Practice tools that respect your time

A metronome should be invisible — you set your tempo, press play, and it disappears into the background while you focus on playing. That's what PlayMetronome is built for. No aggressive advertising during a practice session, no popups breaking your concentration. Just a precision metronome using the Web Audio API's lookahead scheduler — the same technique used in professional DAW software — so the beat never drifts even after 30 minutes.

The guitar tuner works directly from your microphone. Open the page, grant mic access, play a string. The autocorrelation pitch detector shows you the note name, octave, frequency in Hz, and how many cents sharp or flat you are. No app to install. Need to log a practice session? timer-hub.com pairs well for timing your warmup blocks.

For producers programming delay and reverb times to match a track's tempo, the tempo converter gives you millisecond values for every subdivision instantly. And the interval trainer is one of those tools guitarists always mean to use more — five minutes before a jam session is genuinely useful.

Is PlayMetronome free to use?
Yes, completely free. All tools work in your browser with no download, no account, and no subscription. The site is supported by non-intrusive ads that never appear while you're actively using the metronome or tuner.
How accurate is the online metronome compared to a hardware metronome?
PlayMetronome uses AudioContext.currentTime for scheduling — this gives timing precision of approximately 1ms, comparable to dedicated hardware. Traditional browser-based metronomes using setInterval drift by 10–25ms per beat, which adds up fast in a long practice session.
Does the guitar tuner require microphone access?
Yes — the tuner uses getUserMedia to access your microphone in real time. Your audio is processed entirely in the browser; nothing is transmitted to any server. You can revoke access in your browser settings at any time.
What browsers are supported?
Chrome, Firefox, Edge, and Safari (iOS 14.5+). The Web Audio API and getUserMedia are available in all modern browsers. If you're on an older device, the metronome will work but the tuner may not.
Can I use the metronome on my phone while teaching a student?
Absolutely. The metronome page is optimized for mobile — large touch targets for BPM adjustment, a tap tempo button you can hit mid-lesson, and the screen stays active while the metronome is running.
