Two tools, open to everyone.
No account, no download, no ads. Open one, use it, close the tab. They are the same metronome and tuner that sit in the app, on their own pages.
Metronome
40 to 208 beats per minute, four tempo presets, and a swinging arm. Every click is scheduled on the audio hardware clock, so the beat holds while the page does not.
Open the metronome
Tuner
Chromatic, down to 27 Hz, with the browser voice-call processing switched off and a note lock that stops the reading flickering between neighbors. The audio stays in your browser.
Open the tuner
Free, no ads, part of MakesPerfect. Create an account if you also want assignments, a practice log and a library of pieces you can hear.
