What a scoreboard app must do in live play
A scoreboard app is not just a counter with bigger text. It has to preserve shared trust when four players and sometimes spectators are all checking the same score state.
That means readable display, clear server-side context, and fast correction flow matter more than extra dashboards during match time.
- Check score readability from baseline distance, not only in hand.
- Confirm that side and server context stay visible through game transitions.
- Test one-step correction during deuce pressure before committing.
