How to use the Metronome
- Set the tempo with the slider, the ± buttons or the arrow keys — or tap the tempo with Tap tempo or the T key.
- Pick a time signature; beat one is accented.
- Press Start or Space.
Accurate timing
Clicks are scheduled on the Web Audio clock a little ahead of time, so the beat stays steady even if the page is busy — unlike timers, which drift. The tempo name follows the classical markings: Largo (40–60), Adagio (66–76), Andante (76–108), Moderato (108–120), Allegro (120–156), Presto (168–200).

Frequently asked questions
How does tap tempo work?
Tap the button (or press T) in time with the music; the BPM is the average of your last taps.
Does it keep time in a background tab?
Audio scheduling continues, but browsers may slow background tabs; keep the tab visible for long sessions.
Is anything uploaded or recorded?
No. Everything runs in your browser; results and settings are kept on this device only.
Can I install Metronome as a web app and use it offline?
Yes. Metronome is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
