Frequently asked questions about mobile version

What devices does it work on?

Android from version 7.0 (Nougat and newer), iOS from version 13. This covers practically all smartphones of the last 6 years. iPad and Android tablets also supported.

Do I need fast internet?

No. Game is asynchronous, little data transferred (fleets, builds, stats). Works on 3G/4G without issues. Wi-Fi needed only for initial download.

Is progress on phone and PC one game?

Yes, one account. Opened from phone, continued from browser, then from another phone — same progress everywhere. Sync is automatic, in cloud.

Are push notifications annoying?

They're optional and granular. Enable only important ones — attacks on your planet, alliance reply, chat pings. Everything extra can be disabled in settings.

Can I play in airplane mode?

No — it's MMO, requires connection for sync. But if you came out of subway / elevator / tunnel — the game catches up automatically. Graphics stored locally, not downloaded each time.

Is there advertising in the app?

No. The mobile app is completely free and ad-free. No banners, no "watch for reward" videos. Premium subscription is optional.
