Metronome
A precise, free online metronome with tap tempo, adjustable time signature, and an accented downbeat. Runs entirely in your browser.
120
Beats per minute
How it stays in time
Beats are scheduled ahead on the Web Audio clock rather than fired from a JavaScript timer, so the tempo doesn't drift when the tab is busy. Nothing is uploaded and nothing is recorded — the click is synthesised in your browser.
