When is ChessUp launching?
Soon. ChessUp is in final review on both the App Store and Google Play · email support@olib.ai to be notified when it lands on either platform.
Does ChessUp require an account?
No. There is no sign-up, no email, and no profile. You open the app and you are in.
How does the engine work without internet?
The engine is a native Rust binary compiled into the app. It runs entirely on your device · positions and analyses never touch a server.
How does local multiplayer work?
ChessUp uses encrypted peer-to-peer connections via the open-source ConnectionPool library from StealthOS. Peers connect directly over the local network · no matchmaker, no game server.
Will Pro auto-renew?
Yes, like every App Store or Google Play subscription. You can cancel any time from Subscriptions on your device.
