Friend battle rooms: create a room and compete with friends using an invite code. Random matchmaking unlocks once we reach 100 registered users — you can see the progress on the room screen. Minor fixes.

• Invite messages now include a gymsetai.com/join link. On iPhone, tapping it opens the app with the invite. • Friend battles now change days in the creator's phone time zone instead of always Taipei time. Random 1v1 only pairs players within 3 hours of each other. • When a newer version is on the App Store, the app now lets you know so you can update. • Deleting your account no longer deletes group rooms that haven't started: you leave the room, and if you were the host, hosting passes to the member who joined earliest.

• New home screen: a model of your body you can rotate and zoom, with every muscle colored by the level your workouts have earned it. Tap a muscle to see its level over time and exercises that train it. • Share cards: turn a finished workout, a level-up, your 30-day change, a monthly recap, a battle win or your place in a room into an image and share it from the iOS share sheet. • Group battles: new Team battles (2v2, 3v3, 5v5) and Ranking rooms (3–10 players), started with an invite code or by random match. • Ranks: random 1v1 matches, team battles and ranking rooms count toward your rank; your first 2 ranked battles are placement. Battles with friends stay unranked. • Sign in with Apple or Google; email accounts still work. Optional "Sync to Apple Health" (off by default), and you can import cardio from Apple Health during a workout. • Now available in English, 繁體中文, 简体中文, 日本語, 한국어 and Español. Change it in Profile > Language. • Short tutorials the first time you open each tab (Home, Train, Battles, History, Profile) and the workout screen. Replay any of them from the new "How to use" page in Profile. • Many fixes.
