OneTune now uses the Chinese name “知音”. Tuning, metronome, chords, and scales work as before.

Choose yearly or lifetime Pro access. Existing lifetime purchases remain active, and eligible subscription offer codes can be redeemed in the app. The App Store page also adds Traditional Chinese text and screenshots.

Pitch tracking now stays steadier while plucked notes decay and rejects common octave-harmonic jumps more reliably. The Chords tab is now a Music Library with 120 common guitar and ukulele scales across 12 roots and five scale families. Each scale includes its note sequence and a 12-fret map. Complete chord and scale audio previews now work offline, and all chord diagrams and scale fretboards can switch between right-handed and left-handed display.

Low G ukulele tuning now stays aligned with the intended string and handles common octave-harmonic readings more reliably. The in-tune range is more practical and stable, so pitches within ±5 cents turn green without flickering around the boundary. String presets no longer mark unrelated chromatic notes as in tune, and long string sets such as guzheng now support focusing an individual string. Focused-string guidance is also simpler, without peg-turn direction text.

Reference tones are now available from the tuner, with microphone listening resuming automatically after playback. The metronome now supports quarter-note, eighth-note, triplet, and sixteenth-note subdivisions, plus an optional first-beat accent. This update also fixes metronome audio reliability and improves audio-session recovery when switching between tuning and practice.
