Metronome
Steady click with an optional accent on beat one, tap tempo, selectable time signatures and click sounds — including a spoken count, a silent visual-only mode, and haptic vibrate on supported phones — plus a speed trainer that ramps you from a start tempo up to a target. The time gym adds polyrhythm practice (3:2, 4:3, 5:4, 7:4), a gap click that goes silent for whole bars, and a random beat drop, all stackable. Pair with exercises to lock in timing.
Metronome
Set a tempo, pick a time signature and click sound, and hit Start — or tap the beat. Turn on the speed trainer to ramp from a start tempo up to a target.
Stopped — press Start or Space to begin.
Speed trainer
When enabled, Start begins at the start BPM and speeds up until it reaches the target. Stop resets it.
Time gym — polyrhythm, gap click, random drop
While polyrhythm is on, the bar length follows X (the time-signature picker is ignored) and both voices meet on beat one.
The lamps keep sweeping through silent bars and dropped beats — your internal clock carries the time. All three modes stack with each other and with the speed trainer.
Tip: press Space to start or stop when focus is not in a field.
