Wrist Tuner – Chromatic Tuner

Measure pitch directly on your Apple Watch. Wrist Tuner displays live frequency in hertz, the nearest note and octave, and deviation in cents. A clear linear meter shows whether a note is flat, sharp or centered, helping you make small tuning adjustments at a glance. • Live frequency, note, octave and cents readings • Flat-to-sharp meter with a centered confirmation • A brief held reading as a note fades • One-tap Start and Stop controls • Chromatic note detection with A4 = 440 Hz • Audio processed locally on your Watch, without recording or transmission Designed for one note at a time. The supported range is C2–F5 (65.41–698.46 Hz), covering standard guitar and alternate tunings within that range. You can also check individual piano notes within the supported range. Wrist Tuner runs independently on Apple Watch. No account or internet connection is required for pitch measurement. Requires watchOS 27 or later and microphone permission.
