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.
Premium: Paths, My Game, Training Journal, Belt & Rank tracking, cloud sync across devices. 7-day free trial. Founder pricing — first 1,000 monthly subscribers lock in $2.99/mo for life.
