Metronome and Tuning

A tuner and metronome on one screen. No ads, no in-app purchases, just a tuner and metronome.

Tuning and Metronome is a practice companion for string players: a chromatic tuner and a metronome running at the same time, on one screen.

Watch your intonation on a precise semicircular gauge while an audible beat keeps time. The tuner uses the YIN algorithm for fast, accurate pitch detection across the full chromatic range - play any note, not just violin strings. The metronome is driven by the audio render timeline, never a timer, so the beat stays rock-solid and the pendulum swings in perfect time.

Built for real practice: • Simultaneous tuner + metronome - hear the click while you watch the needle. • Click rejection - the tuner ignores the app's own metronome clicks, so a sustained note stays stable instead of jumping with every beat. • Configurable A4 - set concert pitch from 415–466 Hz (presets: 415/432/440/442/443/444, plus a fine slider). • Multple clap sounds - Clap 1 and Clap 2, each previewable, with independent volume. • Live BPM changes - the beat and pendulum track your tempo without skipping or doubling. • Distraction-free dark UI - tuner gauge up top, pendulum metronome below.
