frustrating are the ones that have nothing to do with my BG. I forgot to calibrate this morning and now I get a notification to calibrate what seems like every other minute. I don’t have my lancet so I won’t test till I’m home and there is no way to turn off all these pointless reminders. Apple Watch complication seems to be working about 10% of the time. High/low alerts keep coming unless I open the app on my phone and tap a notification, even though I have the app on my watch. Really hope some updates address all these issues.
 
Can’t silence an alarm from the watch 
I hate this!! That is so ridiculous that you can’t silence an alarm from your watch. It really feels like the watch is useless when you make us open our phone just to clear an alarm. I thought getting a watch would make my alarms less annoying, but it’s even more so. Now you have to clear 2 alarms, not just one. And why hasn’t there been a Dexcom update?? I haven’t seen one in forever!! Come on, address everyone’s complaints! Update: now, I have spoken to a tech from Dexcom to address my issues. Here’s the kicker, all the settings on my phone and Apple Watch were correct, so the tech is blaming the issue on the new IOS update. But it was messing up even before the update. My watch face has trouble refreshing the new glucose number. Every time I look at my watch face it has 3 dashes (—-), so I have to open up Dexcom on my watch just to refresh the face. Irritating. In addition, I have the series 3, so I know it’s not due to my watch being slow and out of date.
 
Increased signal loss 
After updating my iPhone 6 to iOS 11 I had tons of signal loss if I didn’t actively open the app for any significant amount of time. I upgraded to an iPhone 8 and haven’t dropped signal since.
 
The potential is there. 
Dexcom. You’re teetering greatness if only you utilize the ability to do so. I absolutely love that I can sync with the Apple watches “complications”. But, there’s a tremendous amount of work that needs to be done: Give us the ability to turn on/off alarms! It’s such a basic thing I see companies fail at. Why implement something that a user could potentially not want and force them to use it??? Features: Here we are in 2017. I’m on an IPhone X, which, since not a lot of time has passed so I won’t mention the lack of optimization. But, why does the menu look like it was designed for iOS 6? The menus are rigid, colors are bland. There’s almost no customization of charts. I’d love to color the range I’d like to be in, or to make a graph showing my trend line and why numbers are inside my target and out. Bugs: Watch complication sometimes shows - - instead of reading. Fixes as soon as I click it. Please Dexcom have some innovation with your app as you have your product! Hire another developer to work the kinks and clean up the interface.
 
Please fix the alerts 
Overall I’ve always been really happy with Dexcom. It’s an incredibly innovative product that does what I want it to do. The only issue I have is the alerts. Why do they need to be so loud? If my phone is on vibrate, my phone should do only that. Maybe a feature where the user can set a timeframe where the alerts aren’t so unbearably loud (i.e. not while I’m working)? More than half of the reviews are 1 star. We pay so much to use your product and it seems like you neglect what users want. One would think that, as a company, you would do something to fix this.
 
Used to be great 
Let me first say, Dexcom changed my life. It has made Diabetes far more manageable. But really what is happening now makes it totally unreliable. It seems like every other night I wake to find the app on the latest IOS has just shut down. I relaunch to find data has not been received for the last view hours. Sometimes I’m too low, sometimes I’m too high. The point is, I can’t rely on this anymore. Dexcom, I fear if you don’t fix this issue (just look at the other reviews), then you will begin losing customers. There is competition now. Your product used to be so good. Please fix it.
 
Terrible 
App closes/crashes without ANY warnings, and you will not know until you attempt to check glucose. When you do close the app purposefully (bad sensor insertion, et cetera) and turn bluetooth off, you are inundated with “bluetooth off”/“application closed” warnings continuously popping up on your phone. Terribly executed, and utterly unmaintained.
 
Issues 
I have had nothing but issues with this app and it is the only way I can keep track as I don’t have the external device since I upgraded last year and they knew I had an iPhone. I constantly have signal losses and can’t even connect to my device which means I cannot keep track and have been wasting sensors trying to get it to work. I have a new transmitter and I still can’t get a signal. App must not be compatible with The new Apple updates. Please fix!*****update. Just updated my phone again and everything seems to be ok. This last sensor has lasted 3 days without trouble so far.
 
Slow updates and loud alerts 
Had to restart the Apple Watch to get the app to work in it. The alerts are still not very customizable and very loud when you need the phone to be quiet. You can get def if using Bluetooth headphones (thanks for that!)

Almost ALWAYS “signal loss” 
It always telling me nothing but “signal loss” and sometimes let me know the secret number. What’s the use of this app?
 
New iOS update requires that you download the most version 
The urgent low alarm being mandatory is ridiculous and an absolute pain. I understand why some people might want this feature, but I’m sure that an option could be programmed into the app to activate this feature if desired. Now, the new iOS update has made it impossible to enter blood glucose values on the old version (which doesn’t have a mandatory urgent low alarm). I’m still trying to find a work around, but my opinion of this company’s product is lowering by the minute. I can’t imagine having an urgent low go off in the middle of a day long conference for work. While I’d try to treat the low before that occurs, I really don’t want to be the one who looks like they couldn’t be bothered to turn off alarms on their phone if it takes time for my levels to raise or I don’t catch it in time. I’d basically have to disable my Dexcom for work conferences (making the product worthless). I might start looking into other options.
 
iPhone X 
My transmitter is having issues pairing with my new iPhone X
 
Apple Watch not working 
Check G5 app on your mobile phone. No way to get the watch app to work again. Hope you get it fixed soon.
 
Not Impressed. 
I decided that when I got my dexcom I was going to use my phone as the primary source for my numbers, although now its not a reality. This constantly loses connection, doesnt shkw the same number as read on my receiver, wont met me connect to heath, and its not letting me use share. Its extremely frustrating, there needs to be lots of changes to make this app better.

A great system 
Overall, this is a great system. Glad it’s now Disgnostic quality if calibrated properly. I share some fellow users’ complaints. 1. There is very poor reception if I am playing on our floor (cement with carpet, no metal) with my daughter or sitting on our love seat near a window. No odd signals to interfere in our area. Phone (iPhone 7S) right beside me. 2. The high alerts are troublesome in my office environment, especially in after-lunchtime-meetings. No way to change volume. 3. It is also frustrating to get iOS support notes in the app after even minor iOS updates. Development just has to stay on top of iOS alphas and betas. Should be simple enough.
 
Not smooth with the iOS 11 update 
Hi- please update the Dexcom app so it works better with the iOS update. I have to constantly reopen the app to get a blood sugar reading even when the app is already running in the background. This app needs to be updated so it runs smoother. Please! I really rely on this app and the information that it provides.
 
Needs work 
Definitely helps keep sugar levels in line, but I recently got a new phone since mine broke and my transmitter was paired with it. Cannot connect it to my new phone because of that rendering it totally useless to me.
 
Game changer with room to grow 
My Dexcom has taken 2 full points off my A1C, which I’m very grateful for. The way it pairs with my iPhone and my Apple Watch mean when I get bumps about rises or drops and my blood sugar before they become serious problems, and because it pairs with my devices it tells me that information in a way that fits into my existing life. It’s really nice. That said, sometimes I wonder if they really get input from diabetics when they design some of these products features. I wish they would give me more control over how the Device notifies me. For example, if my blood sugar is dropping precipitously when I’m very high, I don’t care if it’s dropping very quickly. I was in a very somber meeting earlier this week, and my Dexcom screeched at a very embarrassing time to let me know that I had a double down arrow with my blood sugar at 280. That’s totally useless information, and absolutely didn’t warrant the loud notification that it gave me. If, however, my blood sugar was dropping precipitously and I just dropped below 140, then that information would be relevant. Building this kind of logic into the application for me to set should be very straightforward, and would allow me to rely on it’s alerts a lot more. Currently, my solution is to just turn the alert off. Speaking of alerts that I wish I could turn off, there are certain alerts that make noise which really shouldn’t. For example, when the sensor dies and needs to be replaced, or after the two hour period has completed, the Dexcom will make a loud noises when really vibration would be sufficient. That said, the other day my phone Bluetooth function didn’t seem to be working very well in the Dexcom lost signal while I was sleeping. I️ went very hypo and the Dexcom didn’t screech in a situation where it would’ve actually been really useful. That crappy feature put my life at risk. Lastly, I would appreciate the ability to determine which times of day the Dexcom screeches to notify me. Since I don’t sleep during the day, having it screech only at very urgent lows makes more sense than having it screech at all these other different times. However, while I’m sleeping at, say, 3 AM, then I would like to be notified with loud noises about some of the other things like losing the sensor signal for prolonged period of time. This is a good product but frankly I think it could be improved massively by putting more control in my hands, and building in that functionality doesn’t require much work at all.
 
No signal 
This really needs to be fixed. It’s so annoying to constantly have no signal for hours on end. Usually, if I dropped in the night dexcom would alert me but now if I drop in the night I’m kinda on my own because it says no signal for 5 hours every night. PLEASE UPDATE THE APP
 
Can’t silence an alarm from the watch 
I hate this!! That is so ridiculous that you can’t silence an alarm from your watch. It really feels like the watch is useless when you make us open our phone just to clear an alarm. I thought getting a watch would make my alarms less annoying, but it’s even more so. Now you have to clear 2 alarms, not just one. And why hasn’t there been a Dexcom update?? I haven’t seen one in forever!! Come on, address everyone’s complaints!
 
Dexcom 
This app is not perfect but it does most things good enough and does what I need it for. I don’t like the vibrations but I use them instead of beeps. So basically I like it.
 
Gotten worse.....always losing connection 
I used to love this app, now it doesn't work. It will just lose the connection but my Tslim pump will constantly show a reading. I'm not sure what happened but it needs work!
 
Next update 
Please add iPhone X support and make it so we can still silence all notifications if we need to because sometimes I’ll have a false urgent low and my phone starts going off full volume in school even if my ringer is on silent
 
Stops collecting data frequently 
I can't say how often it happens, but at least once or twice a week the app stops collecting data during the night. I'm not an app developer, so I can only guess the reason. Maybe Bluetooth resets. Maybe iOS restarts. Maybe the app reboots. Who knows? I've killed all other apps. I've killed this app and restarted it. Nothing seems to make a difference. So - when I wake up in the morning I need to open the app to make sure it is still collecting data. Everyday. I can't trust that it is working. Intermittent bugs are hard to solve, I know. This does need to be figured out. My life might depend upon it. And yeah - loud alarms that can't be stopped are very annoying. FDA requirements or not.
 
So many things wrong. 
There are so many things I want to say. First, I love Dexcom, well that was until I updated to ios 11. Shame on Dexcom for not being ready for the update. It was a good 3 weeks before the app even paired with my transmitter. And, now that it does all I see is “lost signal.” On top of this all, every time it is working Dexcom pushes an update that blocks your numbers from showing up until you hit a button saying you understand it is in beta. It is not okay to take a functioning product and bring it back into a failing beta because you did not plan for a necessary update. Dexcom is the only app having this issue at the moment. For a company that leads diabetes innovation they are losing customers by the day. Anyone have a better option than Dexcom that works with a tandem pump and my insurance? Times running out to hold onto your customers Dexcom. To all who are looking to use this product. Either don’t update to iOS 11, or if you did, make sure you aren’t relying on this horrible app.
 
Connection issues and phone crashing 
Constantly loosing connection. Have to manually open app on screen. Looses every few minutes. Watch app fails to update a lot. Phone keeps crashing, but if I close Dexcom app completely, phone has no issues. Tech support blamed connection issues on sensor.
 
Could be awesome 
I am so happy with my Dexcom- but this app constantly loses signal. My husband had my Dexcom on his phone to help monitor me as well- but there is always a lost SIGNAL! This app is not for fun- its to help save your life! Please work on this- it's obviously the biggest problem the App has.
 
Doesn’t work with iOS 11 
Hold off to upgrade to iOS 11. It won’t pair with a new transmitter if you need it to. Dexcom hasn’t updated the app to be compatible.
 
I used to love Dexcom. This is a train wreck 
I’ve been on the G4 and now the G5 for about 4 years. The G4 system was rock solid on my iphone and my Apple Watch. Alerts on my Dexcom receiver were reasonable and appropriate. Switching to the G5 was a huge mistake for me. The iphone app throws alerts constantly that cannot be reduced. The constant, nagging, unstoppable alerts render this system a nightmare. Dexcom how could You build such horrible software? If you actively hated diabetics and wanted to make them suffer this would make sense. The Apple Watch app also crashes constantly, this in spite of the G5 app getting called out in the Apple Watch keynote as a showcase app. At night I have to turn off all the alerts on the iphone and plug in a headphone cable in order to get any sleep. Instead I turn on the old school Dexcom receiver and use that for when I sleep. In the morning I have to remember to re-enable alerts on the phone and turn off the receiver which never leaves my bedroom. What a convoluted band-Aid that is. These problems have remained unchanged and unfixed since the day the G5 system rolled out in Sept 2015. Dexcom, you have done a terrible thing and you have let it remain terrible for 2 years and counting at this point.
 
Connectivity 
The app and transmitter have been loosing the connection quite frequently lately. This was upsetting when I woke up to find I did not receive an alert that data was not available and he was over 400.
 
Watch 3 LTE 
Get up to date Dexcom. Watch and Dexcom should connect directly. Ditch the phone.
 
Volume setting for alarms? 
In general dexcom works great. I wouldn’t want to go without it. I agree there could be some app improvements. Many people are complaining about the alarms. I agree more control over alarms or alarm volume would be helpful. Perhaps a volume setting so that even though the silence feature will be overridden (which I appreciate) it will not go to full volume (along with any audio that may be playing). I am also dropping out and losing signal much more often lately. Would also love to dismiss alarms through watch. For reference, I am on IOS 11.0.3. Perhaps this is an issue with the IOS update.
 
Life saver 
Love this app it alerts me when my sugar runs low. I LOVE that it overrides the silent feature. It wakes me at night when i go low. To all the people that complain it overrides the silent feature. CHANGE you high low setting if you don’t want it to make noise in your meetings. I rather make noise and be alive then laying on the floor cause it was silent
 
😁⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ 
I have been a happy and content Dexcom user since March 2016. I am a VERY (try lol) conscience and active type 1 diabetic FYI. There is nothing with the Dexcom system for me to complain about, sure there is the occasional ??? but where would I be without it? Before my dear Dexcom my average finger sticks per day ranged from 6 to 12 one day was 22🙄👆and my average bg level was 95~mg/dl/hba1c 6.1/percent low 27% TWENTY SEVEN PERCENT THAT'S MORE THAN A QUARTER OF MY LIFE AT THAT POINT. OK here comes Dexcom.. Bg average 131mg/dl/ hba1c 6.1/ percent low 3% A PUNY THREE PERCENT... OK you all see where this is going. Fall rate alert- Dexcom: hey boss just sayin if you see some juice have a sip. Me: OK thanks Dexcom. Low alert- Dexcom: just sayin your low. Me: thanks Dexcom for catching that before I am 50mg/dl. I used to carry a fanny pack with glucometer Blablabla, now all I have G5 Mobile on my phone, my insulin pen and an Air head for sugar (in my pocket) To whoever invests time and toil to this cause may God graciously bless you. The questions I call with are efficiently and precisely answered. Your support team gets a definite 5⭐️⭐️⭐️⭐️⭐️ from me. And if I would recommend? Who couldn't guess.
 
The worst experience 
You have taken a process that is supposed to be convenient and made it super stressful and annoying. I stopped using your product because it has interfered so much in my daily life. Not giving your users the ability to control notification sounds is absolutely ridiculous in 2017.
 
Disappointing 
This might be the most disappointing display of corporate neglect I have ever seen. You, dexcom, have the resources and market share to really make a difference and improve so many lives. Instead you have chosen to deliver a sub-par product and have refused to address many of the issues outlined by other users in the community. I hope you find it in yourselves to be more proactive with your mobile offerings and listen to the needs of your users.
 
I loved my Dexcom but it’s not worth anything if it doesn’t work it’s my phone 
Loved my Dexcom used it for about 3 months. Upgraded to iOS 11 and was surprised it worked (even in beta). Transmitter stops working randomly. I purchase a new one. Still doesn’t pair with the phone. I call dexcom several times who’s solution is “do not to upgrade.” This is not a solution and is extremely pathetic considering they have had beta seeds that would allow them to have a working build before an update is released. I would really love this app to work again and work with out me have to worry about updates. Seems like with all the money you’re getting from us you could hire some people to address the issue. Please fix this.
 
Causes nonstop crashing 
Causes phone to lock up and apps to crash. Seems pretty recent, idk if it needs to be optimized with the new iOS update but it makes my phone unusable. Which is a shame. Btw this was tested over multiple new iPhones.
 
Needs improvement 
The IOS update has stopped connectivity. Ran through multiple sensors, all of which have failed. Edit: downloaded xdrip and it’s far better app!
 
TERRIBLE CONNECTION!! 
This app keeps getting worse and worse. It’s constantly telling me that the signal is lost and when I try to restart the sensor I CANNOT! It just keeps repeating “signal loss.” I have to delete the app and redo everything. Not to mention it STILL takes over two hours to warm up (seriously...technology is so much better than this) and at least 30 minutes to pair with Bluetooth. I feel like I’m still in the 90s with this ridiculousness. Dexcom has so much money but yet they can’t seem to invest any in making a proper and useable product.
 
Not usable for adult with a job 
UPDATE/Pro tip: LIBRE DOES NOT HAVE NON MUTABLE ALARMS. TRY IT NOW THANK ME LATER. SOOOO MUCH HAPPIER. Stopped using recently and life has improved for it. Dexcom won't let you silence alarms anymore. You can't use vibrate only on certain alarms either. The problem here is obvious: if you have on, you're always at risk of having a loud, non-silenceable alarm go off at any time. Can't turn off in business meetings. Can't turn off in movies. Alarm repeats every 30 seconds in the loudest volume your iPhone has (loud), even if you’ve already fixed the issue. Even if phone is in silent or do not disturb. No way to silence this in app either. It’s not just alarms for glucose that can’t be silenced. You also can’t silence “critical system alerts” like needing to calibrate or losing connectivity. Absolutely unusable in professional, clerical, or service based job. If you sleep on your stomach CGMs, including dexcom often give false low readings. Again, no way to silence. No way to have vibrate only. Only options are to have it wake you up every 20 seconds or to remove the system. I've gone to a different brand. Much happier. Was good product, but not usable as part of an adult lifestyle.
 
Hidden truths 
It says the app will work right on your smart device. It fails to say however that it does NOT work on the new series 3 apple watch which has cellular capabilities. Apple & Dexcom paired up to make it possible at all to see the CGM readings on your phone. Why are they lagging in the technology for the series 3? Give me a break. If apple has the technology to make the watch, then Dexcom should have it too. Signed an athletic type1 diabetic looking for freedom.
 
Really bad app 
Dexcom has not been successful in implementing a workable app for their CGM. I prefer not to use their monitor because I always have my phone with me. Last time I talked to customer service the surly rep talked down to me. I have a PhD in physiology and did not appreciate the insulting tone. We trust this company with our lives and they seem to have forgotten that very important fact. I assume they fell into the habit of putting their corporate comfort ahead of our satisfaction or safety.
 
Doesn’t work with iOS 11 
When will there be an update for the dexcom app for iOS 11
 
Signal issues 
Prior to iOS 11, this app was great. Some problems with not being able to turn alarms to silent existed... But they were tolerable issues. After updating to iOS 11 the now loses its signal consistently. In a single day I'll have 4-6 dropped signal issues. Other Bluetooth devices I use are not experiencing the same connection issues. Dexcom needs to address this issue promptly.
 
Constantly losing signal.. 
I can have my phone right beside me, in my purse as I walk or on the arm of the couch when I sit and it will say signal loss. This is very disappointing considering how awesome the app and all that it offers. If only I could have signal to utilize all the wonderful features.
 
Needs improvement 
The IOS update has stopped connectivity. Ran through multiple sensors, all of which have failed.
 
The most intrusive piece of software I’ve ever downloaded 
The app works a lot like the receiver the hardware of your iPhone definitely matters in terms of performance. I have the iPhone 8 + which I bought specifically for this software. It’s been working okay the past two weeks with intermittent signal losses. What really pisses me off is the alarms of the signal losses and the high and low blood sugar alarms are completely unable to be turned off. Then when I try to shut the whole thing off because it overrides the sound of my system and buzzes all night keeping me off it alerts me again that the app is closed!!! I got zero sleep last night this made things so much worse. Hire a competent developer team Dexcom Jesus they aren’t that hard to come by.
 
Signal loss issues 
I LOVE my Dex G5 but this signal loss issue needs fixed immediately. I lose signal multiple times a day and it has gotten to where I can't rely on my phone to give me my readings. PLEASE fix so it's compatible with IOS 11.
 
New update 
Ever since the app was updated, the app has to actually be open to hold a signal. Before the update I never had to have it open in the background to keep readings consistently. I’m very disappointed and upset that I did the update.
 
No support for my BRAND NEW Apple Watch Series 3 
The mobile app for Apple Watch says “Check G5 Mobile App on your iPhone” constantly. I quit the app, removed the app(from the watch, then my iPhone), downloaded, signed on to my account. The Dexcom app was then re installed to my watch but when I launch it on the watch face, all I get is that message from above. I’m able to read all my readings and have minimal issues from the iPhone app. BUT I have had to consistently quit the app and disconnect Bluetooth multiple times to keep them in sync. Not happy since the recent update. 😡 The issue persists. 🤦🏻‍♂️Please fix ASAP. Love the product and wish the software worked better. I’ve had diabetes type 1 for almost 20 years and this has helped me manage a LOT better. BUT I NEED THE CONNECTION TO WORK. PLEASEEEEEEEEEE
 
So much promise - such a failure!! 
Guys - please read these reviews and fix these flaws. I love DexCom it has changed my life. But this app is a horrible last mile communication system. 1. Allow the Watch to dismiss an alert, please, please 2. The connectivity is weak. Why can't the iPhone receive maintain better connection to the transmitter? Lots of times I have no information. 3. Why can't the transmitter directly communicate with the Watch. 4. Why are there almost no improvements to the app in 2 years? You are the most valuable diabetes company, worth nearly $7 billion, you have $400 million in cash!!! Please invest a few million of this to improve this app and keep the Company on the leading edge. This app is a poor reflection of the standards of the Company and makes users less confident of the accuracy of your CGM system as a whole. We interact with this dozens of times a day and how the app works impacts the way we feel about the product. Update: IT GOT WORSE!!! The new update has made the app even worse. Connectivity is much worse, alarms are a bigger problem, watch-phone connectivity is worse. You are moving backwards! $400 million in cash, based in California and your development team is third rate. How can that happen? Abbot is coming with a great new device. Get this part of your system fixed.
 
Terrible connection 
The app constantly won’t connect to my iPhone. Signal loss is common. I enter my startup BG but it keeps asking me to enter it but won’t display what I am telling it.
 
Connection issues 
Since the upgrade of IOS software we can only share numbers when connected to WiFi. This has left us with lots of issues while my son is at school and I am unable to see his numbers. Even at home we can’t see numbers if not connected to WiFi. My sons phone has cell service so this shouldn’t be an issue.
 
Signal Loss Issues 
With the new update, the app is constantly losing signal. This happens overnight too which is concerning because I won’t get a blood sugar update. This is why I have the app. My phone isn’t resetting. I am not restarting the phone. I just go to check the app and find it has been offline the whole night. The same thing happens during the day.
 
Love this app! 
I’ve had diabetes for over 10 years and this app and Dexcom System is the most convenient way for me to keep track of my sugar levels. No, the app isn’t perfect, but t gets the job done as it brings me closer to a “normal” life.
 
TERRIBLE CONMECTION 
This app loses signal constantly. This app is supposed to be a medical device accessible to people with diabetes everywhere and it’s not workin properly. When it loses signal for a few hours, I go back into the app to check my connection and it suddenly recalls all the information it lost while it was giving me the “signal loss” alert. This needs to be fixed because I kinda need this to work in order to manage my diabetes. Thanks.
 
Needs to work on watch cellular!!! 
I just upgraded to Apple Watch 3 hoping that I could leave my phone in the car while I take my classes. All my calls and messages work but not my lifeline, Dexcom app! Please initiate an update so that this app can transmit on watch cellular without the phone! Thank you!
 
Upgraded my review 
Time to update my review. Downgraded to 1 star. The latest update breaks the Apple Watch complication feature. The Apple Watch will show the reading, but loses it every few minutes. The only way to get a reading back is to open the app on the watch and wait for it to catch up. It then loses it again. Kinda useless don’t ya think? The darn notifications to enter a calibration are horribly annoying. Yes, we need to calibrate, but there has to be a solution that is less bothersome to the user. Dexcom is rapidly getting competition. The need to get more bugs fixed and release more updates in a rapid fashion. Otherwise, Dexcom may get left in the dust.
 
Decent; needs more features 
Requests: 1) Allow users to separately enter protein, fat, and carbs (not JUST carbs, since we know that protein and fat can also influence blood sugar and insulin sensitivity, meaning they should be accounted for...) 2) Allow different types of insulin to be entered. For example, as a user, I should be able to configure an enum of insulins (Humalog, Humulin R, Levemir, etc.) and select these when inputting doses. Might be helpful to allow the user to add custom insulins, as well, since some people use diluted insulin or have concentrations other than U-100 prescribed... just being able to configure a drop-down with meaningful entries to make the insulins distinguishable on the time series view would be helpful. 3) Allow note entry or integration with 3rd-party meal tracking apps. It would be good if I could either attach an unstructured text document to a meal or bolus event in the app, and see it on later review in the time series view/clarity. Would be awesome to have meal data integration with MyFitnessPal, FatSecret, or other nutrition databases, as well. If you guys can implement any of the above features, I'll pardon the annoyances with the hardware (e.g., the ridiculous startup period, 30 minute initial Bluetooth pairing nonsense, ???...).
 
Needs improvement, but still a good app 
Needs to look at 3rd party cam apps and start to follow their lead in terms of app development and interface capability. The new IOS update has cause my sensors to not connect more than 15mins, even after Bluetooth resets, phone reset etc and even restarting the sensor. Hopefully it’s fixed soon.
 
No improvements 
Still no native Bluetooth support for AppleWatch. Still no landscape mode for iPadd. What the .. are they doing there at DEXCOM?
 
Alert Reminders 
There aren't a whole lot of features but the ones you do have need to work correctly. Although I have my alert not set to remind be for 4 hours it constantly goes of cranking my volume through out all hours of the day. I'd rather not even use the app if it's going to be like this. Fix this please... you provide “features” that don’t even work. The repeat function does whatever the hell it wants. I’m be re-alerted to the same thing every few minutes.
 
Terrible user control options and some important bugs/ glitches 
The dexcom g5 mobile app does the bare minimum and little else, sometimes even less. It is mostly reliable in acting in place of a standard dexcom receiver, and offers extremely basic user control options, however is in need of major improvements, and there haven't been any noticeable changes during the past year I have been using it. My main suggestion for improvement is to give users more flexibility over alerts and settings. For example, I would like to set different alert settings at different times of the day, such as using vibrate during the day and a regular alarm at night. Also, it would be helpful to give more alarms, such as ones multiple alarms for different high blood sugars and lows that can be toggled. This would give me a better understanding of the velocity of my glucose among other benefits. Another minor feature which could potentially make a big difference is by giving user control over the repeat interval of the urgent low alarm. This alarm serves as a safety net for me at night, and it is often difficult to awake after hearing it beep once. It would be an improvement if dexcom allowed the urgent low alarm repeat to be changed so that it can serve its job better. It would also be better if the app eventually included some new smart features, such as predictions and extrapolations from larger data sets, or at least the ability to view older data from the app itself. The other complaint with the app are the bugs which appear somewhat often. App crashes aren't too common, but the main bug that I am experiencing now is that I can't change the repeat setting for the alarms any lower than 15 minutes. Even though options for 5 minutes and 10 minutes are available, when selected, the scrollview shifts back to 15 minutes making it impossible to use 5 or 10. Overall, the G5 app has been extremely helpful in my diabetes management, but can and should be doing a lot more from a software end. Useful features are basically non existent, and significant bugs still haven't been resolved. It is disappointing that Dexcom hasn't been able to improve their software noticeably in a long time, but hopefully they will move in the right direction towards smarter features and more and better (yet still safe) user control.
 
Great to have, but annoying 
Don’t get me wrong, having a CGM and being able to see my reading on my phone is incredible. But having an app that blasts blaring load alerts when I go low or high even though my phone is on silent is obnoxious. It’s so bad that I’m forced to turn my phone off when I go into a theater or any other quiet environment, but then I can’t check my sugar at all. Please fix the obnoxious alerts!
 
Silent alarm (still) needs to return asap 
I need the silent alarm back, this is an achilles heel that will cause me to uninstall the app and look to medtronic. update: Still useless, just end up swiping the app closed and going by feel again. I'm going to guess I'm not alone there. We need the choice to have ugent lows, etc. muted or not. Put a parental lock on it if you must. Update: silent alarm is still broken. To the user with the really long rant, not one bit if that made sense, just leave yours on if you want. I’m sick of needing to swipe the app away when I’ve already treated the low, cgm is lagging behind and I’m in a meeting.
 
My Followers ain't following 
This last update disconnected the followers I have that use the Dexcom Follow app. They aren't able to see my numbers. Shows no data. I re-invited this person and they accepted. The issue persists. 🤦🏻‍♂️Please fix ASAP. Thanks and love the product and support. Will continue to support you. 🙏🏼
 
F****** awesome 😁 
Best thing ever why : this app saved my life. I about died over 15 times and this app told my mum I was high or low
 
Used to be great, now just below meh 
The app used to be co figure or to individual needs. For most adults we don't need a blaring siren deal with a low. We also don't need an alert every 5 minutes until we "acknowledge" by hitting ok in the app. Let me tell you what's awesome. Being in the car, seeing that you're 10 points above your high threshold and getting an alert or vibrate in your pocket every 5 minutes for an hour. Oh sure you could pull your phone out, unlock it, hit ok and try not to crash. Or Dexcom could listen to their customers and give them the ability to customize the alert scheme that they took away in a previous update. Calling the customer support number won't get you anywhere. They've been "listening to customer concerns" and "working on a solution" for more than 6 months.
 
Annoyed by Audible Alerts 
As a college student, there are many times where phone usage is restricted and professors are strict about having the ringers on. After the recent update, the alerts won't shut off when your phone is on silent, which is difficult to explain to professors and disruptive to peers. I love having the ability to see my bg on my phone/reciever in class, I'm just annoyed by not being able to silence alarms. UPDATED: Still sick of audible alarms. The entire school does not need to know when my CGM is ready to be calibrated and this is still a problem. I should not have to strategically plan when to change my CGM based on when I'm in class as to avoid disruptions. It makes me not want to wear the sensor which is dangerous.
 
Alerts are horrible, loud and can't be turned off 
I've reported the issue with not being able to use silent or do not disturb with the app, but Dexcom has said they do not see it as an issue, and do not plan to fix it. It is incredibly embarrassing and rude to have a phone make loud beeping noises during important events like weddings or funerals that you can't turn off. I was able to restore to the previous version of the app that respects silent and do not disturb modes.
 
Just updated now battery drain is horrific! 
Dexcom just messed this app up. Just updated app on iPhone 7 plus and now my battery is draining like crazy! Fix this app now or I'm discontinuing the use of my CGM!
 
It's ok but 
It's ok but I was 55 and 10 minutes later it said 60 it was not helpful when I needed it.

Not compatible with iPhone 7 
I got my iPhone 7 yesterday. I've bee using Dexcom Mobile for several years and love it. Tried to reset password to begin using on new phone and upon opening reset in app I get the message that the iOS is not compatible. Would love to be wrong about this, need help!
 
Life hack for you! 
You know how the app overrides the mute? Well, I have a life hack for you! Get a pair of earbuds, cut off all but the part that goes In your phone, plug it in, and presto! A silencer for when you're in an important business meeting or at school. Literally saves lives.
 
PLEASE change it back so alarms can be silenced! at least on do not disturb.
 
Tslim update 
Hey guys I love this app it have made life with Diabetes so much easier! So I got upgrade for my tsilm X2 and I love it but can you make it so when I calibrate Dexcom on my pump it will calibrate on my phone? Love This app!
 
Frustrating app with unrealized potential 
Used to work great, now it won't stay synced to health for upload load to Glooko a far superior and useful tracking app, alarms are annoying and disruptive it takes time for the sensor to catch up after you make corrections but you still have to deal with alarms, Diabetes doesn't run your life Dexcom does! Signal loss constantly with phone to transmitter, install and wait a half hour for Bluetooth to pair, half hour to pair I don't understand this. All other dexcom apps should be integrated into one app upgrading the functionality of this app would help. Seriously consider looking elsewhere!
 
Still unusable due to always audible alarms 
I simply can't use the latest version of the app because of the inability to silence the alarms. I can't have the phone blaring at me at work during meetings and similar. Recently I was at a funeral in the church when I had a slight low glucose alert - can you imagine if the full volume alarm had gone off then? I'm an adult, let me choose to set my phone to vibrate and decide for myself how to handle it.
 
Small Adjustments Can Make This Great 
There is no doubt that the Dexcom has changed my life & the lives of many other diabetics around the world. This app is a great & unique way to track your blood sugars on something that's already in your pocket or purse all the time, and you don't have to carry a separate device around that is used purely to show you BS readings. With just a few small changes (or at least options) this app could truly be amazing both for what it does & how it does it. First off, the alarms should be an option. They are, to an extent, but the most annoying one for me is the calibration reminder. If you're out, or busy, or driving (which I do a lot), and it goes off or flashes on your screen...it flashes every minute or two (maybe three at the MOST) to let you know you need to complete this task. Even if you just entered a BS number 20 minutes before the alarm is scheduled (12 hrs. after your last calibration) it still notifies you...and it won't stop until you enter in ANOTHER number. Making repeat alarms in general (like a snooze) should be an option. Once I see it I know it needs to be done, I won't forget after three minutes. The Apple Watch app is amazing, and the fact that I can see my numbers all the time without even opening an app is revolutionary to say the least. I can understand that more connection to the app can lower the battery of whatever device it's connecting to, so maybe that's why it often isn't in sync with the app. Click on the reading & it'll update then so that you can get your realtime info. Honestly the biggest thing is the alarms. The sensor stays connected pretty well, and honestly it really has changed my life...and gives my wife & my family peace of mind that they can know if something happens. It would also be great to have all the functions (like reports) in one app but it's not really a big deal. Thanks guys for everything that you do, and I am excited for the G6 when that comes out!
 
This app fails so hard it's laughable 
I don't care what Dexcom's excuse is- the blatant shortcomings and baffling design decisions of this app are far beyond asinine and frustrating as hell. As essentially every other review says, the alerts override your phones silent setting- this is simply unnecessary and unacceptable for the vast of majority of everyday life situations for most people- work, school, the movies, the theater, court, etc etc. Also, the reminder to calibrate the sensor is hardcoded at 5 minutes with no options to change it! I understand that I should re-calibrate every 12 hours, but NO ONE needs a reminder every 5 minutes until you are able to do it! We can't always test our blood sugar at the moment the app asks for it. A single reminder will suffice- we are not mentally challenged! Give us OPTIONS for Christ's sake Dexcom! You are failing!
 
Great app 
So I'm a diabetic and this app is really hepful I go to school so having an Apple Watch is helpful before I got an Apple Watch I had a pebble watch it doesn't have a Dexcom app but because it like all smart watches notifies you it was still helpful with the Apple Watch seeing the trend graph is nice PLEASE allow Apple Watch users to enter numbers from there Watch also here's a LIFE HACK when you don't want it beeping in class or at there air port where they think every thing is a bomb just plug ur earbuds in the beep will just go to the ear buds where no one can hear it thanks for reading
 
More features 
You should be able to search back a months to see you BS level. The app should also give you daily and weekly averages among other things. These are very basic features. Why aren't these included. Dumb.
 
Connection spotty, watch app never up to date 
This app is always having problems. Apart from Dexcom treating PWD as children when it comes to alarm choice, there are two technical issues that are bad enough in the new version that I'm not sure it should be on the market. First, the Bluetooth connection to the transmitter is now much flakier than ever before. I get regular "lost signal" alarms when the phone and sensor are 8-12" apart. I have to kill the app and toggle Bluetooth to get it back. Second, the Apple Watch app (which, when working, is the greatest advance in diabetes care since fast acting insulins) is so often "---" (no data) as to nullify the ambient advantages of having your BG on your wrist. When that number is just a part of the background of your life, it makes managing BG a series of tiny, simple corrections (on a pump). It just melts into the background of life. With the flakiness in recent versions of the app/system this seamlessness is lost and it becomes a burden rather than a helpful tool. I hope this gets fixed, otherwise I'm finally upgrading my pump and using the competitor's CGM because if the connectivity doesn't work right, Dexcom has no advantages.
 
The product is lifesaving the apps are terrible 
The whole product flow of apps for dexcom is amazingly stupid. Need to monitor you blood sugar? Oh you'll need to download the main dexcom G5 app--- oh and it's buggy as hell, you'll need to just reinstall it every so often just to get it to pair to a sensor. Need to share your numbers with needed family and docs? Oh--- you'll need a separate app for that... we call it the share app you'll need that first. Oh--- people that need the data? Yeah, there's a separate app for that too--- it's called follow--- and it to is buggy as hell, we can't really tell you when you'll get your data---maybe you will, eh maybe you won't---don't worry it's your cellular networks fault if you don't. Oh--- your doc needs to see your numbers and trend reports? Oh we've got ANOTHER separate app for that too--- dexcom sensors themselves are amazing in treating diabetes. However dexcom can now claim the title of DEATH BY 1,000 APPS. Integrate people.
 
Awesome CGM - worst app 
Edit: Seriously? The screenshots for the app in the AppStore, they have the normal screen resolution! But in real, they use an old screen resolution, so it looks cheap and not professional. Please guys, 2 months and no update. Come one! Update the app and invest some money to get better and faster updates! To write good critic, I have to be nice and give improvements: - change the screen resolution, they changed it already 4 iOS versions earlier! - sometimes I see my sugar level on the app but not on my Apple Watch? Bug or something else? - sound settings: please let us set the volume of the sound, and not related to the sound settings of the iPhone. Also please let us set something like apple watch vibrate only. - we can set events like sports? Why not food and bolus?
 
Life changer 
I've been using a dexcom CGM for the last 2 years and can safely say that it is the single greatest thing I have done for my diabetes health ever. Compared to using the receiver this app has many advantages. No longer needing to carry the receiver was an immediate win for me. Having the app connect to my Apple Watch was a great addition and I have not had any trouble with the connection on a iPhone 6S and Apple Watch 2. A couple things that could use some help or changes. The inability to mute the urgent alarm signal. I realize that it's probably just a bad idea to mute this audio, but I think there should be a user choice on this. I don't think it deserves the one star reviews that people are giving it for this but it does need an update. Some options might be for a longer delay between acknowledging the alarm. It takes some time for my sugar to raise. The repeated noise just make a bad situation harder to deal with at times. Some new alarm sounds or ability to use my own sounds would be great as well Secondly I would love to be able to update entries. I sometimes enter in the wrong info, and not being able to adjust it can be problematic. Other than that this is a great app and a great system. I look forward to new updates. More apple health integrations for exercise maybe?
 
Calibration Issues 
I was liking this app until the past few weeks when every time I would calibrate, it would require another calibration shortly after causing me to use 2 additional strips per day-- which adds up. If you ignore the notification, it eats up your phone battery with all of the alerts. Trying to get ahold of someone at Dexcom is frustrating with long hold times. Hopefully they pay attention to these reviews, because a fix would be appreciated. Another downside to this app is that there's no way to adjust the volume of the alerts. They are blaring loud (which is great for at night-- but not so great when I'm at work).
 
Volume adjustment please. 
The app is pretty reliable; sometimes the values are off by that's the same for my dexcom monitor as it is in the app. The real issue with the app is that I can't turn the volume down...I keep my phone on me all the time so I can check my sugar, but if I go to 80 it beeps SO loudly and I can't have that when I'm at work. Especially if I'm talking to someone, it just continues to yell at me and if causes a lot of disruption. I can't keep it on my always because it's always yelling, but if I leave it in the office it screams because I'm out of range. The app is just too dang loud!! It needs some sort of mute and volume adjustment- seriously.
 
Best app for diabetics 
I have diabetes in 7 years now I'm ten it's keep working like a boss 😎
 
Don't get me wrong it's a lifesaver ... but 
Latest versions seems to have some stability issues running on a 6s. Occasional freeze etc. LARGEST gripe, like many, is the change that overrides phone vibrate / mute settings. It's really a major pain. I understand the logic that created it - but the implementation is horrible and I suspect largely driven by a liability concern. What about forcing back to full volume after a few alerts are ignored? Or implementing only for urgent low?
 
Great But 
This ap is great, but.... You are turning over your medical information, your ap usage, your blood sugar readings to Dexcom on a continuous basis if you use it. There is no way to opt out of this 'cloud based solution' unless you are willing to never use wifi again. Don't worry however, because via their terms of service: "Dexcom Services are not medical or healthcare services", and - via their 'privacy policy' - they have the right to sell your information to provide you with interest based advertising. Maybe you are happy to give them your data to help them create the statistical models and regressions that could facilitate the creation of a commercially viable artificial pancreas. But maybe you would like the option to just use your iphone as a Dexcom receiver without turning over your personal medical information to third parties.... just a thought. updates now prohibit muting the dexcom ap. so you open your dexcom ap on your watch, phone is silenced in a meeting. still beeps without even opening the phone ap. creepy. this is so annoying. waiting for my new medtronic all-in-one system to be delivered. medtronic let's you set a time for silence and it automatically counts down and unmutes for you. The competitor's solution is simple and slick. Come on dexcom. Tell your programmers to design updates working with user groups. Right now they seem to only listen to tinfoil hat wearing, product liability lawyers. Also, historically you could use an old iphone, leave it by your bed with really loud alerts to wake you up at night. perfect and simple. now they have "improved" the ap and only allow one iphone to link. so much for me and for those of us with a work and personal phone. thanks dexcom. your early app was so much better and more user friendly. congrats- it took real effort to make it this much worse.
 
Quiet? 
Love my Dexcom and the app. Super helpful and fits well in my life. The vibrate setting is good, but it should be an option for the first time calibration. The last two times it has interrupted meetings and interviews by progressively getting louder. Some of us just need it to be silent during the day. There is nothing more obnoxious and embarrassing. Especially when it isn't vital. Also would like this option for urgent lows for the same reasons. I for one am not worried about feeling the low or the vibrate. Would be nice if there were daytime and nighttime alert settings. I want more volume at night than I want during the day. Update: please, please, please make the first calibration alarm stop! I always know, but I don't always have time. Even if I shut the app it still keeps getting louder and louder. Not helpful for a busy professional! I'll deal with it when I can. Diabetes does not run my life! And not being calibrated is not life and death! I love my dexcom, but I can live without it.
 
Get the developer to install mute features. 
This app has a lot of potential and is easy to use with a nice interface that quickly aids in the management of blood sugars. However, the lack of a muted/vibrate alarm makes the app worthless. The alarms are incredibly obnoxious when they go off making the app useless for everyday life at work and school. If you are banking on using this app as an everyday improvement for health management try a different company. Extremely disappointed.
 
Needs improvement, but generally good 
We really could use a "notes" section in our events menu - to help cover or indicate when things happen that are out of the ordinary day to day events, like: "I forgot my insulin here." Or "I was changing from humalog to novolog here (insulin types)" Or any number of scenarios. As one familiar with programming, it wouldn't be too difficult to add a comment or notes section into the app - just a blank space for users to type in comments or reminders to explain their events/results later to a doctor. They might discover trends they didn't know they had otherwise (like repeatedly forgetting insulin, or that a particular glucose profile on their pump was less effective.) All in all, the app is okay. We could really benefit from a notes section in the events menu though! Pretty please with a diabetic friendly sweet on top? :)
 
Can't Mute Anymore- Horrible Design 
Now in class my phone will change its volume to half and beep like a video game when my blood sugar is high. And you cannot silence it. Apple needs to remove this app for messing with iphone functionality until Dexcom wakes up. Edit: 9 months later, still force quitting the app when I am in a meeting or somewhere else important. Totally ridiculous
 
Bad update 
This monitor G5 has soooo much potential. Updated today cause I was hoping for some improvements..but nothing... Please invest time energy & money in to this app..it's the bottleneck to soooo many people having Great health & dexcom being a huge part of that..Bluetooth smartphone & watch working together could change the diabetes game for so many people..please come out with a real Update!!! My phone will say one number..then it takes several minutes before that gets pushed to watch..if it does.. Please please update app to work properly with new iPhone update..sure I'm not the only one who updated phone to now have app keep telling me that it is still working to get app to play fair with phone..it's sensor changing day & now can't get sensor to complete warm up cycle..
 
Hate it 
I keeps losing signal and takes for ever to reconnect
 
best/worst app 
The best app as it is so smart and has been such a life saver - but man o man I get alerts around the clock that the app has crashed (when it hasn't) and it's warning buzzer is so loud, even with my phone on mute, and sends pure evil looks my way from colleagues or people at the movie theatre. Also when you scroll through the app, sideways, it just reverses automatically. If Dexcom put a few app engineers behind these bugs, and reading the comments it seems like a general consensus, it would be a dream.
 
Needs Critical Improvements 
The app on iOS is fine but the UI/UX is ugly and clunky. Developers need to work on this a lot. Perhaps add HealthKit support. The alarm choices are also horrid. Also, this app not available for Samsung Galaxy S8. It's a new, popular phone that's been out for a few months. Please add support! The apps on Android and iOS need a lot of work and improvements.
 
App overrides mute 
I like the fact that this downloads all info to my doctor continuously but even on mute with the volume turned down, this thing alarms loudly-sure it's a lifesaver at night but if I'm in a meeting or out with friends, I can't have it alarming like that with the receiver also alarming and my Apple Watch buzzing. I have to check it frequently and as soon as it gets to 80, I have to turn the phone off. This is very annoying-I deleted the app for awhile but decided to try it again so my doctor gets the info he needs to make treatment decisions that are best for me. Isn't there a way to download the Dexcom info from your computer? I plug in my pump once a week to download-would rather just download the Dexcom that way too.
 
Love it 
But it has flaws & it needs a sleeker design/display. Something easy on the eye
 
Junk 
Always disconnects for no reason alerts going off in the middle of night asking if iv taking certain medications. This is junk nothing but problems. Regret ever getting the g5.
 
Alert Reminders 
There aren't a whole lot of features but the ones you do have need to work correctly. Although I have my alert not set to remind be for 4 hours it constantly goes of cranking my volume through out all hours of the day. I'd rather not even use the app if it's going to be like this.
 
Alarms 
i am starting to get used to all of the alarms so they wont wake me up anymore please add more!!!
 
Last update has issues 
I recently got a new phone (went from a 5 to a 7, love it btw). However, I had to delete and reinstall this app. This update has some issues that need fixing. I personally have no problem with the audible alarms, but I wear my phone on a belt clip, so I get to it when it vibrates most of the time. My biggest issue has been with inputting my blood sugar for the calibrations. 2 days ago, it wouldn't accept the reading, then yesterday it was fine for both checks. This morning, I entered in my morning check, and about 2 hours later it started asking for another meter value. This is a serious problem that I'd never dealt with prior to this update, since I'm not even sure if it's calibrating off those readings or not. This needs to get fixed or else I'll be forced to abandon the app and add another piece of technology to carry around with me.
 
Mute 
Give us a mute button please
 
Does not obey notification sound settings 
Delivers repeated audible alerts that cannot be disabled or dismissed reliably. Fine app otherwise, this makes it probably unusable if you know, have a job or something. I'm sure that this was an FDA requirement to have the audio alerts- I am a physician and would be happy to work on lobbying the FDA to change their standards for these devices. I have asked dexcom engineers and employees a number of times if I could be of assistance with this with no results. Currently, I'm using the ~September 2016 version of the app as a workaround, but this will not work forever and I'm hoping that someone, if not me, can help change the app for people who have jobs or are in school. Other diabetic physicians that I know turn it off while at work because of this 'feature', please help us find a pathway to having the standard change.
 
Connection 
It keeps saying transmitter not found even if I'm right next to my phone and haven't done anything. Wouldn't recommend.
 
Do not update if you use Apple Watch 
This update breaks the Apple Watch complication! It also doesn't provide any enhancements or fixes. Dexcom really should test their apps for core functionality before release; that's just software development 101... Do not update!
 
Mute. 
Cmon dexcom. You know what to do.
 
Apple Watch complication great, loud alarms still a problem 
I am so pleased by the Apple Watch complication in the latest update! I hope the watch app will now allow alerts to be dismissed without having to open the app on my phone, but it's not clear if that's the case. Unfortunately it doesn't seem that the issue with the audible alarms has been solved so I have left my previous review below. Thanks for the update, keep them coming!! - The latest update has disabled the ability to silence the app, unless you specifically set each alarm to vibrate only (except for Urgent Low alerts, which are audible no matter what). Before the update I would set my phone to vibrate or Do Not Disturb while at work (or anywhere else I need my phone to not make noise) and turn the silent switch off at home so that I can hear the alarms at night. Now, no matter what sound settings I put my phone on, there are LOUD blaring alarms. Because of this I've set all the alerts to vibrate only, and now the dexcom no longer does me any good at night. PLEASE dexcom, this update makes the app nearly unusable when the alerts worked well before- please fix this!!!
 
Inventive concept - however, needs work 
I have only been a user for a week, and so far it has done well what I wanted it to do... help me keep closer tabs on my BG and stop high situations sooner. However, I agree with the rest is of the reviews, there needs to be a mute feature. I too can't have my phone making such disruptive noises when I am in meetings or leading conf calls. Additionally, all the documentation and tutorials say that the sensor is water resistant up to 4m and will continue to monitor but the receiver (or phone) has to be closer. I have yet to actually experience it working. As soon as it gets wet (like taking a shower) I lose signal and it takes up to 20 min to reconnect
 
Add a mute or vibrate feature! 
As much as I love my Dexcom, I hate that the app blares an alarm when I'm low. When at work or in college classes, I need to be able to silence the alarms or have a vibrate mode. I do not want to have to turn my phone off so the alarms don't go off and be blind to what my glucose levels are.
 
HATE THE UPGRADE 
Can't silence the alerts before I go to meetings. Can't silence alerts at night. App freezes every time you get an alert. You get multiple unsilenceable alerts for each event. What idiot thought this would be an improvement. 7-19-17 Update: NEED To BE ABLE TO SILENCE ALERTS!!!
 
Priority Request: Mute 
After correcting for low blood sugar the device won't stop beeping! This device is useless until this flaw is corrected. I'm switching over to Medtronic until you guys fix this!
 
Please change alarm settings! 
Like a lot of other users, I hope that Dexcom changes its alarm system. It would be awesome if you could set the alarm by time, so that if you're in class or at work the alarm would only vibrate but at home and at night it would be an audible alarm.
 
Great app, minor tweaks 
I'm going into high school, and have used this for two years. It has helped me SO MUCH. Especially in the night, when I wouldn't have woken up just from feeling weird. I just have two changes I'd like. 1) Customizable alarms. All the alarm sounds are loud and obnoxious, and there are some moment when they have overridden the silencing of my phone. Somebody needs to give us more nice options, so it just sounds like I'm being called. 2) Repeated lows. I don't know how to fix this, but it's definitely annoying. When I go super low, (50-60), it starts telling me it's urgent, and stays urgent for up to an hour. Usually, after I check after 15 min on my meter, I'm in perfectly normal range, or high bc I thought I was lower than normal. Other than those things, though, this app is useful and amazing for a FREE MEDICAL APP. If you're hesitating bc of all these reviews for this, don't. It's more useful than annoying.
 
Great...when it doesn't lose signal 
I could LOVE this app, but it seems to lose the signal many times during the day. The app tells me it loses the signal when the two devices are too far away from each other (i.e. the transmitter and iPhone or Apple Watch). Well, my phone is seldom more than a few feet away from me, and my Apple Watch is NEVER any more than 2 feet from me while charging at night. Other than that, it is on its on my wrist. It is frustrating when both my iPhone says "lost signal" and Apple Watch shows "--" throughout the day. If that problem could be fixed I would give it 5 stars. While typing this review I got a notification that the app had lost the signal. Sigh. Not surprised.
 
Works, but lacks customization and interface limited 
The Dexcom CGM works well, and it's a minor miracle that I can monitor my BG on my phone. The app is dependable, but would be more appealing with added customization. Alarms -- As others have pointed out, users have little control over urgent alarms. I greatly appreciate being awoken before my BG gets too low, but once I've had my bowl of cereal, I just want to go back to bed, not muffle my phone under my pillow until my BG stabilizes. How about a "Silence all alarms for 30 minutes" button? I would even check a box acknowledging the increased risk. Perhaps password-lock this feature for parents? Events--I would like to be able to record nonstandard events which affect BG, like drinking coffee, or that I set a temporary basal on my insulin pump. Graph--Lacks IOS-standard zoom and pan features. Overall, I highly recommend the Dexcom CGM, but if you intend to pair it with the app, be aware that alarm management is going to be a challenge.
 
I thought the app would make life better 
I can't even open the app! Argh!!! This stinks beyond words!!!
 
Was an amazing product. 
This was once an amazing app as it helped get my sugar under control. Now with the mute override feature, I am no longer able to use my dexcom. Instead of paying attention to my work I would have to watch my sugar like a hawk to prevent it from triggering an alert that doesn't follow my silent or DND preferences. Edit: App was updated of 7/14. Add of this update my phone preferences are still ignored and I am not able to completely silence my phone.
 
Come on! Give us a mute button! 
3rd review and the #1 requested fix is still not done. It must be the users choice to have alerts for all cases. It's on the user to decide what is important. At no time did my glucose meter jump at me because I hadn't made a test in the last 5 hours. This app should be a tool utilized by the user as they see fit. Give us control of all the alerts! 2nd review: 1 star I love that after countless reviews with a 1 star you guys don't even acknowledge the urgent low sound cannot be disabled on the last update. Give me a break. I understand this might be forced by the FDA, but I thought the FDA approved system was the separate receiver; why can't this app conform to the users requests?!! 1st review: 1 star Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
No mute option 
The app overrides silent mode to maximize volume, alerting everyone in the room with a loud beep. This "feature" can't be disabled. I used to really love this app. But like most adults, I'm in situations where I absolutely cannot have my phone making noises. I hate how I have to constantly worry about my phone making a loud beep. Often I close the app, which means I won't be able to see the data, but I least I don't have to worry about a potential alarm. Please, Dexcom: we need a mute option!
 
Great product- major flaw! 
I love my Dexcom and how easy it is for me to check my levels whenever I need rather than poking my finger every time. What I don't love is the lack of a mute feature.. I'm in college and I don't always turn off my phone in class (sometimes it's needed for research rather than lugging around a laptop). If I have a low or high glucose alarm the only way I can stop it from beeping at me is to turn off my phone! I correct as soon as needed but it can sometimes take a little while for my body to respond- so even though I've taken the proper steps to resolve the issue I can't stop being a disruption to class or wherever I am at the time. There needs to be a mute option.
 
Needs mute 
Does my fingerstick meter yell at me when my levels drop below 65? Of course not. We're all adults here. Please treat us accordingly. OTHER THAN THAT THIS A FIVE STAR, REVOLUTIONARY APP
 
Bad update 
This monitor G5 has soooo much potential. Updated today cause I was hoping for some improvements..but nothing... Please invest time energy & money in to this app..it's the bottleneck to soooo many people having Great health & dexcom being a huge part of that..Bluetooth smartphone & watch working together could change the diabetes game for so many people..please come out with a real Update!!! My phone will say one number..then it takes several minutes before that gets pushed to watch..if it does..
 
Apple Watch complication great, loud alarms still a problem 
Recently the Apple Watch complication remains blank and when I open the app on my watch it will zoom through the graph to catch up to the present. It didn't used to do this, hope it's fixed soon! ------- I am so pleased by the Apple Watch complication in the latest update! I hope the watch app will now allow alerts to be dismissed without having to open the app on my phone, but it's not clear if that's the case. Unfortunately it doesn't seem that the issue with the audible alarms has been solved so I have left my previous review below. Thanks for the update, keep them coming!! - The latest update has disabled the ability to silence the app, unless you specifically set each alarm to vibrate only (except for Urgent Low alerts, which are audible no matter what). Before the update I would set my phone to vibrate or Do Not Disturb while at work (or anywhere else I need my phone to not make noise) and turn the silent switch off at home so that I can hear the alarms at night. Now, no matter what sound settings I put my phone on, there are LOUD blaring alarms. Because of this I've set all the alerts to vibrate only, and now the dexcom no longer does me any good at night. PLEASE dexcom, this update makes the app nearly unusable when the alerts worked well before- please fix this!!!
 
Where's the mute button? 
I can't have my audible alarm going off in the middle of work. Please add a mute button asap!!! I shut my phone off to prevent my glucose monitor from alerting me. Also the volume level of Dexcom's alerts are crazy loud when I have headphones on. Please make the device alert at the same volume settings as the headphones, not ear-drum-bursting-loud at all times!!
 
Poor Connectivity 
When the product works, it works great. However, it only works 1/5 of the time, in my experience. Signal loss issues happen far too frequently.
 
Love the freedom of not needing another device. Hate the alarm configurations. 
I LOVE having the Dexcom G5. It's made my life a ton easier and I love how I can simply look at my Apple Watch to see my blood sugar. What I can't stand though is the alarms and alerts. I'm a movie guy so I'm at the theater a lot. When you're eating popcorn at the theater there's a good chance your sugar will go up and if you take insulin in advance there's a good chance it'll go down. I've had this thing go off in the middle of a movie before even when the phone was in do not disturb mode and was set to silent. The only way to shut it up is to open the app to show you've seen the alert. I'd love it if you could do that directly on the watch instead so I wouldn't have to pull out my phone plus my watch just taps me so I don't have to deal with those ridiculous alarm sounds. What I have to do now is turn off high and low alerts when I go to a movie but urgent lows can't be turned off and I'll forget to switch them back on after the movie is done sometimes which can become a problem. Going back to the alerts is another issue which I touched on a bit already is being able to stop getting a notification without using the phone's app. I work outdoors a good bit and I love having my Apple Watch for that very reason so I don't have to pull out my phone for all the notifications I get but with this I get a notification every 5 minutes if my sugar is high or low. I want to be able to silence those directly from the Watch because I'm working and can't pull out my phone at that moment but I see the alert. It gets very frustrating to acknowledge the alert and have my wrist tapped every 5 minutes when I can't do anything about until I get done with what I'm currently doing. It looks like a bunch of these issues can be resolved with the updates coming with WatchOS 4 in a few months which will have the G5 communicate directly with the Watch 🙌🏻🙌🏻 which is some of the best news I've heard. Hopefully these will all be resolved soon.
 
Great app, and amazing CGM! 
Love it! Works like a charm, doesn't drain battery. The low star rating for "can't turn off alarms" is incorrect. You can turn all alarms off except for the URGENT LOW. That's where your cgm is trying to save your life because you have entered a level below 55. Seems logical to me. The receiver would do the same exact thing so this is no different.
 
Volume control kills it, in a bad way 
Volume is not controlled by the iPhone volume controls at all. You either have vibrate or obnoxiously loud for high warning, and ONLY obnoxiously loud for low warning. Horrible for public situations such as work, church, movie theater, etc. What were they thinking?!? You used to have normal control in older versions. Otherwise, the app seems to be slightly improved on actual reading values when compared to actual meter values, but that's probably due to sensor improvement. Agree with most everyone else - please put volume control back to the phone!
 
Awesome CGM - worst app 
To write good critic, I have to be nice and give improvements: - change the screen resolution, they changed it already 4 iOS versions earlier! - sometimes I see my sugar level on the app but not on my Apple Watch? Bug or something else? - sound settings: please let us set the volume of the sound, and not related to the sound settings of the iPhone. Also please let us set something like apple watch vibrate only. - we can set events like sports? Why not food and bolus?
 
Bluetooth issues 
I've used this app a couple of months and have high expectations for it. But currently the Bluetooth is totally unreliable. It drops connection constantly then states it can't find the device. I would have returned the Dexcom if not for the handheld receiver which is very reliable. Update: after I got my Apple Watch I stopped using the dexcom receiver. Once I stopped using the dexcom receiver I've had almost no Bluetooth issues with the app. New issue: when will we be able to adjust notification timing and sound? I get pinged every 5 minutes no matter how I change settings.
 
Great CGM terrible app 
Alarms that wake the dead with no way to adjust or mute, constantly losing connectivity even when at bedside, alarms that constantly blast every few minutes even though you have cleared them. I really want to like the app and not have to carry around another diabetic thing but i really hate the app. Since i'm up at 3am thanks to the extremely loud alarm for a correction i made a while ago... i think it's getting deleted after this.
 
DO NOT GET UPDATE 
I have always loved Dexcom and have been super impressed with its amazing ability to help me manage my diabetes! However, the recent update doesn't allow me to silence the alarms! It is as if I am a child that needs constant reminding to check myself! I am very responsible and check my numbers all of the time. I understand the concern maybe for younger people but there should be the option to over ride this or customize my own sounds! The lowest I can put it on is vibrate which is still disruptive. What if I am at a show or a movie? I now have to be constantly concerned that my phone will go off and disturb the people around me. Now I feel as if I have to turn my phone completely off so as not to bother people around me as well as myself! Which of course is not good because I should be able to constantly monitor myself at my own comfort. This is a bad way to help users because now I am stuck with a phone that CAN NEVER BE SILENCED! But I can't just delete the app because I can hardly go back to pricking myself 10 times a day!!!!!
 
App keeps giving error messages 
App alarm keeps going off every 30 minutes and a message pops up saying exit and re-open. Please fix!
 
I Rarely Bother Writing Reviews but I Made an Exception 
The beeping-> unacceptable and intolerable for people that are in any professional setting or are even just trying to sleep The Interface-> Archaic, one would think Dexcom would update their app with anything other than minor bug fixes every blue moon, doesn't look good, isn't easy to navigate, and barely shows me the data I want to see Sharing-> Inconsistent and unreliable for anyone trying to forward information to their provider or parent I got this monitor because I didn't want to carry an ugly little black cube around with me and all the diabetes supplies along with it, but here I am
 
No Configurability & Overly Loud Alerts 
I love my CGM, but honestly this app is making me consider ditching Dexcom as a whole. While wearing a CGM used to make you feel more free as a diabetic, this app takes freedom away from you. You cannot silence the alarms, and you cannot let the app know that the solution that it is alerting you of is currently in progress to be fixed. Because of this I no longer feel comfortable going to movie theaters, staying the night at other people's houses, or doing anything that won't be ruined with the most unpredictable and thoughtless alarm programming in a mobile device. Even deactivating the sensor and completely closing the app won't do anything. It will still blare an un-silencable alarm every couple of minutes, even when the app is not running and you are not currently in a session with your CGM. Also, setting the alerts for vibrate doesn't actually turn off the obnoxiously loud alarm sounding along with it, and the app won't push alerts to your Apple Watch so that you're the only one who gets notified when something happens. Even while wearing my Watch, the loudest alarm that you will ever hear will still blast through your phone with absolutely nothing you can do about it but sit and listen to it. Dexcom steals your freedom with this app and I have never felt worse about being a diabetic than when I am using this Dexcom app. I am done with Dexcom as a company until they can put more control in the user's hands. It is truly that bad.
 
App never works 
This app never works with my sensor. It is always saying signal lost when I have service on my phone. It's not worth having the app. The Dexcom receiver does just fine.
 
Dangerous 
Still no fix for the 'Silent' function. Reporting to Apple as a violation of App Store Software Agreement 2.5.9: "Apps that alter or disable functions of standard switches, such as the Volume Up/Down and Ring/Silent switches, or other native user interface elements or behaviors will be rejected."
 
Need edit function 
It just does very basic work. Hope I can fix typo or wrong information I input.
 
Good app when it works 
I've been using this app for most of this year. Last week, I replaced my iPhone 6 with a new one, and after restoring from a backup, the Dexcom app is crashing every 5 to 30 minutes. The only way now for me to get continuous glucose readings is to manually kill and restart the app about 20 times a day. I really hope they fix this soon.
 
Drops Bluetooth connection 
Works great when it works, but current version drops Bluetooth connection a few times a day, and I've got to futz around to get it to work again.
 
I love my dexcom, but this version crashes every few minutes 
Since I installed the new version, this app crashes constantly. It makes a ridiculously loud beeping noise with a notification that says exit app and restart. Very frustrating
 
Please listen to the customers 
I feel bad that I have to give this app such a low rating, because I genuinely appreciate having it. Using a CGM with info available on my phone and Apple Watch is a great set-up. But I want to add to the chorus of complaints about volume settings: this app is so frustrating because it acts like customers are deaf and can't be trusted to manage alerts how they want to. I totally understand that with a medical product you have to design for the least capable users, but AT LEAST put in customizable settings for those of us who can make the decision to alter notification styles. The lack of a true mute is terrible. As many have said, I simply cannot have a ridiculously loud warning siren going off in a professional setting. Dexcom, please listen to your customers and add this important feature!!!
 
Great App; One suggestion 
Having the app has been a huge help. My one suggestion is to have the arrow on the apps square face that is clicked on to open the app move, the same way it does inside the app (the apple clock app does something like this).
 
Not connected 
The app is not very reliable. I have had the dexcom for a month now and the app will read not connected off and on all day. I replaced the phone and still have issues to where I have to reboot the phone stop/start my bluetooth and hope it comes back on. The chargeable transmitter is more reliable but I keep that at home next to the bed.
 
Nice to have, but CONSTANTLY crashes 
I love not having to tote around a receiver for my CGM. In that respect, the app is great. But there are several issues: 1. Volume. The alerts have no silence feature and generally seem to do whatever they want regardless of your wishes. 2. The app constantly crashes. I've an older phone (5C), so maybe that's a factor, but I'd say the app crashes at least 50% of the time.
 
Fix! 
I like the app, I just wish there was a way to silence or fix so I don't have to restart to app. It is very frustrating!
 
Please improve the user experience and analytics! 
Great to have CGM on my phone, BUT the app could be soooo much better. Frankly it's awful. Perhaps there are regulatory restrictions which make changing the code etc. very slow and hard work, but Abbott has managed to do a much much better job of their app for their Freestyle Libre Flash Monitor system (only available in Europe at the moment). Their's is way more informative with many different types of graph and historical analysis, which provides a much nicer user experience, and supports proactive glucose management much better. Looking forward to future improvements...
 
Good, but it could be great. 
It is great to not have to carry an extra device. You do have to manage your phone's battery with care as it is now your glucose information source but there is nothing Dexcom can fix there. I also find having my CGM readings on my Apple Watch incredibly useful. I can check my CGM reading much more discreetly than I can on my iPhone or the receiver. Read on to find out why it doesn't get 5 stars. I want the app to honor "Do not disturb" mode on my phone, or at least make it an option. I use the receiver rather than the phone at night and if the receiver sounds an alarm I have to cancel it on both the receiver AND the phone. I want the app to look and behave more like an iOS app. It looks like an app built with a "universal" framework to create iOS and Android apps at the same time. The alerts are odd looking (they don't look like other iOS alerts) and cannot be dismissed from the notification, you have to launch the app to dismiss the alert. Please let me dismiss it quickly so I can deal with the problem that caused the alert. When I dismis an alarm on my watch it should be dismissed it on the phone too, but it isn't. I understand that the receiver and phone don't talk to each other and that is why I have to cancel the alert on both, but the watch and the phone do communicate and this is possible and needed. The second alert is loud and inappropriate in some environments and completely unecessary when I have already acknowledged the alert on my watch and taken steps to address it. On the Apple Watch, why are there Dexcom complications only for the modular watch face? I want to add my CGM readings to ANY watch face, not just the modular one. Barring that, it would be better to have a simple icon complication on the watch that takes you to the Dexcom app with a tap rather than have nothing available at all. I have complications on other watch faces that include both a number and an icon, so it is certainly possible, I don't understand why Dexcom didn't create those. Despite all this it is incredibly useful to have the CGM deliver information to my iPhone and my Apple Watch, and I will continue to use it.
 
Miserable app, dont use 
The CGM itself is great but the alarms are absolutely atrocious. Whoever programmed this app needs to be fired. There is no way to silence the low or high alarms, or even set them to vibrate instead of heinously loud noises. And the sensor gives you a reading that is about 10-12 minutes behind what your glucose actually is. This is to be expected, but this means that if you test your sugar and see you are 60, when your CGM reads 88, and you correct with a snack, then you are still doomed to hear the miserable alarm for the next 15 minutes despite you already correcting. Im discontinuing my use of this CGM because the app treats us like children. Unbelievably easy thing to fix and they just won't put the time or effort into GIVING US THE OPTION TO SILENCE ALARMS.
 
The app is good but could be much better 
I love my Dexcom G5 and find the app to be useful and simple. Yes, it would be great if a person could silence the alarms but that might be seen as defeating the the purpose of the device. If the alarms are a serious issue for you, set them much higher and lower than you generally go and that should help the situation. If you do that, it's really not an issue anymore. Just remember to change them back when you need them. All in all, I'm very happy with this app and see it is quite a lifesaver.
 
Treats me like a child 
This app forces a multitude of alarms on me and I am unable to silence them without force quoting the app entirely - preventing me from seeing my numbers on my phone. The addition of this "feature" has significantly worsened my diabetes control because I am required to turn off the app for a large portion of each day. As an adult, I should be able to decide when and if I want to be alerted.
 
Love it! 
I suspect a lot of the complaints are about rules imposed by the FDA. But even if they aren't, the dexcom app on my phone (and more importantly, on my watch!) has been downright liberating. Thank you Dexcom for continuing to improve the app.
 
I stopped wearing my sensors, the noise! 
The noise cant be turned off, makes full Volume sounds if high or low blood sugars but even when volume completely off and vibrate on. Used dexcom for 3 years until now. Also, why recommend the dexcom receiver if the reason i got g5 was for phone Bluetooth and the transmitter i wear is larger for that feature. Sorry for rant but its been months!
 
LET US CONTROL OUR LIVES 
If this App is going to deliver on the promise of glucose monitoring then it has to let users decide on volume and sound control. Please fix the App so that it stops overriding the silent mode on the phone. This needs to be fixed NOW!!!
 
Perfect? No. Useful? Yes 
I saw all the negative reviews and felt I needed to leave my two cents. No, the app is not perfect. However, it's much better than having to carry my PDM (use OmniPod), phone and a separate remote for my CGM. The most recent update has made a lot of improvements, including low glucose alarms even when on silent mode. I know some users don't like that but overnight when my phone is in silent mode I find it useful. Also with the latest update the alarms are much more customizable, so my app only makes actual noise when I have an urgent low glucose alarm. Otherwise it's vibrate all the way, and I love that. Overall, I prefer it to having to carry a separate device.
 
All it does is lose signal 
It seems like I spend more time trying to reconnect my signal than anything. Even though I carry my phone with me everywhere.
 
Can't live without it! 
This is the best app ever for a type 1. I feel so great knowing my blood sugars at all times, and the alarms keep me safe at night/driving/at work etc. The convenience of having it on the phone really helps!!! I don't understand the negative reviews....as a t1d who has had it since age 3 (I'm 36 now), this has been the best item/change to come along in this lifetime!!!!!
 
Cannot find receiver 
Lost signal at 3 am. Now it can't find transmitter to pair with. App is useless, again.
 
No Clue Why The Hate!?? 
People are nuts. This app and device is a life saver. People leaving 1 star because of the alarms. Just don't use the alarm and look at it every once and a while. Set the alarm to something very high and very low. If you have lows then you want the alarm! It works great for me. Why would you want to bring the device with you when you can use this! Thank you Dexcom for making this awesome device and app!!
 
It's all you need 
I have been a Dexcom user for a few years now and was so relieved when I upgraded to the G5 system, mainly because I could use my phone rather than a separate device to check my blood sugar. I dont know why there are so many negative reviews about this app. It gets the job done, no more no less. Sure, sometimes the alarms can be annoying when your glucose is hovering around your upper/lower limits, but I keep my alarms on vibrate and they never bother me. The urgent low glucose alarm will bypass the "vibrate only" alarm and will scream at you if your volume is up, but the convenience of this app outweighs any and all shortcomings. This app is wonderful. I depend on it and I am happy with it!
 
Dexcom 
Always have to continually reconnect with phone. If the CGM and phone are not within 2' of each other, they do not stay connected. Dexcom charges $2000 for a device with the year 2000 Bluetooth technology.
 
V.1.71 not compatible with iOS 10.3.1 
After installing this app and running full time continues to cause lockups and hard freezes that require home power button combination to reset the phone. Have a backup phone for safety when using this app 24/7/365 as it is not stable. :(
 
I bought an iPhone for the app 
I do t regret buying an iPhone for the app, but the app should allow you to adjust the urgent low alarms to be more frequent if you want. I u understand not being able to make it less frequent but let me make it more frequent. Also let me have an option to make it vibrate or have the sound on with the flick of a switch. I would love to be able to switch between sound and vibrate by pushing a button in the app. This would make the last update for the app event more useful. You guys are doing a great job with the app! Thank you for all you are doing you are making managing my diabetes much better!!! I also love that when I lose the signal for some reason, the app catches up my numbers so I don't lose any data. This was great!
 
Upgraded my review 
I am a physician and prescribe the Dexcom, and I am also a patient using it. Like many others, I was furious at the update that overrides the mute button. After a while, I realized several things: 1) This was most likely mandated by the FDA, or done to get the FDA off their backs. If that is the reason why, than I am still grateful they got this out to us. 2) if you are in a meeting or at school, and have Urgent Low, you probably should not be there. Your mind would not be functioning correctly and you are actively damaging brain cells. Treat your low blood sugar. Yes, it takes time for the correction to display. Until then, just PUT YOUR PHONE IN AIRPLANE MODE. Turn it back on when you leave the meeting. You should be watching and be prepared for this anyway. If you are not a frequent watcher, turn on a vibrate alert for "Fall Rate", so you get warned way ahead of time. Easy! Next, there was one IDIOT here who left a review about how inaccurate the Dexom is. At the same time, he admitted that he does not calibrate it correctly! What a dumba$$!! The Dexcom does not sense and calculate a sugar on it's own. It must be calibrated to work. Now, calibration alerts are something that needs improvement. I get the need for alerts to calibrate, but every 5 minutes from the get-go? Just annoying. Probably a requirement, but I have a work around: Notify us 15 minutes early, then wait 20 minutes. This second warning will only be 5 minutes late then. Then, maybe a little leeway, and wait another 10 minutes a couple of times, then every 5 minutes. If we don't calibrate after 1 hour, send a warning message. Anyway, the G6 will only need 1 calibration a day, so that will be nice and this will not be as needed of an improvement.
 
Can't silence low alarm 
Screams at you (for lows) without any ability to silence it. Extremely frustrating at times. Also calibration alerts are constantly distracting me. Dexcom, please make these alerts optional. Jfc.
 
Fix Please! 
This is a great app and feature to improve blood sugar control and concurrently your a1c. The problem is it keeps glitching and needs to be restarted every 30 minutes and is not possible to turn off. Please fix this Dexcom. It worked great before. The feature to see your overall graph on your iPhone and pair it up with your drs office is so much better than just the device the G5 comes with. Please fix this. So annoying.
 
This is Why I Hate Dexcom 
The app connects to the transmitters just fine. It just drops the connection without warning give minutes later. The super annoying CGM receiver still works, so it isn't the transmitters' fault. In fact, if you go into the Bluetooth settings on your iPhone, there is the transmitter, sitting disconnected. It can't connect from there, either. Maybe the updates to iOS are messing the app's connectivity up, but isn't that what updates are for? I'm a brittle diabetic. My BG swings unpredictably. I NEED this to work. I only use Dexcom because Medtronic is a joke and nobody else is selling. Apple, if you ARE making a CGM watch, I dearly want it.
 
Awesome app! 
This is a great app! As for the bypassing alarms, just turn the noise to vibrate only! EDIT: Not sure if this is my transmitter or the app, but it seems to lose connection somewhat frequently, resulting in me needing to reinstall the app. Still, great product.
 
It's a great product but with the new update it doesn't work!! 
I've been using my dexcom for over a year now and I love everything about it. However, the new update has made it so that every 5 minutes it tells me that I have to shut the app down and start again, even though it's still recording my blood sugar numbers on the screen. Oh, and as frustrating as all of this is, there is an incredibly loud beeping that is accompanied by the error message that I can't turn off. I would love to use the Dexcom app again but please, someone fix it!!
 
It's pretty amazing 
I would have given it 4 stars, but due to everyone giving it one star because of the alerts, I had to give it 5. This has been amazing. I do wish there was a "mute for x minutes" on the low alarm, but honestly, it's trying to help. The Apple Watch app is great, I just wish the complication was available on more faces. The main reason I didn't have a cgm before was not wanting to carry around another device and keep it charged etc. the ability to use the phone is amazing.
 
Crashes all the time 
Constantly crashes and tells me to restart the App. Very unusual. Worthless. You guys really need to work on this. Painfully disappointing
 
Getting there... 
The Dexcom app has its quirks. It NEEDS the graph view in which you can zoom out to full day/scroll through data. If the Dexcom Follow app can do this, our app should be able to do it! Also, when the app is closed out this shouldn't prompt a 'Signal Loss'. The app should be able to run in the background. Otherwise, great and helps track blood sugars and has gotten my A1C down significantly!
 
Seriously People.. 
I'm leaving this review only to try an counter app the negative marks this app seems to be receiving. Before using the Dexcom app, I was using the xDrip for android. Night and day difference between the 2. I made the switch to iPhone literally because of the ability to monitor my blood sugar easily. This app after over a year of use has worked just how I thought it would. Countless reviews keep trashing the "Loud alarms" yet that's the reason I use this app. If I'm asleep I want the loudest possible alert to ensure I'm awake and can treat a hypo. The repeat alarms for lows can be frustrating but that was the point, guess what when your glucose comes to normal it stops! I would like an see extended functionality especially with the trend of blood sugar levels in relation to on board insulin. But this app for real functions like it should, and after 26 years of diabetes this is the best I've felt dealing with the disease!
 
Pretty poorly run 
This app needs a lot of attention. It keeps asking to be closed and restarted. That's after the latest update. Would be really convenient if it was reliable.
 
xDrip+ on Android is better 
First. Dexcom uses the app to kill a transmitter after 3 months forcing you to buy them more often than needed. I used xDrip+ on am Android device for a while. Holy cow xDrip is so much better and they don't watch your data like Dexcom does plus they don't stop a sensor before it's battery is really dead. I really miss the predictive ability and larger data view with averages fro xDrip. Too bad there is not xDrip+ for iOS!!!!
 
Life Saving 
Without dexcom, I may have died multiple times. I cannot wait until the future innovations are released. THE APPLE WATCH APP IS GREAT
 
Really needs to be quite 
This is such a great product. But the app is not realistic. In school and your blood sugar drops then your Dexcom goes all nuclear sirens everyone looks at you and just was to loud for some areas. There really needs to be a vibrate only on everything. I know some people can't feel when they are going low which this app is very great. But if you can feel when you are going low you don't need sirens blaring in your ears. All I want is a vibrate only setting on everything, not just half the settings.
 
Why won't they fix these issues?? 
The app is convenient in the ability to see my blood sugar on my Apple Watch. However, I find it infuriating that you can't silence the alarms. There's times where I don't want it going off, no matter what my blood sugar is at. Tech support says if you want it to stop running on your phone for any amount of time, to fully close out the app by double clicking the home button. That would be great if that actually worked. I am constantly closing the app but to no avail, it's still going off. It's driving me crazy!!!!
 
Hate the new volume settings 
New update issue: I'm not getting signal loss alerts. This is dangerous and horrible! If I'm expecting to be told if my sugar is high or low. And don't get an alert, I assume it's normal. Not that my sugar is 400 and there's just no signal. FIX THIS!!!!!! Give us an option for the high alert volume. I understand the need for important alerts. But if I'm just sitting in bed playing on my phone, I don't need a heart-attack-inducing high volume alert a few inches from my face. PLEASEEEEEE give me an option to say how often it reminds me to enter meter bg value. I DONT NEED REMINDED EVERY 5 minutes! It's annoying and ridiculous. I'm about to turn off all notifications. Which defeats the purpose!!
 
Cant restart my phone 
Whenever i restart my phone, which i try to do at least once a week, and reopen the app, it says the app no longer works and i need to re download it this isn't life threatening but it is incredibly annoying...
 
Apple Watch 
Fix the update!!! It used to work great, my blood sugar would display directly on my Apple Watch and now since the update it doesn't work anymore!
 
Mute override cannot be turned off 
After months of frustration, my boy now refuses to bring receiver to school. Terrible software that treats us like idiots...
 
Freedom to silence 
Dexcom G5 is the best CGM I have ever used. The accuracy is superb and I rely on the readings heavily. It's disappointing to have to give a low star rating but after the recent update that makes it impossible to silence audible alerts I haven't been able to take my phone to meetings. I'm well aware when I am trending low and I preferred to correct silently without having an audible alert go off. As an Apple Watch user could we change the setting to just have haptic feedback? Not everything needs to beep!
 
Disappointing app for such an awesome device 
No real thought had gone into this app, Functionality is bare bones and there is zero ability to customize anything on the user interface. Let's hope Dexcom hire a UI expert someday to bring this app out of the dark ages.
 
Quirky update 
Calibration doesn't always work. In the previous version of the app, if I entered a new BG value within an hour or so of calibration time, I did not need to calibrate AGAIN 10-60 minutes later. Other times it doesn't "take" my calibration! Seems like a bug. Also sometimes the low and high alarms will be audible on silent and DND mode, but other times only the urgent low will signal the audible alarm when on silent and DND. Inconsistent and seems like another bug.
 
Great CGM, Terrible APP, treats all users like children/idiots 
My first review for an iOS app since I first bought the original iPhone many years ago. The Dexcom G5 CGM is awesome, this app is terrible and treats all diabetics like incompetent idiots. The Dexcom app is terrible. I am considering either deleting the app to carry the separate controller or just stop using the Dexcom CGM. I started using the Dexcom CGM because my iPhone could control the CGM (since I already have an Omnipod PDM and a smartphone in my pocket at all times). The un-mutable, non-customizable alarms might be great for children but I am an adult and I want to use a CGM as one of many tools to manage my diabetes. How I use it should be my choice. I have been living with diabetes for 26 years now. Every feature should be customizable by the user, or maybe an alternative app should be available for “advanced” users. If there was any viable alternative in the US for a smartphone controllable CGM, I would switch tomorrow.
 
Sub par interface choices 
For the love of everything get rid of the stupid red alert bubble for those of us adults that don't need anyone to "follow" us. And what everyone else is saying about the lack of choice and control for alarms. Also let alerts cleared on the  watch clear them on the phone. They're CONNECTED for goodness sake. Poach a UX person from T:slim (or just model them). They *get* diabetics. CGM works quite well. Totally let down by poor app.
 
Please listen to the customers 
I feel bad that I have to give this app such a low rating, because I genuinely appreciate having it. Using a CGM with info available on my phone and Apple Watch is a great set-up. But I want to add to the chorus of complaints about volume settings: this app is so frustrating because it acts like customers are deaf and can't be trusted to manage alerts how they want to. I totally understand that with a medical product you have to design for the least capable users, but AT LEAST put in customizable settings for those of us who can make the decision to alter notification styles. The lack of a true mute is terrible. As many have said, I simply cannot have a ridiculously loud warning siren going off in a professional setting. Dexcom, please listen to your customers and add this important feature!!!
 
Ultimate tool for diabetic althlete 
As a insulin dependent active individual I need to be able to be alerted on my watch or phone before I get dangerously low. This will sound a loud alert regardless of ringtone or vibration setting. There's not many options or a beautiful display, but it does its job well for a free app.
 
They have removed your control 
I have now stopped using the Dexcom due to inaccuracy and the annoyance of their forced notifications. Here is my email I just sent them: It woke me up with that obnoxious alarm last night at 4am saying my BS was 46. I tested and it was 121. I wake up at 7:30am this morning and it tells me it's 281. I test it and it's 161. This thing is so annoying and inaccurate, I can't even use it anymore. Further, as I've written in before, you've bypassed the Apple notification settings, which is offensive to me. I'm in church or in a customer siminar and these false readings make the alarm scream, even though I have Dexcom notifications off and have my phone on silent and do not disturb. It's rude of me, makes my company and I look disrespectful, and it causes a distraction for the speaker. You need to think this stuff through. I'm tired of Dexcom telling me how I have to manage my diabetes. It's my freaking life. If I want the notifications off, then I should be able to turn the notifications off. Is there an ability to get a refund? My previous review: I can't believe Apple let them bypass the notification settings. I had to turn off notifications in Settings to remain sane with the last versions, but with this new update, the alerts and notifications happen even with notifications turned off. Dexcom: Do I need notified 4 times of high glucose in 10 minutes when it reads 249, 251, 249, 251, 249, 251, 249, 251? No. I don't. I don't check my blood sugar every 12 hours on the dot. Why? Because I don't sleep for 12 hours a day. Therefore, I don't need a reminder to enter my glucose level EVERY 12 hours. Remind me if I've gone 24 without entering one. These are such simple fixes that would allow me to use this device to its full potential. But instead, it is so annoying that I have all notifications turned off and it's usefulness is heavily handicapped. Of course, now Apple let your app through without following the notification rules. I may just stop using it all together.
 
Can't silence low alarm 
Screams at you (for lows) without any ability to silence it. Extremely frustrating at times.
 
Watch app is great 
Love the accuracy of the Dexcom g5. The iPhone app is great but sure would be better with insulin on board. Because the app and sensor work so well together I got the apple watch. Now I have a new level of up to minute info on my wrist that has given me the confidence to attack my numbers and really lower my a1c. I am really pleased and look forward to what comes next.
 
Many changes needed 
I want silence back. Since FDA approved not having to check with this, remove the notification that covers the entire screen and make it smaller. Remove the noise notification when on silent.
 
No new update! 
This app is awful. There is nothing new with this update. They still have not fixed the main problem---giving users the control over the mute override functionality. Dexcom seems to be oblivious to the negative customer feedback they continue to receive.
 
Works great 
🔥
 
Turn off the arbitrary alarm please!! 
Or give the app the functionality to allow users to chose if they want the alarm to be on or off if the phone is in "do not disturb" mode in case some users are in love with this feature (certainly not the case for most users based on all the negative reviews..). I hate to be forced to shut my phone off every night as this is currently the only alternative to turn this alarm off.
 
Quitting in middle of night again 
The once resolved the nighttime failure problem is back. Combined with receiver issues, this is a real concern.
 
Vibrate is enough STOP THE ALARMS 
If I have already clicked OK on an alert (slide to unlock, then launched the app, then waited, then hit ok...a lot of work means I got the message!!), that means I have already addressed the low by eating carbohydrates. That will take time to absorb into my blood sugar, and it will take even more time for Dexcom to register the change. Please stop the app from screaming at me over and over again. VIBRATE IS ENOUGH!! So here's a risky hack I've started using: calibrate your Dex 10 mg/dl HIGHER than your finger stick reading. That way Dex won't misreport a 75 as a 65 at 3 am, screaming at you over and over again for an hour.
 
Watch functionality is dead. 
This update broke all Dexcom iWatch stuffs. Please revert or fix immediately. The Dexcom G5 isn't great if I can't see my BG on my watch. Thanks.
 
Dangerous 
This is a dangerous update. By removing the option to silence an alarm as you'd silence your phone, it makes this app unusable by people like me (I will lose my job if I have an alarm interrupt production). Newest OS update causes the alerts to be played even when the app is closed. Had to kill Bluetooth in order to stop it from going off at work. Forgot to turn it back on in the evening and woke up in the hospital on the next morning. Had my family not been expecting me, might not have woken up at all. DexCom forces a choice between employment and health. I'll find a better option, no more DexCom for me.
 
Needs To work with the Ring/Silence button built into the iPhone 
The app needs to comply with the built in iPhone volume functions. There is a reason for the Ring/Silent switch on the side of the iPhone. It is to silence your phone from alerts, especially during very important and/or sensitive meetings, presentations, church, weddings, funerals, and certain high school & college classes. I (and other diabetics) see this as a health risk because I now have to choose to 1) turn off this app or phone and not monitor my BGs during these events. 2) Risk getting in trouble at work/school where you are asked to leave if you can't silence you phone(e.g. College class, work meetings, movie theater, etc.). If you allowed the app to properly use and honor the vibrate/silence switch, we could properly use this app by allowing vibrations during meetings where we are required to keep our phones silenced. Then we could easily switch back to audio alerts when needed during normal times and at times such as when we are sleeping. Currently, we have to manually change the settings for the different events, which doesn't work properly and is very time consuming if you have to do this multiple times a day. Some areas that you can not silence are the following: 2 hour warning to enter BG, notice of sensor expiring, when the sensor expires, and Bluetooth communication errors. These will sound even if you put you phone on vibrate and there is no settings in the app to change these. Please add the option to allow the iPhone Ring/Silent switch to fully control ALL alerts including urgent lows, replacement notices, expired pod notices, and Bluetooth issues. I understand some diabetics may accidentally enable this switch and will still want to get alerts. So, can you at least add an option to enable or disable this mute override feature in the app settings menu? This will allow us the ability to choose to get silent notifications and be able to keep our phone on to monitor our BGs 24/7 without turning it off for these sensitive events. This will also allow the users who want to be notified by sound even in silence mode the ability to get sound notifications. Please make this a 5 star app by allowing us the ability to enable or disable the mute override feature. If that can't be done, can you at least make 2 versions of this app, one with mute override and one without?
 
Flawed assumptions about diabetics' priorities 
Dexcom®: Because losing your job and dignity is indisputably worth keeping your blood sugar in range. 🤦‍♂️
 
Apple Watch functionality gone 
This is the only reason I have an Apple Watch, now it's gone since the update.
 
Terrible app, wonderful product 
This is a terrible app which is unfortunate because it's a wonderfully useful product. My app glitches out every 30 minutes or so asking me to quit and restart due to a small error... but with every alarm I have a FULL volume shrill beeping that I cannot turn down or silence (even though my phone is on silent). Good thing I did this at home after work, bad thing for my nights sleep. After reading the other comments It's clear the company has lost track of what its clients need, or maybe they don't care any more. Bad business move either way. Either way don't get the app. Get the old receiver and carry two devices. I'm going to call to demand a G4 receiver that you can actually program to be quiet at work and which doesn't glitch out. Kind of alarming to have this app glitch so often...
 
Not a lot of user autonomy 
I wish there was a way for the Dexcom alarms to work while phone is in do not disturb mode, you know, the way the regular alarms still work. Seems like the life threatening alarm could still sound while still being able to silence my phone and sleep. When you acknowledge you are aware of your low blood sugar the alarms still will not stop. You hit okay but the alarms persist. It's very disempowering and embarrassing. When you take a break from your censor the app refuses to recognize this decision, again with persistent alarms telling you that you are disconnected. Yes, that's what I wanted but the app won't let you for at least for alarms. It's devices like this that make me wonder if diabetics are actually involved in the research and development processes of technology. Or are they only consulted in a focus group once the technology has largely been decided upon.
 
Bad, bad, bad! 
They do not read reviews, at the first opportunity I will change to an analogue
 
Always lost signal 
Whether I'm right next to my phone, using it, or whatever the case may be..it ALWAYS loses signal!!! I get zero signal overnight, as soon as I lay down in bed. Even sitting next to my phone at my desk it loses signal. Meanwhile my receiver is 100% perfect!!! What a disappointment.
 
Best of breed but needs improvement 
I really like the fact that this App and the Apple Watch App work (via Bluetooth) with the G5 Dexcom transmitter as it is so convenient to be able to look at my watch to see my BS levels. Like many other review comments, the alarms need work as having the iPhone on Do Not Disturb or on mute should not impact the alerts from overriding those settings and work as expected. Also, the Dexcom iOS developers need to get App updates out in a timely manner when Apple releases iOS updates. Apple releases the beta builds weeks beforehand so Dexcom should be releasing updates within a day or two of the public iOS release. Keep up the great work!
 
UPDATE NOW!! 
My app is CONSTANTLY crashing and telling me to exit and restart. And the alarm? Don't even get me started. Even with my phone on silent, it screams at me every time the app has an error and needs to be closed....which is literally almost every 5 minutes. This need "crashing" problems needs to be fixed ASAP.
 
Disappointed 
The constant alarms & no way to mark as treated. Not effect at controlling A1C but exaggerates treatment results in worse, not better control. Have become dubious of how 'real time' monitor even is.
 
Fantastic! 
Thanks for Apple Watch support, BUT PLEASE, make it possible to turn off the alert sound for urgent low level! I know that's low, because I feel it and my watch vibrates + I see the current level every time I look at my watch. When my iphone makes that loud alert noise everyone at the office starts looking at me and I feel like an idiot who forgot to turn off the alarm. PLEASE!!!
 
Unreliable 
I've had this for about 6 months. First transmitter was amazing, it always worked. Now, after receiving a new one it's constantly inaccurate and disconnects frequently. Got a replacement, and it worked great for 30 minutes then it stopped working and hasn't worked since. This is amazing technology when it works, but I've had lots of issues with this product.
 
Nonsensical, foolish, idiotic. 
It's to the point where I may delete the app. You STILL cannot set "vibrate only" for the urgent low alarm. This is still a much needed fix. I could see if the urgent low wasn't acknowledged after a certain time, but not alarm immediately as it crosses the threshold. Very disruptive at inappropriate times.
 
Silence the alarms for Peet's sake!!! 
This update still fails to address the colossal mistake and massive inconvenience your last update caused. There needs to be a way to silence all the alarms! I am an adult with a career and I can not have my phone making noises while I am at work! This app was supposed to make our lives easier and so far all its done is make it more annoying. I have already been written up at work for the alarm going off which makes me turn the app off at work, where I need it the most because I go low quite a bit from constantly doing physical things! Give me a way to silence the alarms or I'm going to be forced to stop using dexcom when I run out of the sensors and transmitter! This is a disservice to your customers to ignore our feedback and needs of this app! Give us a way to put the alarms on SILENT!!!!!!!
 
Nothing New 
There is nothing new with respect to the user interface or alerts. The UI still needs to be more interactive, more information. The alerts are still very narrow and not useful for many cases. In addition the Dexcom Follow app has never been updated. For parents with young kids, we need worthwhile alerts for the Dexcom and Dexcom Follow apps. 1. Knowing the CGM readings are delayed when there is a significant fall, by the time the low alert hits (at 100), actual BG can be lower than 50. The max low alert needs to be much higher to take into account these delays. 2. The fall rate alerts are of little significance by themselves, considering they usually start at high numbers. So if it's on, 9 times out of 10, it's ignored. Additionally, Dexcom Followers don't even get fall rate alerts. 3. We need tailored alerts - such as fall rate of X if under Y. We live with this everyday and know what conditions to anticipate. If we can set an alarm based on these expectations, it would take a lot of worry away. Otherwise, we are tied to our phones 24/7 waiting for updates. Just from my experience with my child, I know if there is a fall rate of greater than 3 mg/dL per min and his CGM hits around 150, then his actual BG is nearing a low and I need to treat soon. The features are already there, why can't these inputs be made available?
 
Unreasonable update 
The usability is still better than the spotty updates I got checking my BG a few times a day. Your update last year was a jump in a drastic direction, but I managed to come back and get used to. It may have been annoying, but I got used to it and ended up working with it. Now, it seems your widget is no longer accessible making your app less usable than before. I'm no expert in this sort of business, but it would be nice to give power to the user interface rather than continue limiting the usability of the app.
 
Come on! Give us a mute button! 
Here we are again with another update and the #1 requested fix is still not done. It must be the users choice to have alerts for all cases. It's on the user to decide what is important. At no time did my glucose meter jump at me because I hadn't made a test in the last 5 hours. This app should be a tool utilized by the user as they see fit. Give us control of all the alerts! 2nd review: 1 star I love that after countless reviews with a 1 star you guys don't even acknowledge the urgent low sound cannot be disabled on the last update. Give me a break. I understand this might be forced by the FDA, but I thought the FDA approved system was the separate receiver; why can't this app conform to the users requests?!! 1st review: 1 star Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
Make Urgent Low Alert Silenceable 
It works great, but it is super inconvenient to be unable to silence the urgent low alarm. For those that don't need it, they should be able to turn it off so it doesn't disrupt the users' lives. Those that need it or want it will have the power to keep the alarm on. This makes intuitive sense. Please listen to the responses about the urgent low alarm. User feedback will improve.
 
Vibration option needs fixing 
just had an enhancement request. It would be great if the Dexcom App would allow you to specify Long-acting versus Short-acting insulin doses. So for example when I wake up I have to put in "7units" (for Lantau) and then immediately followed by "2units" for breakfast. Would be nice to differentiate the two. Thanks!
 
I need to be able to MUTE the alarm 
Like all the other reviewers have stated.....I need the ability to mute the low alarms. My wife hates this app since it keeps beeping at night. It's not appropriate for important work meetings. Even after I have addressed low blood sugar it continues to beep when my blood sugar is rising. I need the ability to silence this thing from my iPhone. Otherwise, easy 4 star review if not higher. It's a basic app that does exactly what it should be doing.
 
Love it 
I know that the most common complaint is the inability to silence alerts. This is ok with me as much because I leave my phone on silent during the day and forget to turn the volume on at night, and now I don't have to worry about it. HOWEVER, I would still like to be able to turn them off if I'm in a movie or meeting and I would like to be able to silence the alarm with my Apple watch. Instead, I get the alert with my watch, and if my phone is in the other room, it keeps going off until I get up and go silence it. Extremely inconvenient. I would also like the ability to set times for the alerts. I'd like my nighttime low alert to be 100 and my daytime low alert to be 70 since I aim for different numbers at different times of the day depending on how close I am able to pay attention.
 
Change the alerts 
I should be able to turn off all alerts. This app is supposed to be for MY convenience.
 
Screw this app 
This app is way to complicated and it doesn't ever work. It took 5 hours before it decided to work
 
Like having two options 
I appreciate having the phone as a backup to my receiver. The phone would be more useful if the app contained two more features that should be easy to add. 1) When displaying a notification "Glucose low" or "Glucose High," could you please append the reading to this notification. Why? Because Some people use a garmin smart watch, and it would be helpful to know the number. 2) This would be more work, but very valuable. Add a feature where we can have notifications sent on a repeating schedule. We can choose the interval (off, 5 min, 10 min, 1 hour, etc). The notification displays current glucose. Why? If I'm riding my bike (or anyone who is being active), notifications are displayed on Garmin smart watch. This has two benefits: 1- it allows us to leave the phone in pocket while engaging in sport 2- having the interval can help us be more cognizant of our situation. This is more useful that low /high alerts because by the time you're low or high, it can be too late to take action. Thanks!
 
Not a lot of user autonomy 
I wish there was a way for the Dexcom alarms to work while phone is in do not disturb mode, you know, the way the regular alarms still work. Seems like the life threatening alarm could still sound while still being able to silence my phone and sleep. It's devices like this that make me wonder if diabetics are actually involved in the research and development processes of technology. Or are they only consulted in a focus group once the technology has largely been decided upon.
 
Volume control missing 
Overall love dexcom! But a few improvements could go a long way. Loud alerts but keeps you from ignoring your lows ;). I'd love there to be an option for a smaller graph, maybe up to 200 instead of 400! I try to stay around 90 but rarely go above 140/160 so my graph has heaps of unused space that make it more difficult to see fluctuations. I also would like to be able to put in carbs as well as protein to monitor longer reaction times to protein digestion.
 
Needs Improvement 
Dexcom is awesome but once you get past the excitement of finally seeing your glucose trending, the app leaves a lot to be desired. It's only interactive if you tilt your phone to landscape. They should put your glucose number on the app icon so you can see your sugar without having to open the app. Clarity reports are great, so some summary data should be integrated into the basic Dexcom app.
 
Good, except... 
There are glitches here and there that need to be addressed such as bringing up the volume overlay when notifying the user of a glucose alert.
 
Great tool, but app could use improvement 
I have not had any problems with the app. It has worked well for me, but it does need updating. It is still not formatted for a plus device. It also is not optimized for the newest iOS. You have to leave the app running. It should be updated so that it will run in the background to save battery. I also hate that they play sounds while my phone is in silent. I appreciate why that is here, but I smart enough to know when my phone is or is not is silent, and when I am in a business meeting, and want to ignore the high notification for a minute, I do not want it to play a sound on me. It would be great if it was a option to ignore silent or not.
 
Let me turn off alarms 
This is completely unusable. It is NOT possible to silence the Urgent Low Alarms or the initial calibration alarms. DO NOT INSTALL.
 
Could be Better 
The app is pretty good on my phone, but it needs to be improved on my watch. It would be so much better if you didn't need to have your phone with you to have it read on your watch. It should be able to communicate with the transmitter. As a runner, it would make my life much easier if I didn't need to always run with my phone just so I can see my blood sugar.
 
For the love of God, silence the alarms. 
I love this app so much, but the update doesn't allow for silent alarms when my phone is on silent. It's all or nothing. Either I silence all the alarms all the time, or they go off at work, in class, at exams, in the car, in ALL the places where I'm supposed to be quiet.... Please put the silent option back on. I love everything about this otherwise. It works great.
 
Needs To work with the Ring/Silence button built into the iPhone 
The app needs to comply with the built in iPhone volume functions. There is a reason for the Ring/Silent switch on the side of the iPhone. It is to silence your phone from alerts, especially during very important and/or sensitive meetings, presentations, church, weddings, funerals, and certain high school & college classes. I (and other diabetics) see this as a health risk because I now have to choose to 1) turn off this app or phone and not monitor my BGs during these events. 2) Risk getting in trouble at work/school where you are asked to leave if you can't silence you phone(e.g. College class, work meetings, movie theater, etc.). Please add the option to allow the iPhone Ring/Silent switch to fully control ALL alerts including urgent lows, replacement notices, and expired pod notices. I understand some diabetics may accidentally enable this switch and will still want to get alerts. So, can you at least add an option to enable or disable this mute override feature in the app settings menu? This will allow us the ability to choose to get silent notifications and be able to keep our phone on to monitor our BGs 24/7 without turning it off for these sensitive events.
 
Alerts 
Please please please!! Allow it so that alerts can be silenced by the silent switch on the iPhone. I am a student and it goes off during class constantly and it is blaring! Please fix this
 
Wonderful Apple Watch Update. Horrible audible notifications 
The Dexcom G5 is really quite a mix of good and bad. The newly updated Apple Watch support is wonderful. Game changing. Exactly what I wanted from Day 1: I can easily and discreetly glance at my watch and see my glucose levels. Dream come true. The bad: The awful notification sounds that CANNOT be silenced. Why in the world did someone think it was a good idea to force a user's iPhone to make sound, ignoring the owners wishes? I work in a professional environment. I can't have my phone making extremely loud sounds during meetings, presentations, etc. I need to have the option to turn them off. Especially since I can view my status via my Watch. Why force me to take out my phone, open the app, and acknowledge an alarm?
 
Nonsensical, foolish, idiotic, stupid update 
You STILL cannot silence the urgent low alarm. This is still a much needed fix.
 
Easy TURN OFF ALARM or Turn down 
My goodness people turning off or turning down your alerts is so easy I'm afraid for you all. In the top left of your screen are 3 horizontal bars. 1. Touch these bars 2. Menu opens 3. Touch Alerts 4. See all 6 kids of alerts Urgent low, Low, High, Rise Rate, Fall Rate and Signal loss 5. Open each of these except for Urgent and Turn off. You can not Turn off urgent low For obvious reasons. A juice box or other fast Acting carb will silence This in no time. 6. All five other alerts can Be turned off or set to Vibrate for no sound 7. Also if you still want Alerts just not at full Blast. Choose the Sound you like and you Will have a few seconds Turn down volume before Ringer volume switches In to control by phone Volume It's that simple more choice to set than you could ever want. NO you can't just set silent by phone switch. Think about how often that get hit unintentionally or if you use your phone for work and it rings constantly you might want that off so not to disturb but still want Dexcom alerts. They are separate for very good reason Dexcom must have thought of all this.
 
Needs a dozen bug fixes 
There are simple bug fixes they haven't addressed since day one it came on the market. The most simplest is when you turn the phone volume down to super low, the alerts still blare at 100% volume! Such a pleasure waking up to that every 3 hours in the night when your high! I've told their Dexcom support people and they have supposedly made a report and told their higher ups but the simple issues still exist. That was over a year ago. And what's more? They come up with an update recently, that makes stupid changes to sound effects, like the fact that it can still make noise when on silent. WOOPTY FREAKING DO! Make it so that it can be more fine tuned, instead of a one size fits all respect! I don't feel like a medical device this monumental should have such huge issues within its software, it's just appalling in my eyes. I was told that they can't make changes to the appt, without making changes to the screen thingy that comes with your cgm that you don't have to use if you use the iPhone appt. The tech person said they would have to change that little machine too. And that everyone would have to receive that new machine. Well that's obviously not true because they came out with updates on the sound recently. The simple bug fixes should have been noticed and changed long ago..... How about the low alert number being only as high as 100. I want it to be higher like 130 instead of just 100 as the highest alert low option. Because at 80 I can't drive a vehicle as it's to dangerous and I'm not able to control my body as well. When I'm 100 I'm usually on the way to going much lower, it's never 100 and "going side ways" arrow. How about the urgent low alert number being only 55, that's ridiculously low for some and I start having breathing and sight issues at that point! Make it higher! How about the fact that the re-alert rate for highs or lows has a 5 and 10 minute marker, but they DON'T WORK! When trying to choose the 5 minute mark, it swooshes to 0 minutes (and why even have the freaking 0 in the first place? Stupid.) When trying to choose the 10 minute mark because the 5 doesn't work, it swooshes to the 15 minute mark. Hence the least amount of time you can make it alert you is 15 minuets between alert notifications. If your going low you know that 5 minuets can make drastic changes if you've over dosed. And say your dropping but the drop alert isn't triggered. How about the fact that it grays out sometimes and I have to restart my phone to get the glitch to not be there any more. When the appts grays out it's like when the phones about to go to sleep and the screen turns grey first, but it only happens in the appt and nothing in the appt is press able. Even when you exit and pull the appt up again. It happens when multiply alerts come at once and the iphone can't handle them along with the other things it's thinking about. I have the iPhone 6s. This shouldn't happen. I was advised by the tech support to uninstall and reinstall the appt because maybe the new firmware didn't go with the new update, but this doesn't have to be done with other less important appts. Unacceptable. When my little pod thing was getting to the end of its battery life and I was on vacation, I knew I had two weeks left on it before it died because it tells you at like 6 weeks then 3 weeks then 2 weeks. I would be home in a couple days and would change it when it died. But then it was time to change a sender as its 7 days was up and I changed it and when I pressed restart senser, it said replace pod thingy. But I had at least 2 weeks left on it and it was making me replace it! I tried many things to out smart it like typing in the same serial number for that same pod thing and it would work for a minuet then glitch out and say replace it. So I had to go for days without it which was like living during the 17th century for 5 days. Sometimes the sound won't shut off when there is an alert and I press the phone button that are on the side of the iPhone. The volume on the phone can be set to medium or soft and alerts still come in extremely loud as if the phone volume is turned all the way up. This is incredibly annoyed at night when your phone is right on your pillow. And no it's not on silent or whatever the new pointless update involved. You can set alerts to alert you every hour or two hours or three hours or whatever. But it doesn't register with what you think you're setting it to. I have mine set to two hours right now but it really alerts me every half an hour if I change it to three hours it will probably alert me once an hour. So the time markers are not equivalent to what they actually say.
 
Deaf from extra loud tones 
The in ability to adjust the volume is ridiculous. During the day when there is a ton of ambient sound makes sense to have the alert at full volume. At night is an entirely different story. The alert is deafening and can only be turned off. So everyone has to suffer and our choices limited since someone somewhere couldn't figure out how to use the app and had a low or something that was missed. I only chose dexcom because it was the only app in the smartphone platform. It may be the time to shop for another alternative.
 
We've been listening to your feedback????? 
Hardly! No way to mute the annoying alarms. Enough said.
 
Alarm complaints are way overblown 
I want to clear the air here...this app changed my life and the complaints about the alarms are uninformed or simply petty. There are three scenarios in which the app will alert you regardless of your settings: 1. Urgent low glucose - The level is set at 55 and is unchangeable. The alarm is fairly loud. But who is dipping to 55 everyday? So many people are acting as if this is some hourly alarm when an urgent low is not an everyday occurrence for the majority of diabetics. The alarm will repeat every 30 minutes but your blood sugar will have almost always risen past 55 by then. And the alarm is not like a ringtone - it is a simple notification (like a text message). I have also been woken up by this alarm before. I don't know about you guys, but I find that pretty valuable... 2. Notification that the sensor warmup is complete and awaiting calibration - After insertion, the Dexcom G5 will warm up for two hours and then require you to input the results of two back-to-back blood sugar tests. There is an audible alarm after the warmup period. Guys, we are talking about one audible notification A WEEK. And frankly, you will do most of your insertions in the evening or a day off, so the alarm is not likely to be all that intrusive. 3. High glucose warning - This is a notification that your BSL has reached a level that you have chosen yourself. THIS CAN BE SET TO VIBRATE! I find this notification to be fantastic. I have it on vibrate and would choose to have it even if it was optional. I have had this device for a year and half now and it has changed my life. The ability to see your blood sugar level and trends in real time is simply mind blowing and perhaps something only long time diabetics can truly appreciate. As soon as the app was able to have a numerical complication on the Apple Watch, I purchased a Series 1 model. $269 and I can see my blood sugar with the lift of my wrist. This was another game changer - I use the app on my phone much less often now. Worthwhile investment even for those previously not interested in the watch. As with any product, it isn't immune to flaws. My main gripe is signal loss. It seems to drop signal once every couple days which can be annoying once you check the app only to see it hasn't been providing results for the past hour. There is a setting to be alerted when this happens (which I have turned on) but it doesn't seem to work for me. Perhaps a bug to be fixed in a future update. I would also like to provide tips for current users. 1. Yes, the sensor will stop after 7 days, but you can override this by simply initiating a new warmup period. 2. You don't have to go into the app to see your BSL! Add it as a widget on your phone and move it to the top of the list. This will give you a quick glance with a quick swipe to the left from the lock screen. 3. The majority of the alarms are customizable. I'm only adding this as a tip because people don't seem to understand that. TLDR; This app was a life changer for me and the complaints in recent reviews are petty and vastly outweighed by the abilities of the technology itself.
 
An idea for the next update 
I can handle the noise, I also can sleep through anything. That said. The options to silent everything wouldn't be bad. For day awake hours, and setting a night mode/alarm clock setting, to do that. Have your reading open and going, and an alarm clock to use. Or for people like myself. Alarm loud for issues. In life my only issues are while sleeping. But each person is different. And a setting to accommodate all is tough. But keeping the app open being able to glance at my phone to see where my sugar is at would be nice. I've got the watch and yes do sleep and glance at it. But still isn't something as convenient as looking at a phone screen.
 
Alert for calibration is very obnoxious 
I feel like this app has been written with only the 80 year old in mind. I know how to use my devices and a single alert is enough to tell me I need to calibrate. If I forgot, and don't have access to my meter, I shouldn't have the never end alerts saying I need to calibrate every 5 min. I get it. I need to calibrate when I can. A major problem with this is it really wears down my battery life if I forgot to calibrate before leaving for work. This doesn't happen all of the time. It when it does, my phone is dead by afternoon because the screen turns on every 5 min due to this alert. My suggestion here is to send alerts until the user acknowledges. This is how it was just a while ago. Once acknowledged, don't bug the user again. If you must bug the user, alert something like 6 hours later. At current state I really don't like this app. Watch update is awesome. But this one issue is a killer to the app.
 
Good app 
This app works as expected. I have no issues with the audible alert for urgent low. You can customize which sound to use and also the volume level for the alert. I use the single Beep and have the volume turned down very low. I do wish you had more flexibility to set your alarms. It would be nice to set the high alarm lower than 120, but that is not possible on the app or on the Dexcom receiver. Would also be nice to be able to set the rise/fall alarms for a single diagonal arrow. The minimum you can set those is a straight up/down arrow, I would prefer to be able to set the rise/fall alarm anytime I am not with a straight,horizontal, arrow. All in all a decent app.
 
Alerts and alarms are the downfall 
This app is great otherwise but the alerts and alarms will drive you/your spouse crazy. No way to silent them and the intervals are way more frequent than the "30" minutes I have them set to. It's not like my blood tester will start alarming until it gets a reading in range. Not sure why this can't be user specified on the G5.
 
Went from Great to Deleted with a single update 
Loved the Dexcom G5 system until the latest update. App overrides the iPhone mute/Do Not Disturb setting, causing issues with meetings/movies/etc. Talking with insurance about switching back to Medtronic
 
It doesn't even load now 
Since updating to "latest" version, it does not even load on my watch.
 
Bring the mute function back! 
It was great several months ago when the alarms could be silenced. Now, several updates later they refuse to bring back that feature. We all live busy lives and it's ridiculous that when we put our phones on silent that the alarms still go off. Completely ridiculous!
 
Sound/Signal 
This app has gone from useful and convenient to unreliable and annoying. As with all of the one star reviews, I am extremely unhappy about the changes with the sound settings. Aside from that, for the past two weeks now I have consistently been seeing the black signal loss bubble on the screen, while the Dexcom device is functioning perfectly. It's as though I downloaded a free trial version of this app and my time limit has expired. The ONLY workaround I have discovered for both issues is to just close the app altogether and revert to carrying the device again. I will say the reliability of the device vastly exceeds that of this app.
 
discrimination 
They believe that we are not normal people. I can not use it in public places.
 
Terrible App 
The Dexcom app is terrible. I continually get signal loss or question marks on my iPhone. It doesn't matter if the sensor is 1 day old or 10 it also doesn't matter that the sensor is less than a foot away from the phone. Dexcom support has me delete and reinstall the app. The dedicated receiver works fine all along. No other issues with BT on the iPhone. PLEASE fix this terrible app. If the sensor won't work with the phone how can it possibly work with the new Tandem X2 pump when it's approved?
 
Please upgrade Dexcom Follow simultaneously 
It is a great feature to have the new Apple Watch complication. Unfortunately, it doesn't help a large number of parents who must use Dexcom Follow instead. My son has the Dexcom G5 app. My wife and I have Follow. Perhaps in the future you can develop one app for both primary and secondary users.
 
Good, but still needs work 
Almost there! The Watch face complication is awesome. Need to fix when dismissing an alert on Watch, should also dismiss it on the iPhone. Other issue is the forced audible alert which is very, very loud, need a way to turn it off!!!
 
Great app but needs some fixing 
PLEASE fix the volume control for the alerts! It's driving me crazy! I rely on this app to help take care of my daughter, but am so annoyed with the loud constant beeping that I am tempted to delete it.
 
Hate the update 
Love the app but hate the latest update. Really need to have the flexibility and control to completely silence the phone. Please give us the option or bring back the old version. 1/22/17 Still waiting. Hate that I can't mute it. Am using it only for urgent lows...have all other alerts turned off. Kind of pointless!
 
Terrible update that doesn't allow alarm silencing 
I wish I read the reviews before updating ... now we can no longer silence the dexcom alarms! So even if your phone is on mute AND "do not disturb" your high and low alarms will come through. This is an almost insurmountable problem for working professionals and people who attend events where silence is required (e.g., movies, concerts, etc). Shame on Dexcom for not thinking of quality of life issues with this update!
 
Silent Alarm!!!! 
You didn’t fix the key complaint—mute override. This app is terrible for anybody with a professional career. I want the ability to control my diabetes with this app, not notify my colleagues that I am a distraction and have a disease.. This app is a disruptor to everyday life!!
 
Garbage 
Not only is the Dexcom App garbage but so is the system itself. I test my blood sugars MORE often since I've been using this because I have no faith in the system. Glucose readings are ridiculous. Once my supplies are gone, thats it. I'm done. Don't waste your time or money.
 
problems with the new app update 
App shuts off on occasion and not by accident. Glucose calibrations not being saved on rare occasions.
 
Lost signal 
As a teen, I FaceTime a LOT; but every time I FaceTime someone, my app loses signal and my parents can no longer see my BG.... it's very frustrating and I'd like for it to be fixed. Other than that, great app.
 
Huge step backwards 
This latest release is so bug filled it is beyond useless. It reports several times a day that it has encountered an error and to restart the program and when it's not doing that, it reports loss or signal. If this continues for another few days I plan on contacting the company to refund my money until they get their software working
 
Make profiles 
This app need profiles similar to the one in the original device but can be edited by the user. Also. The profiles should include not only the tone but when. Like a profile with vibration repeating every hour for high above 200. And another profile can be a tone I choose for high above 180 repeating every 30 minutes. The first one would be for something like a class so I do not want everyone to turn around and look at me. The second one would be for bedtime for example. Like for each profile you can set as a user all the alarming settings. Now I have to change all the tones to vibrate before entering the class and go back and search for the tones when I get back home. This is so annoying. I really preferred being able to make it silent or do not disturb mode but this should solve it
 
Works, but can be so annoying. 
I just completed my first installation-use-replacement cycle and I thought I would share my experiences. It works, that's the short version. The Pros: Easy access to your BG number without a separate test, seems accurate as compared to the normal unit, low/high BG alerts (but see below), having the transmitter stuck to me is very annoying but not awful, makes it easy to spot an increase/decrease trend so corrective actions happen sooner and lastly it shows my BG/alerts to my wife through her phone giving her great relief I am not having an undetected low/high BG episode. The Cons: Occasionally loses signal for no apparent reason, having it stuck to me is annoying, COST!. The biggest con is the smart device software, OMG can it be a pain in the butt! I read many reviews on iTunes and I concur, it needs work. I get that it needs to do what it needs to do, but the reminders and alerts are ridiculous at times. And right now there is no way to change or mitigate the issues, short of just turning it off. In general I am very good at self-detecting low BG, but I understand this ability can degrade with age. I am hoping that this device will help prolong my ability since it INSISTS on corrective action at 55 and below with alerts. This may keep me more sensitive to low BG in the long run?! But, this is actually a gripe too. Twice in this first week I was low or nearly so, but also very close to a mealtime. I was "forced" to raise my sugar just to get the stupid alerts to stop when I otherwise would/could have easily and safely just waited to eat. I know this is an odd scenario and will not happen often, but it's something one has to be aware of. And yes I know I could just have turned it off. I am definitely a fan overall and I am glad I decided to try it. Please note I haven't set up the dedicated receiver yet, I have only used the iPhone as a receiver. The inability to silence this app is just stupid. Again, I get it needs to do its mission but here's and idea. Allow silence with and affirmative code-entry, and for a set duration? This way you (Dexcom) is off the hook if someone has an issue, but yet allows some control so the app doesn't keep beeping when you don't want or need it to.
 
LET ME SILENCE THE TWO HOUR WARMUP!!!! 
I used to change my sensor at night, start the two hour warmup, and then go to sleep. I'd then enter my two calibration settings in the morning. NOT ANYMORE!!! The #%<*€}| app will incessantly beep at you, ignoring vibrate and silence and everything ALL NIGHT! It is NOT POSSIBLE to sleep until you enter your initial readings!!! Makes me want to throw my @&$#%* phone against the wall!!! What is wrong with you Dexcom?!?!?!!?! Are you completely out of your &$@#%{* mind?!?!
 
I Hate you, Dexcom. 
On your most recent update, you stated that you had listened to your customers. You may have listened but you did not follow through. Your rating on here is horrendous. Yet you do not bother to listen to the people who are buying your products. With that being said, the ongoing loud penetrating sound that overrides my iPhone is driving me mad! Everywhere we go, we draw attention and everything I do is interrupted by your product. Is there a plus side to having dexcom? Of course there is, but I was also doing fine by just checking my own sugar. The app is disruptive in church, meetings and events. The constant madness by your stupidity is leading to other alternatives. Add a feature that allows volume control!!! Dexcom...you were not in my live before and soon you will be out. I hate you
 
Poor Apple Watch capability 
I have been using the Dexcom G5 for a while now and I absolutely love it. It has been life changing to know what my blood sugar readings are at all times. However, I have a few major problems that cause me to give this app 1 star. I'm hoping these will be fixed in the future. 1. You are not able to silence urgent low blood sugar alarms without opening the app in your phone and acknowledging it. Like many other reviews have stated, this has been terrible for me. I am a nurse and I keep my iPhone in my pocket while I am at work. If my blood sugar starts dropping while I am in a patient room, it will quickly start alarming VERY loudly until I can get to my phone to turn off the alert. As you can imagine, this is quite a problem for me. Something I could lose my job over. My only alternative is to turn my phone off and not get my blood sugar readings. 2. I recently got an Apple Watch. I love that I can lift my arm and look at the Watch face to see my blood sugar readings without having to get out my phone. I THOUGHT the Apple Watch was going to fix the alert issue I mentioned above because when you are wearing the Watch you can acknowledge alerts right from your wrist and they are dismissed on your iPhone. HOWEVER, when I acknowledge a low blood sugar alert on my watch, I still have to pull out my phone, open the app, and acknowledge the alert there to prevent the very loud alarms. This kind of defeats the purpose of this very expensive Watch right now. If these issues get fixed, I'd definitely give this app a 4 or 5 star review. Until then, the app is causing more harm than good.
 
Give me back control 
How did Apple approve an app that overrides the mute button? To have audible alerts or not is MY choice, not Dexcom's!!!
 
Awesome app! 
This is a great app! As for the bypassing alarms, just turn the noise to vibrate only!
 
Signal lost 
It's supposed to replace you having to carry around your transmitter but it keeps losing its signal!! Never really works and unreliable.
 
not optimized 
it's 2017, how is this app not optimized for the iPhone 6 screen?
 
Notifications 
There needs to be an option for a vibrate/silent notification. I can't have this going off in meetings. Lows happen from time to time, but I can't keep having buzzing while I am in the office. I eventually just had to turn it off. Not the best choice, but my only option.
 
Please add option to MUTE urgent alert. 
Very annoying that this feature hasn't been added yet. Please listen to your customers and add this soon.
 
ADD MUTE 
Look, Dexcom. With the amount of money I've invested in sensors, transmitters, and the whole nine yards... I expect the application for my phone to work the way I want it to, or at least the way IT USED TO WORK. No longer can I use your application, your transmitters, or your sensors. My investments are worthless, and your application is now worthless. I haven't used my CGM since December. That's ridiculous. I have trouble monitoring my sugars and keeping track of the trends. Because you guys are not listening to what your customers want. Fix the app, please. I have no use for my gear without it. It was a life saver. Now it's a money waster. Get your brains working. YOU HAD ONE JOB!!!!
 
SILENT ALARMS! 
Please let me silence alarms again!!!! People who use this app have jobs and are professionals! It's super embarrassing to have this app go off during meetings or even when I'm at my desk. It gets so annoying I have to close out of the app all together. Most people have their phones on them at all time and can tell physically when their blood sugar is high or low, so making the alarms so annoying is really inconvenient.
 
Silenceable alarms 
This is absurd. How do I go to a movie, sit in a meeting, or attend church? I should be able to lower the volume at least slightly. What happens is that I end up closing the app- which defeats the purpose of having it! The phone repeatedly blares and it's making it UNUSABLE
 
People should really ...... 
For all of you complaining about alarms go into settings and adjust how you see fit i.e. Turn on vibrate or off. This is not Dexcom's fault once again a bunch of whiny cry babies not knowing how to go into settings and make an adjustment. Plus if you have Bluetooth earpiece or headphones and you have sound it will play privately.
 
Seems to be moving in right direction 
I just received my G5 system last week and, after seeing so many negative reviews, I was a little apprehensive about my plan to use my phone as the only receiver; but I have been pleasantly surprised. The alarms ARE all silenceable and customizable and the Watch complication surpassed my expectations of its helpfulness. That said, all this wireless activity and notifications are a little battery-intensive, and I've found it more than worth it to purchase an external battery case (Mophie and Apple both make solid options) to ensure I have peace of mind and access to my readings on my phone. Overall, a well functioning app and I hope that future updates continue to move in the right direction
 
When I can mute the alarm I'll give it 5 
I LOVE Dexcom but it's a serious issue for my bf and I at night...if I acknowledge the alarm and decide to mute it I'm obviously already taking care of the issue..this is so unacceptable
 
Not usable for adult 
Was a great backup. Liked the CGM. Stopped using recently and life has improved for it. Dexcom won't let you silence alarms anymore. You can't use vibrate only on certain alarms either. The problem here is obvious: if you have on, you're always at risk of having a loud, non-silenceable alarm go off at any time. Can't turn off in business meetings. Can't turn off in movies. Alarm repeats every 5 mins. If you sleep on your stomach CGMs, including dexcom often give false low readings. Again, no way to silence. No way to have vibrate only. Only options are to have it wake you up every 5 minutes or to remove the system. I've gone to a different brand. Much happier. Don't get woken up at night with false readings after I silence it once. Phone doesn't risk going off every 5 minutes with no way to go silent mode anymore. Was good product, but not usable as part of an adult lifestyle.
 
Love this app 
I recently got the G5 sensor and was worried about this app due to the negative reviews. However, the FAQ section in the help menu explains how to set "vibrate only" alarms for all alerts (except an urgent low -- less than 55). I do not mind an audible alarm when my BG drops below 55! I also love being able to view my BG reading via my watch. This keeps me from having to carry around a separate device to see my trends.
 
Why does the volume go off of the games 
We went to my doctors office to get my check up on my type 1. And concluded that the alarms have a big part to the problem. I found out the alarms go off of game volume or normal volume not ringers. Please put it on ringers.
 
Almost Unusuable 
I've had this app for quite a while now and have been through all of its "updates". Needless to say, I haven't noticed much of a change. The biggest drawback for me is the sound issue -- WHY CAN'T I COMPLETELY SILENCE THIS APP? Even when I turn off the app's notifications, I still get a blaring alarm when I have high levels. As a student, this is disruptive/embarrassing when I'm in class or in a meeting. Having Dexcom is extremely helpful to me, but what good is it if the app is causing an extreme inconvenience? People rely on this app for their own health and safety, you'd think the bugs would have been worked out by now...
 
Need to be able to silence alarms !! 
When I start a new sensor the readings are inaccurate for the first ~24 hours. That in itself is fine, understandable. What's not fine is the false urgent low alarms waking me up at night, without the ability to turn them off. Please add this ability back. --------------- (Old review:) Great app, does its job wonderfully. This app plus the G5 have made a huge impact on my daily diabetes management. Love the new widget! Only wish is being able to pinch zoom in/out and pan the graph in the app when the phone is set to landscape mode, and be able to write in my own words what food I had when adding a Carbs event (in addition to the carbs value). UPDATE: Love the Apple Watch support!! How about being able to enter BG values through the watch? UPDATE: Hooray for BG and trend arrow in notifications!! This app is getting better and better. Keep up the good work!
 
If I could give negative stars 
This is the WORST update I've ever seen from any company. They have taken so much control away from the user. OBNOXIOUS, LOUD alerts that are no longer managed by the user are a nice step back in time. I have an apple watch and it was gret being able to look at my watch while at work. As an ICU RN I don't need my watch screaming that my BG is high if I've already acknowledged it and made a correction bolus. I have it set to remind me every 90 minutes but your "update" ignores my preferences. Shut your pie-hole Dexcom! Also, thanks for telling me every 5 minutes that my sensor will stop working in 4 hours, very useful for people with short term memory loss. Worthless now, I've stopped using it until they correct all of their problems. Considering going back to Medtronic now. Nice job!
 
Let me turn off alarms 
Good lord.
 
PLEASE change it back so alarms can be silenced! at least on do not disturb.
 
Don't install update!! CANNOT SILENCE ALARM :( 
Dexcom, WHYYYY?! I'm so mad about this update I can't explain. I updated my app for the Apple Watch update not knowing there were audio changes. My alarm went off in a meeting and it was so unprofessional! All of my coworkers thought I was dying and I had to explain that 206 BS after breakfast is normal. Now I have to move my alert setting much higher which totally defeats the purpose of this app and the reason I got an Apple Watch. PLEASE REVERT or at least give us an option for audio setting overrides!!!!
 
MUTE BUTTON PLEASE 
Look I love the app an all but when that update came where I can't mute it I'm not happy with it I might as well keep the app off all the or even delete it(tip: change it back and you guys will get better ratings)
 
Improve please. I use the app instead of monitor. 
Loses connection from transmitter a lot. I keep app open that's the only way it doesn't lose connection.
 
Fantastic device, poor software/app 
Data analysis is minimal using this and Dexcom clarity. Connection to the G5 transmitter is lost too frequently. The time to keep up with Apple OS is longer than many other apps.
 
Needs adjustable axis 
I agree with the other users that the inability to silence the urgent glucose alarm makes it impossible to keep my iPhone on while in churches, movie theaters, and other silent places. Yes, I know that it is a medical device, but other people don't know that when they start yelling at you for your phone going off in public. I usually end up turning off my phone and losing all Dexcom monitoring while in these places. My bigger complaint is the inability to change the y-axis on the CGM graph. The only current choices are 400 mg/dL and 300 mg/dL, which leaves a well-controlled diabetic with a graph that simply looks like a little line across the bottom. The graph is useless for those of us who are working for tight control and need to see nuances in blood glucose within the acceptable range. As a scientist, it infuriates me that I cannot make the graph fit my data.
 
Needs a "silence" mode 
I've just switched to the Dexcom CGM after several years using the built-in Minimed sensors with my pump. (My doc at Joslin kept pushing Dexcom for better accuracy.) App seems perfectly acceptable, though (as many have noted) having a simple way to silence the dang thing is a win. Great that they now how an option to override the phone's "mute" mode, but this itself should be optional. Either have a setting to enable or disable their mute override, or else have a separate "silent" mode that can be enabled for limited periods. (The Minimed has an "alert silence" mode that you can enable, and you specify the time until alert sounds are automatically restored. This works well, say, for going to the theater: at the start of the show when they remind you about cell phones, turn on silent mode for two hours, and later alerts come back without any further action.) For now I've set everything to vibrate only, which keeps the app mostly non-disruptive, except for the visual annoyance of the bright screen when I clear the alert in a dark theater. A timed "no alerts" mode would fix this.
 
I agree 
I agree with many users asking for more control over sound alerts. I am an educator and similar to students who are posting here, it is tough to institute rules if you yourself are breaking them. I agree that it is hard to feel like a normal person when everyone around me is reminded audibly and loudly that I am not. I spoke to someone at Dexcom about this and they assured me that I can set them to vibrate. However, I have to do that for each and every alarm. Why would I want to set some to vibrate and not others? Why not one overall vibrate setting? Why not have a system like the old receiver that gives you a vibration warning first, then 5 minutes later gives you the audible if I don't acknowledge it. That seemed a good option. But now I get no heads up before that loud alarm. Dexcom, please listen to all these users here asking for one simple thing we would like to have.
 
Annoying alerts and doesn't cancel alerts with Apple Watch 
I like that I have one less thing to carry around now that the Dexcom can connect to my phone. Most alerts I have been able to customize except for the below 55 alert. Very annoying that one can not silence when the user is already aware where they are and have dealt with it, especially when they are in a meeting, movie theatre, church, etc as others have mentioned. I also have an Apple Watch where I am able to see what is going on without taking my phone out of my pocket and drawing attention, except when I get an alert. When I get an alert, I am not able to dismiss the alert from my watch. I have to take out my phone and do it otherwise it keeps alerting me every few minutes...very annoying! Please fix!
 
HORRIBLE 
Always crashes
 
Sound/Signal 
This app has gone from useful and convenient to unreliable and annoying. As with all of the one star reviews, I am extremely unhappy about the changes with the sound settings. Aside from that, for the past two weeks now I have consistently been seeing the black signal loss bubble on the screen, while the Dexcom device is functioning perfectly. It's as though I downloaded a free trial version of this app and my time limit has expired. The ONLY workaround I have discovered for both issues is to just close the app altogether and revert to carrying the device again. I will say the reliability of the device vastly exceeds that of this app.
 
No control 
This app is really horrible. There is no user control of many functions. Can't set the readings from mg to mmol, no user alarms, no control of muting ALL alarms, scale has only 2 settings, alarms sound repeatedly even after accepting it, no history without connecting online, just simply no user control over important functions and a lack of good functionality for alarms. I too am ready to trash this app and use the receiver. I can dissect it and remove the alarm so it can't sound and use the follow app since I do have control with it.
 
I want my money back to choose another CGM 
I've had T1DM for almost 20 years. I am a classroom teacher. I am a grown adult. I have shared my personal health information with a lot of people because of the 'safety' update. I teach in a school that locked down 3 times last year with the responsibility to help keep our students safe and quiet in the face of danger. How can I receive information if my phone is blaring a crying baby or some other ridiculous alert AFTER I have acknowledged it. I wish I had chosen any other CGM than DEXCOM. I've only had it 3 months and the update came about a month in, and it took a month to get the runaround from support to learn that their ad campaign to help me take control and live my life to the fullest was a sham. This app and sensor duo is more embarrassing and endangering than anything I've experienced since my diagnosis in the 90s. The iPhone integration is decent, but don't be a sucker for the app like I was.
 
Signal issues, high issues 
Entering calibrations causes the next one or two readings to be missed. Randomly misses readings, loses signal (? Indicator), can't make out a reading for extended periods (???). Communication between phone and transmitter needs to be consistent and true; signal interference or iOS communication issues should never come into play or be a reason for an issue. I keep my phone in my pocket or within a foot of me at all times to keep signal, I typically run no more than 2 or 3 other apps and close those when done, I have plenty of memory available on my phone and only have the current transmitter as an option to connect to in my Bluetooth settings. Along with the above, the more recent issues for the past month is the slow uptake on rising blood sugars. I will could be 200+ while the cgm reads steady at 150. This particular issue along with more frequent signal problems has been for close to a month now. Will report to tech support this issue too as I believe it is more a current transmitter issue than my sensors (doubtful 4 in a row would have this occur, never have had these issues in the past).
 
Alarms and low storage space warnings 
Please allow me to turn off the audible alarms. Although I suspect that my iwatch problem is Apple please at least allow the notification acceptance on the watch stop it from alarming on the phone. I've had to go back to the receiver because I cannot discreetly acknowledge the alert in the middle of a bus dined meeting. Secondly quit warning me that storage is almost full. iOS will clear up low storage. There is no way to do it yourself. The alarm is useless and annoying.
 
Watch needs a better complication! 
Spoke with Dexcom- they were not aware that watchsugar app allows you to see your number and the direction it's going in the complication- please update so we can see it in the complication! Dexcom told me that they will look into this if more people call Dexcom to complain... please Dexcom! update the app!
 
Very stable and helpful app 
Always been very stable and works great for me. I love not having to carry my receiver around and having my BG on my wrist. So convenient. The most recent update is even better! I like how it stays silent for the first alarm, but overrides for consecutive alarms. I must be in the minority, but the recent update works perfectly for me. If you set it up correctly, you can do two things: 1) Have all alerts only vibrate. 2) you can have it vibrate first and only make a noise if you don't respond. You have to dismiss the alert within the app. If everyone would just take a second to learn about the new app and the features that are meant to be an improvement, you would see that this app is very well designed and accommodates everyone (the people who like the old app and the people who want to audio override). All in all, thank you Dexcom! Very happy customer here with the recent update, please don't roll back! For those with issues, call customer support and they will help you better understand the features. The current (new) app can be silent all the time, you just need to adjust some settings and I'm sure they should be able to show you how. Not a Dexcom employee, just someone who works by the software industry and is willing to change to accommodate a diverse user base with different needs. Remember: this current update accommodates everyone (those who want silent and those who don't). You just need to work with Dexcom to understand the settings available to you and adjust yours.
 
Apple Watch app crashing 
***1/9/2017 update *** Finally we now have an updated glucose complication that is updated on the Apple Watch watch face. Thank you!! ***Update*** I had to uninstall the app and re download it to correct my Apple Watch app force closing. All is well minus the fact that I lost my last 24 hours of data in the app. This should also be backup up in the cloud. **original review** With the update today (11/1) the dexcom app on my Apple Watch keeps crashing. Please fix asap.
 
Life-Changing App that Lands Shy of Perfection 
Hello, I've been using the G5 app for as long as it's been available and love it, as well as the companion app for the Apple Watch. The ONLY things that cause me to give anything less than full-throated support are the volume controls. Because alerts are allowed to override the "silent" setting on my phone, they directly conflict with the app's otherwise seamless integration with my lifestyle. I definitely appreciate that many people may need this feature, but I would wager that many don't. I suggest that each alert has a user setting to opt in/out of the silence override. Alternatively, as a half-measure, perhaps the UI could be updated to show the alert type from the "Alert" main screen so that the user doesn't need to go into each listing individually to see which sound/vibrate option they've chosen. Ultimately, this app is game-changing, which is why this frustrating feature stands out so starkly.
 
Complication 
Update: Not sure if the alerts were toned down for this update or not, so I'll leave the original review below. The blood sugar complication on the Apple Watch face is a much welcomed addition. I can now use the watch as intended instead of keeping the Dexcom app open at all times. It may seem petty, but a quick glance at my bloodsugar, weather, etc all at once makes for a much nicer user experience than having to push a couple buttons to access. Add me to the list of people not happy with the new alerts. The app needs to be recoded to respect the current sound status. If I have on do not disturb, I don't want my phone vibrating all night long. I have my additional receiver for that. Same with silent mode. My phone should not be bypassing that setting to send out audible alerts. Also, since I'm already complaining, can we finally have the bloodsugar show up on the lock screen with the alert? As well as a snapshot of the reading on the Apple Watch face?
 
Nice update 
The new watch complications make this a much more usable app. Now if they can take these updates and put them in their follow app.
 
Apple Watch complication update!!!! 
Finally!! The long awaited Apple Watch complication! So happy to finally see my Dexcom number with arrow as a complication. A great app just took it to the next level. Thank you Dexcom!!
 
Give us a mute button! 
I love that after countless reviews with a 1 star you guys don't even acknowledge the urgent low sound cannot be disabled on the last update. Give me a break. I understand this might be forced by the FDA, but I thought the FDA approved system was the separate receiver; why can't this app conform to the users requests?!! Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
WatchOS complications 
Love the updated watch complications. Watch app is 100x more useful.
 
Update 
Helps a lot, love the app it makes life easier but the new update makes it to loud especially in class.
 
Silent alarm (still) needs to return asap 
I need the silent alarm back, this is an achilles heel that will cause me to uninstall the app and look to medtronic. update: Still useless, just end up swiping the app closed and going by feel again. I'm going to guess I'm not alone there. We need the choice to have ugent lows, etc. muted or not. Put a parental lock on it if you must.
 
Alarms are terrible 
When I put my phone on silent it is for a reason. Since the new update your phone will continue to alarm louder and louder until you acknowledge it! Very annoying and frustrating. I think we should be able to decide whether or not we want to have that feature on or off. Other than that feature dexcom is great.
 
Great Update! 
Updating the Watch feature so that the glucose reading is displayed as a complication is a fantastic update which makes an essential app just so much better. Thank you for all the effort you put into your updates!
 
New update causes error 
New update causes an error to crash and force me to exit and it forces you to restart the app.
 
So so close 
Update - love the new complication update. Love to see my blood sugar on my watch without a "click". I am leaving at 4 stars because when you dismiss a notification and the alerts still goes off, is intrusive. Also, if I didn't test, and even when I go into the app, it still alerts too often killing the battery on my phone. Love the updates. Keep them coming. 😀 This is a fantastic app and just needs a few tweaks to make it perfect. Love the Apple Watch update. I would love to be able to see the actual number as one of the modules on the actual clock (I think this is called complication). Right now we can see just the Dexcom symbol, which defeats the purpose of having it at all. You just save one step by not having to use the Digital Crown. Push notifications on the lock screen are fantastic, but we need to a way to acknowledge high/low blood glucose there. Otherwise you have to go into the app to acknowledge which gets very annoying (especially days you are sick and you glucose is always high). Still love using a phone as my receiver.
 
G5 finally heading in the right direction 
The complication feature it's something I've been waiting for since the G5 was announced and I got my first Apple watch. The fact that I can look at my watch without pressing any buttons to see my blood sugar just as easily as checking the time is a huge step towards feeling a bit more"normal." That being said, the forced audible alarm for urgent lows is still a very real annoyance. Sometimes my blood sugar drops and levels off at a low point and while waiting for it to come back to normal levels, I'll have to deal with multiple audible alarms and have to go to my phone to disable each time(even for the same occurrence). This still needs to be addressed. Another diabetic supply company said it best..."having diabetes isn't a choice, how we manage it should be." Give us the choice as to which alarms we want.
 
Sharing 
I think you should be able to share your sugars with more than 5 people, but otherwise, it is great!
 
Still not updated, update. 
It is now 2017 and after regular bug fixes and new features this app still hasn't been updated for phones that are now three years old. Still needs an update for ios8? Come on, stop wasting our time, feels like a joke at this point.
 
Great! 
The new Apple Watch complication is a great addition!
 
Life changing 
Great app, does its job wonderfully. This app plus the G5 have made a huge impact on my daily diabetes management. Love the new widget! Only wish is being able to pinch zoom in/out and pan the graph in the app when the phone is set to landscape mode, and be able to write in my own words what food I had when adding a Carbs event (in addition to the carbs value). UPDATE: Love the Apple Watch support!! How about being able to enter BG values through the watch? UPDATE: Hooray for BG and trend arrow in notifications!! This app is getting better and better. Keep up the good work!
 
Still need to get rid of mute override 
The new update is great for Apple Watch users. However you STILL cannot silence the urgent low alarm. This is still a much needed fix.
 
Apple Watch complication great, loud alarms still a problem 
I am so pleased by the Apple Watch complication in the latest update! I hope the watch app will now allow alerts to be dismissed without having to open the app on my phone, but it's not clear if that's the case. Unfortunately it doesn't seem that the issue with the audible alarms has been solved so I have left my previous review below. Thanks for the update, keep them coming!! - The latest update has disabled the ability to silence the app, unless you specifically set each alarm to vibrate only (except for Urgent Low alerts, which are audible no matter what). Before the update I would set my phone to vibrate or Do Not Disturb while at work (or anywhere else I need my phone to not make noise) and turn the silent switch off at home so that I can hear the alarms at night. Now, no matter what sound settings I put my phone on, there are LOUD blaring alarms. Because of this I've set all the alerts to vibrate only, and now the dexcom no longer does me any good at night. PLEASE dexcom, this update makes the app nearly unusable when the alerts worked well before- please fix this!!!
 
Silence the alarms for Peet's sake! 
This update is cool but still fails to address the colossal mistake and massive inconvenience your last update caused. There needs to be a way to silence all the alarms! I am an adult with a career and I can not have my phone making noises while I am at work! This app was supposed to make our lives easier and so far all its done is make it more annoying. I have already been written up at work for the alarm going off which makes me turn the app off at work, where I need it the most because I go low quite a bit from constantly doing physical things! Give me a way to silence the alarms of I'm going to be forced to stop using dexcom when I run out of the sensors and transmitter! This is a disservice to your customers to ignore our feedback and needs of this app! Give us a way to put the alarms on SILENT!!!!!!!
 
Can I see the number if I use the Follow app? 
My son uses Dex and we have a set device for him and I use Follow. Can I get his number on my Apple watch face?
 
The alarm still goes off when I don't have my sound on 
I really don't like that even when I turn the sound off on my phone it still makes noise I really did not like that part of the update. I'm in high school and it goes off. I've had to turn my app off during the day because of that reason. It's really annoying. You should make it an option on if you want it to do that or not. But other that love the app!
 
Hate the new update 
I hate the new update since yesterday I have been unable to get any of my Dexcom information on my Apple Watch. I saw that the new update should work better with the app but I have been unable to access that feature. I also hate that you cannot turn off the urgent low alarm and that the fact any alarm goes off every 5 min even once cleared so I have turned off all alarms but the urgent low because that is not an option to prevent alarms from going off all day.
 
Watch app is great, rest could be better 
The new Watch app is great! Finally you can see your readings by just looking at your watch, displayed just like the time of day. In contrast, the iPhone app hasn't really made it into the 21st century. I suggest the app developers talk to their colleagues in stock markets to learn how to display data over a large time period to follow trends. Data display and handling is miserable. App has the look and feel of a 1980s COBOL program.
 
Really? Listening to your customers? 
Where is the change to the mute over ride feature? Definitely didn't listen to your customers.
 
Need to have a mute button! 
I've been using dexcom for several years now and love it. I work in the medical field and love that I can quickly look at my blood sugar in the few spare seconds I have between tasks. BUT, I hate that the mute feature was taken away. I can't have my phone going off in the hospital constantly. I always silent my alarms and keep my phone in my pocket so I can feel it vibrate but I absolutely cannot have alarms going off. I am also in school and can't afford to have the alarms going off in class, during tests, while giving presentations, etc. I understand that some people want alerts to go off still when on silent, but give us the option to mute it as well. They did not think this one through very clearly.
 
Alerts 
App updated and they still haven't fixed the alarm hack. Apple could easily block this app for breaking the design guidelines. And the UI does not even support 2 year old iPhone 6 Plus.
 
Unbelievable. 
How has Dexcom still not fixed their mistake by making alarms silence-able again? Not having the option to silence the app is majorly inconvenient and bordering on unacceptable when goes off in a meeting, in class, in church, or it causes me to lose sleep nearly every night (I don't need to be woken up because my glucose is 2 mg/dl upside my "high" threshold, and before a previous update, I wasn't) when a vibrate alerting JUST ME would have been perfectly sufficient. How much more negative feedback do you need? Customers spend thousands of dollars on this potentially life saving product, just to have the software updated and changed to something that is all but unanimously despised by customers. They even had the audacity to say that they have listened to feedback in the update notes while in no way addressing the issue that is ruining their product. If this were any other market, Dexcom would be underground. Unbelievable.
 
Silent Alarm!!!! 
You didn’t fix the key complaint—mute override. This app is terrible for anybody with a professional career. I want the ability to control my diabetes with this app, not notify the world that I have a disease.. This app is a disruptor to everyday life!!
 
Bring back the old version! 
I have loved the Dexcom CGM and the functionality with my iPhone. The previous version worked flawlessly...until the new update. The bad - the reminder to recalibrate and check your glucose is relentless. It pops up every 30 seconds and will not stop. You cannot change the settings for the Urgent Glucose Alert - it is set at 55. Further, you can't turn off the alert for it, so no matter what, it will go off. The worst (and why I am considering changing to the Medtronic CGM) - you cannot turn off the noise alerts. No matter if your phone is on silent and the noise notifications are turned off, the app WILL STILL SOUND ALERTS. This is embarrassing to say the least - I cannot sit in a meeting, in a training class, in a movie, in church, etc now without turning off the app completely. What use is a CGM if you can't track all the time? However, if you leave the app open, the app will sound off...relentlessly. I could not be more frustrated with this new update. If Dexcom doesn't update and allow you to turn off the notifications (or AT A MINIMUM, not be able to override Silent Mode on the phone), look elsewhere for your CGM needs.
 
New update needs fix for notifications 
1. I should be able to acknowledge the "Enter BG" alert and then not have to see it again for 24 hours just like it used to be. Either that or have an option to completely turn off that notification. This is important because I wear my watch to sleep for notifications of lows and I frequently get woken up with the need to calibrate. 2. Should be able to dismiss notifications from Apple Watch. 3. Time on the watch complications would be good. That way I know I am looking at current data and not acting on old data.
 
Phenomenal!!! Apple watch complications 
This latest version allows reading glucose information directly from apple watch complications. THANK YOU!!!!
 
Still have to turn the app off at work 
I have to echo what Frustrateddexcomuser said. This is a real problem and I'm tired of having o babysit or turn off my app while in the office. Please fix it.
 
LATEST UPGRADE RELEASED PREMATELY 
The upgrade requires you to unpair the watch. Terrible app! Do not upgrade! You'll have to spend 2 hours on the phone!
 
Please release an update to allow Signal Loss to audible! 
The latest version is good and I would give it 5 stars if it were not for the continued audible issues others report. Please have the app ignore/override the 'do not disturb' when a signal loss is detected meeting the alert criteria. This could be critical at night especially if we are using only an iPhone as the primary device. I sure would love to be able to abandon the receiver and trust the app, but with this issue I can't. I lost signal last night on only my iPhone and it gave me on screen notifications but no audible.
 
aaah! 
Hi Dexcom! What’s up? It´s been six weeks now since you made the App unusable for lots of customers with your “noisy phone” feature. Sure, the rest of the app (and especially the follow app… omg) needs a lot of work too but that’s plain secondary at this point. Right after the update I was stunned how apple let you even do this stuff on their prudent platform. How did you convince them this is necessary? Apple wants to be a health company sure. But an unmutable phone? From Apple? How embarrassing. Nevermind. I really assumed you would fix this issue within days as a result of all the desperate reviews of teachers, cameramen, …and pretty much every other working person. But as weeks pass I really start wondering – are you serious about this? Although hundreds of other reviewers already said pretty much everything, I´m writing my first app review ever today, hoping I can help a little. Other reviews say they can´t understand why people are upset as “we underestimate the seriousness of the condition”. What a ridiculous statement. But that´s not even the point. Nobody likes to be patronized. That’s the point. As others I’m changing the low alarm at different times of the day. So why the hell would anyone need a loud, unmutable alarm at 100 for example?! People who spent boatloads of money for that system want to be able to choose for themselves what settings suit them. At the same time, I’m also sorry for you Dexcom. Of course you didn´t mean to mess this up. You must have been proud of the new release as it´s a “result of requests from our valued customers”. Now the very same customers are upset … crazy isn’t it? It´s impossible to develop an app that suits everyone, right? NO! That’s exactly why there are settings! So I beg you: MAKE IT AN OPTION!!! (or better: just remove it) In many reviews people say they’re thankful for the G4/G5, that’s fine. I´m too. But after one year I can´t believe how you still haven’t picked so many of the “low-hanging fruit”. I am slowly running out of creativity to understand all that. You could really be more transparent about the problems (without revealing stuff to your competitors). What fixes are you even working on? You really need to get to know the range of different customers you have with the G5 better. Or at least acknowledge we are not that silly.
 
Thank You! 
Thank you for listening! As a parent of a type 1 diabetic toddler, that was always our only down side to the app. You couldn't silence all your apps and still get alerts for our little guy. Thank you for listening and making that change for parents like us!
 
New version not good 
I love Dexcom. I rely on it daily now. However, this new update makes it impossible for me to have my Dexcom on sometimes. The update is terrible. I am a full time college student and work part time - I HAVE to be able to silence my phone completely. The only way to do that now is to turn it completely off - but then I don't get Dexcom readings so that's useless. I have all my settings turned to vibrate (minus urgent low) which is great during the day but at night... I want the sound on as loud as possible. There needs to be an on/off to push notifications through. I'd love it at night, hate it during the day.
 
Audible Alerts Don't Bother Me Too Much, a Non-Functioning App Sorta Does 
Since updating to iOS 10, the app will only receive around 80% of the readings from the sensor. Dexcom claims iOS 10 support, however the issue arose the moment I upgraded. I've resorted to carrying around my G5 receiver, which does not have any issues at all.
 
Terrible app updates 
Every time this app updates it just gets worse and worse. It's like they don't have any actual diabetics around to ask if the update makes sense or not. The new alerts are ridiculous and there is no reason I should have to go into the app to clear an alert. If I clear an app from the home screen it means I've seen it and okayed it. Why does the app force me to go into my phone, open it up and click ok? It is aggravating and demeaning. I've clearly seen it and I know what to do. If they wanted extra steps they should add an 'I'm an idiot filter' for those who'd like to use it . For me I'd like to go back the the way the app was 6 months ago when it actually was useful.
 
Nice app, but recent update has caused irritating behavior 
It's disappointing to see so many people upset at the mute override update, but no updates to fix it yet. The app's average rating is a 1 1/2 star, which says a lot about how poor that update was. Working for a health technologies company where I build apps, I would think a fix (if even a temporary one) would come much sooner. Ironically, this causes a disturbance at my work as well. Beneficial in some areas (like urgent low) but it needs to be able to be turned off. And there doesn't seem to be any word on if they are even working on a fix yet. This is undesired behavior from the app for lots of people.
 
Not fast to use 
Hey thanks for creating the app. Please make it less taps to enter blood sugar and insulin values. Do you really need to confirm the values every time? Also the graphics and icons look like they were created by a child.
 
TERRIBLE UPDATE!!!!!! 
I hate this app now because of the latest update. I have been a type one diabetic for 3 years now and this app was awesome. Until the update. Now when I'm in school or at the movies, the app notifications go off and it's not quiet. Super loud. Like saying "HEY WORLD! IM A DIABETIC AND I WANT YOU TO KNOW THAT!!" It is super interruptive and annoying. Fix this problem and I'll fix my review. Thanks.
 
Mute override ruined this lifesaving app! 
I have had diabetes 20 years. This app has changed my life for the better. However the fact that you cannot mute it has made me close out of this app numerous times for important meetings, movies, etc. yes, we need to know when we are low but we need an option for mute or vibrate! GET RID OF MUTE OVERRIDE!!!!
 
Mute override has to change 
We love this app but can't stand the new update where you can't turn off the urgent low and system alerts!! My daughter is 14 and has had type 1 since she was 10 months. She is able to feel lows and treat during the day and doesn't need the loud alarms distracting her!! It is getting her in trouble with teachers, is extremely annoying, embarrassing and distracting during class, chapel, church, movies, interviews, SAT testing, funerals, etc. Please change this right away or we will not be able to use this app. I can see how it is helpful at night, but there has to be an option to turn on and off when needed.
 
Was an amazing product. 
This was once an amazing app as it helped get my sugar under control. Now with the mute override feature, I am no longer able to use my dexcom. Instead of paying attention to my work I would have to watch my sugar like a hawk to prevent it from triggering an alert that doesn't follow my silent or DND preferences.
 
Dangerous 
This is a dangerous update. By removing the option to silence an alarm as you'd silence your phone, it makes this app unusable by people like me (I will lose my job if I have an alarm interrupt production). Newest OS update causes the alerts to be played even when the app is closed. Had to kill Bluetooth in order to stop it from going off at work. Forgot to turn it back on in the evening and woke up in the hospital on Thanksgiving. Had my family not been expecting me, might not have woken up at all. DexCom forces a choice between employment and health. I'll find a better option, no more DexCom for me.
 
Game changing CGM 
For the love of science, please add BG value in pop up notification 🙏🏾🙏🏾🙏🏾 Thank you for all you do. ^**11/29/16** not much to add other than what most have already said here. 24 year T1 diabetic and this has made my life so much easier! Suggested improvements for iOS app: •provide BG in notification alert •allow scrolling and viewing of trends within portrait view •allow more than 24hr trend view (48,72, 1 week?) •not sure if it's Health/apple app issue but allow real time Health app view instead of 3 hour delay. Apple Watch •useful complication w/trend arrow and BG value •option to scroll trend directly on Apple Watch app Thank you for your hard work here!
 
Make alerts silent again 
I loved the old update that allowed me to silence the alarms and not get alerts on do not disturb, but the new update is awful. It has gotten me in trouble at school (I'm a junior in high school) because of the alarms that go off even when my phone is in do not disturb mode. They alerts continue and get louder which is highly inconvenient. Bring back the old version!!!
 
Dexcom review 
Don't like ANYONE telling me how to manage my Diabetes! I always felt the vibration under my pillow when the Dexcom THOUGHT my sugar was low Without waking my husband! Always got up to check my blood glucose and of course it was higher than the Dexcom meter reading.
 
Needs Option To Mute Alerts!!! 
The fact that alerts come through when the phone is muted or on do not disturb is an improvement but an option to silence alerts is absolutely needed. Like when I'm in an office meeting or working with clients. Vibrate would be more than enough to get my attention without having to also alert all my co-workers. Also the watch app now has problems - it needs to catch up to the app before it displays reading which sometimes takes a few minutes, basically rendering it useless.
 
Terrible update!! 
Don't like not being able to control volume or mute alerts!!! Very distracting during work and embarrassing at movies. Now I have to turn off Bluetooth to silence alarms which defeats the purpose of having CGM.
 
Alerts 
This app is amazing. However, the number of times that the Low and Urgent Low alerts go off need to be changeable to more frequent times. If you DONT hear the first one, you won't hear the next when you're in deep sleep. Please change this!
 
Fix for sudden increase in sound 
I love this app overall, and the way it helps me know my levels throughout the day. However, I will have my sound set to a lower level on my phone, and a low or high alert with this app will go off at TOP volume instead of where the volume is set. I appreciate the vibrate option, but I work in an environment where I need the sound but also not at top volume so that it could be disturbing others around me. As soon as that's fixed, I'll be sold on this app!
 
Love the sensor 
The sensor is very accurate, I had use other brands in the past and this one is the best so far, but this app is incredibly annoying, specially at work. If there is not an update soon with the sounds I might have to delete it
 
Great App! Bad Update with Mute Override 
The app is great in all aspects except for the new mute override feature. There is a reason for the silent/vibrate switch on the side of the iPhone. It is to silence your phone from alerts, especially during important meetings, presentations, church, weddings, funerals, and certain high school & college classes. I (and other diabetics) see this as a step backwards because I now have to choose to 1) turn off this app or phone and not monitor my BGs during these events. 2) Risk getting in trouble at work/school where you are asked to leave if you can't silence you phone(e.g. College class with 300+ people). Please add the option to allow the iPhone silent/vibrate to fully control ALL alerts this app generates. I understand some diabetics may accidentally enable this switch and will still want to get alerts; however, some of us use this switch for its intended purpose, which is to silence our phones at appropriate times. I see this as a step backwards as now I am required to make a choice to not monitor my BG for these events. In the past I could just enable the silent/vibrate switch and monitor my BG discreetly. Since my company requires phones to be silenced during important meetings and presentations, I will not be able to monitor my BGs during that time. Please consider this in your next release. Can you at least add an option to enable or disable this mute override feature in the app settings menu?
 
Irritating as Heck! 
Now that I can't silence my phone, I'm waking up my sleep-deprived college roommates all night. The vibrations alone were enough to wake me up when my blood sugar was low at night, but now they have to suffer with me. I've been yelled at in class for having my phone get notifications, even though they are medical. They're disrupting class and going off during important exams. My professors ask why I can't put it on silent, to which I have to reply ¯_(ツ)_/¯. Not only that, sometimes my signal is lost and the app won't tell me for a solid couple hours until I notice that I haven't gotten any notifications in a while and open the app. Even though it's been running and should have told me after 20 minutes that my signal had been lost, it didn't tell me anything. Please bring back the option to silence the alerts as it's become a pain to both me, my roommates, and my classmates.
 
Terrible Update 
The new update is not worth it. They removed the silent and vibrate options for low alerts. This needs to be fixed. I don’t want my phone providing audible alerts during meetings, at the movies, or whenever I put my phone on silent. If not fixed, then I guess I’ll have to stop carrying my phone around or just remove the Dexcom sensor. This update makes me want to remove this thing.
 
Worst update ever, I wish they had a brain 
Because of the nice Dexcom hacking skills with the do not disturbed iPhone feature I now have to turn off my iPhone or change my thresholds for meetings, or other events. Which defeats the purpose of the CGM, and me being able to use my phone. Let us manage our own alert sounds, volume and mute settings. We are not stupid, and stop blaming it on the FDA because is not true.
 
Life saving device!!!! 
I love the dexcom G5 mobile app. Not having to carry a receiver around is very helpful and checking my blood sugar on my phone is much more discrete!!! It is super accurate as well.
 
Great with room for improvement 
LOVE the information and control the CGM app offers. HATE that no matter how many times we try to trouble shoot we can't seem to get the app to share info using his phone data. It works great when he is on wifi. FYI the playground and soccer field where we desperately NEED the info has no wifi. We bought him his own phone plan just for this purpose. (Yes we have checked with the carrier, his data is setup to cover. The app is just failing to send signal without wifi) All to no avail if the app fails. Please fix it. Thanks. Mom
 
Vibration option needs fixing 
Hi. I love that Dexcom exists but there are a couple of things that need improvement. There needs to be more than one vibrate option, I.e. One vibration for highs and two vibrations for lows for example. Just like your iPhone you can set different vibration patterns for different alerts, same thing here. Right now Dexcom app vibrates twice in a row for both Low and High alarms. Frustrating as then I have to take out my phone or watch to see which alarm it is and how to treat. Also, the app is funky after the update. I click OK on the high glucose and it's supposed to not let me know again for 1 hour but it keeps letting me know! Ugh! Like very few minutes. I agree with the other commentors, let us decide how to receive the alert. I know there are lawsuits threats but come on, these people don't need hand holding, they should be able to read your paper alerts you mail and include in the shipments. We all shouldn't have to suffer due to a few people who like to stir the pot.
 
Absurd Urgent Low Glucose Alert 
I love the convenience of having the Dexcom app track my blood sugars. It makes monitoring them very simple. However, I liked the app a lot more BEFORE the update. The fact that you can't silence the Urgent Low Glucose Alert is absurd. What the hell are you supposed to do when you NEED your phone to be silent, like in church or a funeral? I've also discovered more recently that there are other alerts that randomly make noise even when the phone is silenced, like the alert for when Dex needs you to enter in a new blood sugar because it hasn't calibrated correctly. It totally freaked out on me when I was talking to my boss this week — annoying. I know low blood sugars below 55 are serious and need to be addressed immediately. However, during the day, I'm conscious and awake, so I can pay attention to my phone and see if I'm low. At night, I sleep with the Dex receiver that vibrates very loudly for low blood sugars. I like to sleep with my phone on silent so I'm not awoken by emails and texts. I've already contacted Dexcom Support twice about this issue. They don't have any advice on how to troubleshoot this problem. The second time they actually ignored my email. I honestly thought I was the only person who thought the alarms were ridiculous until I stumbled upon Apple's app reviews. I'm so glad I'm not the only one who thinks this is stupid. Dex needs to release a new update with vibrate as an option for Urgent Low, just like for the other alerts.
 
Silent alerts 
While I understand the need to hear all alerts, I cannot have my phone going off at work and church. We need the option to have silent alerts.
 
I don't really see why you changed anything. At all. 
This is updated on top of this review. I have been reprimanded twice now from my job due to "phone use" and I explain to them there is no other option than to leave it on. You're about to lose a customer Dexcom. You shouldn't be the one that says when my phone should or should not go off. FIX IT. I own the Apple Watch and pair it with the app, it's absolutely wonderful. Originally, my phone wouldn't do anything and only my watch would tell me, but now, my phone is screaming in my pocket along with the watch and it is quite irritating. It's also not a normal vibration from my phone. I don't like that either. One way or another, 1.) fix the "always noisy" 2.) I don't need both of my devices notifying me and there is no way of changing that. I only need one thing letting me know. Unlike EVERY other app on my phone, I don't have an option. On the plus side the new Apple Watch view is good.
 
New urgent low feature 
The fact that the new urgent low feature is not mutable and can only be lowered to 55 is awful. I sometimes need my phone to be quiet, and allowing me to turn this off was essential. I am extremely upset by this, as now I can't use the device at school or during midterms and finals. Additionally, at a level of 55, the margin for error makes it so that if you are around 70, it might say you are urgently low and you can't mute it, which is unacceptable. Please allow users to turn of any volume notifications.
 
Alerts/sounds not working 
Terrible update. Don't do it. Now all alerts are giving me the same sound and I am sleeping through low alerts. Each alert is set to be a different sound but they are all giving the same one. Very disappointed with the update.
 
Useless 
I can't even access it because it's not accepting the barcode or the SN. It keeps telling me it has to start with a 4, yet mine clearly starts with a 6!
 
No silent alarms! 
I have been using Dexcom for three years now. I loved when the switch to the iPhone and I was in able to send everything to my Apple Watch. With that option I could have my phone completely on silent but always get alerted by the taptic engine on my watch. Because I work in video I can't have alarms going off why I'm filming...with the new update I have to turn my phone off while filming(a majority of my day). This new update has turned my transmitter into an annoying worthless insert while I'm working. I hope Dexcom reads these reviews and updates again to allow us to silent these alarms. As another review says..."we are not all children." Not having the option to silent the alarm is a killer for the app. Otherwise it has been amazing!
 
Needs a dozen bug fixes 
There are simple bug fixes they haven't addressed since day one it came on the market. I've told their Dexcom support people and they have supposedly made a report and told their higher ups but the simple issues still exist. That was over a year ago. And what's more? They come up with an update recently, that makes stupid changes to sound effects, like the fact that it can still make noise when on silent. WOOPTY FREAKING DO! Make it so that it can be more fine tuned, instead of a one size fits all respect! I don't feel like a medical device this monumental should have such huge issues within its software, it's just appalling in my eyes. I was told that they can't make changes to the appt, without making changes to the screen thingy that comes with your cgm that you don't have to use if you use the iPhone appt. The tech person said they would have to change that little machine too. And that everyone would have to receive that new machine. Well that's obviously not true because they came out with updates on the sound recently. The simple bug fixes should have been noticed and changed long ago..... How about the low alert number being only as high as 100. I want it to be higher like 130 instead of just 100 as the highest alert low option. Because at 80 I can't drive a vehicle as it's to dangerous and I'm not able to control my body as well. When I'm 100 I'm usually on the way to going much lower, it's never 100 and "going side ways" arrow. How about the urgent low alert number being only 55, that's ridiculously low for some and I start having breathing and sight issues at that point! Make it higher! How about the fact that the re-alert rate for highs or lows has a 5 and 10 minute marker, but they DON'T WORK! When trying to choose the 5 minute mark, it swooshes to 0 minutes (and why even have the freaking 0 in the first place? Stupid.) When trying to choose the 10 minute mark because the 5 doesn't work, it swooshes to the 15 minute mark. Hence the least amount of time you can make it alert you is 15 minuets between alert notifications. If your going low you know that 5 minuets can make drastic changes if you've over dosed. And say your dropping but the drop alert isn't triggered. How about the fact that it grays out sometimes and I have to restart my phone to get the glitch to not be there any more. When the appts grays out it's like when the phones about to go to sleep and the screen turns grey first, but it only happens in the appt and nothing in the appt is press able. Even when you exit and pull the appt up again. It happens when multiply alerts come at once and the iphone can't handle them along with the other things it's thinking about. I have the iPhone 6s. This shouldn't happen. I was advised by the tech support to uninstall and reinstall the appt because maybe the new firmware didn't go with the new update, but this doesn't have to be done with other less important appts. Unacceptable. When my little pod thing was getting to the end of its battery life and I was on vacation, I knew I had two weeks left on it before it died because it tells you at like 6 weeks then 3 weeks then 2 weeks. I would be home in a couple days and would change it when it died. But then it was time to change a sender as its 7 days was up and I changed it and when I pressed restart senser, it said replace pod thingy. But I had at least 2 weeks left on it and it was making me replace it! I tried many things to out smart it like typing in the same serial number for that same pod thing and it would work for a minuet then glitch out and say replace it. So I had to go for days without it which was like living during the 17th century for 5 days. Sometimes the sound won't shut off when there is an alert and I press the phone button that are on the side of the iPhone. The volume on the phone can be set to medium or soft and alerts still come in extremely loud as if the phone volume is turned all the way up. This is incredibly annoyed at night when your phone is right on your pillow. And no it's not on silent or whatever the new pointless update involved. You can set alerts to alert you every hour or two hours or three hours or whatever. But it doesn't register with what you think you're setting it to. I have mine set to two hours right now but it really alerts me every half an hour if I change it to three hours it will probably alert me once an hour. So the time markers are not equivalent to what they actually say.
 
Completely Unreliable 
Despite the new iOS that solved the nighttime failure, this app continues to be unreliable. It has been working less than half the time for the last week. I've deleted and reinstalled the app, re-connected to the transmitter, etc.; still it fails. Better no app than one that is so unreliable. I will report it once more and then give up and use the latest receiver.
 
Need changes for urgent low alarm 
Overall, this is a great app and I love being able to read my blood sugar on my phone. However, the latest update is a big disappointment. The inability to silence the urgent low alarm is incredibly frustrating. I understand the health concerns behind doing so, but there are times when either a)my phone must be on silent (work meetings, etc during which I rely on the vibration alarms only) or b) the cgm is not reading accurately and the urgent low alarm is not correct. I really hope Dexcom provides another update and gives the users the option to put the urgent low alarm on vibrate.
 
Lousy Update 
I have been a diabetic for 44 years. Dexcom was a godsend with its super accurate sensors and easy iPhone interface. Then the company decided to eliminate silent alarms, as if we are all children, so no matter where you are--at a movie, giving a lecture, on an airplane--if you don't respond to an alarm within a couple of minutes, you get an audible alarm that gets louder and louder until it hs irritated everyone around you. There is no user control over this, and the wonderful convenience for me as a college professor of being able to pop a piece of candy in my mouth and keep talking has been eliminated; now I have to pull out my phone, access the app, acknowledge the alarm, and then explain to my students what is going on. Peopel in movie theaters especially appreciate when I have to activate my phone, share my bright screen, all because Dexcom has suddenly decided it know best. My only alternative is to turn off my iPhone completely, thus losing the benefit of having the sensors in the first place. I switched to Dexcom two years ago after more than a decade with Medtronic sensors. If Dexcom doesn't fix this problem and decide to let adults be adults, I'll be switching back. Provide the option of an automaticly audible alarm, but for the rest of us, don't add to the burdens of beign diabetic.
 
Mute override ruined this lifesaving app! 
I have had diabetes 20 years. This app has changed my life for the better. However the fact that you cannot mute it has made me close out of this app numerous times for important meetings, movies, etc. yes, we need to know when we are low but we need an option for mute or vibrate!
 
DONT UPDATE 
This update is terrible!! We want to be able to silence the alarms. I can no longer use it in schools, stores, movie theaters, etc. Also Apple Watch doesn't work with it anymore! I bought that specifically for this! CHANGE TO OLD VERSION!
 
Hate the update 
Please change it back. No longer able to control volume for urgent low alerts. Have not opened the app since last update.
 
ALARMS 
I hate that with the new update you can't turn off the alarms. For a while I thought that something was broken in my phone because the alarms kept going off, but I soon realized that the app had simply updated. Even thought the update has vibrate mode for the alarms, it is very inconvenient and distracting to everyone around me. I need the alarms to be off during school because (although the alarms are allowed to go off during school) it distracts EVERYONE around me when they have to turn around my alarm blared in the middle of class. I am even considering not using my sensor for a while simply because of the alarms. Please turn this feature back on!!
 
Hate the new volume settings 
Give us an option for the high alert volume. I understand the need for important alerts. But if I'm just sitting in bed playing on my phone, I don't need a heart-attack-inducing high volume alert a few inches from my face. PLEASEEEEEE give me an option to say how often it reminds me to enter meter bg value. I DONT NEED REMINDED EVERY 5 minutes! It's annoying and ridiculous. I'm about to turn off all notifications. Which defeats the purpose!!
 
"Do not disturb" for a reason! 
I am not new to Dexcom. I absolutely love the data I get from the CGM. It is the most accurate system available. I love being able to use it to manage my diabetes and have for almost 5 years. However, this update is the first time that I have been in a position where I wish I didn't have it. Today I will be going to my usual church worship services and will not be able to leave my phone on. I am so disappointed. When I choose to have my phone silenced by simply flipping the switch or scheduling a "do not disturb," there is a reason. I like to be able to still look at my phone to check my bg, but not disturb myself, and especially others by audible alerts. The option to go into the app and change the setting, to each alarm individually is a poor excuse for a app that is supposed to make life easier. I am actually going to have to turn my phone completely OFF during my worship services- a much more dangerous medical situation than simply checking discreetly and frequently during church meetings. Then have to remember to go into the app afterward to change all settings again. Unacceptable. Very unhappy.
 
New Update Notifications 
It should be at the discretion and responsibility of the user to decide the frequency and how notifications are delivered. I don't want my notifications to be audible, regardless of how low my sugar is. I keep a steady eye on my progress at all times. What is not acceptable is audible chimes which can't be turned to vibrate, or adjusting the frequency of disruptions. Please fix this and give users a choice. I understand many diabetics are irresponsible and no compliant, but don't punish those of us who are responsible enough to take care of ourselves.
 
Alarm System needs FLEXIBILITY!!! 
There are times when you either know what your glucose level is and do not need to be reminded OR you are in a position where a reminder is useless. I had to remove the app just to shut it up! How hard would it be to provide a silent mode? If it doesn't trust you to un-silence at some point, provide a time interval, increments of 2 hours up a max of 8. Default 2! Even display a disclaimer saying it's not our fault if you die in silent mode.
 
Great App! Bad Update with Mute Override 
The app is great in all aspects except for the new mute override feature. There is a reason for the silent/vibrate switch on the side of the iPhone. It is to silence your phone from alerts, especially during important meetings, presentations, church, weddings, funerals, and certain high school & college classes. I (and other diabetics) see this as a step backwards because I now have to choose to 1) turn off this app or phone an not monitor my BGs during these events. 2) Risk getting in trouble at work/school where you are asked to leave if you can't silence you phone(e.g. College class with 300+ people). Please add the option to allow the iPhone silent/vibrate to fully control ALL alerts this app generates. I understand some diabetics may accidentally enable this switch and will still want to get alerts; however, some of us use this switch for its intended purpose, which is to silence our phones at appropriate times. I see this as a step backwards as now I am required to make a choice to not monitor my BG for these events that will require silent phones were previously, I could just enable the silent/vibrate switch and monitor my BG discreetly. Since my company requires phones to be silenced during important meetings and presentations, I will not be able to monitor my BGs during that time. Please consider this in your next release. Can you at least add an option to enable or disable this mute override feature in the app settings menu?
 
Plz, as a struggling college student, plz 
In college, parents only let me move out because of this app. Lowered my a1c drastically. Love Dexcom and their cgm. However, living with a roommate makes the noise override incredibly embarrassing and annoying. Please stop the noise override so I can stop worrying about waking up my roommate every night.
 
Good but needs improvement 
I've been a Type I Diabetic for a couple months, actually, and This app is really cool and very helpful, too, and I don't know how my parents could live without it, because it gives all my info directly to my parents and my doctors. But please fix the audio of the alerts, if I'm drawing, and listening to music, and it goes off, it gives me a horrible headache. It lowers the volume of the music, then blared in my ear, and then goes back to being silent for the next five minutes like nothing happened. Please fix this. It disrupts my day and my classes, everyone just looks at me like I left my ringer on in class, when it's off. I'll go into do not disturb and turn my ringer off, but it'll still go off! I've said this too many times already, but please fix my predicament.
 
Seriously? 
If I wanted sound in the first place, I'd have my phone OFF silent. Thanks for forcing me to remove all notifications from this app to avoid the horrible horrible alerts.
 
My thoughts on improving the newest update 
I would like to thank everyone at Dexcom for the amazing software/hardware they develop to make my life as well as every other diabetic and their families. Overall I give this application a 5/5 as it has improved my day to day life and A1c results dramatically. The one thing that I don't like about the update is that we are not given a choice to have the alarms not override our phone if we choose it to be muted. The idea is great as many children/adults using this application can easily forget to unmute their phone before going bed or in situations where a vibration alarm would not be enough. Having the option would definitely fix my complain with the new update.
 
Alerts are horrible, loud and can't be turned off 
I've reported the issue with not being able to use silent or do not disturb with the app, but Dexcom has said they do not see it as an issue, and do not plan to fix it. It is incredibly embarrassing and rude to have a phone make loud beeping noises during important events like weddings or funerals that you can't turn off. I was able to restore to the previous version of the app that respects silent and do not disturb modes.
 
Just a little fixing needed... 
Overall I love the app. There's nothing wrong other than the need for a silence option to come back. I can get in trouble for having my phone at school and I need to be able to silence my notifications. Bring back the option and everything will be perfect!!
 
THIS WAS A HORRIBLE IDEA 
This is the first review I have ever written, which says how much I hate this update. I'm 21 and have been type one for 10 years. I have used dexcom app for over a year now and LOVED it, but now with this mute override I am close to deleting the app. First off I lost work because of the update, because I can have absolutely no noise from my cell phone during work and of course a simple "enter bg" sounded like a fire alarm. So of course my phone goes off and I look disrespectful and unprofessional. Secondly, I called dexcom technical support and they said they reason they implemented this was for "safety concerns" but told me out right a lot of people hated the update. I would have to manually go into the app and change them all to vibrate (except urgent low) and even when I did want noise I would have to go change them to sound again. But the risk is too high that I can never put them on sound. Which actually makes it more dangerous for me so the safety argument goes out the window. I'm livid about this update and hope you can see the overwhelming dissatisfaction and will make quick changes.
 
Deleting 
I changed my Clarity password and the phone app can't handle it so I had to delete the app after spending a good 45 minutes on 2 calls with tech support, to no avail. Now, if I reinstall, I'll have this audible alarm nonsense to deal with during meetings with executives. I don't think so. Not much reason to have the G5 if I can't also have the phone app. It's the reason I switched from using Enlight. This was an incredibly shortsighted decision on Dexcom's part. I would hope an update will be posted within weeks to remedy this or they're going to start losing business.
 
Idea... 
When the bgl goes below or above the set perimeters the should be an emoji.
 
The alert update is insane 
There is no way for me to discretely manage my diabetes with alerting the entire floor or meeting room at work that there is something wrong with me. I end up just disabling Bluetooth so the app doesn't receive anything, which completely defeats the purpose. Even after I e treated, it still takes time for my sugars to come back up, and I get increasing alerts for the entire period. Unacceptable.
 
Horrible 
I would give 0 stars if I could. Silence all alarms. You can't be in class or meetings and have these alarms go off. Fire whoever let this update go live. All this promotes is shutting down the phone to shut off alarms.
 
Beware of new version 
1. Diabetics already have a loss of control. To take away our control in our management is hard for us. The new update makes it impossible to turn off urgent alarms. And to turn other alarms on and off you need to go into settings and change to a vibrate only mode. It even bypasses airplane mode and silent mode. This new version makes it hard to be unnoticed in church, school, work meetings, or any other situation where autonomy is desired. Bring back the old one please! I also cant believe Apple allowed them to bypass all their hardware features. I think Apple should review this as well!
 
I don't really see why you changed anything. At all. 
I own the Apple Watch and pair it with the app, it's absolutely wonderful. Originally, my phone wouldn't do anything and only my watch would tell me, but now, my phone is screaming in my pocket along with the watch and it is quite irritating. It's also not a normal vibration from my phone. I don't like that either. One way or another, 1.) fix the "always noisy" 2.) I don't need both of my devices notifying me and there is no way of changing that. I only need one thing letting me know. Unlike EVERY other app on my phone, I don't have an option. On the plus side the new Apple Watch view is good.
 
App crashes and slow to update on Apple Watch since update 
The new update has some issues on my watch and phone: 1) App crashes every 2-3 days 2) if you open the app on iPhone while the alert is still playing, the app crashes. 3) The Apple Watch app is very sluggish to refresh the data to current. Sometimes it simply doesn't update. The performance is significantly worse than the previous version. 4) calibration alerts should not be audible after the first time. Feature requests: 1) force touch the Watch app to force an update. 2) enable a way to acknowledge an alert from the Watch vs. having to dismiss on Watch and acknowledge on phone (when the Watch is being worn). 3) enable adding BG values from Watch
 
Please Fix! 
Hi. My names Tyler. I'm 9 and in Elementary School. In class, my CGM always goes off! So please make an icon to see if you can silence Dexcom. Every time it goes off in school, all my classmates stare at me! I also miss out on schoolwork... So please! PLEASE!! Make it so you can silence Dexcom. Thank you.
 
Good, but still needs work 
Just changed from G4 to G5 cgm and love being able to see my bg on my phone. Would like to see app optimized for larger iPhone screens, integration to Apple health, chart in iOS widget, Apple Watch face complication showing last bg reading. These should be basic first version app items, not an after thought. ***After using this app for a while, the option to disable all audio alerts is irritating, have had my phone go off in middle of meetings, which is very annoying.
 
Give us a mute button! 
Who in there right mind thought it was a good decision to remove the mute all?! People are can be adults and make the decision to live like they have for years without Dexcom. Making this not completely mutable is insulting, wrong, and could even be a safety concern for people depending on their jobs. MAKE IT MUTABLE AT ALL TIMES! It's nonnegotiable!
 
App gets me into trouble at work 
I'm in the same boat as most of the recent reviews, the noise issues have caused me a lot of stress and anxiety and trouble. I am okay with the urgent low glucose noise override, I feel that's absolutely necessary. But when I set my alert for a high to remind me once an hour and I'm in a meeting at work and every FIVE MINUTES my phone vibrates and beeps despite being on silent and set to vibrate only is so humiliating and frustrating. Please hire more developers, please show us that this company isn't greedy and we aren't funneling our cash into the CEO's pocket. Please hire some more developers, my wife is a developer & we will move to San Diego if that's what it will take.
 
Embarrassingly bad 
Terrible UI, unattractive interface, difficult to configure, slow response time, confusing alert settings. Flat out embarrassing that these issues have not been improved after more than a year, and the last update actually made the alert settings LESS clear to configure. However, you can read your CGM on your phone, so it accomplishes the basic goal. Unfortunately there are no other choices so we are stuck with this until Apple's Health API eliminates the time lag for 3rd party apps to access CGM data.
 
Alerts here too 
Add me to the list of people not happy with the new alerts. The app needs to be recoded to respect the current sound status. If I have on do not disturb, I don't want my phone vibrating all night long. I have my additional receiver for that. Same with silent mode. My phone should not be bypassing that setting to send out audible alerts. Also, since I'm already complaining, can we finally have the bloodsugar show up on the lock screen with the alert? As well as a snapshot of the reading on the Apple Watch face?
 
Piece of Mind 
The Dexcom G5 and the mobile app help give us a piece of mind throughout the day. It is a huge help when our 9 year old son is at school, playing sports, sleeping and just being a kid. It's a huge help in monitoring and managing his diabetes.
 
Make profiles 
This app need profiles similar to the one in the original device but can be edited by the user. Also. The profiles should include not only the tone but when. Like a profile with vibration repeating every hour for high above 200. And another profile can be a tone I choose for high above 180 repeating every 30 minutes. The first one would be for something like a class so I do not want everyone to turn around and look at me. The second one would be for bedtime for example. Like for each profile you can set as a user all the alarming settings. Now I have to change all the tones to vibrate before entering the class and go back and search for the tones when I get back home. This is so annoying. I really preferred being able to make it silent or do not disturb mode but this should solve it
 
Give me back my sound option 
I will say I LOVE my dexcom! But, I wish they didn't take away the ability to turn it down. It's so annoying when I have my phone on silent and the app starts screaming at me to "Input a BG Meter Value", which to be honest is not worth the loud noise. I enjoyed being able to turn my phone down in class, meetings, and when I went to bed. Now it's just a nuisance. Please bring back the option to silence it!
 
Poor Update 
I check my phone all the time for alerts & monitoring but the inability to silence all alerts is frustrating & causing issues for me when it needs to be off. We should have the ability to silence or depend on the vibration notifications when our phones are silenced. The app should not be able to override phone settings. I do appreciate the app & it does help me be a better diabetic & have more control but as a person who works in an office & has meetings often this feature is very frustrating.
 
Quiet? 
Love my Dexcom and the app. Super helpful and fits well in my life. The vibrate setting is good, but it should be an option for the first time calibration. The last two times it has interrupted meetings and interviews by progressively getting louder. Some of us just need it to be silent during the day. There is nothing more obnoxious and embarrassing. Especially when it isn't vital. Also would like this option for urgent lows for the same reasons. I for one am not worried about feeling the low or the vibrate. Would be nice if there were daytime and nighttime alert settings. I want more volume at night than I want during the day.
 
Noise alerts on silent is NOT okay and make a widget please!!!! 
Why am I no longer in control of this app?? I am a college student and I need to have my phone on silent when I'm in class. I have already had my phone go off in class which was disturbing to my peers and embarrassing for me. And I can't even fix it by turning the volume down because the app just turns it up. That's not okay Dexcom. Don't force people into this change, make it an option. 2) The thing I want most from this app is a widget so I don't have to open it to see my blood sugars every time. 3)The ringtone choices are terrible. Please get some new ones that are normal, like the iPhone ones, none of this baby crying or fire tuck stuff.
 
I used to love this.. not anymore with the update 
I am really disappointed with this new app update. It's really hard now using the G5 app with being a college nursing student. It's so embarrassing when I'm with a patient in the hospital and ear piercing audible beeps come from my phone. It is not professional at all. It's as equally embarrassing when I'm in a lecture hall with 200 students and they all turn their heads around at me. I have come to the point where I have shut off my alerts. This is becoming a huge inconvenience. Thinking about deleting the app and using the receiver again or trying out minimeds new pump and sensor. Dexcom get your stuff together please.
 
ALLOW US TO TURN OFF THE SOUND!!! 
With this new update, you can't turn off the sound... no matter what. The app overrides all phone settings and will beep/buzz at inopportune times. I've almost stopped using it completely. Developers take note: when I silence my phone I NEED MY PHONE SILENCED!!!
 
Essential app 
Glad this technology is available bcz it makes life that much easier. Wish the app wouldn't alert every 5 min despite being set to alert once an hour
 
Bad update 
Everyone saying that they don't understand why people are upset and that the update is just for out safety: please speak for yourself. I am a college student and I have long lectures, other roommates to worry about etc. my phone must be silent. I was extremely on top of my diabetes alerts before and I do not need this new update. It is annoying and has put me in many embarrassing moments. If you have a life where you can have alarms blasting from your phone whenever then that's great for you, but I don't and I know tons of other people who agree. Switch it back
 
New update causing problems 
As a graduate student who is in class most of the day everyday, not having the option to silence the alarms during class and exams is not acceptable. It used to be so easy to just switch my phone to silent at these times and not worry about it going off, but now I either have to shut down the app completely or shut off my phone completely. Please bring the option of silencing alarms completely back. I understand that it is safer to have them on at all times, but there are certain situation, especially for adults using the Dexcom, that it needs to be silenced throughout the day.
 
New Revision: Very Obnoxious 
Add me to the list of those who want the previous version back. I don't want a loud alarm announcing my low blood sugar to the whole office. Let me set the volume as needed. I'm turning off all the alarms I can. Does The new Mini-Med cgm allow the customer to have control over the alerts?
 
New version is a mess 
Hate that the calibrate notification pops up endlessly until you enter a blood glucose. Hate the iPhone volume settings are allowed to be overridden by an app that I can't even make adjustments to. Please give users more customizable alert options. I can't have this app blaring in a meeting even when my phone is set to vibrate. That's why it's on vibrate! Bring back the old version!
 
Apple Watch app is gone--new alerts are awful 
It's fine if some users want the override, but give us the option to have it or not. And what the hell happened to the watch app??? It's the reason I bought an Apple Watch.
 
GET RID OF MITE OVERRIDE 
Mute override in theory is a good idea IF you make it optional. Key word here is optional! With this new update I'm forced to have alerts go off in meetings and other situations where I switch my phone to vibrate. The only way around this is to open the app, switch your alert setting to vibrate, then remember to switch it back when you're done. Doesn't sound like a big deal, but trust me.. it gets old fast. Like I said. Make mute override an optional alert setting and everyone will be happy!
 
Bad update 
Needs more work.. The alert seems to go very loud.. Pls fix this mess..
 
The new update is horrible!! 
I've been using dexcom for such so long and it was always working perfect, I was able to check my blood sugars on my Apple Watch and be able to turn off the notifications when I'm in a meeting or class. But than..... dexcom updated their app and now it's the stupidest thing ever!!!! I can't look at my blood sugars in my watch and I can't even turn my blood notifications on silent when I'm in a important meeting or class! Dexcom, this was your dumbest thing you've ever done! Please change it back! Thanks
 
If it ain't broke don't fix it 
I kind of feel like I'm in the twilight zone with this update. I loved the app prior to this update but now I feel like my decisions have been taken away from me. Somehow someway the app finds a way to make noise even if I'm on vibrate only. I've even closed the app and it STILL makes noise. I'm terrified to even have my sensor on me in my college classes because it is dead silent and a little increasing buzz will surly get the attention of every person in the room. The constant notifications that I did not have before takes the decision away from the DIABETIC which is the last thing you ever want to do. Although I understand Dexcom is trying to cover themselves, do not make my decisions for me or I will be going elsewhere!
 
Make an option to turn off sound alerts 
This is absolutely unacceptable that sound alerts can't be turned off. Change this immediately or I will have to reconsider my using this product.
 
Update is incredibly disruptive!! 
Updated Review: The update brought some improvements but I can't recall them because I am so furious about the sounds. With the app notifications muted, phone sound off and settings reduced (limited options to adjust and not all can be turned off), I am still getting obnoxious tones. It's disruptive to everyone around me as well as myself. My sleep is cut into and people stare me down out and about. Furthermore, there's still no option to snooze alerts. They just keeping coming incessantly. I'm deleting the app and switching to the transmitter until this is fixed!! Previous Review: I am incredibly thankful for this app and Watch integration! I have had the best control over my sugar since having the G5 and this app in over 10 years! Having said that, few suggestions for improvement: Need ability to customize reminders. I do not need a reminder every 3-5 minutes on my readings or requests for input. Recommending an option to snooze for an hour, two or overnight. Would like to see glucose reading available on Watch face as we can with many integrated apps. Would like to see reports linked to glucose reading app instead of a separate app.
 
HATE IT 
The app was perfectly fine before it was updated. I despise this update. There is a reason for the vibrate button and "do not disturb" mode on the iPhone. There are certain times during the day where it's not acceptable for my phone to be making noise. Imaging sitting in class taking a test (in perfect silence) when your phone starts beeping relentlessly with increasing volume. It gets you some unwanted attention. PLEASE change it back to the way the older version was so that I can MAKE THE BEEPING STOP!!!
 
New update needs work 
I love the cgm that Dexcom gives. The accuracy is really great and the trending is something I would not want to manage my diabetes without. PLEASE bring back the user choice about audible alerts. Most users are aware that muted alerts increase the possibility of missing an alert. Most of us also realize there are times when a loud beeping from a device is completely inappropriate for whatever situation life has currently placed us in. As part of my job I have to inform family members of a loved one's death. Last week this sensitive situation was interrupted by 2 loud beeps that continued every few minutes as pulling out my phone and accessing the Dexcom app was inappropriate and rude. I can imagine all sorts of other situations where the alerts are equally inappropriate. Please let the user decide who should be aware of their current blood sugar and when beeping is appropriate.
 
Should have left iWatch alone 
Why in the world would you make an app slower when the one thing a diabetic needs is numbers and fast... old version worked so much better with iWatch than this update! New version is slow and takes so long my iWatch goes to sleep just like me while waiting for numbers! Completely defeats the purpose of having it for my iWatch! Fix the problem pleeeeeease! - concerned athlete
 
Very stable and helpful app 
Always been very stable and works great for me. I love not having to carry my receiver around and having my BG on my wrist. So convenient. The most recent update is even better! I like how it stays silent for the first alarm, but overrides for consecutive alarms. I must be in the minority, but the recent update works perfectly for me. If you set it up correctly, you can do two things: 1) Have all alerts only vibrate. 2) you can have it vibrate first and only make a noise if you don't respond. You have to dismiss the alert within the app. If everyone would just take a second to learn about the new app and the features that are meant to be an improvement, you would see that this app is very well designed and accommodates everyone (the people who like the old app and the people who want to audio override). All in all, thank you Dexcom! Very happy customer here with the recent update, please don't roll back! For those with issues, call customer support and they will help you better understand the features. The current (new) app can be silent all the time, you just need to adjust some settings and I'm sure they should be able to show you how. Not a Dexcom employee, just someone who works by the software industry and is willing to change to accommodate a diverse user base with different needs. Remember: this current update accommodates everyone (those who want silent and those who don't). You just need to work with Dexcom to understand the settings available to you and adjust yours.
 
Cannot allow to let themselves make this mistakes 
Overall the app does what's it's suppose to do but it has room for improvement and with this update Dexcom has taken a step back. For starters I see the good intensions behind leaving the alarms on despite what sound profile one might pick for one's phone but this doesn't work for everybody. I'm currently a student in college and if my phone is constantly going off because my glucose is high or low my professors will certain have a problem with that because that will not only be affecting me but everybody else in the class and that's just something that's not acceptable. Moreover, I do agree with most that the Apple Watch update has just made it less reliable because I have to keep on going back messing around with the crown to see any real graph trend because what's default is the 1hr trend which lack the information that I need to see when I'm just glancing at my risk to see how my glucose is doing in class. If Dexcom wants to improve and make this app platform useful for every user they need to give us the ability to adjust and implement the information that we as individual personally need. If I was able to pick and choose what information I want my Apple Watch to show constantly (6hr trend graph, 12hr or 24hr graph. Or perhaps thicker trend arrows since I have a hard time seeing the arrow) and I was able to set the sound profile that was most appropriate to my life style then everybody will be happy with the product that was released because we will be able to tune it to our specific needs and wants .
 
Worked Great Before Newest Update 
I loved my Dexcom app before the newest update! It was really cool to just look down and see my blood sugar on my phone instead of carrying one more thing with me. The problem I have now is the app is absolutely OBSESSED with my blood being a tiny bit high. If it's literally 180 it flips out and starts alarming me every few minutes. And the worst part is, if my phone is on silent, THE APP NOW TURNS ON THE SOUND ON MY PHONE. So during class I have to put my phone on Do Not Disturb or it goes off randomly. If my blood sugar is higher than 180, it maybe alerts me once, twice on a good day. But still turns the sound on my phone on. If it's low, it doesn't really alert me too much. So, other than these weird bugs, it's a great app!
 
Dexcom app should seek to improve quality of life 
First, I LOVE being able to continually monitor my blood glucose levels with Dexcom and I LOVE being able to do it on a mobile device and I LOVE being able to share my current levels. HOWEVER, the Dexcom app seems to be a decade behind on user experience design. The new update is constantly beeping at me for the dumbest things (example, being pinged every five minutes with a calibration request - at least dial down the frequency of the request). Is anyone with type 1 diabetes even involved in UX? The app should be designed with the goal of improving the quality of life first and regulations second. Both are necessary, but this app seems to be designed by regulations only (or at least first).
 
Noise alerts on silent in NOT okay and make a widget please!!!! 
Why am I no longer in control of this app?? I am a college student and I need to have my phone on silent when I'm in class. I have already had my phone go off in class which was disturbing to my peers and embarrassing for me. And I can't even fix it by turning the volume down because the app just turns it up. That's not okay Dexcom. Don't force people into this change, make it an option. 2) The thing I want most from this app is a widget so I don't have to open it to see my blood sugars every time. 3)The ringtone choices are terrible. Please get some new ones that are normal, like the iPhone ones, none of this baby crying or fire tuck stuff.
 
Update is laughably bad 
What, you think I can't read my phone so you make an update to override my silent and do not disturb? Get over yourself, dexcom. I've called tech support and there's a literal list of people complaining about this. Fix it or lose business.
 
MAJOR SAFETY PROBLEM WITH UPGRADE 
The latest upgrade has a major problem. The only way to silence the low alarm is to completely quit the app. So if say you're at a concert or church and they remind you to silence your devices YOU CANNOT SILENCE THE DEXCOM! even if you've taken a bunch of sugar tabs. So you have to quit the app and have no info about your glucose! This is a major safety issue that ruins the beauty of the Dexcom.
 
Apple Watch Poorly Designed 
The Apple watch 'complication' or face is poorly executed. Rather than settinge the Dexcom icon on my watch face, I want to see my current blood sugar and where I'm trending. That's what needs to be there. There is a third party app called WatchSugar which although not great does have the functionality that should've been included N the new update. Currently accessing the Apple watch app is made easier with this new update, but I want to see the data I need without an extra click... Hope this gets updated soon.
 
Wish I could give negative stars 
Nothing says useful like an alarm you can't silence when its giving an urgent low, but the calibration is off. It's even better when you're in a situation where silencing the alert and waiting for the cgm to catch up would have been fine. I use the cgm to help control my diabetes not let everyone within hearing distance know I'm wearing a cgm.
 
Alert Bugs in Ver 1.5.1 
Ver 1.2.4, the previous version was much better in regards to alerts. Please know I’m on iOS 10.1.1 and Watch OS 3.1 and an iPhone 7 Plus and an Apple Watch Series 1. The oddest bug circulates around my iPhone and my Apple Watch. In Ver 1.2.4 if my phone was not being used and an alert pinged me it only went to my watch or if I was on my phone it would ping my phone and not my watch. From my understanding that is the normal way alerts should work with an Apple Watch and an iPhone. However, in Ver 1.5.1 I was using my messages app and a low blood sugar occurred, It pinged my watch and my phone at the sametime and on my phone as the alert event went off it progressively got louder in about 3 seconds time and as it did that the volume controls appeared on the screen showing my phone going up in volume. Other bugs have happen where the alerts works perfectly normal and if I don’t clear an alert it changes from going from my watch only to my phone only and it also has gone to both my phone and watch as well at the sametime. It is also random on the volume level. It has pinged my watch and phone on the first sign of an event alert and the volume is pushed to the highest volume setting and when I checked my phone the volume is only 4 clicks up from the lowest level. The alerts are very buggy and VERY inconsistent on how they react and notify me when my Apple watch is on my wrist. The app was 4-5 stars until this started happening. If you need any more information please free free to ping me back. Thanks again, Jason.
 
Overall app is great - updates not so much 
I am not a fan of the new update to bypass phone settings and still play alerts. It's great for some but I think this feature should be an option we turn on. I like the old version better, aside from the added vibrate alert. I get a few false urgent low readings every week. Dexcom hasn't been able to help me resolve this but I've adapted to it; however, having to hear the alert and now all these other alerts is forcing me to just close the app for the majority of the day. It may not make sense for me to continue using Dexcom if I can't control the sounds, I'm sad to say. Hopefully the update soon.
 
HATE THE UPGRADE 
Can't silence the alerts before I go to meetings. Can't silence alerts at night. App freezes every time you get an alert. You get multiple unsilenceable alerts for each event. What idiot thought this would be an improvement.
 
Don't mess with a good thing 
I hate the new app. No matter what I set it on or even if my phone is on silent, I'm getting loud alerts. If I wanted this option I would turn the sound on on my phone. I have my phone on me constantly and it's distracting to have it going off with noise while at work. Everyone seems to be in agreement. Fix it please.
 
Terrible 
I'm a 54 year old adult physician with T1D. I do not need Dexcom to decide FOR me that I am not allowed to silence their app!!! Are you kidding me? You can imagine the DISRESPECTFUL interruptions by ME and your ridiculous app during delicate patient interactions. It worked fine before and this update is terrible . I just had to delete the app so I can see patients without its repeated HONKING.
 
Sounds settings are terrible 
I loved this up until the latest update where it turns your sound on even if you are in vibrate. Therefore if I go low I have to close the app to avoid the loud alerts which is exactly the opposite of what this app is supposed to be for. Please change this back to the way it was
 
Bad update 
Was happy with the app until the newest update. I purchased the Apple Watch so I could receive discreet alerts without having to pull out my phone. Sound changes in the new update now require that I have sound alerts turned on (sounds that over ride the mute setting btw) in order to receive "haptic" alerts on my watch. The Vibrate Only setting turns off the watch's haptic alert. Pretty much defeats the purpose of discreet alerts. I also dislike the required sound settings for Urgent Low Alert. Given the lag time of the Dexcom sensor, my blood sugar is often on the way back up and my Dexcom is still giving me Urgent Alerts. Requiring them to have sound just adds insult to injury.
 
Fix not being able to silence alerts 
What's wrong with you people, give people the option to silence or turn off the alarms gave to Dexcom receiver if people want to use that let use that if they do not want to be able to turn off the alarms.You are taking over The control of my iPhone thats not good.use vibration only for the urgent Lows.
 
Give me back control 
How did Apple approve an app that overrides the mute button? To have audible alerts or not is MY choice, not Dexcom's!!!
 
Works well; Needs more alert options 
I like the app and love the sensor. However, only 3 stars due to limited alert options. Each alert can be set to off, vibrate, or audible. If audible is selected, the alert remains audible even when the phone (iPhone 6) is switched to silent. The alerts should have an option to turn off the alerts sounds when the phone is in silent mode. (Either a single alert setting or a setting on each alert.) When I'm someplace that I need my phone to be silent, I want alerts silent. For me, if my phone is set to silent, vibrate is satisfactory. If my phone isn't set to silent, I want audible alerts.
 
Freedom to silence 
Dexcom G5 is the best CGM I have ever used. The accuracy is superb and I rely on the readings heavily. It's disappointing to have to give a two star rating but after the recent update that makes it impossible to silence audible alerts I haven't been able to take my phone to meetings. I'm well aware when I am trending low and I preferred to correct silently without having an audible alert go off. As an Apple Watch user could we change the setting to just have haptic feedback? Not everything needs to beep!
 
Embarrassing and unprofessional 
I'm very frustrated with this new update's alarm features. I have always kept my phone on low or silent because I work in health care and because I generally don't like beeping and alarms. I've already been embarrassed by my dex going off in a clinical area where phones are not allowed (I only keep it for the Dexcom visual feature) and I anticipate this being a problem in the future at my work. Some of us need that silent and do not disturb feature to STILL FUNCTION AS THAT. Please change the options so that you can choose to have alarms come in, and if they do come in over the silent feature you can decide what volume they sound at. The fact that my phone goes from vibrate to AS LOUD AS POSSIBLE if not immediately acknowledged is unacceptable to me and has embarrassed me. Please please please bring back the old option. I understand that some people want this feature so can we have the option to choose? Please?
 
Dangerous 
This is a dangerous update. By removing the option to silence an alarm as you'd silence your phone, it makes this app unusable by people like me (I will lose my job if I have an alarm interrupt production). Combine this with the fact that it no longer works with my Apple Watch, and I'm back to finger sticks 3 times a day.
 
Fix Fix Fix 
The new update is not worth it. They removed the silent and vibrate options for low alerts. This needs to be fixed. I don’t want my phone providing audible alerts during meetings, at the movies, or whenever I put my phone on silent. If not fixed, then I guess I’ll have to stop carrying my phone around or just remove the Dexcom sensor. This update makes me want to remove this thing.
 
Awful 
This new update is awful. I cannot mute the alerts and it's hard to go to class when sounds are constantly going off. Fix this I want to go back to the old version
 
Blood glucose 5⭐️ alerts 0⭐️ 
This app is amazing at displaying blood glucose and trend. It is the most helpful thing in my diabetes care. The new update and alerts is horrible not to be able to mute. Plus you can't change the urgent low glucose threshold. My tolerance is a bit lower than that. The sounds you have to pick from are all incredibly annoying. For me, wearing a dexcom is a choice, so should being able to turn off the audible alarms. Vibrate always works well enough for me. Perhaps it is an FDA thing?
 
What a setback. Bring back the prior version!! 
Until this update, the app worked great. However, now it keeps crashing when i try to launch it from my iWatch. I loved to be able to check my sugar inconspicuously on my watch without pulling out my phone, but no longer… Can you please post the prior version??
 
This app might be worse than diabetes itself 
Listen. I understand that some people want to be able to hear alerts NO MATTER WHAT, and that is fine. But I am not one of those people and this needs to be an optional feature. My phone has been vibrating constantly for a week since this dumb update came out. It's driving me insane and making me seriously consider not wearing the dexcom at all. Fix it. Now.
 
needs work 
I know people are going to say i'm an idiot and that i don't understand when i say this but there needs to be a way to mute all alerts or at least put them on vibrate. For people who say I don't know what diabetes is like I was diagnosed when i was 2 with type 1. So Yeah, I do know what it's like. I am constantly checking my phone for alerts but it is a real hassle when i can't turn off my notifications when i need them to be off or face possible repercussions. I believe there should be an optional way to mute alerts. It would make sense. And if anyone dares to argue with me that i don't know what i'm talking about, i cannot remember a time when i didn't have Type 1. There NEEDS to be a way to mute alerts. Also you'd think the makers of this app would get smart and realize that they're rating dropped to 1.5 stars because people HATE this new update. Just saying
 
Recent update notifies way too often 
31 year T1 here. Use a G5 with an apple watch and iphone 7. First, I love the dexcom product suite and use it witb my T1 daughter as well. Thanks for the great work. Second, this release gives way too many notifications with no ability to adjust frequency (alert repeat can be adjusted, but if you dont acknowledge the alert it repeats every 5 minutes). Do i really need to be reminded every 5 minutes to calibrate? Ux really suffers here wildly. Give some control to the user, please. As for the watchos app, whats the point of having an app on my watch if i can't acknowledge the alerts? Major watch app fail. That said i like the scroll functionality, but would really love to see the developers give some idea of the difference from last reading to the current one.
 
I can't stop the alarms!!! 
I looked at the reviews here because I suddenly couldn't stop the alarm noises!!! I'm not alone in being angry! Mute won't stop the noise, do not disturb won't stop the noise, the only way to stop the noise is to close the app, which I now do at night. The FDA should take not that many people need to close their Dexcom app in for confidentiality reasons and in order to sleep. Also, I can't set the notification alerts to less than 15 minutes. There are options for 5 & 10 minutes, but it always rolls back to 15 minutes. Bizarre!!
 
Must have an option to turn off the sound! 
Audible alerts are great when you want them and absolutely horrendous when you don't. Nothing else to say. Please update to allow for silent mode.
 
Not to sure why everyone is complaining 
I overall like this app. But, it needs some features to be my sole diabetes app. Which I want it so much to be. Need to have active insulin information, a insulin dose calculator and Notes Notes Notes. Come on I know you can write notes with a pen 4 months later at my dr appt, but will I really remember anything. I have a phone let me type. I haven't had to many problems. I know a lot of people are complaning about the Sound features, but I think given this is a medical APP you would expect this type of override. Two ways to fix it, fist control your sugars better or put it in airplane mode when needed. But, if it's on I would expect the sound to be on. Only thing I would like to see is a better overall user interface/design. It is not bad at all, but not as cool as it could be and a little generic.
 
Dexcom good/bad 
Used dexcom sensors for a while, love them. Refuse to use any other sensors. Have used dexcom for a number of years and the app for the last year. Traveled around the world with it. Biked and hiked through Asia in the rain. Fought off wild monkeys that tried to steal the transmitter on islands in the south Chinese sea.... awesome awesome awesome app.... UNTILL THE UPDATE!!!!!!! Unfortunately it has some MAJOR flaws. For example whenever an IOS update comes out, the app goes bonkers and restarts its self all the time. In the last week for example-- I have checked the app to monitor my blood sugar and without any warning it has ended (and I'm in the middle of some commitment that goes on for hours).... Noise settings on it are terrible.... you can't silence it... and then when you need it to be loud (like wake you up at night) it doesn't really do anything.... alarm system is terribly thought through
 
Sound off 
The new update is terrible! The only way to turn off the alerts is to shut down the app in Notification Center. I'm in meetings everyday and I can't get the app to be quite when I need it to be quiet; even when my phone is set to vibrate it turns my volume up and still beeps! Dexcom please fix this issue!
 
Life changing - NEED SILENT NOTIFICATIONS 
Update: -4 stars for removing silent notifications :( don't want vibration, don't want sound - just a notification to my watch. Why isn't this allowed anymore?? Really like the more flexible plot on the watch app. Wish list for the watch app: - be able to enter BG results - view current BG in the complication icon (just like weather), with trend icon if possible ------------------- Great app, does its job wonderfully. This app plus the G5 have made a huge impact on my daily diabetes management. Love the new widget! Only wish is being able to pinch zoom in/out and pan the graph in the app when the phone is set to landscape mode, and be able to write in my own words what food I had when adding a Carbs event (in addition to the carbs value). EDIT: Love the Apple Watch support!! How about being able to enter BG values through the watch?
 
Bring back last version 
For those of you who are now using the latest G5 update you have noticed some nice improvements. However, the decision to override the Mute and Do Not Disturb functions of the iPhone is very worrisome. They have essentially taken something away from us, instead of given us something useful. Now, we are awoken on many nights for every single alert and alarm on our G5. Do I need to be awoken at 3am to calibrate? Is that an emergency? Or at 4am that my sensor is going to expire? Really? Dexcom, can you give us on option to turn this new 'feature' OFF. I was very happy the way it was before. And for those who like this feature they can turn it ON. The Do Not Disturb function is a VERY powerful feature of the iPhone, and Dexcom has taken that away from us without our consent. Please fix this is and give us our options back.
 
Does not obey notification sound settings 
Delivers repeated audible alerts that cannot be disabled or dismissed reliably. Fine app otherwise, this makes it probably unusable if you know, have a job or something
 
Awesome, but a couple huge flaws 
I had to lower my star rating. The app shuts down ever other night around 1am. This is due to a "system memory reset". Dexcom says the only solutions are to either reboot my device everyday, or to use the Dexcom receiver as a back up. The change sensor alert is still fixed at 6 hours and there are no options to change this. Anyone who puts a new sensor on in the morning will be guaranteed to be woken at 2am the following week. You can't see trends unless you switch to landscape mode. Then, if you do, you can't see your current number. Many people keep their screens locked to prevent rotation. Make the trend and number visible in both views please.
 
Great but.. 
This app works great over night, but throughout the day, when I'm opening apps and using other things on my phone, it tends to lose signal, even when I have my device in my hand. My graph is very spotty throughout the day, and I would like that to be improved.
 
Completely Unrelisble 
This should be a great app, and if it worked reliably I'd give it 5 stars. But almost every night and occasionally during the day it loses the signal - for no apparent reason. Reported the problem months ago: no fix.
 
Pretty good 
I had to delete the app and reinstall it in order for it to work properly, but so far so good. I've used this in the past for my iPhone 5s and had no problems so hopefully it will be the same for this new phone now that I have it reinstalled. Hopefully I won't have any more issues.
 
User unfriendly ! 
Documentation on how to install the Dexcom G5 on another iPhone! Not clear on how "share" comes into play!😡
 
Works well, some times 
Great App when it is working, but I get a "signal loss" screen about every two days and the only way to get it working again is to delete the App (which removes all memory), download it again, and then perform the arduous task of setting it up. The memory is the most important thing about this App, because it lets me record overnight levels. If that is important to you, use Tidepool.org (a free service) as a backup.
 
Amazing 
I love that my blood sugar can go strait to my Iphone. It makes it so much easier beacuse you only have to carry aroud one device. Can’t wait until you can boulus off the app!
 
It's COMPLICATED 
Dexcom. Either you or Apple is teasing me with that Dexcom complication that was shown on the watch face during the WatchOS 3 keynote in June. I need that in my life. This app is now excellent. Many users have asked and begged for a native Apple Watch interface like the G4 had as well as a Notification Center widget. Both have been implemented and delivered to perfection. Thank you! Original review prior to update: "All I want for Christmas is a native Apple Watch app. 🎅🏼"
 
Lifesaver 
I love this app because it can send low notifications to friends/family. I live alone and this feature has helped me out more than once.
 
Decent App Could Be Better 
Having your Dexcom CGM paired with your phone is very convenient. The app is adequate in its function, however there are some features I'd really love to see implemented. 1) A night-time mode that inverts the colors or uses a less bright interface would keep the app from blinding me in the middle of the night. The widget update, which I love, is decent, but if I need to open the app to calibrate, it'd be nice to have. It would also help in dimly lit environments where I'd prefer to be more discreet when using my phone. 2) The ability to swipe/scroll backwards through the timeline in vertical orientation without needing to flip my phone sideways. It seems like a very intuitive feature and would make using the app more efficient. Also an ability to scroll over past readings in vertical mode to get the exact number, which is now only possible in horizontal mode. 3) When flipped horizontally, it'd be nice to pinch zoom the timeline to focus in on an area. 4) Lastly, visualize calibration points on the timeline. I imagine this can be done by making the calibration points on the timeline red as to give you an indicator of your last calibration without needing to scroll through the menu. Overall, I'm glad this app exists. I look forward to its continued improvement.
 
Shutting off all the time!! 
Since The new update it has been spontaneously shutting off ALL THE TIME. This is a huge problem!!!!!
 
Great App - Hope for more updates 
Great App! Just two comments: - Visualization could really use an overhaul. - It would be very helpful to see BG in the notifications. Therefore if I'm high or low, I can just peek at the phone without pulling it out to see my reading.
 
Was great before 
After the update to work with iOS 10 the app I once loved has turned into a nightmare. My doctor wants to know my highs, lows and trend patterns. Now I find my Dexcom telling me my blood sugar is 140 give or take. Doesn't feel right. Test with a meter and it tells me 68-80. Try putting that into my iPhone and it tells me to wait until a certain time. Totally unacceptable. Developers need to go back to the drawing board. If this keeps up, will be going with MiniMed integrated CGM with my pump.
 
Great base but a few suggestions: 
Have been using Dexcom CGM's for 3 years now. Love them and the G5 is by far the most convenient. I am also an Apple Watch user and use the app on there as well. Some suggestions from a fellow UI/UX designer and Software Engineer: 1) Enter blood glucose reading notification doesn't need to be something that repeats every 5 minutes. Not a big issue if you have a phone, but if you use the watch, it will keep going continually until I open the app. This is a hassle when I am sleeping with the watch on (which I do specifically to make sure I receive other Dexcom notifications). 2) The ability to clear a notification from the Apple Watch. What I mean is if I get a high BG notification on my watch, I should be able to let the app know that I have read that without needing to grab my phone. 3) A customizable setting that allows me to set a duration for when reminders should restart. By this I mean that if I do clear a high BG notification, and I stay high for something like 2 hours, it should start notifying me again that I have yet to go down back into the normal range. Hopefully this setting can come with a few options for a duration to wait before starting reminders again.
 
Where is the new update?!?!?!? 
This was a great app. Worked well with my Apple Watch and now I can't pair my new transmitter to the app. So now it's back to the old Dexcom receiver. Seriously let down by there not being any update, especially since this is an app that syncs with a medical device. So either avoid updating to ios10 or don't waste your time.
 
Bluetooth issues 
I've used this app a couple of months and have high expectations for it. But currently the Bluetooth is totally unreliable. It drops connection constantly then states it can't find the device. I would have returned the Dexcom if not for the handheld receiver which is very reliable.
 
Love yet need more customization 
I am incredibly thankful for this app and Watch integration! I have had the best control over my sugar since having the G5 and this app in over 10 years! Having said that, few suggestions for improvement: Need ability to customize reminders. I do not need a reminder every 3-5 minutes on my readings or requests for input. Recommending an option to snooze for an hour, two or overnight. Would like to see glucose reading available on Watch face as we can with many integrated apps. Would like to see reports linked to glucose reading app instead of a separate app.
 
Poorly done 
You can log things like carbs and insulin - but i cant seem to find a way to see what was entered. (Being able to overlay this with BG data would be even better!) How they show the graphs are just stupid. All the data is squeezed into a tiny bit of an otherwise empty screen. No ability to auto scale or even pinch-zoom. They really look at how something like drip+ - or any other kind if data visualization software works. I also had a crash problem in initial setup that require me to remove and reinstall.
 
Dexcom good/bad 
Used dexcom sensors for a while, love them. Refuse to use any other sensors. That being said, the app is an incredible idea and it has been wonderful! Have used dexcom for a number of years and the app for the last year. Traveled around the world with it. Biked and hiked through Asia in the rain. Fought off wild monkeys that tried to steal the transmitter on islands in the south Chinese sea.... awesome awesome awesome app. Unfortunately it has some flaws. For example whenever an IOS update comes out, the app goes bonkers and restarts its self all the time. In the last week for example-- I have checked the app to see my blood sugar and without any warning it has ended the session and says I need to restart it.... this is just slightly annoying as some times you are really counting on the app to work. Working in a sterile bio lab or being on a date and suddenly having to run around and find the glucometer you hardly ever use since you have a sensor.... Still... app is awesome... wish it was a bit more reliable and was a bit friendly with looking at trends and times.
 
Was good 
Before iOS10 the app was great but since I updated the app it crashes half way through syncing the Dexcom device. Only good currently if not using iOS10
 
LifeSaver 
I was diagnosed with T1D the end of last year and this has been a lifesaver for me ever sense but the bug is the mute if you're volume is all the way down it will say the app is muted but alarms will still go off out loud so to mute the alarms you have to use the switch on the phone.
 
Great app 
I love the app, so handy. Lately it's been telling me signal loss even though I'm 8 inches from my phone. Hopefully they get this fixed. Quite annoying to have my phone go off every 2 minutes
 
Huge problems with the new iOS/app update 
I have had nothing but problems with the new update. Warnings not going off. Updated control sugar levels not taking causing repeated testing. App crashes for no reason while running in the background and not warning me for an hour. Wow let do some research please and not use people as guinea pigs.
 
Quit killing playing music when opening G5 app 
Quit killing music that is playing when you open G5 app.
 
IOS 10 ALERT PROBLEM 
Several times I noted that the little ringer icon with the slash through it indicating that phone was silenced but it wasn't. Today I missed a low alert because the app did not sound the alarm. I saw the icon appear & disappear when I opened the app.
 
Great!!! Only reason I switched back to iPhone! 
Am really happy with being back on iPhone , but wow this app is so great. Obviously will love any updates etc. But this is fantastic.
 
Game changing CGM 
not much to add other than what most have already said here. 24 year T1 diabetic and this has made my life so much easier! Suggested improvements for iOS app: •provide BG in notification alert •allow scrolling and viewing of trends within portrait view •allow more than 24hr trend view (48,72, 1 week?) •not sure if it's Health/apple app issue but allow real time Health app view instead of 3 hour delay. Apple Watch •useful complication w/trend arrow and BG value •option to scroll trend directly on Apple Watch app Thank you for your hard work here!
 
Great improvement over receiver. 
Reviews seem to be harsh. I've had no problems with compatibility and iOS 10. However I did update before downloading the app. Not having to carry a separate receiver is great! One small recommendation I would like to see is ability to tweak colors on the graph. Setting up the app and linking to the transmitter was a breeze. I like it!!
 
Life changing 
Great app, does its job wonderfully. This app plus the G5 have made a huge impact on my daily diabetes management. Love the new widget! Only wish is being able to pinch zoom in/out and pan the graph in the app when the phone is set to landscape mode, and be able to write in my own words what food I had when adding a Carbs event (in addition to the carbs value). EDIT: Love the Apple Watch support!! How about being able to enter BG values through the watch?
 
Force closes all the time ios10 iPhone 6 
Force closes all the time ios10 iPhone 6
 
Needs update 
Keep getting signal loss after new iOS software update
 
Locks up with iOS 10 when left in foreground too long 
Program locks up on iOS 10 with no warning every couple of hours when left in foreground (with screen lock set to never.) Stops monitoring and reporting blood sugar. Very dangerous! Please fix! Was great on iOS 9. I use it for my daughter who is 4 on iPhone SE, with it continuously open to the app main screen. It eventually locks up but holds the last reading indefinitely appearing to be working if you don't look closely. Temporary workaround has been using the widget screen and leaving app in background where it seems to reside without issue. Hoping for a fix soon.
 
STOP BUZZING IF I ALREADY CLICKED OK 
Lows and highs take time to correct. If I see the alert, then swipe to unlock, then launch the app, then click "ok," chances are I got the freaking message. Stop bugging me. Also, still an amazing system. But with the above glitch it's like marrying the person of your dreams then moving in with the obnoxious stepmother the rest of your life.
 
After iOS 10 
It doesn't work.... if someone could fix this that would be awesome because my 8yr old really needs this to work
 
Apple Watch functions 
I love that the App. I wish I could acknowledge the high or low readings from the watch notifications without having to open. I would like to the current reading show as a constant like the weather icon does. That would be an awesome feature. All I would have to do is look down at my watch. 😊
 
ios10 is a disaster 
Dexcom does not function on ios10 with any form of consistency. 1) the app crashes constantly, especially after starting any other app that uses Bluetooth 2) numerous near medical emergencies because the app crashed and I had no idea until I woke up in a deep sweat near seizure in the middle of the night 3) says on silent when it is not 4) app randomly turns a dark faded color and responds to no commands. Forced to kill app. 5) having to restart phone multiple times a day to keep app even working. 6) constant loss of signal. Changed transmitters, reinstalled app, constantly loses signal. Tried switching to my backup iPhone and no issues. Definitely ios10 related. Dexcom should issue an emergency declaration to all users to not use ios10 if you want any sense of safety. It's been weeks now and no update despite every app I have installed with numerous updates since ios10 release.
 
Great app but have a suggestion 
I just upgraded from the G4 to the G5 and love the iPhone app. One suggestion to make it better: set up the app icon to show us the BG # right on the icon so I don't even need to open the app. Similar to how the calendar app shows us the date without opening it.
 
G5 a downgrade from G4 
The dexcom technology is great, but G5 should have been way more mature before being released. If there's one thing I've learned working in product engineering, it's that you never take away a feature you had previously offered when "upgrading" versions. Compared to the G4 app, G5 is harder and takes longer to use. I should be able to see how long ago my last reading was taken (share showed 1-5min) and I should be able to change the x-axis of the graph without having to turn my phone to landscape mode (which you could also do in share). Get with the program, software engineers.
 
Only thing missing is the complication 
The phone app is simple and easy to use. The watch glance works, though it does like to drop connection to the phone. If it does not come back on an hour, usually end up removing and reinstalling app on the phone. This needs fixed. The biggest draw back is the watch 'complication'. All it does is show a link to the phone app. Worthless. What I need to see in 2 seconds is the number. Not a link. Direction of change would be nice is optional and only if there's room For more detail, I'll pull out my phone. It's in there, just show it.
 
The lag 
While it's an awesome app it still lags it was telling me I was low when I was at 155. My parents are crazy stressed cuz their phones don't get my blood sugars cuz it reads NO data can you guys fix the lag please. It's stressful
 
Flawed. 
Really needs a vibrate option for the alerts. They said whatever your phone is set to will override the settings of the software on the phone- even when my phone is on vibrate the alarms within the app don't notify me. The accuracy IS SO MUCH WORSE then the G4. The app CONSTANTLY re-alerts me for the same low or high BS. I have both 'repeat' options set to 'never'. It's suppose to only repeat alert if you are below 55 but it has consistently mouth functioned since I updated to the G5. Customer service is usually nice but they can't help solve the issues. They had me delete the app and reinstall it 4x and it's still doing the same thing. The flaws are super annoying and the accuracy makes me want to go back to the G4. I would wear a receiver on my side knowing its close to an accurate reading then see a false blood sugar on my phone. ^^^ I wrote that about two months ago and have been on the G4 system since. I actually just cancelled all future orders from Dexcom, I'm done with the company altogether. They have sent me at least nine replacement receivers since August and every single one has the same issue. It alerts me over and over for the same blood sugars. I've been alerted six times in the past 45 minutes until finally I turned it off and took the sensor out. The repeat for a high blood sugar is set to 300 minutes so there's no chance it's not an issue with the receiver. I gave up on the company. The G5 system was poorly executed and since I've received nine receivers with the same problem, I have no faith in the product(s) or company. Customer support is terrible at this point and I imagine it's because of how high the tech support phone call volume is. I love my a1c being at 5.8 but I would rather check my finger 15 times a day then deal with this crap. I will never use this company again, ever.
 
Nice attempt 
The complication for this app is useless, new quick glance is very basic. Let's see if Bluetooth is fixed
 
apple watch support is awesome! 
I agree with other reviewers that the iPhone notification takes up too much real estate. Just the value and the direction arrow would be enough here; the graph is not needed here. I agree that the Apple Watch Complication should be the value and the direction arrow. Here is a suggestion to Apple Watch users: Open the Apple Watch app on your iPhone. Go to General >Wake Screen and under On Wrist Raise select Resume Last Activity. That way if you open the Dexcom watch app, it will show the Dexcom app up every time you raise your wrist to look at your watch. And it does show the time! I wish the time were in a larger font.
 
mmol/L 
I would like to be able to switch between mg/dL and mmol/L.
 
Shortcut is an improvement 
Shortcut is an improvement. However is there a way to present the glucose values inside the app similar to the date on iPhone calendar app? Takes too much effort to swipe down or open app regularly. Look forward to additional enhancements. Thank you.
 
Good, but needs little tweaks 
I would like to see an option to view a timer for how much time is left on the sensor. Not just pop up warnings.
 
Great App! One suggestion... 
ALL I WANT is to be able to "acknowledge" alerts from the Apple Watch. Just like you have to "acknowledge" highs and lows by physically opening the app on the iPhone, when I get alerted on my watch, there should be an "Ok" option to cease the 5-minute alerts. This would be so convenient and it's all I ask for. Thanks!
 
Love it! 
Started with animas pump that worked with dex G4. Recently upgraded to G5 in hopes it would be compatible with Apple Watch. Watching reviews and saw they added Apple Watch and was thrilled. Next day purchased Apple Watch. Can't believe I'm viewing live bg on my wrist, thank you so much for making it so much more convenient to monitor. Love the way it is now, use last viewed screen on wrist raise as others have suggested and it's worked flawlessly. After all I bought the watch for this one function. I like the 3 hour graph too. I can understand how others would like a live complication but I can't complain. Only suggestion I have is to allow you to dismiss alerts from the watch and edit alert tones. Thanks so much I appreciate all the progress!!!!
 
Needs an update or something 
Was working just fine until today it stopped and said incompatible iOS so maybe they should keep it useable
 
Love it 
I love my Dexcom and that I am able to view my glucose on my phone any time I want. I would really like to be able to see my daily graph in a 3hr, 6hr, 12hr, and 24hr options, like the Dexcom follow app has. I don't feel like that would be too difficult to add! :)
 
Constantly looses signal 
It was working great, but with this update it loses signal even when the phone is right next to the sensor.
 
Great App with room to grow 
This is a great app so far and I have found it works great for my use with iPhone. I'm glad to see I can quickly glance on the Today screen instead of having to open the app every time. I also enjoy the Apple Health integration. I would like to see this area improve more. For those that enter Carbs, Insulin, Exercise, etc, I would like to see further sharing of this information with Apple Health. Still a great app in my review!
 
Can be better Bluetooth 
love this dexcom it helps a lot but it's also off of my blood sugar a lot and some times disconnects really easy so if you have a child who likes to play on their phone and has dexcom it will disconnect a lot
 
Terrible. 
Literally all it does is ping my phone constantly to tell me that the connection "Is lost", despite my transmitter being less than 3" from my iPhone. Never shows a blood sugar ever.
 
Good not great 
Would be nice if there were more analytics. Averages by day/time etc. Correlation between BG and insulin usage would be nice too. There's some really valuable data that is loaded and it isn't hardly used for anything to put it to good use. I'd even like to be able to just export all the data in a spreadsheet too and do analysis myself. The app is useful and reliable but leaves a lot to be desired.
 
One major improvement needed 
To get more than two stars from me they need to add a timer that shows how much time remains before the initial two test calibration is needed (a two hour countdown) and the time the next calibration is required
 
Can't live without it! 
This is the best app ever for a type 1. I feel so great knowing my blood sugars at all times, and the alarms keep me safe at night/driving/at work etc. The convenience of having it on the phone really helps!!!
 
COULD BE BETTER 
Great update, however, there's a handful of things that could be improved. #1 The new complication feature for the Apple Watch is simply a shortcut to the app. This is useless! We want to see our glucose number here! The idea is that we can simply look at our watch face and see our number/trend arrow, without opening the app. #2 I would also like to see more functionality applied to the watch. For example, It would be great if we were able to enter meter calibrations as well as Carb and Insulin doses right from the wrist! You can make it so it uses the watches Digital Crown to make entering super quick & easy! #3 As for the iPhone, we would really like to be able to simply pinch & scroll through our day on the glucose graph. This would make it much easier to follow our daily glucose levels in greater detail. On that note, to help make viewing even easier, I would also like to see the option of having a continuous line on the graph, as opposed to just getting a bunch of dots. It would also be great if there was a dark mode that could enabled. This would be especially helpful at night, so we don't blind ourselves! I think you guys are on the right track. I hope to see these and other changes in the next update, as it will make for a more practical experience for us diabetics.
 
Signal loss + No Support for iPhone 6 
The iPhone 7 is around the corner and your app still doesn't support the resolution of the iPhone 6? Come on guys. I'm also getting a lot of no data readings on the app despite my receiver getting them just fine.
 
Transmitter issues yay 
Installed a new transmitter less than a week ago, and today the app has decided not to recognize it. I snapped the picture of the box, and it started to act like it was going to recognize it/sync and then changed its mind and stopped recognizing it again. Going to use the actual Dexcom reader thingy to try and troubleshoot but I am really not happy right now.
 
Excellent (revised) 
This app is now excellent. Many users have asked and begged for a native Apple Watch interface like the G4 had as well as a Notification Center widget. Both have been implemented and delivered to perfection. Thank you! Original review prior to update: "All I want for Christmas is a native Apple Watch app. 🎅🏼"
 
Needs support for higher resolution screens on iPhone 6/6s 
I love the system, but the app really needs support for the higher resolution screens on the iPhone 6/6 plus and iPhone 6s/6s plus. It's been almost two years since the iPhone 6 was released and almost all apps have been updated for the bigger screens. Right now the app looks blown up, fuzzy and old. It could also use some more features like 3-D touch support. I can think of so many ways that would be useful for. Over all, the app looks very old and it really needs to be updated to take advantage of new useful features.
 
Great but constantly disconnects 
It's great when it's working but the app constantly disconnects from my sensor. The receiver is far less prone to disconnecting. Could you also add the ability to add a text note (much like I can annotate when I put on insulin). This can help me keep track of insulin site locations and their effectiveness. Notes for other activities that = sugar level. Food factors, sleep... Etc.
 
Need to format for iPhone 6 
Seems to work good but it's been 2 years since the release of the iPhone 6 and it still isn't formatted for that. Ridiculous.
 
Great Start - Need some Enhancements 
I got the Apple Watch just for this option. I would like to see the current number with arrow indicator instead of an app symbol on the face....eliminate the need to open app to see current level/trend. Otherwise what a simply terrific app and makes my life easier dealing with hypoglycemic unawareness.
 
In the right direction 
When this app was first released, it was very bare-bones. You could view blood sugars, but you had to use a workaround to get the items to appear on the Apple Watch. Now that the app has updated to offer Watch functionality, let's get that reading in the Complication! It's as easy to swipe up on the watch face to view the graph as it is to tap the Complication, so please put that functionality of the Complication to better use! It would also be great if the app could be used independently of the iPhone, as the watch is able to connect to WiFi directly, and be paired to Bluetooth items.
 
Not compatible with current iOS. Unstable. 
App crashed during configuration. I've been a DexCom user for 4 years and jumped at the chance to just use my cell phone and get the receiver out of my pocket. Extremely disappointed that the app is currently not working.
 
Game changing CGM 
not much to add other than what lost have already said here. 23 year T1 diabetic and this has made my life so much easier! Suggested improvements for iOS app: •provide BG in notification alert •allow scrolling and viewing of trends within portrait view •allow more than 24hr trend view (48,72, 1 week?) •not sure if it's Health/apple app issue but allow real time Health app view instead of 3 hour delay. Thank you your hard work here!
 
Dexcom is great but I'm having problems 
Usually good but I'm getting tired of little problems like how when I don't go on the app for a while it stops recording data and now the app doesn't even work it crashes over and over so I tried to delete the app and reinstall it but now it's saying I can't login because the servers are down.
 
Changes CGM Monitoring 
This has been a great addition and the Apple Watch support works very well. This paired with the share app is a dream come true.
 
Imperfect but still BEST THING ON THE MARKET 
Why so many haters? Maybe they're omni users bummed about not having an omni app.
 
Awful 
New update doesn't work and won't allow me to even pair the device despite many attempts. It continues to state that the server is down. This has been for multiple weeks. It is just useless.
 
Keeps crashing 
After updating to latest iOS version my dexcom app crashes. Several times throughout the day. What's scary is when it happens at night time and you have a low blood sugar. This needs to be fixed asap. Better app testing needs to happen with new iOS versions. App also gets stuck when high/low blood sugar notice appears.
 
Frustrating because what's possible is visible 
There are significant issues with this app, which I think can be grouped into two categories: poor app performance and poor user experience considerations. App performance: app repeatedly crashes, even with few background apps running and phone plugged in. This manifests as either data loss or a "signal loss" alert. I estimate five to seven times per week where this happens. App is unresponsive to touch, especially when responding to an alarm or alert. I have video of me swiping, tapping, shaking, etc. for two minutes waiting for app to respond. The real problem here is that you can't tell from the screen if you're looking at a real value or a frozen screen from hours ago, especially at a quick glance. UX: the idiocy of the "replace sensor" alarming is almost beyond description. A default period of six hours prior to replacemement, you get an alert. When do people change sensors? Most people, after a shower. When do you take a shower? Most people, in the morning. So when you get this six hour forewarning? IN THE MIDDLE OF THE NIGHT. You can't modify or disable this alert. If you place your phone in "Do Not Disturb", it also silences the other alarms, such as high or low glucose, which are half the reason for having the system in the first place. The system is slow to respond to rising glucose (that's the nature of the sensing tech, not the app's fault), but this leads to repeated low blood sugar alarms after the hypoglycemic event has been treated. Even worse are high blood sugar alarms, where one is waiting on insulin to take effect (an hour or more), while every thirty minutes the app is screaming at you. These alarms need a "snooze" capability, where they can be silenced for a time period so the biologic effects of either hypo or hyper treatment can be sensed without disturbing the user. I would suggest user-adjustable from 15 minutes to 60 minutes. And while I haven't confirmed this, I'm fairly confident that the app alarms when passing either the hypo or hyper threshold in BOTH directions. Meaning, you get a low alert, eat carbs for that, then get another as you move up past the low threshold. The system is amazing in one respect - I don't have to carry yet another device with me to have a good idea of what my blood sugar is. The capabilities are so close to being superb - there will always be feature requests (data pump to dropbox or similar, as an example), but a good solid scrub of the code and some cleanup of the user experience would do so much here. So in the end, I'm thrilled that there is an app solution. But straightening out these issues would advance the app significantly and I hope to see improvements in the next update.
 
Why create a complication with no data? 
Why doesn't the complication read me my number/trend arrow? Infuriating. Further more, why can't dexcom issue a statement addressing this? How about some insight into this? We pay thousands of dollars a year for this product, some insight would be nice.
 
Incorporate insulin dosing 
So I use the app called RapidCalc by Gilport (Google this if you can't find in the App Store and you will find gilports website. It's an Insulin On Board Dosing Calculator . It's awesome! Every since taking a pump vacation and using MDI, I use Rapid Calc. If Dexcom could incorporate a calculator such as this in their app I would only have to rely on Dexcom app instead of both apps. I think this Dexcom app has the base for it because it allows u to enter Carbs and Insulin units, just need to be able to insert pump settings into the Dexcom app and add the Insulin on Board calculator for MDI non-pump users. Please take a look at Rapid Calc by Gilport so you can see what I mean. For now I will be stuck with both apps but ideally would be so convenient to use just Dexcom for calculations! Thx for reading!
 
Some issues 
I wish I could turn off the phone storage alert. The app takes over the sound on my computer when it's open. Both of these are super annoying!! I need this app to make my life easier.
 
Useful, but lacking functionalities 
It is really nice to be able to see the glucose value and trend graph by the turn of your wrist, however, a few improvements would go a long way: - See glucose value and direction straight from the complication shortcut - Be able to snooze alarms following the app settings (snooze for longer periods than the default watch 5 minutes). This is a big deal for me as it is annoying to keep snoozing that frequently unless you open the app on the phone and snooze in there.... - Enable the crown to switch the history time settings. A few of these have concerns have been raised by other users quite some time ago, so I hope that you guys are already addressing those and consider new ones.
 
Life changing 
Great app, does its job wonderfully. This app plus the G5 have made a huge impact on my daily diabetes management. Love the new widget! Only wish is being able to pinch zoom in/out and pan the graph in the app when the phone is set to landscape mode, and be able to write in my own words what food I had when adding a Carbs event (in addition to the carbs value).
 
Ok. Close to good. Far from great. 
Love that my phone and watch can see my glucose. Love that others can see it as well. Hate hate hate the following: 1 - have to choose between alerts on your phone or on your watch. Can't have both or just phone when app is connected. 2 - I just entered in a high glucose value. A couple of minutes later the alarm is going off due to high glucose. Thanks, I was aware before you were! 3 - an alert comes across the watch... Yeah hit that dismiss button. Does nothing for you and will keep repeating every five minutes until you dismiss it on your phone. 4 - beep beep beep comes across my car speakers at a much louder rate while trying to have my phone call. My glucose low? No! Says I closed the app and I won't get alerts. Liar! Haven't touched it in hours! You closed yourself! Items I don't hate but wish it could do: 1 - make the watch more interactive and not just a display. 2 - allow a "snooze" feature on alarms for whatever period of time you pick. This will help with lows or highs when you've corrected but waiting for the sensor to pick up the newer ratings. 3 - sync with the tandem insulin pump (G5)
 
Caution: iOS 10 color fiasco 
Caution: If you update to iOS 10 Beta 2 or Beta 3, the icon colors in the app are dark grey on black, making them nearly impossible to see. The app itself if good, but as others have noted, it would be nice to have a pinch zoom feature, allow scrolling the graph in portrait mode, and an active watch complication. The watch complication is my biggest desire. I don't need a shortcut, I need a) a small complication with the number and trend, and b) a large complication with the graph line.
 
Awful but what choice do I have? 
Love the sensor, hate the app. I have called dexcom support a few times and always gotten the runaround. Every night, I park my phone on my nightstand. About 2 feet away from where I sleep. And yet every single night, I get "signal loss" and no data from about midnight onwards. So frustrating. It seems to require a restart in the morning to get the sensor talking to the app again. If I don't restart the app it never goes out of "signal loss" no matter how close I am to the phone. Second huge issue is that when it alerts me to a high glucose it's really hard to dismiss the pop up and associated jarring claxon sound. Again multiple restarts are required. And yet what choice do I have? I love the sensor itself so I am not going to switch brands.
 
Frequently disconnects, does not adhere to alarm repeat settings 
Though this app is extremely valuable, it frequently disconnects, which can be dangerous. Also, despite having my high glucose alert set to repeat once every hour, it still repeats every 5 minutes. My glucose takes the to decrease! I don't need to be bothered so frequently. This makes me want to turn my high glucose notification off. Additionally, my followers frequently aren't updated if I'm low. That's the whole reason I got this app. The unreliability of this app makes me feel unsafe!
 
Latest iOS? Not working with Apple Watch? 
Worked fine, but now I always get a message at my watch saying to check the G5 app on my phone :(
 
Needs a few things to be perfect. 
Overall, pretty good, easier than entering your data on the Dexcom receiver (With it's tiny, yet blinding screen!🙄). I would love if you guys could add a way to mark insulin doses in 3 categories: long acting, short acting and correction.
 
Good but not Great 
I've been a T1 since 2011 on a very low carb diet to keep my blood sugars flat. This app helps a lot with management, but these additions are sorely needed: - Ability to set a high blood sugar alert lower than 120 (e.g. 100 or even 90). Since I never get sugars as high as 120 the app never alerts me even when needed - Ability to lower the scale from 300 to 150 or even 120. Right now a lot of real estate is wasted on space where my blood sugars are never going to be. - Ability to keep the app on and my phone lit at all times. This app is usually on my screen when I work or drive with my phone plugged in. It's annoying that one has to continuously tap the phone to see my blood sugars - Ability to scroll back in time for the past 12h or so. It's annoying to have to check both the app and Dexcom Clarity to see the whole blood glucose picture. - Ability to set the background of the phone a bit darker so one doesn't get blinded when checking blood sugars at night.
