Grapple Flow is the position map every grappler wishes they had on day one. Every position. Every transition. Every submission. All connected on one interactive graph — across BJJ, Catch Wrestling, Judo, Wrestling, and Sambo. — BUILT FOR HOW GRAPPLERS ACTUALLY THINK — Grappling isn't a list of moves. It's a network. Side control connects to mount connects to north-south connects to back. From every position, there are attacks, escapes, and transitions. Grapple Flow shows you the whole map — and lets you walk it. Tap any position to see: - Every attack you can hit from there - Every escape you can chain - Every transition that links it to the next position - Video for the techniques (255+ wired and growing) - Common counters and your opponent's likely reactions — FIVE STYLES, ONE LANGUAGE — Toggle between Brazilian Jiu-Jitsu, Catch Wrestling, Judo, Wrestling, and Sambo. See how the same position is attacked differently in each style. Cross-train without losing the thread. — PATHS: PRE-BUILT CHAINS + BUILD YOUR OWN — Common Chains: 78 hand-crafted multi-branch sequences across the 8 most-attacked positions (Closed Guard, Half Guard, Mount, Side Control, Back Control, Standing, Spider Guard, X-Guard). Each chain shows the initial attack, the opponent's likely reaction, and your follow-up — with hand, hip, and foot logic spelled out. Custom Paths: build your own sequences from any starting position. Save them, name them, drill them. — TRAINING JOURNAL — Log every roll: partners, submissions landed, submissions given up, what worked, what didn't. Tag partners by username. See your win/loss by opponent. The stats surface patterns you can't see in the moment. — MY GAME + BELT TRACKING — Map your A-game. Mark the positions you live in and the ones you avoid. Track belt promotions and stripes. Set goals. Watch them close. — FREE + PREMIUM — Free: explore the position graph, watch technique videos, browse the glossary.

MatNotes is how a jiu-jitsu academy makes the details from class actually stick. Coaches film a technique right after teaching it. Sixty to ninety seconds, phone propped on the mat. Students get it that night, then again on a spaced schedule (day 1, 3, 7, and 21), the same rhythm your memory needs to hold onto something new. Instead of "I saw that grip once and forgot it," the move keeps coming back until it is theirs. FOR STUDENTS - A simple checklist of what to review, not an endless feed - Watch tonight, then again each time the app brings it back - Slow any video to half speed and loop the exact section you are stuck on - Tap a moment in a video to ask your coach a question, with the timestamp attached - Keep private training notes and track the techniques you have drilled FOR COACHES - Film once, and the app resurfaces it for every student on the right days - See your students' questions, with the exact video moment, before class starts, so you know what to clean up - Spot where the room got lost on a technique and reteach it - Everything you have filmed, captioned and searchable by position, in one place - Your academy's name and colors throughout MatNotes is used by a whole academy under one plan. Coaches set up and manage their gym on the MatNotes website. Students join with a link from their coach and use the app for free. Questions? Visit thematnotes.com
