The best looper for iOS so far!

This one really deserves 5 stars! The interface is well designed and very easy to use, functionality is all there, you get more tracks than any hardware looper, plus it supports all the current standards on the iPhone and iPad like virtual MIDI and Audiobus.
the only things I missing are: pitch shifting and reversing the loops, I hope they will add that sooner or later.
