Free online metronome

A real metronome, in your browser.

This is a mechanical metronome: a swinging pendulum, a brass weight you drag along the Maelzel scale from 40 to 208 BPM, 2/3/4 beats per bar with a bell on the downbeat, and tempo terms from Largo to Presto. No ads, no account, nothing tracked, it runs entirely in your browser.

The same metronome lives in the Notalune app, free.

Notalune is an iPhone app that shows you the name of every note, right on your own sheet music, and this exact metronome ships inside it, free and unlimited, with tap-tempo (knock the wood in rhythm and it matches you) and per-piece tempo presets. When it reads your music and isn't sure about a note, it says so instead of guessing.
