goodMatches vs Doubles Round Robin Board

goodMatches is a smart, rating-based matchup rotation generator for social sessions of racket sports, tennis, badminton, table tennis, pickleball etc. With 5-20 players, goodMatches creates a sequence of balanced matchups, a.k.a 'goodMatches', ensuring the best balance possible by player ratings, which update automatically as results come in. While initial levels may be given by the organiser, the ratings, based on real results, will reflect the true skills of the players. Strengths of goodMatches: -- Easy sharing of group data: joining or inviting to an existing group is easy as it gets. New players are instantly part of your group with an invite code or user ID. -- Motivating rating feedback: rating growths are shown after every match. At the end of a session the rating changes for the day is displayed. Great for encouraging for developing players! -- Supports doubles AND singles: including sessions that mix both. -- Fair resting rotation: when a few players must sit out, goodMatches ensures fairness by rotating sit-outs evenly and alternately. -- Flexible mid-session changes: add or remove players when someone arrives late or leaves early, and fairness is still maintained. Try it out, and free yourself from the hassle or imbalance of manual, organiser-based social sessions!

Build a doubles round robin where the rests are fair, and where the rests are visible. NO ONE SITS OUT TWICE IN A ROW From the number of players and the number of courts, the app builds each round so that games played and rests stay even. Whoever sat out is put back on court next round. WHEN IT CANNOT BE KEPT, IT SAYS SO FIRST If there are too many players for the courts you have, the app tells you before it prints anything: someone will have to sit out twice in a row. It never hands you an unfair sheet in silence. It also tells you how many courts would make it fair. YOU CAN SEE WHO HAS RESTED A standings screen lists games played and rests for every player, so the next person to sit out is obvious to everyone. READABLE FROM ACROSS THE GYM Court numbers and names are drawn as large as the screen allows. Stand an iPad up on the bench and players can read it from the court. PEOPLE WHO ARRIVE LATE OR LEAVE EARLY Members can step out and come back without being deleted from the list. The gap that opened while they were away is closed after they return.
