Your songbook, on every screen you own.

Campfire is a chord sheet viewer and editor built around the plain-text ChordPro format. It runs natively on Android, iOS, macOS, Windows, Linux and the web.

The interface is designed around practical use, whether you’re organizing a song library, building setlists, or playing a gig. Songs automatically adapt with multi-column layouts and customizable section ordering to make reading easier on stage. It also includes on-the-fly transposition, adjustable font sizing, a lyrics-only view for singers, customizable themes, and a Performance mode to lock the app against accidental edits. Songs and setlists can be exported as printable PDFs, with a page preview, song selection, and saved paper, sizing and content options.

The app works offline (the web app after its first visit), requires no account, and doesn't rely on a central server. Syncing the library across devices is handled directly through your own Dropbox storage. Campfire is free, open-source, and has no ads or tracking. Check out the Privacy Policy for more information.

Under the hood

Campfire is a Kotlin Multiplatform project targeting Android, iOS, desktop (JVM) and the web (Kotlin/Wasm). The whole interface is written once with Compose Multiplatform and Material 3 Expressive, with navigation handled by Navigation 3 and dependencies wired together at compile time using Koin Annotations. Platform-specific code is limited to thin shells: file pickers, system bars, share and "open with" intents, and the storage behind the library, which is a plain folder on Android, iOS and desktop and the Origin Private File System in the browser.

The code is split into small modules with a strict api / implementation boundary at every layer: a presentation module with the screens and the ViewModel, a domain layer of single-method use cases, repositories on top of local and remote data sources, and the app modules that hold each platform's entry point. The ChordPro parser, transposer and serializer live in a dependency-free chordpro module, so the format logic can be tested and reused independently of any UI or storage.

Everything the app owns is a plain file: songs are .cho files and setlists are small JSON documents, so nothing is locked inside a database. Syncing is a pure planning step over file hashes and a remote listing, run against a provider interface that Dropbox implements through OAuth with PKCE, which is why no backend of Campfire's own is needed.
