Tennis IQ is now somewhere to read, not just a list. • Ten technical ideas that actually change how you play, each with a cue you can use in your next game. • The scoring rules, one question at a time: deuce, love, tiebreaks, doubles, and no-ad versus ad scoring. • Every match format, with roughly how long it takes and when to use it. • The NTRP scale, 1.0 to 7.0, and the tiers a club ladder groups it into. All of it reads in English, 繁體中文 or 简体中文. Tap the globe, or set it once in Settings. Events grew up. You can run a whole club event from your phone: • Paste the roster from the group chat. The draw keeps same-school and same-club players apart where it can. • Score courtside. Standings rank the field on win rate, then point differential, then strength of schedule. • Draft teams in snake or alternating order, with an undo for the mistap. • Build doubles lineups by tapping a player and then a seat, with live validation so nobody is booked on two courts at once. • Share the order of play as text, straight back into the group chat. • Export an event to a file to move it to another phone. The watch is unchanged: one tap per point, hold to undo.

Deuce now speaks Chinese — Traditional and Simplified. • Set your Apple Watch to 中文 (Traditional or Simplified) and the whole app follows: scoring, formats, history, and live sharing. • Tennis terms use natural local wording. Everything from 2.3 is still here, including Share Live — the scorer taps Share Live, a 6-character code appears, and anyone with Deuce mirrors your scoreboard in real time on their watch or iPhone.

Share Live — the headline feature: • The scorer pops the menu and taps Share Live. A 6-character code appears. • Anyone else with Deuce — singles partner, doubles teammates, a friend watching from the bench — enters the code on their watch (Live tab) or iPhone (Watch a Live Match on the Dashboard). • Everyone sees the same scoreboard updating in real time: server glow, big point digits, set scores, who's leading. • Codes expire after six hours. No accounts, no setup. Plus the stuff that landed since 2.0: • 1-set matches — pick "1 set" on New Match; ends the moment the set is won. • No-ad scoring — at deuce, deciding point wins. • Bigger set scores. Undo Last Point in the menu. • End Match → Completed works right now: trophy if you're ahead, neutral "Match Ended" if not. • Per-point pace stats on iPhone — total time, avg per point, longest, shortest. • Notes + editable opponent on iPhone history.

A bigger update than usual: • 1-set matches. Pick "1 set" on the New Match screen — the match ends the moment the set is won. Most casual play is one set; now the app knows it. • Bigger set scores at the top of the scoring screen. Easier to read mid-rally. • Undo Last Point added to the menu. The hold-to-undo gesture still works. • No-ad scoring. At deuce, the deciding point wins the game. • End Match → Completed works better. If you ended ahead in sets the trophy still shows. If you ended with no winner it's a neutral "Match Ended" — no false celebration. • Per-point pace. Every point is timestamped. The iPhone app shows total match time, average per point, longest and shortest point. • Notes + editable opponent on iPhone. After the match syncs, rename players away from "You"/"Opponent" and add notes — who you played, what court, how it went. Future-you will thank you. Your existing matches carry over.

Three small things from playing with 2.0: • Bigger set scores at the top of the scoring screen. Easier to read mid-rally without squinting. • Undo Last Point added to the menu. The hold-to-undo gesture still works — the menu's there for when your thumb won't cooperate. • No-ad scoring. New option on the New Match screen. At deuce, the next point wins the game — faster matches when you're playing for fun. Your existing matches carry over.

Welcome to Deuce 2.0 — a complete redesign. • Tap to score, hold to undo. Two big zones, no fumbling. The server's side glows so you always know whose turn it is. • A new look. Deeper black, brighter lime, every numeral easy to read on a sweaty wrist. • A new name and logo. Hi, we're Deuce. • A trophy moment when you win. • A cleaner history with per-set bar charts. Your existing matches carry over.
