What about "The Silencer"?

[BigOSoftware]

Hey guys, I just created an app called "The Silencer" and would love to get some feedback. Heres a quick rundown of the features/functionality:

• Immediately after starting the app, it gives you the option to quickly silence your phone for a set duration of time, or until a specified time, and after that is over your ringer goes back to what it was before
• Monitors any calendars you tell it to, and when you have a meeting/event automatically puts your phone on silent/vibrate (dependant on your choice) for the duration of the meeting/event
• Allows you to monitor and selectively observe and ignore calendar events up to 12 hours in advance
• Automatically ignores any current events if you take the phone off silent

Thanks guys!
