Keep Score Tennis
Read full descriptionHide full description
Do you play tennis regularly but never write down the score? Are you curious what your rating would be if you tracked all your games? Keep Score is for the 99% of players who love to play and just want to know if they're getting better. Install the app and start logging matches immediately. See your win/loss record and a complete history of every match you've played. When you're ready to build a skill rating, sign in and share a 4-letter code with your partners and opponents. Once everyone joins your match and the score is recorded, your rating starts taking shape. Every completed set is rated on its own, so a set won off a stronger opponent moves your number even in a match you lost. The more you play, the truer the number. No public profiles. No leaderboards. Your rating is yours. Want to know exactly how ratings are calculated? Visit keepscore-tennis.pages.dev/ratings
