No enhanced incremental control in fact.

I thought this would give me superior control of volume...not looking for more volume or more bass, just FINER CONTROL OF VOLUME. The control face shows incredibly fine control but in fact the AUDIBLE changes take place at the same incremental jumps already in the iPhone. Looks like it is doing something but isnt doing anything that the iPhone doesnt already do in terms of volume control. That makes this app worthless to me.
