Changelog

New bass tuner for 4- and 5-string bass, including Drop D. New chromatic tuner for any instrument from B0 to C6. Nine alternate guitar tunings, each with its own page: Eb Standard, D Standard, Drop D, Drop C, Drop B, Open G, Open D, Open E and DADGAD. You can now save your own custom tunings, shift a whole tuning up or down, and keep reference notes playing while you tune by ear.

Guitar and ukulele tuners in English and German. Microphone detection and reference tones run locally in your browser. No account is needed, and your audio is never stored in the cloud.
