Community Voice & Feedback
3D and animations. Organized and easy to find your knot. Great work, glad I got this.
It’s an amazing app. It makes it quite easy not only for adults, but for young children to learn how to make knots
I said what I said
For learning a new knot, or understanding an old knot, i have not found a better app. The explanations of origin, uses, and relationship to other knots are extremely helpful. It is like having an animated version of Ashley’s Book of Knots in my phone.
One of my most used and most favorite apps
I absolutely love this app. It gives clear instructions for many knots. The animations are in 3D and very helpful. I recommend it to everyone.
The best knot tying app I’ve found. Clear and easy to follow instructions and 3d video. And lots of knots organized in popular fields of use.
With this app anyone can master the knots they will use in their daily lives, their hobbies and their jobs. The clear and colorful animation is easy to understand and follow, and once you learn a knot, practicing will make tying effortless.
Handy and well diagrammed.
This app is worth every penny, if you want to learn to tie knots. It’s easy to use absolutely loaded with knots.
Valuable knowledge. I learn a lot from this app.
It’s a great app to find a quick knot and to see how it’s visually done. Easy to follow and save favs. Customer service service is great if not even better than the app itself I highly recommend.
Been using this app for about 12-13 years now. Simply the best app!
This app has a wide range of knots for all kinds of tasks. My favorites are the fishing knots—the detailed animations make them easy to follow along with. Say goodbye to YouTube! My only suggestion would be to add even more knots. Thanks, team!
My dad bought me this app at least a decade ago and I still use it to this day to catch up on my training.
Used this app extensively many years ago to achieve the rank of Eagle Scout.
