Each tap stores its real-world timestamp. The game clock is calculated from this start time.
In landscape, swipe upward on the clock or a gap between buttons to collapse Safari’s bars. The recorder stays in view. You can also use Safari’s page menu → More → Hide Toolbar.
For no address bar or tabs, use Safari’s Share → Add to Home Screen. Turn on Open as Web App if offered, then open GRU Score from its Home Screen icon.
Synced data is in the server’s SQLite database. Unsynced taps stay on this phone and retry when the connection returns. JSON exports include any queued changes.
Try every scoring control. Events stay on this phone and never reach the server or Google Sheet.
Your pending change is still saved on this phone.
