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 118 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.

Customer Reviews


I love this app! You can work at your own speed and everything is in 3D. Very easy to understand and interactive. I have to admit, I had very limited knowledge of knots before using this app. I knew a few fishing knots and that was it. I am a hands on learner and it takes me a while to figure thing out. I hate to admit tha, but it's true. This app lets me deconstruct the knots and look at them and work at my own speed. I bought this on a whim, because I am going on a bike tour this summer and thought, "Why not." Once I actually started using the app, I have begun to use this app and I have successfully ties several knots. All a success! If your not that skilled with tying knots, I highly recommend this app. It is definitely worth the 4.00 cost. So glad I got this app.

Knot Your Average Guide to Knots (Well Done)

Knots 3D is brilliant! Within minutes of launching this app, I have tied a good number of knots which have eluded me when using static images of the same knots. The color contrast works nicely and the scalability and rotation features are immensely helpful.

I don't know how Knots 3D compares to other similar apps, but for my needs I cannot imagine needing anything other than this fine program. The developers should be commended for creating such a useful tool, especially one which is free to use and free of pop-up ads.

If you are just learning to tie knots, or are just in need of a refresher, I whole heartedly recommend getting Knots 3D right away.

Love this App! Knots for every purpose.

Wanted to fish again, & this App with it's 3D capabilities makes learning new knots so easy. The ability to speed up or slow down the animation is a really nice feature that makes understanding the process much easier. Set favorites easily so you can get to the knots you need right away.

All in, this is a great App for everyone. Knots are needed all the time in everyday life and 3D knots lets you learn the proper tool (knot) for the job.

Great App!
