Clap to lock or unlock phone prank

Our app detects clapping sound and locks or unlocks your mobile phone. It's a good way to prevent strangers from using your phone! When you see that somebody is taking your phone and using it - just clap your hands to lock the Android system! Clapping detection works in background so it won't grab anyone's attention.

On first use you have to give permissions to the app so it could lock/unlock your mobile phone screen. When you will do that just activate our background service and in proper time clap your hands to lock or unlock Android screen.
