This app converts light level to vibration , the brighter the light the more it can be felt. The idea is to use the light level so that a Blind person could make out bright areas in a room, and use to find doorways ect. So he/she would use the phone to scan the room, download sensorviewer first to test your phone has a light sensor. Press meun button to adjust the Sensitivity 100% will give a strong vibration in Dim light. 50% seems best for indoors. Feedback would be great. less
