Have you ever wondered what a knot looks like rotated 40° or maybe 90°? Or maybe you want to see what a Bowline knot or Constrictor knot looks like from the back? Use your finger to spin the knot and see how it looks from any angle in 3D!

Choose from 121 different knots and see how they're tied in incredible detail. Watch the knot draw itself or use your finger to tie and untie the knot. Its easy to see where the virtual rope goes in and out and around. (Something about a rabbit and a hole and a tree right? ) Zoom in on the knot to get a closer look or flip it around for another perspective. Can your old school knot app do that?!

Superb in every way - 5 Stars!
I'm a fairly handy guy (surgeon) and rely on several knots in my practice. Nevertheless I'm pretty hopeless at learning new knots and remembering them, even though I'm a sailor and do some fishing. Knots 3D is the answer. I love every aspect of the app.

Great App - 5 Stars!
I really like this app, I have 4 knot apps, and I use this one the most. As a firefighter rope skills is a must and this app helps keep me "knot prepared". The zoom and step through the knot using a finger gestures is real handy. The author updates this app with new knots often. I recommend this app.
