Most of the time when you are going for a meeting, you keep your phone into silent mode, but once the meeting is over, you forget to change it back to normal mode. As a result you might end up with missing calls. UnSilencer is a nice app for Android which allows you to set your phone to silent mode for a particular time period and once it is over, your phone returns back to normal mode. You can set the phone to silent mode for 30 minutes, 1 hour, 2 hours or custom time period.

A nice tool for people who use the Silent mode on phones pretty frequently.
