OneTune: Instrument Tuner

About this app

Tune, keep time, and practice from your own scores. OneTune brings an offline instrument tuner, metronome, score library, and beginner knowledge references together on iPhone and iPad. Choose from 49 instrument and tuning presets plus Universal Tuning (chromatic mode), covering guitar, ukulele, bass, bowed strings, mandolin, banjo, Chinese strings, and transposing wind instruments. Read pitch, frequency, and cents on a clear visual gauge. Select a target string to begin listening immediately; reference tones play only when you request them. Practice with a 30–240 BPM metronome, tap tempo, four time signatures, quarter-note, eighth-note, triplet, and sixteenth-note subdivisions, and an optional first-beat accent. Open the Knowledge tab for 24 guitar and ukulele chord diagrams, 120 scale combinations across 12 roots and five scale families, and 15 illustrated beginner lessons. Explore strings and finger placement, tuning, notes and cents, time signatures, rhythm, tablature, and concert versus written pitch. Chord and scale diagrams support right-handed and left-handed views, with offline audio previews. Import PDF scores or score photos into your local library. Organize and favor
