Getting started

Two tabs along the bottom: Library (every song) and Playlists (set lists).
Tap + to add songs — New song, Import files…, or Import folder….
Tap any song to open the reading view; everything is saved per song.

Importing & exporting

Import files… — pick one or more .chordpro sheets. Plain-text chord-over-lyric sheets work too.
Import folder… — walks every subfolder, and can turn each subfolder into a playlist.
Re-importing matches existing songs instead of duplicating them.
Export… or Print… from a song's ⋮ menu, or multi-select in the library. Exports are plain ChordPro.

Reading & transposing

Reading controls (sliders icon): Transpose ±semitone, Capo, ♯ / ♭, font A− / A+, and 1–3 columns.
Fit to screen auto-sizes the song so the whole sheet fills the page; touch a size control to take over manually.
Auto-scroll: tap the floating play button; press and hold it to set the pace.
Fullscreen from the ⋮ menu. In a playlist, use the prev/next arrows or swipe between songs.

Browsing the library

Search across titles, artists, and lyrics — accent-insensitive, so plain letters match accented text.
Filter by Tags, Artists, or Keys; sort by title, date added, last edited, or last opened.
Star favourites and flip the list to starred-only.
Long-press to multi-select: add to playlist, export, print, or delete.
Three themes — Light, Paper, Dark.

Light theme — Light

Paper theme — Paper

Dark theme — Dark

Playlists

Open the Playlists tab and tap + to create one — or fold an imported folder into playlists.
Add songs from a song's ⋮ → Add to playlist…, or by multi-selecting in the library.
Drag to reorder; swipe a row to remove it (the song stays in your library).
Open the first song and step through the set with prev/next or a swipe.

Writing & editing

+ → New song, or a song's ⋮ → Edit ChordPro.
Plain ChordPro text with a live preview; toggle between ChordPro and Plain text input.
No save button — it auto-saves a moment after you stop typing.
