Knot IQ: 3D Knot Tying

Knot IQ: 3D Knot Tying is a reference app for people who need to learn or refresh knots, from campers and sailors to anyone handling rope, line, or cord at home. By our assessment, its main strength is the 3D angle: knot patterns are easier to follow when you can see the turns and crossings from more than one side. The obvious limit is that knot-tying is still a hands-on skill, so the app can show the steps but cannot do the practice for you. In use, this kind of guide is usually about pausing, rotating, and repeating until the sequence makes sense. Knot IQ: 3D Knot Tying sits in the practical end of reference apps, closer to a pocket manual than to a lesson-heavy course, and that makes it most useful when you already know what knot you need. It is less convincing for people who want broad outdoor instruction or a big library of unrelated topics.
