1. 5/5My Go-To Knot Guide!

   I’ve been through quite a few knot “guides” in the App Store, and in my honest opinion this one is hands down the BEST one out there. First off, the repertoire is absolutely amazing. It contains every essential knot that one could ever need on a day-to-day basis, for hobbies, survivalists, climbers, or professionals which job would require some form of knot tying. In addition, it contains lots of other specialty or unique knots, that I haven’t seen in other apps altogether as they are here. Secondly it has the best video/animated how to section I’ve seen out there as well. The graphics are great, and the fact that you can change the speed of the animation as well as it’s orientation/perspective gives you complete control, allowing users to tie even the most difficult of knots with ease. As a bonus, it gives a detailed written description of each knot, as well as information about it’s origin and any adaptations over time. You can even select similar knots by selecting one of the options it gives you at the bottom for a quick change to a different note for the same function. The only way this app could possibly improve, which it already does on a fairly regular basis, would be to add more knots! Although to be fair, I don’t really know how many more knots are out there that aren’t already covered. Take a look at the animations of, but they have available and if you like it, it’s definitely worth the purchase. I’ve been a happy customer for years. Five stars all the way!!

2. 5/5Always Struggled to Remember Knots! “Knot” Anymore!!

   I’m a highly intelligent person and I did sailing for years so when I say I was a mess when it came to knots I hope you understand how out of character that was for me. It didn’t seem I could learn them in any way that could stick with me. I tried and tried until I got THIS APP!!! I’ve climbed with rappelling ropes and done tree trimming, and I literally have whipped this app out while dangling above 50 feet of nothing below me and adjusted my Figure 8 Knot. I even know the NAMES of knots and alternatives because of this app!! I don’t recommend apps lightly, but this is one of the most consistently useful apps I have. It’s extremely clear, and you can slow the making of the knot down in the short animation so you see the key moments in making it. The descriptions are clear and for things like lashing stuff down in the back of your truck, or climbing, sailing, or even ornamental rope work, you can’t get a better or more informative app than this. It tells you where the knots are best used and what their best strengths are. Sure, you can look up more information online if you NEED more, but I find it’s more than enough what this app provides. It’s a concise and immediately useful guide to tying knots correctly every time. I have so many useless apps people have gotten me to download that when there is a great reference app like this, where all the information stays right on my phone even when there is no reception for the internet, it makes a real difference. I can’t recommend it enough; simple, straightforward brilliance.

3. 5/5The best way to learn a new knot!

   I’ve been fascinated with knots since I was a Cub Scout, some 60+ years ago. I still have my first Boy Scout Manual and the only hand notation, in the table of contents, is the word Knots. That’s first thing I wanted to learn, how to tie a good knot. Knots 3D is the first application I bought, when I got my first iPhone, many years ago. I can’t give you a date, but as I recall, it was around 2011 and there were only about 70 knots in the application, at that time. Now, there’s 126 and I expect that number will continue to slowly increase. I have a large, hard bound copy, of the Ashley Book of Knots and it is an excellent reference, but for most of my needs, for the last several years, Knots 3D has been my go to source for learning, and teaching others, how to tie a good knot. I absolutely love the 3D renderings, in Knots 3D and I consider it to be the very best way to learn a knot. I have gifted this app to many of my friends and family members and will continue to do so. So, if you want to learn how to tie a good knot, in my opinion this is the best source you’ll ever find. TinTexas

4. 5/5Best knot app, hands down!

   As a Scout leader, I find this app SUPER-HELPFUL, being able to show someone, (including myself), step-by-step, how to do some really difficult knots, as well as, the easy ones. Sometimes one may not remember, how to do a specific knot tied before, & this app gives you an easy, “oh yeah, now I recall” quick reminder, which is really handy. It’s fun to watch the “lightbulb” go off, so-to-speak, in someone else’s face, as they “get it,” when this app is able to show, (most of the time), with great ease, how to tie a knot, step-by-step. Being able to slow down, or speed up, the steps, as well as being able to turn the view around, to an opposite viewpoint. It’s great! I HIGHLY recommend this app. It is the absolute BEST, at showing how to tie knots. In fact, today, I am telling all of my fellow leaders in my troop to download this app, as we are responsible for teaching some knots to some fellow scouters, and scouts, at an upcoming camp-o-ree. Thumbs up, 5 stars. Kudos to the app developer(s) on such a well-done app!

5. 5/5I Can-Knot tell a lie, This is the best App for Knot-heads!

   I really love this application. I've owned this since 2012 and they have done nothing but made it better. It really is the best application to learn about different knots and how to tie them. Because of the ability to slow down and speed up the actual building of the knot, even if you're not very fast at tying knots you can keep up with the example. It also has examples of knots that you really can use and you want to use. Sailors need to know this information and this is the best place to get it, also it you have ever tied down stuff in a trailer, you need it too! I have built almost every knot listed but there are a couple that I still can't tie but it's no fault of the app. 😊 When I first got this it had about forty knots, now there are over one-hundred and twenty. But don't take it from me, just take a look at the reviews for this application. I don't remember ever seeing a program with reviews like this, I mean this baby really rocks!
