'Clap & lock or unlock screen' works in background and detects sound of clapping. When you clap your hands the phone lockscreen changes its state (it will unlock or lock your mobile phone screen).

Lock phone by clapping is a very useful tool to prevent access to your phone and you can do it on remotely - just by clapping your hands. It can be also used to show your friends how innovative phone you have!

Clap once to turn on lock on your phone screen. Clap twice to turn the lockscreen off and use unlocked phone as usual!
