Songs are stored in an open, portable format — readable in any text editor and shareable with any musician. Organise your library with custom categories, mark favourites, and search instantly by title, artist, or composer. ACCURATE CHORD DISPLAY Chords sit precisely above the right syllable using monospaced rendering — just like a printed chart. Switch between guitar and piano chord diagrams and transpose to any key. BUILT FOR PERFORMANCE - Auto-Scroll: Hands-free scrolling at a configurable speed — set a global default or override per song. - Metronome: Built-in click with BPM, time signature, and auto-start. Tempo can be embedded directly in your ChordPro files. - Nashville Number System: Display chords as scale degrees for ensemble playing and transposition-agnostic charts. - Apple Music Integration: Link any song to a track in your Apple Music library for practice alongside the recording. CHORD LIBRARY Browse thousands of guitar and piano chords, filtered by key. The key browser shows all diatonic chords in any major or minor key. Hear any voicing played back with configurable arpeggiation. Save favourites for quick reference and learning, or just create your own custom chords. BUILD SETLISTS Organise songs into playlists for gigs or practice sessions. Reorder songs with a drag, add songs to multiple setlists, and step through them in order on the night. EXPORT YOUR WAY - PDF: Formatted charts with optional chord diagrams — ready to print or share. - ChordPro: Export with your current transposition baked in. - Plain Text or Lyrics Only: Simplified formats for sharing with non-musicians. - Batch Export: Export an entire playlist or category as a ZIP archive with customisable filenames. BACKUP & RESTORE Back up your entire library — or just selected songs, categories, and playlists — to any cloud service connected to the Files app. Restore selectively, so you never overwrite something you want to keep. DESIGNED FOR EVERY DEVICE GTK-Songbook scales beautifully from an iPhone 13 to the 13-inch iPad Pro. Fonts, icons, spacing, and diagrams all adapt so the app looks and feels right on your device. Perfect for guitarists, pianists, singers, singer-songwriters, teachers, or amateur strummers - anyone who performs from chord charts.
