Poly Metronome

Poly Metronome is a precise, modern practice tool for musicians who want more than just a click. Set any time signature, shape odd meters with accent groupings, layer polyrhythms, then save your setups as presets and setlists — or build up speed with practice sessions that track your progress. A clean interface scales from iPhone to iPad, with a live pulse ring that shows every voice and accent at a glance — and stays in sync with the sound on the speaker, headphones, AirPods or AirPlay.
