Round Robin Arena

Round Robin Arena generates the complete schedule for a round-robin tournament for any number of participants, correctly handling both even and odd numbers (with a bye round). Scores are entered courtside as the tournament progresses: the standings are automatically updated with each result, and at the conclusion, the app declares the winner. It is designed mobile-first precisely because the typical use is with a phone in hand during the tournament, and it can be installed as a PWA.
