Finally a sound detector for your device. This application will measure decibels around the phone. It will create an alert every time the level goes above 90 dB. This application is perfect many purposes. Just assume a teacher that is in the middle of a midterm and has to go to the bathroom, just turn on our state of the art sound detector and when the teacher comes back he/she will be able to know if someone spoke, there are several uses for this app, just think about it.
