YAGT

New: snappier meter, tongue-in-cheek tuning feedback, DADGAD. Two pitch detectors cross-check every frame. No ads, no subscriptions. Just a tuner.

YAGT is a guitar tuner and bass tuner for iPhone and iPad. Standard tuning, drop tunings, open tunings, alternate tunings, or build your own. Pluck a string, see exactly where you are, tune up.

DUAL-DETECTOR ACCURACY Two pitch detectors run in parallel and cross-check each other every frame — a neural network and a classical algorithm working together. The result is a meter that holds steady on wound low strings where most tuners flicker between the fundamental and its harmonics.

GUITAR AND BASS Full support for 6-string guitar and 4-string bass, with detector presets tuned for each. Bass fundamentals stay locked instead of jumping to the 2nd harmonic, even on the wound low strings most tuners flicker on.

SMART STRING DETECTION Auto-detect identifies which string you're playing and locks on. Tap any string to override manually. Tap again to return to auto. The tuner stays out of your way.

17 BUILT-IN TUNINGS PLUS YOUR OWN Guitar: Standard, Half Step Down, D Standard, Drop D, Double Drop D, Drop C#, Drop C, Drop B, Open G, Open D, Open E. Bass: Standard, Half Step Down, Full Step Down, C Standard, Drop D, Drop C. Need something else? Create your own custom tuning, name it, and edit it any time. Custom tunings sit alongside the presets and stick around between sessions.

LAG-FREE METER A smooth, responsive meter with cents readout shows exactly how sharp or flat you are. Color-coded green/yellow/red so you can read it at a glance — no chasing the needle.

REAL-TIME STABILITY GRAPH A live sparkline below the meter tracks your pitch over time. Watch yourself settle into tune and see how stable your string holds.

HAPTIC FEEDBACK A subtle tap when you hit the zone. Tune by feel without staring at the screen.

ADJUSTABLE REFERENCE PITCH Set A4 anywhere from 400–480 Hz to match pianos, recordings, or other instruments.

NOISE CALIBRATION One tap reads your room noise and sets the mic gate. Works in quiet rooms and noisy rehearsal spaces. If the room gets louder mid-session, the tuner notices and offers to recalibrate. Manual sensitivity slider for fine control.

CUSTOM BACKGROUNDS Choose a photo from your camera roll. Adjust opacity, pinch to zoom, drag to reposition. Lock it in place once you've got it framed so the meter can't be nudged mid-tune.

No ads. No subscriptions. No account. No internet. Just a tuner.
