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.

FREE FEATURES
• Studio-grade timing engine, 1–800 BPM
• Any time signature: 1–32 beats per bar, counted in quarter or eighth notes — 5/4, 7/8, 9/8, 12/8 and more
• Accents and groupings such as 2+2+3 for odd meters
• Two-voice polyrhythms such as 3:2 or 4:7

PRO FEATURES — one-time purchase, Family Sharing supported
• Up to 5 polyrhythm voices, each with its own sound, color, accents and pattern
• 18 sound banks (10 metronome + 8 polyrhythm)
• 16 built-in rhythm patterns and a custom pattern editor with real notation — even a different subdivision on every beat
• Presets: create, edit and duplicate, with notes such as the key or capo shown on stage
• Setlists: songs in order, each with its own tempo, notes and auto-advance on the downbeat — the app reopens on the same song if it closes mid-gig
• Practice sessions: Coach mutes bars to test your inner time, Automator ramps the tempo by bars or seconds, and session goals keep you on track
• Practice log: day streak, minutes per day and your top-tempo progress
