A tiny desktop overlay that floats over your other windows — check your status, gold and events, fly out and trade at stations, and get notified the moment you dock, all without opening the full game.
Direct APK: your phone may warn about installing from outside the Play Store — allow it for this download. Doesn't auto-update; check back here for new versions.
Open the app and sign in with your email and a Companion Code. Generate your code under Settings → Desktop Companion. The code is app-specific — it isn't your account password, so it's safe on your desktop and works even if you sign in with Google or Apple. Updates install themselves from inside the app.
