Built for Jiu-Jitsu gyms

Management software for Jiu-Jitsu gyms

Bring students, classes, attendance, monthly fees and your whole operation into one place, without spreadsheets and endless WhatsApp threads.

If you are looking for software for your Jiu-Jitsu gym, IMUA Checkin was designed for that routine: classes by belt, guard drills and rolling, students joining and leaving classes, and fees to follow every month.

What you can manage in IMUA

Six areas of the gym in one dashboard. Tap any of them to see how it works.

Students and groups in a single record

Every student has a profile with contact details, plan, training history, attendance and health form — which helps you decide who is ready for the next grading.

Students and groups in a single record

Classes and schedules organized by level

Create recurring or one-off sessions with time, mat or room, lead coach and number of spots. Students see the live schedule on their phone and you follow, session by session, who confirmed and how many spots are left.

Classes and schedules organized by level

Check-in and attendance without paper lists

Students confirm attendance from their own phone and the spot is booked instantly. When a class fills up the waitlist takes over: if someone cancels, the spot goes to the next in line. You arrive at the mat already knowing who is coming.

Monthly fees and payments closely tracked

Set up the gym's plans, link each student to one and see who is up to date and who is overdue. With Mercado Pago connected, students pay by Pix or card inside the app and the status shows on your dashboard.

Monthly fees and payments closely tracked

Visitor management with its own page

Your gym gets a public page: anyone who wants a trial class picks a session with an open spot, fills in their details and health form, and the request reaches you to approve, reschedule or decline.

Reports to see the operation

Attendance per student, class capacity and the history of sessions and private lessons are all recorded. Instead of relying on memory, you check the numbers before opening a new class or changing a time slot.

Frequently asked questions

Does IMUA work for Jiu-Jitsu gyms?
Yes. IMUA organizes students, classes, attendance and fees for any sports business — and for Jiu-Jitsu that means classes by belt, guard drills and rolling.
Do I have to migrate everything from my spreadsheet at once?
No. You can start with one class and a few students, see how it works in practice and bring the rest across as the gym gets used to it.
Does it work for small gyms?
Yes. IMUA works the same for one coach with a single class and for a gym with several coaches; only the number of sessions and students changes.
How does student billing work?
You set up the gym's plans and follow each student's status. Connect your Mercado Pago account and students pay by Pix or card inside the app, with the payment recorded on your dashboard.
Do I need to install anything from an app store?
No. IMUA is an installable web app: you and your students add it to the home screen straight from the browser, on iPhone or Android.
Can someone who is not a student book a trial class?
Yes, through your gym's public page. They pick a session with an open spot, send their details and health form, and you decide whether to approve.
Do I need internet on the mat?
IMUA works online, but in practice students check in before training — you arrive with the attendance list ready on your phone.
