About Guitar Tuner
Guitar Tuner opens already listening. Pluck a string and the note name and needle are moving before you touch anything.
TUNE FAST
• Big note name, a needle from −50 to +50 cents
• Turns green and taps when you are within five cents
• Picks the nearest string by itself, or choose one of the six
• Responds in under a tenth of a second
ACCURATE
Pitch is detected on your phone from the microphone — no internet, no account. Reference pitch adjustable around A4 = 440 Hz (Pro).
MORE THAN STANDARD
• Standard, Drop D and half-step down free — five switches a day
• Open G, DADGAD, Open D, ukulele and four-string bass with Pro
• Chromatic mode for anything else
• Reference tones you can play back
ONE PERMISSION
The microphone, only while the app is open. Audio is never recorded or stored.
Remove ads with a one-time purchase, or go Pro for every tuning, unlimited switching, custom tunings, precision mode, reference pitch and accent colours.
Pro: no ads, unlimited use, all features unlocked. One-time purchase.
