Matsu: BJJ Athlete

Connected to your coach's academy. Track belts, plan techniques, shop gym merch, and get AI help with your game.

Matsu: BJJ Athlete connects you to your gym. Your coach runs Matsu: BJJ Coach on their end — you see the schedule, competitions, events, and merch store they've set up. No group chats, no screenshots of timetables, no guessing what time open mat is. Beyond the gym connection, Matsu is your personal training tool. Build technique flowcharts, write session notes, track belt progression, log weight and diet, set goals. The AI assistant knows BJJ. Ask it for technique advice ("what are good escapes from bottom side control"), have it build a training plan for your next competition, or ask it to log your weight for the day. It creates notes, flowcharts, diet entries — anything you'd normally type out by hand. Gym Connection Your coach's schedule, events, competitions, and merch store show up automatically once you join your academy. They update something, you see it. Technique Notes & Flowcharts Write notes after class while the details are fresh. Build flowcharts that map your game: if they do X, I do Y. Chain techniques into sequences so you can review them before your next roll. Belt & Stripe Tracking Every promotion logged. See where you started and where you are. White through black, every stripe along the way. Weight & Diet Log daily weight, meals, and set targets. Useful if you're cutting for a competition or just trying to stay consistent with nutrition. Merch Store Buy gis, rashguards, and gear from your gym's store inside the app. Your coach stocks the inventory, you browse and order. AI Assistant Ask it about technique, have it draft a comp prep plan, or just tell it to log today's training. Accepts text and voice. Every action it takes is logged, and you can undo anything. Statistics Training frequency, attendance, weight trends, diet tracking, competition history. All your data, easy to read. Works Offline Everything works without a connection. Syncs when you're back online. Available in English, Ukrainian, Russian, and Greek.
