About this app

Tune your guitar in seconds. Play a string, watch the needle, turn the peg until it goes green. That's it.

Guitar Tuner listens through your phone's microphone and shows exactly how far each string is from its note, in cents, with a clear needle and colours you can read at a glance: green is in tune, amber is close, red is far off.

TUNE ANY GUITAR
• Acoustic, electric and classical guitar
• Auto mode detects which string you are playing, no tapping needed
• Or tap a string on the headstock to tune it by hand
