BJJ Log10Catch members before they quietly slip away
Attendance, memberships and classes from your phone — free for members, a retention tool for you.
A jiu-jitsu gym loses about half its members every year. Most of them don't leave angry — they just quietly stop showing up. And the signal always comes first: three times a week drops to once, two weeks pass, and then they're gone.
BJJ Log10 watches for that signal so you don't have to.
Three things that keep your mats full
🎯
Attrition radar
Every day it surfaces who hasn't come in over two weeks — plus members quietly cooling off from 3×/week to 1×. One message can save a member.
🎖️
Promotion radar
The #1 cause of quiet churn is "my professor forgot my promotion." From attendance data, it flags who's due for review — so you never forget.
⏱️
30-second attendance
Members scan the QR on the wall — done. Faster than paper, and who trained when piles up on its own. No app install required.
Open the app. This is the first thing you see.
Three numbers, every morning: who owes fees, who is quietly slipping away, and who is due a promotion. No report to run, no list to keep.
- Tap a card and the roster filters to exactly those members.
- It builds itself from attendance — you never maintain a list.
- Nothing to chase today? It tells you that too.
