Grappling Journal & AI Coach
Every detail of your BJJ journey — tracked, analyzed, and improved.
Train BJJ is the all-in-one training companion built specifically for grapplers. Whether you're a white belt logging your first class or a black belt fine-tuning your game, Train BJJ gives you the tools to train smarter and progress faster.
LOG EVERY SESSION
Track all 5 session types — Class, Open Mat, Class + Open Mat, Private Lesson, and Competition. Add notes, tag techniques with position and outcome data, set focus points, and capture everything that matters before the details fade.
LIVE SESSION TRACKING
Start a live session and track rounds, submissions, and taps in real time — right from your lock screen. Round timer, interactive counters, and Dynamic Island support mean you never have to fumble with your phone between rolls.
AI-POWERED COACHING
Chat with your personal AI training coach that knows your game. Get post-session insights that break down what worked and what didn't, with specific technique recommendations. Scan your handwritten notebook and let AI convert your notes into a fully logged session.

Absolutely love this app. It’s become one of the few tools I genuinely rely on. The ability to quickly log techniques, review positions, track progress, and keep training notes organized makes it incredibly useful between classes. It helps me remember details from rolls, spot patterns, and stay more intentional with what I’m working on. Clean, easy to use, and actually valuable for real training progression. Highly recommend for anyone serious about improving on the mats.
