From the developer:
Are you looking for better control of the sound volume in OS X? BetterVolume is a replacement for the stock volume control that provides more granular control of the volume level.
BetterVolume allows you to use the shift key when changing the volume to adjust the volume in quarter-level increments. Also, it gives you the option to show the current volume as a number.
