OpenChordBook

OpenChordBook reads and edits chord charts, with a full-screen sheet that leaves room for the music. Your library stays on your device. No account, ads, analytics or playback.

• Read charts offline and transpose without hiding the chords

• Write charts using ordinary chord names, with a live preview

• Use named sections, repeat bars and different time signatures

• Organize tunes in nested folders and choose a destination before importing

• Import iReal Pro HTML playlists or paste playlist links

• Export charts, selected tunes or a full folder to a playlist file

• Search your library and group different versions of the same tune

• Adjust chart size and switch between day and night themes

• Optionally download community playlists from Discover

Tunes are not packaged with the app; they are downloaded by the user. You do not need the iReal Pro app. Your library stays on your device, and you can export your tunes to keep a copy.
