Matsu: BJJ Coach

Run your whole gym from one app — classes, payments, competitors, team merch. Ask the built-in AI anything. New: phone number sign-in.

Matsu is the all-in-one app for BJJ and grappling coaches who run their own academy. Schedule classes, track every athlete, collect payments, prep competitors and sell team merch — all from your phone, with an AI assistant that actually knows your gym.

RUN YOUR WHOLE GYM • Plan classes on a weekly schedule and track attendance • See your whole training week at a glance with the activity heatmap • Works offline — everything syncs when you're back online

ASK AI ANYTHING • Your gym's data, one question away: revenue, attendance, overdue fees, an athlete's competition prep • Type, talk or send a photo — the assistant handles it • Every answer is grounded in your real schedule, members and finances

TRACK INCOME & EXPENSES • See what you made this month by category: membership fees, private lessons, merch sales, rent • Recurring transactions, payment methods and export

COLLECT OVERDUE PAYMENTS • Instantly see who owes what — and how many days overdue • Send reminders and record payment confirmations

MANAGE EVERY ATHLETE • Full member profiles with belt rank, stripes and promotion history • Organise members by belt or training group • Athletes connect with the free Matsu Athlete app to see schedules and stay linked to your gym

PREP ATHLETES FOR COMPETITIONS • Track each athlete's division and weight class • Keep every registered competition in one place

COACH DIET & WEIGHT GOALS • Assign diet plans and set weight goals tied to competition dates • Log weigh-ins and watch progress toward fight weight

SELL YOUR TEAM MERCH • Manage products, variants, sizes and stock • Take orders and pre-orders from your athletes — sales flow straight into your finances
