[App Suggestion] Mute your phone during calendar events for AT&T Galaxy S3

[tplace 1976]

I'm wondering if someone is using any particular app to mute you phone's notifications/ringer during an event on your calendar. Particularly your Exchange Calendar (since I really don't use any other calendar).

I've found a few out there, but they are all kind of sketchy as far as how well they work. The one I'm using now does a refresh of your calendar on an interval basis, and I've found that it may not mute at actual start of the event (but within 10-15min) and it doesn't unmute at the end either (same refresh interval issue) and will do so some time after.

Thanks in advance!
