Installing
What to expect the first time
macOS
The build is not notarised, so Gatekeeper will refuse it on first launch. Open System Settings → Privacy & Security and choose Open Anyway, or right-click the app and pick Open.
Windows
SmartScreen shows a blue warning because the installer is unsigned. Choose More info → Run anyway. The universal installer is much larger; take a per-architecture one unless it fails.
Linux
An AppImage needs the executable bit before it will run: chmod +x on the file, then launch it. The .deb and .rpm packages install normally through your package manager.
The builds are not code-signed yet. If your institution blocks unsigned applications, use the browser version; it needs no installation and runs the same simulator.

Nothing to install, and always the current build. Use Chrome or Edge at 1280×720 or larger.

All releases
Earlier versions, for classrooms that need to keep an existing setup unchanged.
The desktop app uses the same backend as the web app, so versus rounds work the same way. Solo practice needs no network. See the simulator for details about offline use.
