Amazing once you learn how to use it!

This app has a pretty high learning curve, but once you learn how to use it, it is extremely versatile! It can do many things that the Dr. Beat cannot. If you just need a simple quarter note click, this app is
overkill. If you need to have polyrhythms, set lists, weird odd time groupings,
this is the app for you!
