The tennis score app for your Apple Watch
You know the rally you just won. You might not know whether that made it 30-15 or 15-30. Countoo does, and it sits on your wrist.
Free to download. Scoring needs a subscription after the free trial.
Score tennis without stopping
Open Countoo on your Apple Watch, start a tennis match and choose singles or doubles. After each point, tap the side that won it. The watch handles 15, 30 and 40, then deuce and advantage. When a game ends, it adds the game and hands the serve to the other side.
A set goes to six games with a two-game lead, with a tiebreak at 6-6. During the tiebreak, the watch counts in plain numbers to 7 with a two-point lead and rotates the server for you, so you can stop counting on your fingers at the change of ends.
Fix mistakes in one tap
It's easy to tap the wrong side when you're out of breath. The undo button takes back the last point, including whatever it changed, such as a game. The score goes back to exactly where it was, and you can carry on.
A record of every match
Countoo records your match as a workout through Apple Health. You can see your heart rate and calories during play, then review the result, time and effort on your iPhone. Over time, your wins, losses and most-played sport build up in one place, alongside any other sports you play.
Your match and health data is stored on your iPhone and Apple Watch, so your results stay with you. You need an iPhone on iOS 17 or later and an Apple Watch on watchOS 10.6 or later. Countoo is free to download. Scoring on the watch needs a subscription, which starts with a free trial.
