Rhythm Trainer BPM

Precise metronome and chromatic tuner in one. Practice 1–400 BPM, tune by cents, run tempo from Apple Watch. One-time Pro — no ads, no subscription.

Every practice session needs a tempo you can trust. This metronome and chromatic tuner is built for musicians who want precise BPM, saved setups, and no ads — one purchase, no subscription.

ACCURATE TIMING, EVERY TIME Set 1–400 BPM on iPhone and iPad with a precision slider and ±1/±5 steps. Choose common and Pro meters, custom accents, and quarter, eighth, sixteenth, or triplet subdivisions. A pendulum animation and downbeat flash keep you locked in.

CHROMATIC TUNER, WHEN YOU NEED IT Switch to the Pro tuner without leaving the app. Live pitch detection, a clear cents needle, and master tuning from 428 to 452 Hz. A reference drone holds the master pitch so you can tune by ear.

Home Screen and Lock Screen widgets, plus Live Activity and Dynamic Island, keep tempo in reach. Phone and Watch do not stay in sync — the Watch runs on its own.
