02The map

Every position is a place. Every move is a road.

The GrappleMap is Eelis van der Weegen's — 601 named positions, 1,485 transitions, checked against the books and given away. Nothing here exists without it.

What you can do from a position is exactly its edges. Nothing made up for the app.

Half guard, the position you are in, with three routes leading out of it — a kimura, an arm triangle and a sweep to mount. Each is a pair of grappling figures drawn from the GrappleMap database. Half guard · you are here KIMURA ARM TRIANGLE SWEEP TO MOUNT

03iPad

Big screen, wide layout.

Landscape puts the position beside its moves. It's the window that decides, not the device — which is why it also works right here.

Works with the radio off.

The map ships with the app. No account, no cloud, nothing phoning home. Add it to your home screen from the browser and it keeps working on the plane.
