Tune monophonic instruments in seconds. OneTune pairs a visual cents gauge with original instrument artwork, string targets, frequency, and clear pitch feedback. Play a reference tone for any tuning string, then return directly to microphone listening.
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, quarter-note through sixteenth-note subdivisions, and an optional first-beat accent.
The music library includes 24 essential guitar and ukulele chord diagrams plus 120 common scales across 12 roots and five scale families. Review note sequences and fretboard positions, switch every diagram between right-handed and left-handed display, and hear complete chord and scale previews offline. Six short lessons cover beginner music fundamentals.
Chromatic, standard guitar, standard ukulele, and concert-pitch wind tuning stay free. Choose a yearly Pro subscription or a one-time lifetime purchase to unlock 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.
