Watch Tuner

Simple Watch Instrument Tuner is a chromatic tuner that runs entirely on the Apple Watch. Raise your wrist, play a note and tune until the needle turns green. Orange means you're flat, red means you're sharp.

It's made for rehearsal: your phone can stay in your case, and there's nothing to set up. Add the Tuner button to your watch face and it's one tap away.

Good to know

• Concert pitch. Like most tuners, it shows the concert note. On a B♭ trumpet, clarinet or tenor sax, a written C reads as B♭.
• Any instrument. Brass, woodwinds, strings, guitar, bass and voice.
• Two settings, that's it. Reference pitch (A = 430 to 450 Hz) and sharps or flats.
• Private. Sound is analyzed on the watch and never recorded or sent anywhere.
• Free. No ads, no account. Needs watchOS 10 or later.

No watch? The free BANDROOM.GAMES tuner works in any browser and can transpose for your instrument.
