Clap to Find

screen needs to be idle (which it usually is when you leave your phone 'around here somewhere'). Then, as long as the app is running and the screen is idle, all you have to do is clap your hands a few times to instantly find your Android. Clap to Find is a really useful app that can help you avoid losing your smartphone or tablet ever again. A few claps as you walk around the house and, in a matter of seconds, you'll hear exactly where you left your device.
