FROM SONG TO CHORDS • Import a video or audio clip from Photos or Files and get a chord timeline and tab • Recognizes more extended chords (9, 11, 13) and names them the way players write them: Cm9, F13 • Listen to verify: every result is a draft you can check against the recording • Solo mode turns a single-note melody into suggested TAB positions • Import MusicXML, Guitar Pro (GP3, GP4, GP5, GPX, GP) or ChordPro files, or type the chords in

PRACTICE ON A REAL FRETBOARD • Chord shapes and notes move across a photo-real guitar neck in time • Chord diagrams sit above the scrolling tab and move with it • For imported songs, chord diagrams show shapes worked out from that song's own tab • Scale degrees on every chord show how the harmony moves • Focus mode: hide the controls, drag to any bar, or loop a single bar • Loop the whole song, a chord pair or a single chord, and slow the tempo down • Score practice: notation and tab in step, with a cursor that follows the music • Count-in and rhythm patterns keep time with you

PLAY IT AT YOUR LEVEL • Arrange the same song at Basic, Intermediate or R&B level, with a capo when it helps • Capo and transpose, or simplify every chord to plain triads and 7ths • Sing along: chords over the lyrics, your arranged guitar with the song's own drums, bass and vocals • Tone Studio: amp, cabinet, EQ and effects for the built-in guitar sound • Two guitars to choose from: Classical or Electric · Clean

KEEP PRACTICING • Practice log with a daily goal and a calendar of the days you played • Score memos you can pin to the chord you're on • Built-in tuner • Score library with folders, saved on your device and synced with iCloud when available • Export analyzed parts as Guitar Pro files
