Padel Score Counter is most likely the most feature-rich App on the App Store for tracking Padel Scores.
Requirement: Apple Watch.

With Padel Score Counter you can:

- See the serving order for each set, tie-break, and match tie-break. You can also reorder the serve order according in the beginning of each set according to the rules.

- Enter player names for both double and single matches. You can do this on your Apple Watch or iPhone before the match starts.

- Choose the match length (best of 3 or 5 sets) and the scoring method (every point or games only). The app supports no-AD scoring, also known as golden point, where the game is decided by the point after 40-40.

- Pause and resume the match at any time (due to rain etc.), or stop it before it’s finished (in case of injuries etc).

- Record your pulse, energy, and match time for saving in the Activities and Fitness apps.

- Use the iPhone companion app to view your previous matches and set up matches in advance for playing on your Apple Watch.
