Sample-accurate timing
No drift, no jitter. Every click is scheduled to the audio frame, so the tempo stays solid through hour-long sessions.
Live on App Store & Google Play
Metronome, done right.
Sample-accurate timing with no drift over long sessions, a low-latency audio engine, and everything a practice room actually needs. No sign-up, no subscription, no clutter — tap, set your tempo, and play.

What's inside
Everything you need, nothing you don’t
Built for daily practice rather than for a feature list.
Tap tempo and presets
Tap any tempo to lock in the BPM anywhere from 30 to 300, with ±1 and ±5 buttons and unlimited saved presets to flip between songs.
Time signatures and subdivisions
2/4, 3/4, 4/4, 5/4, 6/8, 7/8, 9/8 and custom meters, with quarter, 8th, triplet and 16th subdivisions.
Editable accent patterns
Emphasise any beat in the bar. Long-press the beat row to set each one to silent, quiet, normal or accent.
Five sound packs
Wood, click, beep, cowbell and drum kit — from a warm mid-range wood block to a sharp click that cuts through a loud room.
Practice tools
A speed trainer that ramps the BPM as you play, a bar loop that stops after N bars, a lead-in count and a practice timer.
