What separates a score keeper app from generic score tools
A real score keeper has to survive live match pressure. It should keep point entry simple when pace rises and still preserve context for deuce, tie-break, and server flow.
Generic score tools often fail because they track a number but not the actual match workflow. That gap creates correction loops and partner confusion.
- Test point-entry speed during a full game, not a single point demo.
- Verify that corrections can be done cleanly without losing match state.
- Check whether the app keeps service and side context visible through set transitions.
