About this app

matday replaces the notebook, the WhatsApp group, and the spreadsheet with one app built for how BJJ academies actually run.

Attendance that actually works
Each class gets a unique QR code. Members scan once and they're logged — 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.

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

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

Attendance history for every member
Full 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.

Personal training log
Log your own training sessions independently of academy classes — track duration, notes, and personal progress over time.

For owners and instructors
- Create your academy in two minutes
- Set your recurring schedule once
- Approve or decline membership requests
- Manage belts and stripes after promotions
- Transfer ownership when needed

For members
- Join your academy with a 6-character code
- RSVP for upcoming classes

What’s new

Staff can now check in members who walked in without registering, directly from the session view. Swipe left on any member in a session to check them in or cancel their check-in. Tapping a member now opens their full profile with all management actions, from anywhere in the app. Session dates can be rescheduled individually without affecting the rest of the template. Kids and juvenile belts are now fully supported. Various performance and stability improvements.
