Tuner & Metronome
Two things every practice session needs and every phone app buries under ads. The metronome schedules clicks on the audio clock so it does not drift; the tuner listens on the microphone and never records.
Metronome
Beat one is accented. A polyrhythm lays its hits evenly across the bar on a lower voice — 3 per bar against 4 beats is the classic three-against-four.

About this tool
Tuner & Metronome covers the two things every practice session needs, without the ads most phone apps bury them under. The metronome schedules clicks on the audio clock so it doesn't drift over long sessions, with accents, subdivisions and polyrhythm layers; the tuner listens on your microphone with a cents readout and reference tone, and never records.
How to use it
- Set your tempo and choose accents or subdivisions for the metronome.
- Layer a second polyrhythm if you're practising against it.
- Switch to the tuner and allow microphone access.
- Read the cents readout, or play the reference tone to check by ear.
FAQ
Is this free?
Yes — the tuner and metronome are both free and unlimited.
Does the tuner record my playing?
No — it listens live to show pitch and cents, and never records or uploads audio.
Does the metronome drift over a long session?
No — clicks are scheduled on the audio clock, not a JavaScript timer, so it stays tight.
Can it do polyrhythms?
Yes — layer subdivisions and polyrhythms alongside the main click.
Play one note at a time. The needle holds the last confident reading for a second so it does not flicker between plucks. Reference tone plays the nearest note when a reading is held, otherwise A4.
