Fretone is a practice companion for guitar — six focused tools, no subscription, no streaks or badges nagging you to keep a habit alive. Just the instruments you actually reach for between practice sessions. CHORDS — CHORD LIBRARY Every common chord — majors, minors, sevenths, sus2/sus4, add9 — with real, hand-verified fingerings, not algorithmically nearest-fret guesses. Browse by key, see a chord's family and the chords commonly played alongside it, and switch between alternate fretboard positions for the same chord. DRILLS — FRETBOARD EXPLORER Explore the fretboard note by note, or drill chord changes against a real strum pattern (down-up, pop-rock, reggae skank, and more) at your own tempo. METRONOME A clean, accurate metronome with every time signature you'd actually use, swing subdivisions, and a tempo that's remembered the next time you open it. FINGERSTYLE — FINGERSTYLE TRAINER Learn and practice fingerstyle patterns with a hand diagram that shows exactly which finger plucks which string, in real time. Build your own patterns in the custom editor, chain several chords into a full fingerpicking sequence, or start from patterns you already know. REFERENCE — FRETBOARD REFERENCE Pick a note, a scale, a CAGED shape, or a key on the circle of fifths, and see every place it lives across the whole neck light up at once — pentatonic and full scales, all seven modes, triads, and seventh chords, tap any fret to hear it. The lookup a player actually reaches for mid-practice, not a quiz. TUNER Real-time pitch detection powered by an on-device neural pitch model, with a steady needle, per-string tuned marks, and a glow when every string is done. Works with 6- and 12-string guitars, bass, and ukulele. Works for any tuning your instrument uses, with a capo control that shifts what counts as "in tune" without changing which string you're touching. No accounts. No ads. No streaks. Just an instrument's worth of tools, built by a guitarist who wanted them to exist. ## Key features - Real-time pitch detection tuner - Accurate metronome with various time signatures - Chord library with verified fingerings - Fingerstyle pattern trainer - Fretboard note identification trainer - Accurate song riff transcriptions ## Is Fretone safe?
