Chordleaf: Song Sheets

Keep a master song. Give every set its own voice. Chordleaf is an offline song folio for singers, songwriters and rehearsal leaders. Bring your own ChordPro text, arrange a vocal key for each set, and carry complete printable sheets and editable backups. READ THE SONG • Chords stay above their lyric anchors as long lines wrap. • Transpose common letter chords, extensions such as C6/9 and slash bass notes. • Choose accidentals, serif or monospaced reading, text size and a night sheet. • Jump between sections and edit the master source, title, artist, key and tempo. ARRANGE A SET • Order songs and keep a separate vocal key for each set. • Changing a set arrangement leaves the master reading key alone. • Export a set CSV with song order, key, transposition and tempo. TAKE THE WHOLE SHEET • Preview real paginated song and set PDFs, then Save or Share them. • Choose A4 or Letter paper and print font size. • Keep current .cho arrangements and exact original imported bytes. • Export a restorable JSON library or a ZIP of current sources, retained originals and set CSVs. • Restore backups as new copies with independent song and set references. PRIVATE BY DESIGN Your songs and sets stay on your device. No account, ads, subscription, analytics or cloud song service. The app does not request microphone, camera or broad storage access. Files you choose to save or share leave through Android's system controls. START WITH YOUR SONGS The library starts empty. You may choose three original example songs to try the workflow. Use only lyrics and music you have permission to use. SCOPE & LIMITS Chordleaf supports a conservative ChordPro text subset, not the full ChordPro specification. Unknown tokens and unsupported directives remain in the source and are identified in Source notes. A source transpose directive must be removed before exporting a current arrangement. There is no audio playback, recording, chord diagram, MIDI or online song catalog. Import UTF-8 .cho, .chordpro, .chopro, .pro or .txt up to 2 MB.

Reading/printing supports up to 120,000 characters and 2,400 lines per song; a set PDF supports up to 240 pages and one million lyric characters. Source ZIP content is limited to 128 MB. Generated files are temporary and clear on restart: use Save or Share to keep important exports. Uninstalling removes the private library. One paid download. All described features included.
