Terrible.

Looks nice... But thats about it. The tempo is hard to control, and more importantly, THE TEMPO IS OFF ALL THE TIME!!! Check it with a REAL metrnome and youll see what I mean. I would have rated this with 0 stars if I had the option! This app is COMPLETELY useless to musicians. Try the iTick app... which is accurate, for one. :)
