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. Use your finger to spin the knot and see how it looks from any angle in 3D! Each 3D knot has detailed reference information including tying pointers, strength and reliability, structural info, and Ashley reference numbers (ABoK) and occasionally the history behind the knot. The knots are arranged by both category (Boating, Climbing, Fishing, Scouting, etc) and type (Bend, Loop, Stopper, etc). If you find a knot you like or want to come back to later, add it to your Favorites list for quick reference. The complete list of knots can be found on our website:

Added knot; Pretty darn good

Overall very good. And they answered my email and added the double overhand knot to the boating category, so I’m happy.

Great for a novice like me!

I love the 3d animations, and how you can go as slowly as needed to follow along!

3D Knots

3D Knots is my absolutely go-to app. I do a lot of crafting and needlework. Be honest with you, I would be lost without it. I've recommended to quite of my crafting buddies.

Actually useful

I reference this on site when I need a refresher, and use it for fresh ideas as the need arises.

Great app

Perfect for teaching kids basic and advance knot tying. And also explains the reason to use the knot.

Favorites keep disappearing

Great app but favorites keep disappearing. Really frustrating to spend so much time creating a favorites list of the knots I would actually need to then open it up in the field to find it empty. It has happened at least 6 times now over the course of the last 2 years or so. That makes the app pretty unreliable for any professional who wants to use the app as a quick reference in the field. It’s not a quick process to go through and find the right knot so the favorites is a really important part of the app that seems to lack any real reliability.

I can’t imagine who the target market is for this app. But for a guy like me who one day just decided, I wanna learn some knots. This app is seriously legit. It does so much cool stuff! Support this app and go ahead and buy it. They clearly have someone brilliant behind this app’s design. They all deserve to stay employed. That is all :)
