## What is OneTune?

Tune monophonic instruments in seconds. OneTune pairs a visual cents gauge with original instrument artwork, string targets, frequency, and clear tune-up / tune-down guidance.

Choose from 24 practical presets for guitar, ukulele, bass, bowed strings, mandolin, banjo, Chinese strings, and transposing wind instruments. Then keep practicing with a 30–240 BPM metronome, tap tempo, four time signatures, 24 essential guitar and ukulele chord diagrams, and six short beginner lessons.

Chromatic, standard guitar, standard ukulele, and concert-pitch wind tuning stay free. Pro Lifetime is a one-time purchase that unlocks the full preset library, adjustable A4 reference pitch, and precision confidence controls.

OneTune works offline. Audio is analyzed in memory on your device, is never recorded, and is never uploaded. No account, ads, or third-party tracking.
