Shhhh

Automatically silences the ringer at the beginning of an event and then restore it to normal at the end of the event so you don't have to think about it. Shhhh can be activated by scanning a Calendar event QR code which can be generated at http://zxing.appspot.com/generator/. Shhhh can also be activated manually by selecting Home instead of scanning and then setting a start time and end time.
