SmartSilence for Android is an app that allows you to avoid the faux pas of having your device’s ringer test its vocal chords at those oh-so inconvenient times. By allowing you to schedule time periods when you’ll definitely be requiring total silence from your smartphone, you can avoid the interruption of the call or text tone that, for some reason, always seems to ring loudest when you don’t want it to at all. More details and the download link can be found right after the break.
