Guitar Tuner

Guitar Tuner for Wear OS turns your watch into a fast, accurate guitar tuner you always have with you. No phone, no cables, no clip-on — raise your wrist, play a string, and tune.

WHY A GUITAR TUNER ON YOUR WATCH
Your phone is in a bag or across the room. Your watch is already where your hands are. This tuner runs entirely on the watch, so tuning takes one gesture instead of five.

VIBRATION TELLS YOU WHEN YOU ARE IN TUNE
The watch taps your wrist with a distinctive double pulse the moment the string locks in, so you can keep your eyes on the fretboard. The screen floods green at the same time — easy to read from the corner of your eye, on a dark stage or in a bright room.

BUILT FOR A ROUND WATCH SCREEN
• Giant note name filling the display — readable at a glance
• Needle sweeping the top arc: amber when the string is flat, blue when sharp
• Arrows showing which way to turn the tuning peg
• Six string indicators showing which guitar string you are tuning
• Extra fine needle movement near the target, so the last cents stay visible
• Cents and frequency in Hz shown while tuning
• Always-on display support

GUITAR TUNINGS INCLUDED
• Standard tuning (E A D G B E)
• Drop D tuning
• Half step down (Eb standard)
• DADGAD
• Open D
• Open G

Rotate the crown or the bezel to change tuning instantly — no menus while you play.

ACOUSTIC AND ELECTRIC
The tuner listens through the watch microphone, so it tunes acoustic guitars, classical guitars and unplugged electric guitars alike.

OFFLINE GUITAR TUNER — WORKS ANYWHERE
No phone required. No pairing, no account, no sign-in, no internet. This app does not even request network permission, so the tuner works on a plane, in a rehearsal room with no signal, at a campfire, or anywhere your phone is not.

NO ADS, NO SUBSCRIPTIONS, NO TRACKING
Pay once, own it forever. No advertising, no analytics, no data collection. Audio is analysed live on your watch and is never recorded, stored or uploaded.

PERFECT FOR
• Guitarists who practise every day
• Players tuning between songs on stage
• Beginners learning to tune a guitar by ear
• Anyone tired of unlocking a phone just to tune one string

REQUIREMENTS
• Wear OS 6 or newer
• Microphone permission (used only for pitch detection while the app is open)
