Your Students, Sorted by Risk
Active, Drifting, or Quiet. Know exactly who needs attention.
Now you can find who is quiet or drifting before they become a cancellation
You're losing students right now. You just don't know which ones yet.
They don't complain. They don't ask for refunds. They just... stop showing up. By the time you notice, they've already mentally checked out.
→ Average gym loses 20-30% of students annually this way
Your check-in system shows who came to class. It doesn't show who's frustrated, injured, or losing motivation. You're flying blind.
→ Attendance is a lagging indicator. It shows damage already done.
Every lost student costs you $1,800+/year in revenue. But worse - they take their training partners, their energy, and your gym culture with them.
→ One preventable loss per month = $21,600/year gone
You probably have 3-5 students right now who are one bad week away from quitting. You just don't know who they are.
What if you could see them before they disappeared?
🥋 Students already use BJJ Notes to log their training. Connect their app to your gym and unlock check-in, retention insights, and BJJ Notes PRO for every student.
A complete early warning system for student retention
Real-time visibility into who's active, drifting, or going quiet. Color-coded alerts so you know exactly who to reach out to before they quit.
Every class becomes part of a knowledge library students engage with between classes. This engagement powers your early warning signals.
Set promotion rules by belt and stripe (min sessions, min months). See who is eligible, approve promotions, and track every student's journey from white to black belt.
Students check in from the BJJ Notes app. No paper, no spreadsheets. See who showed up to each class and connect attendance data to your retention signals.
No credit card required. Cancel anytime.

"Best bjj tracking app on the market. Loving the new updates, belt tracker and the other aesthetic improvements have made it look so much cleaner. Prompt service from the app creator too, would recommend to anyone training. Oss"

"This is exactly what I was looking for. I wanted to journal what I learned in class so I wouldn't forget. But now I love tracking the statistics even more! The free version is enough for now, but I'm considering the full version."
