Built for what happens between classes.
You already know most students don't retain what they drill. My Open Mat gives every student a private, position-based notebook — log a technique and how confident it feels in seconds after class. Not a video library. Theirs.
Grading, without the guesswork
You already publish grading criteria. We want to map your belt/stripe requirements straight onto the app, so students see their own readiness and you get a clean view before grading day. We’d shape this around your syllabus first.
Retention that doesn’t rely on willpower
Students who can see progress stick around. “I should work on my guard passing” becomes something they can actually watch build over weeks.
It learns their game, not just their notes
When a student spots a pattern — “if they post their arm, I go to the triangle” — the app turns it into a saved reaction they can pull up before rolling. It’s closer to how a coach actually thinks than a checklist is.
Your students' data stays private — synced securely to their account, never sold, never public.
No — it’s what students do between classes, not instead of being on the mat.
Free. We built this for the community, not to sell it back to you.
Built by a purple belt, for anyone tired of forgetting what they drilled.
