## Description

The GrappleMap — 601 positions, 1,485 moves, every joint placed by hand — as an offline app. No account, no ads, no tracking. Three ways in.

A map of grappling, in your hand.

RookFlow is the GrappleMap — 601 named jiu-jitsu positions, 1,485 transitions between them and 7,722 hand-placed keyframes — as an app that works with the radio off. Every position is a place. Every technique is a road. What you can do from where you are is exactly the map's edges: nothing made up.

Pick any position and see what is actually possible from it. String moves into sequences. Or just watch a match play out, move by move, at your own pace.

THREE WAYS IN

HELM — You are halfway through a roll. Explore all possibilities. The live pair on top, every legal continuation in the thumb zone below. Drag a move to scrub through its real keyframes; let go past halfway and it commits. Set a destination and follow the route there. Switch on Handles and the body is the menu: every joint with somewhere to go is tinted, and pulling one takes the move it belongs to.

DRILL — Pick a chain. Rep it till it's yours. A sequence of moves going round on a loop, with a rep counter and a goal of 5, 10 or 25. Five classics are on the shelf: hip bump to mount, pendulum sweep into the triangle, knee slice to side control, the shrimp back to guard, and the long one from the feet to the choke. Make your own from the trail you walked in Helm, from any two positions, or from the exchange you just watched in Roll. Half speed, quarter speed, mirrored, step by step — and a chain is a link you can send to a training partner.

ROLL — Five minutes. Somebody's gotta tap. Two people sparring their way through the map, a broadcast-style scoreboard, and a coach's notes in the corner.

FIND ANYTHING

Search all 601 positions by name, tag or citation. The filter chips only show tags that would actually split what you are looking at, each with the count you would keep — 161 tags, no taxonomy to learn. Every position lists its sources: the books, videos and instructors it was checked against.

3D, ON DEVICE

Both grapplers are rendered live from any angle. Rotate, zoom, step through a move forwards or backwards. Roll in the academy, a real gym photographed in the round, or in the dark room. The pair can wear the Shonen look, inked like a manga. Where the device can do AR, the mat stands on your own floor, at full size.

OFFLINE, AND HONEST ABOUT IT

• The map ships inside the app. Nothing loads, nothing syncs.
• No account. No ads. No tracking.
• Three things ever leave the device, and none of them says who you are: an anonymous crash report if the app crashes, anonymous usage statistics (which screens and courses get used), and the GrappleMap repository's star count on the credits screen. The first two have a switch each. Offline, a dash appears where the number would be.
• The data is Eelis van der Weegen's GrappleMap, in the public domain. RookFlow renders it exactly as written.

iPhone and iPad. On iPad, landscape puts the position beside its moves.

English, German, Portuguese, Spanish, Japanese, French, Italian, Russian, Korean and Polish.

RookFlow is an independent tool, not affiliated with or endorsed by any federation or academy.
