The only metronome app you need.
Ive tried other metronome apps for the iPhone and have found them to be a bit inaccurate. The space between the beats changes ever so slightly causing the time to rush and lag. This is the ONLY metronome app Ive used that keeps PERFECT time. For the more advanced user, the programming capability of this app is second to none. Programming different time signatures/subdivisions is a breeze. This app is a serious practice tool for the musician who wants to play along to odd time signatures. And the mute feature is a great way to improve your basic sense of time as well. GET IT!!
