Clay's Metronome

Sample-accurate timing with Apple Watch haptic sync. Polyrhythms, swing, accelerando, count-in, silent-beat drills & 5 timbres — built for serious practice.

Clay's Metronome is a professional-grade practice tool built for musicians who need rock-solid timing and flexible rhythm training.

SAMPLE-ACCURATE TIMING A native AVAudioEngine powers the beat scheduler — no JavaScript timers, no drift. Every click lands exactly where it should, even in background mode.

POLYRHYTHMS Practice two rhythms at once — 3 against 4, 5 against 7, anything you need. Each track gets its own distinct sound so you never lose your place.

SUBDIVISIONS & SWING 8th, 16th, and triplet subdivisions with adjustable swing. Dial in a jazz shuffle or a funky 16th-note groove.

SILENT-BEAT TRAINING Randomly drops out non-accented beats so you have to hold the time internally. Set the percentage from 0–50% and test your internal clock.

COUNT-IN Get 1, 2, or 4 bars of clean clicks before practice starts. Silent-beat training and drills automatically kick in after the count-in.

ACCELERANDO DRILLS Ramp the tempo up by a set number of BPM per bar to a target speed, with optional auto-stop after N bars.

APPLE WATCH COMPANION Haptic-only click on your wrist, controlled from your phone. Keep your phone in your pocket and feel the beat.

PRESETS / SETLIST Save your full setup — tempo, time signature, accents, sound, polyrhythm, subdivision, swing, drill, count-in, and silent-beat settings — as a named preset. Recall it instantly for your next gig or practice session.

5 CLICK SOUNDS Click, wood block, clave, cowbell, and digital beep — all generated in-app, no audio files needed.
