Kanade is a precision guitar tuner with the soul of a vintage instrument — an ivory analog dial, a lacquer-red needle, and tuning accuracy you can trust to a fraction of a cent. Open the app and play. Kanade listens instantly, finds the string you're tuning, and guides you in: tune up, tune down, in tune. Hold the note and the string locks with a soft chime. Tune all six and the whole dial celebrates.
