polybeat app for iPhone and iPad

polybeat is an advanced and extremely flexible drum and percussion sequencer able to generate complex polyrhythmic and polymetric rhythmic patterns.

nb: polybeat does not make sound by itself, you will need to load it in an AUv3-compatible host (such as AUM, Audiobus, ApeMatrix, Nanostudio 2, etc.) or connect it to an external drum machine, synthesizer, computer or any other sound generating device.
