Mute-o-matic is an ingenious app that changes the call settings on your phone according to your planned meetings and events.
By entering details of meetings to the app, you can programme your phone to switch itself to silent mode without having to remember to do it yourself. The app also enables you to set a standard reply message to anyone who might call you when you're in that meeting.
Mute-o-matic also allows different settings to be applied to different callers, so you can set the phone to ring if your other half calls while silencing everyone else.
