Want a quick way to mute your Android smartphone? Well, a new Android App called RD Mute mutes your smartphone when you place it facedown on a surface. It also has some other features to notify callers you are driving.

The application is free to download and can be started by flipping the phone on its face or when the GPS registers a traveling speed of 31 mph. It will automatically SMS anyone who calls you while driving to notify them that your at the wheel and will call them back later. Pretty handy app.
