Why Matsu

Built for the mat — designed to grow your gym

For coaches

Run the whole academy from your phone

A merch store without an employee.

Fill in what you sell — the app turns it into a storefront your athletes pre-order from. We handle production, logistics and shipping. Once a month a single box of pre-ordered gear lands at your gym. Payments are collected in-app, automatically.

No upfront stock · No extra staff

One dashboard for the whole gym.

Finance, schedule, events, members, groups and payments — all in one place. No spreadsheets. No second app. No paper.

Finance · Schedule · Members · Payments

Coach every member personally.

Send a diet plan, set a weight goal, update a belt path, schedule a comp, nudge a payment — straight to that athlete's app. They open Matsu and your guidance is already waiting for them.

Diet · Weight · Belts · Comps · Payments

For athletes

Your gym, your game, your progress — in one place

Connected to your coach.

See everything your coach plans for you the moment they update it — diet, weight goals, belt path, comp schedule and payments.

Order from your gym's merch store.

New rashguard? New gi? Pre-order from your gym's storefront and pick it up next month. Pay in the app — no DMs, no chasing.

Track your whole game.

Your personal schedule and your gym's schedule. Weight, diet, belts, technique notes, full flowchart trees — all on your phone.

AI Assistant

Just say it — it's done

Tap the AI button and start talking — it starts recording the moment you press it. Log your weight, set a comp goal, build a 12-week game plan, update your gym's schedule, take a member's payment, plan tonight's class, restock the merch store — whatever the app can do, the AI can do for you in one sentence.

Voice Image Text Talk to it. Snap a photo of a comp bracket or a payment slip. Or just type.
Athlete · voice · "Log 78.4 kg and remind me to weigh in next Monday."
Athlete · voice · "Build me an open-guard game plan for the next two months."
Coach · photo · "Add everyone on this bracket to my comp team."

Not a chatbot bolted on. Wired into every screen.

FAQ

Good to know

How does the managed merch store actually work? +

You add what you want to sell on the Coach app — designs, sizes, prices. Your athletes see it as your gym's storefront and pre-order from there, paying in-app. We handle production, logistics and shipping. Once a month a single box with all the pre-ordered gear arrives at your gym. No upfront stock, no extra staff to hire.

What can the AI Assistant actually do? +

Anything you can do by tapping. Log a weight, update a member's belt, add a class to the schedule, send a comp plan, take a merch payment, build a flowchart, draft a diet — all by asking. Tapping the AI button starts recording immediately, so the default flow is just to talk. You can also send a photo (a bracket, a payment slip, a whiteboard) or type. It's wired into every screen in the app and acts on your behalf.

How does 1:1 coaching work inside the app? +

On the Coach app you open a member and fill in their plan — diet, weight goal, belt path, comp schedule, payment reminders. That same member opens the Athlete app and sees exactly what you set, live. No messaging back-and-forth, no lost notes.

Is Matsu free? +

The core experience is free to try. Coaches who manage gyms unlock advanced features through a subscription. Athletes can use Matsu free, with optional premium add-ons.

When is Android out of beta? +

Both Android apps are in beta. Tap the Android buttons above to download the APK — public release is coming soon.

Do I need both Coach and Athlete? +

No. Pick the one that matches your role. Coaches who also train can install both — they share data through your Matsu account.
