Knots 3D App

Knots 3DTie, untie and rotate 101 knots with your finger in 3D!

Knots 3D, our popular how-to knot app, will give you a whole new perspective on knots! Have you ever wondered what a knot looks like rotated 40° or maybe 90°? Or maybe you want to see what a Trilene 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 101 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?!

Very Useful – ★★★★★
Great guide for knot how to’s. 3D ability puts it to the top compared to others. Nice job dev’s.

Great App – ★★★★★
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.
