Well-made app, simple, and straightforward. A few suggestions:1. Ability to play polyrhythm in background while using a different app2. More than two rhythms (e.g. 3:5:7 or 3:5:7:11)3. increment/decrement tempo with plus/minus buttons or (even better) auto accelerate/decelerate4. When only two rhythms, option to assign one rhythm to left audio channel and the other rhythm to right audio channel. This would help in training the left hand to sync with the left ear and right hand to sync with the right ear.5. Option to make sounds more like clicks rather than drums because, when the tempo is very fast, clicks would be easier to hear as distinct events.

This app is so simple and so worth the money. I’d just love to be able to add more rhythms instead of just being able to manipulate the 2!

Perfectly simple, great app, worth the price!My only complaint is that touching any of the settings disables the play button; it would be better if I could isolate the top/bottom beats, adjust tempo, and change beat patterns without constantly needing to spam the play button with my other hand. Otherwise this is a 5 star app!

The title of this review should be enough. This app is awesome for those of us looking to practice polyrhythms quickly and electively. Intuitive interface, great sounds, and not limited to standard, common polyrhythms. Great work!
