Compose on desktop. Access everywhere.

Yes — the desktop app is free to download and use. You get all core notation features, unlimited local file storage, and PDF/audio export at no cost. No account required to get started.

No. You can download and start composing immediately without an account. You'll need a Flat account to sync your library across devices or access your existing scores.

Flat Power is Flat's premium subscription ($9.99/month or $49.99/year). It unlocks cloud sync across desktop, web, and mobile, real-time collaboration, version history, advanced notation features, and the full instrument library. If you only compose on one device and don't need collaboration, the free tier covers you.

No. Desktop is included in your existing Flat Power subscription. Just download the app and sign in with your Flat account — your full library will be there.

Yes. You can compose, edit, and play back scores without an internet connection. Sync with your cloud library happens automatically when you're back online (Flat Power required for sync).

The desktop app is available for both macOS and Windows.

MuseScore is free and powerful but desktop-only, with no collaboration and a steep learning curve. Dorico is professional-grade but costs $700+ and locks you to one machine. Flat gives you professional notation, real-time collaboration, and the only cross-device sync in the category — at $49.99/year, on every device you own.

Yes. Flat supports MusicXML and MIDI import, so you can bring in scores from MuseScore, Sibelius, Dorico, Finale, or any other notation tool that exports those formats.

Yes. All scores saved locally on your device remain yours. If you cancel Flat Power, you lose cloud sync and collaboration features, but your local files are unaffected.
