Before the current SwiftUI rewrite, Calíope was a cross-platform desktop app written in Qt for Windows, Linux and macOS. Those builds are kept available here for people who still depend on them, but they are no longer maintained: no bug fixes, no security updates and no user support. The source code is below, under its GPL licence. New development happens exclusively on the native Mac, iPad and iPhone app you can find on the App Store.

The Qt Calíope is free software under the GNU GPL, version 3 or later, and the builds on this page are distributed under that licence. Publishing the source is therefore not a courtesy: it is what the licence requires, and this package is that source. It corresponds to the 20251201 builds (macOS on Qt 6.10.0, Linux and Windows on Qt 6.10.1) and contains the full licence text in LICENSE, the notices for the MariaDB Connector/C headers it includes, and a short README on how it was built. It is published as a historical archive: it is not maintained, it receives no fixes, and nobody answers questions about it.

Why the rewrite? The Qt version was a solid cross-platform baseline, but it could not integrate with the pieces that make the Apple ecosystem special: SwiftUI, widgets on the desktop and Home Screen, AppIntents for Siri, Keychain, iCloud sync, native SwiftNIO SSH. The Mac, iPad and iPhone app you see on the front page is a full rewrite built specifically for those platforms — and it is where every future feature will land.
