Chartbook, a setlist and chord chart app for gigging musicians, is on the App Store

TLDR Chartbook is live on the App Store. Chord charts and setlists for musicians who actually gig, with autoscroll, foot pedal page turns and correct transposition. One payment, no subscription, and your whole library exports to plain ChordPro files.

Chartbook is on the App Store, a one-time US$19.99, for iPhone and iPad.

What it does

It reads well in a dark venue. Very large, high contrast type on black, autoscroll with a per-song speed that any drag overrides, the screen kept awake for the whole set, and one tap to hide every control.

Hands stay on the instrument. Bluetooth foot pedals pair as keyboards, so page turns happen with a foot rather than a hand off the fretboard.

Transposition that spells chords properly. Move a song up or down and E flat gives you A flat, never G sharp. Slash chords move both halves. Nashville numbers toggle on and off live.

Sets, not just songs. Build a running order from your library, drag to reorder, and see the total running time so you know whether you fill the slot.

PDF charts too. Import them and read them on the same stage screen with the same autoscroll and pedal, inverted so a white page does not blind you between songs. A PDF cannot be transposed, and the app says so instead of pretending otherwise.

Two promises the competition broke

Buy it once. No subscription, no weekly billing, no lifetime tier you have to buy to escape a subscription. The apps that gigging musicians already use moved to rent, and their users are still angry about it.

Your songs are files, not our database. One tap exports the entire library to a standard ChordPro file that opens in any text editor. Another app in this category lost people's libraries in a schema change; nothing here is locked in, so a bad update cannot take your songbook with it.

It works with no network at all, because venue wifi cannot be trusted, and it ships with no song catalogue. You bring your own charts, exactly as you would with a paper folder.

Get it on the App Store.
