Tuner Wear: Guitar Tuner App

Tuner Wear is a chromatic guitar tuner for Android phones and Wear OS smartwatches. Tune your guitar, bass, violin, or ukulele from the watch on your wrist, without taking the phone out of your bag.

🎯 WHAT YOU GET

Chromatic tuner
A guitar tuner that detects every note in the 12 tone scale from any string instrument. Real time pitch in Hz, cents deviation, and note name. Fast and stable, even in noisy rehearsal rooms. Built for beginners and gigging musicians alike.

Chord dictionary
240 chord definitions: 12 dyads (power chords), 72 triads, 120 tetrads (sevenths and extensions), and 36 pentads. Major, minor, seventh, suspended, diminished, augmented, ninth and beyond. Over 600 diagrams for guitar (acoustic and electric) and 463 for ukulele. Open chords, barre chords, and alternative voicings. Useful for jazz, blues, rock, folk, country, bossa nova, fingerstyle, and worship. Left handed and right handed diagrams. Each voicing plays sampled audio so you can hear before you play.

Metronome
40 to 240 BPM. Time signatures from 1/4 to 12/8. Tap tempo and a visual beat indicator.

A4 calibration
Set the reference pitch from 430 to 450 Hz. Standard concert pitch is 440 Hz, but many European orchestras tune to 442 or 443 Hz. Use 432 Hz for natural tuning, or lower references for period instruments and historically informed performance. The tuner adjusts every note relative to your chosen A4 so the whole instrument stays in tune at the reference you want. Premium.

Six languages
English, Português, Español, Deutsch, Türkçe, Français.

🎸 WORKS WITH

Guitar (acoustic, electric, 12 string), bass, ukulele, violin, viola, cello, mandolin, banjo, cavaquinho, charango, bouzouki, baritone, and more. Use it as a guitar tuner, a bass tuner, a violin tuner, or a ukulele tuner. The chromatic engine reads any pitch from the microphone, so it tunes any string instrument.

🎚️ SPECIAL TUNINGS

Pick a tuning and follow it string by string: Drop D, Drop C, Open G, Open D, DADGAD, half step down, and full step down, with presets for guitar, bass, ukulele, violin, mandolin, cavaquinho and more. Standard tuning is free on every instrument. The chromatic tuner still reads any pitch, so tunings beyond the presets work too.

⌚ A REAL WEAR OS TUNER

The watch app is a full chromatic guitar tuner on its own. It listens through the watch microphone, so you can tune without taking the phone out of your bag. Tune at the back of the stage, in a dressing room, or on the couch.
