Use this simple application to quickly toggle your phone ringer on/off (from ringing to silent and back to ringing again). It is particularly useful for those Android phones with no quick settings bar on the notifications pull down, such as HTC and Nexus devices. Note you cannot set to Vibrate mode with this app.

Add the widget to your home screen to use the app. The widget shows green when the ringer is on, red when the ringer is off, and amber when the phone is in vibrate mode (note will be amber if phone set to vibrate by alternative means).

Note that the widget colour also updates if the ringer is changed by some other means (such as the volume key or from the system settings), unlike some of the other toggle widgets available, so you always know the ringer state from the widget colour.
