JIUJITSU COACH
Train smarter.
Grow with data.
Log your training, analyze it with real data, and share it with your coach.
The all-in-one PWA built for jiu-jitsu.
Problem
Sound familiar?
You keep training, but the growth isn't visible. The real problem is that there's no system for logging and analyzing it.
White / blue belt athlete
"I can't remember what I learned after class. My handwritten notebook lasted three days."
Newly competing athlete
"I want to review a lost match, but with no record, I don't know what to fix."
Coach / Instructor
"I can't see how my students are training. I give advice, but I can't tell if it's being applied."
Core Features
Everything jiu-jitsu needs, in one place.
Feature 01

- ✓ Weight & InBody log

Plan your attacks and counters for each position ahead of time. Use it to review before a tournament or after sparring — a way to organize the "game plan" that's in your head.

What is a PWA? Do I install it from an app store? ＋
No App Store or Google Play needed. Just "Add to Home Screen" from your browser, and it works just like a native app.
