ActivePlayer

Set two different volumes for when you're in motion versus when you come to a standstill

Uses:
-Snowboarding - no longer have to take off gloves to lower volume or pause music
-Jogging/Running - Great for communication at stop lights or for crossing traffic
-Cycling
-Driving or boating
-etc...

Works with your built in media player, soundcloud, pandora, or any other music application.

ActivePlayer allows the user to set an active and rest volume, so when the user is in motion, as triggered by an algorithm parsing buffered accelerometer data, the user's 'active volume' is used for media playback and when the user is no longer in motion the volume is restored to the 'rest' level or the music is paused depending on settings.

Since the app uses movement and not speed it works in almost all applications, including running on a treadmill
