Volume Zone automatically adjusts your media volume based on where you are. Set it up once, and your phone takes care of itself. How it works Create a zone for any location — home, work, the gym, a library. Assign a volume level and notification tone to each zone. When you arrive, Volume Zone silently applies your settings. When you leave, it restores your defaults. Why you'll love it No more blasting music when you walk into the office. No more missing calls because you forgot to turn the volume back up at home. Volume Zone handles all of it in the background, without you lifting a finger.
