Chromatic Tuner: Guitar

New alternate tunings — Drop D, Open G, DADGAD and more — plus a tappable chord diagram library for ukulele, banjo and mandolin. Tune and learn chords.

Chromatic Tuner is a fast, accurate, beautifully simple tuner for every instrument. Just play a note and watch the needle settle.

• Real-time mic pitch detection, accurate to the cent • Presets for guitar, bass, violin, ukulele and full chromatic • String auto-advance walks you through each string • Smooth cents needle gauge that's easy to read • A4 calibration (set your reference Hz) • Transpose for capo and alternate tunings • Auto and manual lock modes • Sustained reference drone to tune by ear • Pitch-stability meter so you hold the note steady

HOW YOU'D USE IT Pick your instrument preset, play an open string and let auto-advance walk you down the neck — you never have to tap between strings. Set A4 if your ensemble tunes to something other than 440 Hz, or dial in transpose when you are capoed. For ear training, hold the reference drone and match it by voice or bow; the stability meter shows whether you are actually holding the pitch or drifting.

Works for guitar, bass, violin, cello, viola, ukulele, mandolin, banjo and anything else with a pitch.
