    UPDATE: 5/6/17: This is one app that keeps getting better and better!! No bs permissions. How do I donate to developer? YOU DESERVE IT!! This app truly is worth much more than I paid for, its simplicity and ease of using it's perfect to learn how to make knots. Others similar apps going for two or three times the money are not even close to this awesome app. I hope the developers don't stop improving it. Great job devps!!!!!!! UPDATE: this is perhaps one of the few apps that keep getting better with time. Great job devs!! My updated star rate: 6 STARS!! keep it up guys!! Full Review

    Cool app! The one problem I had was when I watched the monkey's fist, I wanted to turn the animation around as the rope snaked round the back of the marble/ball. I could rewind, fast forward, mirror it, turn it upside down and see the COMPLETED knot in 3D- however, I wasn't able to view it from the other side. That means it isn't actually 3D- it's a 2D animation with rotate and mirror controls with a 3D picture at the end. Still very informative and handy as I own a boat. If we could just turn them 180° horizontally while they play as well as vertically (complete control to spin turn would be even better), I would have given 5 stars. Full Review

    The variable speed dynamic animations make it super easy to learn each knot. However, it only shows 'one' way to tie each knot, some of the older ways were better, (SUGGESTION:) it would be great to have both animations rather than replace them. In saying that, it is still worth it. Full Review

    Excellent collection of the most useful knots. The only thing I've found strange is that this app has a Tiller's Hitch which I thought was called a Becket Hitch, but that name isn't listed at all. It's probably I just have it wrong. Full Review

    I get a great deal of satisfaction and practical value knowing my knots. This app is about as useful a reference as one could ask for: It contains a broad selection of knots while making excellent use of the technology to make itself better than a book - animations make things extremely clear. It's easy enough to follow that it makes carrying around a couple of shoelaces in the car for practice a fun activity for kids or adults. Full Review

    don't like the way the materials is presented. unlike other app, the middle steps are shown more naturally, like a human is actually doing it, this app is more like help you trace a rope on a tied knot. not very helpful Full Review

    Animations can be hard to follow as it is showing the free ends snaking around Instead of trying to animate movement as if you were tying it. Still a good variety of knots. Full Review

    This is so easy to use! My memory for knots was never good, and who carries a book around. But now I have the info always with me on my phone, and the 3D animations are a great way to learn. Stop making Granny knots, learn the correct way from this app. Be safer when climbing or trying to keep a tent from blowing away in the wind. Full Review

    This is an amazing app! I love how it works and looks! A total must have app. The designs are really amazing and really accessible it's just amazing. However, it does need more improvement in certain areas. In one hand, it needs to improve on explaining more about the knots and showing how they work. on the other hand, it also needs a little of improvement on the 3d effects and what it is capable of doing with such effects. For example, the 360 effect does not work when you are learning how to do the knot. I feel they should improve this to fully see the Making of the knot on every angle. Also an explanation of what to do with the knot to make it tight or loose. Don't get me wrong, I'm happy with my purchase, the app is amazing and I'm in love with it. This is just a suggestion from a happy costumer who wishes to get more of this amazing app. A way of improving would be a fully explanation of the knots. For example, how they work and in what situations. if male it tight or loose or how to make em tight. More beginner friendly in some sort of way. Furthermore, the 360 effects should be on when they are showing how to do the knots. This would help view it and understand it more from every single angle. At last yes more and more knots please this needs to continue. I know you are working hard on this app which I'm glad to have bought. keep up the good work and thanks for your time. Sincerely : A happy costumer who wants more of this app. Thanks for your time again. Full Review

    Amazing! I got it for free Nov. 3, and I think I might have paid for it. They have 3D videos on how to tie knots, which you can rotate, speed up or slow down, and even uses of the knot! 10/10 app. Full Review

    All knots are well done and shown step by step. My only problem is that there doesn't seem to be a way to rotate along the x axis to see the top and the bottom of the knot. Other than that it works perfectly. Full Review

    Christopher Garcia Published date: November 3, 2017

    What a great idea. Watching the 3D knots develop (you can pause and adjust the speed) and ability to rotate it 360° makes learning to correctly form the knots relatively straight forward. Includes notes about each knot (uses, history, strength, etc.). Knots are categorized by subject (e.g. boating) and by type (e.g. loops). You can save favorites, too. Pretty cool. Full Review
