What is a Desktop PWA?
Native Window
Runs in its own window without browser chrome — exactly like a native app. No address bar, no tabs.
Offline Capable
Core mission data, hospital directory, and active missions are cached locally. Works when your sim setup has spotty WiFi.

Always on the latest version. No app store, no installers, no waiting. Refresh to get new features instantly.
