Knots 3D

By Nynix

Open iTunes to buy and download apps.


Tie, untie and rotate more than 90 knots with just your finger! Knots 3D will give you a whole new perspective on knots! Grab a rope and have fun!

- #1 Reference App in 75 Countries*
- Included in Scouting Magazine's "Ultimate List of Scouting Apps" and featured in the Trek Tech section of the Sep/Oct 2012 issue.

Have you ever wondered what a knot looks like rotated 40° or maybe 90°? Or maybe you want to see what a Trilene 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 94 different knots and see how they're 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!
I'm a fairly handy guy (surgeon) and rely on several knots in my practice. Nevertheless I'm pretty hopeless at learning new knots and remembering them, even though I'm 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 4 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.

What's New in Version 4.1.0

We have added some of the top user requests to Knots 3D: A search function and landscape mode -- iPad owners rejoice!

The landscape mode is perfect for teaching knots on a big screen TV or projector using AirPlay and an Apple TV. It also accommodates those using iPads in landscape due to keyboard or case restrictions.

The search function searches all knot names along with common synonyms and works in all 16 supported languages!

We continue to add new knots and this time we have (finally) implemented the classic Turk's Head Woggle!

Lastly, we have modernized the user interface with four selectable color schemes (skins). To those who loved the gradient... Sorry, it is gone. For those who hated it -- hope you like the update!

- New knot: Cowboy Bowline (AKA: Dutch Bowline, Left-hand Bowline)
- Minor Translation update
- New earth tones color theme

- Landscape mode
- Search function
- New knot: Turk's Head Woggle
- Double tap zoom in/out
- Modernized UI (4 user selectable themes)
- Turkish and Hebrew translations
- New settings screens
- Various performance improvements and bug fixes

Customer Reviews

Knots everywhere!

For a guy who always had Knot issues, lack of patience and general frustration, this app has really helped me. I am building my Bushcraft skills and a very important element to Bushcraft or anything outdoors is knot tying. The real beauty of this app is having it everywhere, a sort of trainer that is right there with you. The ability to slow the tying in the video is brilliant! I use that feature to repeat steps until I get it right. I can now say I know how to tie a few knots and am increasing my skills constantly. Thank you for this app!
Yes I will and have recommended this app to several friends.

Well worth the price

Nice updates-thanks for the new knots.
◾Extensive library of knots.
◾Knots can be rotated for viewing from any angle.
◾You can step through the animation by sliding your finger across the screen.
◾The ABOK numbers provided refer to the Ashley Book Of Knots, for further research.
Stepping through the animation is as good as having an expert guide your hands through the process.
This app, Pro Knot and Knot Guide comprise my iPhone reference library for knot tying. When I'm stumped by the other two apps, 3D usually shows me what I'm missing.

Excellent tool and helpful reminder for infrequent knots

I always get frustrated trying to follow video demos or 2D examples. There is always that gap or bad angle the leaves me exclaiming "but how did you get that from the last step!" Or some variation that I shouldn't reprint. This app makes it so clear and the pause and speed control too. Perfect. Browsing the samples also allows choosing something more appropriate for what you are trying to accomplish as well. Now if you just had an Oragami / money Oragami app!
