Dump all books. This is the future!

This app is the only tool I am using these days to teach and to practice reading rhythmically.
Love it to death.
Can not recommend it enough. So worth the price of admission.

Excellent app for drummers!

Practice never gets boring, because there is always a new challenge to be generated. Highly recommended for anyone wanting to master odd time signatures and polyrhythms.

I LOVE this app. If you're struggling with rhythms, especially sight reading, or just want to practice something new, get this. Amazing for percussionists but also very useful for other instruments. Practice with the player or on your own. The only thing I would change is the ability to have other voices than a snare. Must have for beginners and Advanced players alike!!
