Guitar Tuner listens through your microphone and shows exactly how far each string is from pitch, measured in cents. A scrolling pitch trail shows how the note moves over time, so you can watch a string settle after a pluck instead of guessing from a jumping needle. FEATURES • Automatic string detection, or pin one string and tune toward it • Readout in cents with a clear in-tune indicator • Scrolling pitch history so you can see the note settle • Alternate tunings: retune any string from -5 to +2 semitones, covering drop D, DADGAD, open G, open D, open E, half-step down and drop C • Standard tuning is equal temperament at A = 440 Hz, matching every mainstream tuner • Works entirely offline BUILT FOR REAL STRINGS A plucked string reads sharp for the first fraction of a second, because the pluck itself raises tension, and then drifts flat as it rings out. Guitar Tuner accounts for both, so the reading settles where the string actually settles rather than chasing the decay downward. PRIVACY Audio is analyzed on your device and never leaves it. Nothing is recorded, stored or transmitted.
