Guitar Tuner: Chromatic+

Tune guitar, bass, violin and ukulele in seconds. The chromatic needle shows the note and how many cents you are off, with an adjustable A4 reference.

Guitar Tuner: Chromatic is a fast, accurate tuner for guitar first — then bass, violin, ukulele and every other pitched instrument. Play a string and watch the needle settle on the note and cents.

• Real-time mic pitch detection, accurate to the cent • Guitar tunings: Standard EADGBE, Drop D, Open G, DADGAD • Presets for bass, violin, ukulele, mandolin, banjo and full chromatic • String auto-advance walks you through each open string • Smooth cents needle that's easy to read on stage • 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 Guitar, play the low E and let auto-advance walk you down the neck — you never have to tap between strings. Switch Drop D or DADGAD when the song needs it. Set A4 if your ensemble tunes off 440 Hz, or transpose when you are capoed. For ear training, hold the reference drone and match it; the stability meter shows whether you are holding the pitch or drifting.

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