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 126 different knots and see how theyre 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!
Im a fairly handy guy (surgeon) and rely on several knots in my practice. Nevertheless Im pretty hopeless at learning new knots and remembering them, even though Im 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 four 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.

Pros and cons of Knots 3D app for iPhone and iPad

Knots 3D app good for

This app is so useful i use it any were no wifi needed I can use it in camping thanks a lot.
Ive been a knot geek since I was Scout, and this is a great app for novice as well as skilled knot masters. One of the problems with knot books has always been the clarity of the illustrations. This app trumps all of those, providing beautiful 3D animations that clearly show the construction of each knot. Even better, you can scroll the animations back and forth, stopping along the way, and you can rotate knot in space to see it from all sides. In addition to the great animations, each knot comes with some background info on the knots origins, alternate names, and sources for the info. Great app!
Easy to understand, great visuals. Glad to have UK among language choices. Its nice to not have to endure US spellings. :)
Great app but it wish they would show the end when the loop is pulled taught.
Use this everyday to help teach guys I work with in the scaffold industry. Beauty!
Ideal for us maladroits, and good, I am sure, even for experienced sailors. Superb animations.

Some bad moments

Animacje w appce nie są płynne, np. zwykłe przewijanie listy. 5S Animations in app are not smooth, e.g. simple list scrolling. 5S
I cannot say enough about this app. I have learned so many knots from this single app. The ability to slow down the speed limit is showing you how to tie any not is such a huge benefit. I didnt even know this many knots existed! Thank you.just doesnt seem like enough!
Simply a must have. All young men involved in outdoor sports should have this on their smartphone.
This is by far the best illustrated and easiest to follow knot tying app. However, in the past, I still had to have a couple of other apps because there were some knots that Knots 3D didnt have. This has all changed with the recent addition of many more knots listed in the app. Now Knots 3D is the only knot app I need and I have deleted the others.
This app is particularly helpful in all things fishing, hiking, and camping. Masterfully crafted and of a unique, beautiful, modern design.
I knew how to do some "sailor knots", but this app has them all & any kind of knot one may need in Life from sailor, trucking to Firefighters!! Thank-you "The Knot Folks" for doing such a Great job & the animated instructions are the best Ive found anywhere!!
