If at home, you are not usually paying a lot of attention where you leave your smartphone....clap for it !

This app will make your smartphone to respond to your claps by emitting a sound.

Before the normal use, in which the smartphone is listening for claps when it is typically left unattended, the user is given the chance to test the behavior of the clap recognizer.

A simple sequence of 3, 4, or 5 claps is recognized. The user can set this quantity.

The app offers an enhanced (premium) level of use, as an in-app purchase product. The level allows the user to choose the sound the app uses to respond to the user's clap sequence.
Those ones added are continuous sounds, differently from the default single isolated "Toc" sound.
