Attendance history

See who shows up.

Full attendance logs per session and per member. See who registered, who checked in, and who didn't make it. Members can see their own history. No more end-of-month guessing about who deserves a stripe.

Class schedule

Set it once. Run it forever.

Define your recurring classes — Gi on Monday and Wednesday at 19:00, No-Gi on Friday at 18:30. matday generates the sessions automatically, 28 days ahead, every night. Modify or cancel individual sessions without touching the template.

QR Check-in

One scan. Every session.

Each class gets a unique QR token. Members scan it on their phone and they're in — no sign-in sheet, no manual entry. Walk-ins work too. The attendance log updates in real time so you always know who showed up.

Member roster + belt tracking

Know your academy.

Every member in one place: belt, stripes, role, and membership status. Approve join requests, update belts after promotions, and see who's active versus lapsed. Instructors can manage members; owners have full control.

Create your academy

Members check in

Share your QR code at the door. Members scan once per class and they're logged. No app install required to check in.
