Your song repertoire, offline

What Chordbook does

Chordbook is the offline repertoire manager every guitarist has wanted but never found. Save songs with their chord charts, organized into labeled sections (Intro, Verse, Chorus, Bridge), then let the built-in transpose stepper shift every chord up or down by semitone so you can match any singer or capo position in seconds. Mark songs as “learning” or “known” to stay honest about your real repertoire.

Build setlists for gigs, open mics, or practice sessions and pull them up on stage with a tap. A quick-reference chord chart covers the shapes you always forget. Everything runs on SwiftData with zero network calls.

• Song library with key, capo, and labeled chord sections • Instant semitone transpose that rewrites every chord live • Learning / Known status filter to see your true repertoire • Setlists with drag-to-reorder • Built-in chord reference for common shapes • No account, no cloud, no ads

What's inside

• Song repertoire — Create songs with title, artist, key, capo, and any number of labeled chord sections. Filter the list by Learning or Known status.
• Live transpose — A semitone stepper on the song detail screen rewrites every chord in all sections instantly, with capo suggestion displayed alongside.
• Setlists — Create named setlists, drag songs into order, and display them full-screen for gig or practice use.
• Chord reference — A built-in chart of common open and barre chord shapes, searchable by chord name, available offline.

Why we built it

Guitarists maintain their song repertoire across scattered notes apps, camera-roll photos of chord sheets, and napkins — with no way to transpose chords on the fly, track what they actually know, or build a clean setlist without scrolling through chaos.

What makes it different

Chordbook is the only offline-first, SwiftData repertoire app that combines freeform chord-section editing with a live semitone transpose engine, a learning/known status layer, and drag-reorder setlists — without requiring an account, cloud sync, or subscription to use any core feature.

Who it's for

Built for anyone who values fast, private, on-device software with a calm, focused UX.
