With BuzzOff you can set an alarm to re-enable your ringer after the movie ends!
Or you can have it turn your ringer back on after you move a certain distance - easier to use than Locale.
It's activated when you silence your ringer using the volume buttons. You don't need to remember a special app! Once your ringer is off, it asks you how long to stay silent. Never miss another important call.
Great for class, the office, movies and sleep.
