TunerToGo: Guitar & Bass Tuner

TunerToGo turns your Wear OS watch into a precise tuner – always on your wrist, ready the moment you pick up your instrument.

Tune fast and precisely
• Accurate pitch detection from 25 Hz (low B of a 5-string bass) up to 4.5 kHz
• A calm, readable display: the needle is smoothed, short slips are ignored, and the last note stays on screen for a moment after the string stops ringing
• The colour shows how far off you are – coral, amber, lime, then green when you hit the note
• A short vibration when a string is in tune, so you can keep your eyes on the pegs

Made for your instrument
• Instrument mode with automatic string detection
• Guitar: Standard, E♭ Standard, D Standard, Drop D, Drop C, DADGAD, Open D, Open G, Open E, Open C
• 7-string guitar, bass (4, 5 and 6 strings), ukulele (standard, low G, D tuning, baritone), violin, viola, cello, double bass, mandolin, banjo
• Turn the crown or bezel (or tap the dial) to lock the tuner onto one string – handy when a string is far off
• Tuned strings get a tick
• Chromatic mode for every other instrument and for your voice

For musicians
• Reference pitch from 400 to 480 Hz, e.g. 442 Hz for orchestras or 415 Hz for baroque music
• Transposition for B♭, E♭ and F instruments (trumpet, clarinet, saxophone, horn)
• Note names in English (B), German (H) or solfège (Do Re Mi), with sharps or flats
• Gauge or strobe display – the strobe stands still when you are in tune
• Reference tone to tune by ear on watches with a speaker
• Adjustable in-tune range and microphone sensitivity

Built for Wear OS
• Modern Material 3 design for round watches
• Tile to start tuning with one tap
• Works standalone, no phone app needed
• Keeps the screen on while you tune and lets it sleep again when you stop
