Deuce Tennis Score

Deuce is the simplest way to score a tennis match on your Apple Watch.

Tap to score. Hold to undo, or pop the menu and tap Undo Last Point. The server's side of the screen glows so you always know whose turn it is. The numbers are big enough to read on a sweaty wrist between points.

Deuce speaks your language. Set your Apple Watch to Traditional or Simplified Chinese and the whole app follows: scoring, formats, history, live sharing.

Share Live — the scorer taps Share Live, a 6-character code appears, and anyone else with Deuce can mirror the scoreboard on their own watch or iPhone in real time. Singles, doubles, or just letting a friend follow along — no accounts, no setup.

On iPhone, Deuce is where the rest of your tennis lives. Tennis IQ explains the technical ideas that change how you play, the scoring rules, every match format, and the NTRP scale — in English, Traditional Chinese and Simplified Chinese. Events runs a whole club tournament from the phone: paste a roster, generate a draw that keeps same-school players apart, score courtside, rank the field, draft teams, build doubles lineups, and share the order of play. Gear keeps track of your rackets, strings and grips.

Playing a quick 1-set match? Pick "1 set" on the New Match screen and the match ends the moment the set is won — no taps required. Or play best of 3 the traditional way.

Under the hood, every point is event-sourced and timestamped — undo always works, the score is exactly right, your match is autosaved after every point, and the iPhone app shows per-point pace stats.

Playing for fun? Pick No-ad scoring and the deciding point wins the game — no more endless deuces.

No accounts. No ads. No tracking. Just a scoreboard that gets out of your way.
