Motion Sense : Control by wave for Android

A free program for Android, by Mohamed Saber.

Do you ever find yourself in a situation where you can’t touch the screen of your smartphone or tablet because your hand is wet or you’re using a screen protector? If so, you’ve come to the right place. We at Motion Sense want to make your life easier by providing you with the solution you’ve been looking for. We’re working on a new version of the app that will provide you with the control you’ve been looking for. 

You can control the music, make the phone call, or whatever else you want to do. The best thing about this app is that it doesn’t require any extra hardware. The app can run on any phone with a built-in microphone and it doesn’t require any extra hardware.
