Volumizer

Volumizer will automatically set your volume when your phone boots.
Simply drag the slider to the desired percentage and save settings.
The next time your phone boots the volume will automatically set.

If there is enough demand I will create an interface where the user can select when the volume should be set instead of only on boot. For example a drop down that gives options to choose when someone calls, screen turns off, or when the screen turns on the volume will set to specified volume.
