Knot Now

Knot Now is an offline field guide to 225 knots, animated in 3D, with step-by-step lessons you can follow at your own pace.

BROWSE BY REAL-WORLD USE Knots are organized into camping, climbing, boating, fishing, rescue, arborist, pioneering, decorative, and rope care, plus a curated Essentials set of the eight knots worth learning first. Search by name, use, or classic reference number (ABoK).

LEARN STEP BY STEP Every knot has a slow, scrubbable 3D animation you can rotate, zoom, and play back at 0.5x-2x speed, paired with plain-language steps. Jump a step at a time, or drag the timeline to any point in the tie.

KNOW THE TRADEOFFS Each knot lists what it is good for, its strengths, and what to watch out for, plus a one-tap comparison against a similar alternative for when two knots do almost the same job.

CAST TO A BIGGER SCREEN Send any lesson to a nearby TV or Mac over AirPlay. The lesson video is generated on your device — nothing is uploaded anywhere.

TRACK YOUR OWN PROGRESS Mark knots as favorites, add them to a practice list, or mark them mastered, and keep field notes on any knot. Everything stays on your device.

Knot Now works fully offline. No account, no sign-in, and no network connection required.

For any knot used in climbing, rescue, arborist work, or another life-safety context, verify the finished knot and technique with a qualified instructor. The animations are a learning aid, not a substitute for training.
