Customer Reviews

Metronome unusable

This app has everything I was looking for in a practice aid, but unfortunately the metronome is way too buggy to use, even if you really want to make it work. I would definitely recommend NOT buying this app, since there are better apps out there for rudiments, and the metronome is just plain broken. Wish I could get my buck back.

Not enough rudiments

A good app in theory, but for a paid app it should have a lot more to it. The rudiments it shows are very basic, but there is only a few. It is also lacking accents on the play function of the rudiments. This app needs some work before it is worth paying for.


The rudiment sounds are from a cheap drum machine. They are poorly accented and tempo and accents are not adjustable so you get NO idea if what you are playing is correct.

Nothing to learn or practice in this app.
