Online Tuner for Guitar, Bass and Ukulele

Yes. It is free, needs no account and works in any current browser on a computer or phone.

No. The sound is analysed live inside your browser and thrown away straight after. Nothing is recorded, stored or sent anywhere.

Guitar, bass and ukulele in standard tuning have their own modes. Chromatic mode works for any instrument, any tuning, and voice.

Within about a cent on a clean, sustained note. Play one string at a time, mute the others, and tune in a quiet room for the steadiest reading.

The reference can be set from 430 to 450 Hz. For 432 Hz, type 432 in the A4 box and tune as usual.

Press Start Tuning and allow the microphone. Pick your instrument, play one open string at a time and let it ring. The needle shows how far the note is from the nearest string: left is flat, so tighten the string; right is sharp, so loosen it. When the needle centres and the note turns blue, that string is in tune.

Guitar: E A D G B E, low to high. Bass: E A D G. Ukulele: G C E A, with the G tuned high (re-entrant). Chromatic mode shows the nearest note for anything else, including alternate tunings, drums with a tuned head, and your voice.

Most music is tuned to A4 = 440 Hz, and so is this tuner by default. If your band or a recording sits a little higher or lower, set A4 anywhere from 430 to 450 Hz and every string target moves with it.

No. The free tools need no account and no download. They run in your browser, and nothing you play or drop in is uploaded.
