Timeriffic - does one thing: it can mute or un-mute the global Android ringer at a specified time of the day.
Example: Got class M, W, F at 8am, use Timeriffic to:
* un-mute your volume from 7am - 8am during the ride to class,
* switch to vibrate at 8am,
* and then back to full volume at 9am.
(If you're a grownup substitute "class" with "work").
· Time: Finite, and now well managed.
· Turn mute and vibrate on/off custom to your schedule.
· Simple. Easy. Timeriffic.
· No useless features.
· Won't hurt your battery!
