## What is SubMetrix?

SubMetrix is the advanced Jiu-Jitsu tracker built for serious grapplers and academies. Turn every roll into data, find your weak spots, and watch your game evolve.

TRACK EVERY ROLL
Log sessions in seconds — Gi or No-Gi, rounds, intensity, duration, and partners. Build a complete history of your mat time and training volume.

COMBAT INTELLIGENCE
Record every submission you land and every tap you give up. SubMetrix turns it into a clear picture of your game: your Lethal Weapon (your highest-percentage finish), your Critical Weakness (what keeps catching you), and your Nemesis (the positions costing you rounds).

KNOW YOUR NUMBERS
Clean dashboards break down your submissions, positions, takedowns, and progress over time — so you stop guessing and start training with intent.

FLOW MAPS & GAMEPLANS
Chain your techniques into flows and build tournament-ready gameplans. See exactly how your A-game connects from takedown to finish.

MENTAL RECALL
Sharpen your knowledge with BJJ flashcards and terminology quizzes spanning positions, submissions, and concepts from white belt to black.
