Learn to tie over 240 knots for fishing, climbing, boating, sailing, camping, scouting and other ropework. Knots 3D is the original 3D knot-tying app, first released in 2011 and rated 4.9 by tens of thousands of users worldwide. Choose a knot app with care, as your safety may depend on it. Watch each knot tie itself in 3D, slow it down, and turn it around until it makes sense. Browse by category or type, search by name, common synonym or Ashley Book of Knots (ABoK) number, or describe what you need the knot to do. Save your favorite knots for quick review. Features: - 241 knots in over a dozen categories, with new knots added regularly - No ads, no subscriptions and no in-app purchases. Ever! - Completely OFFLINE and self-contained. No additional downloads or internet access required! - Watch knots tie themselves and pause or adjust the speed of the animation at any time - Rotate knots in 360-degree, 3D views to study them from any angle with a swipe of a finger - "Scrub" over the knot with a finger to advance or rewind the animation - Mirror (left-hand) mode, zoom, and rotate the view to match how you hold the rope - Describe a task in your own words, like "tie a boat to a dock", to find the right knots for the job - High-res graphics with photorealistic rope textures - Dark mode and light mode - List, Card and Icon view options - Create your own custom categories to group knots, such as "Mastered", "Practice" or "Top Ten" - Add personal notes, links and your own search keywords to any knot - Share a knot link by text message, email, social media and more - ABoK numbers for cross-reference to The Ashley Book of Knots Includes the knots people look for most: Bowline, Clove Hitch, Figure Eight, Trucker's Hitch, Square Knot, Sheet Bend, Prusik, Taut Line Hitch, Cleat Hitch, Palomar Knot, Uni Knot, Double Fisherman's Knot, Alpine Butterfly, Monkey's Fist, Munter Hitch and many more. Every knot comes with a description of what it is for and a list of common uses. Most also include the other names the knot goes by, strength and reliability notes, structure, related knots, ABoK numbers and history.

I think this app could be the go-to app for knots. I am going to be a little critical, because want to see this app succeed and improve, so I held back a star. It’s a great app and will help all those who need a knot reference on the fly, and especially where wireless signals may not be reaching you. First: the animations need a restart from beginning feature. I don’t get things at first cue, and want to repeat the steps. A simple restart the animation option would relieve a lot of frustration of having to rewatch and mess with the animation speed trying to find the beginning stop again. Heck, if the makers want to get this app super premo, the animations could have chapters. If the makers don’t want to spend the time doing so, let the users put their own bookmarks in as chapters, and they then can skip to the steps they need refreshing on! Second: the heart is great, then you can pick you favourite and navigate to it easily, but what if the app had a rating for knots, then a user could try similar knots, and rate their favourite and so that the community could push usefulness and popularity to the top. There are a lot of knots out there that this app doesn’t cover and some better than what’s on here, so user feedback could allow the cream to rise to the top. This app has the potential to be the modern knot Bible. Wouldn’t that be sweet, a social media community app for knots! Hey, there’s even opportunity to market rope and cordage through this app. Heck, I am liking these ideas so much, I should buy the rights and develop it - but that’s not my expertise. Any takers?

Haha, thanks for the feedback! FYI, you can “scrub” back and forth over the knot with your finger to advance or rewind the animation. There is also a setting to continuously loop the animation so you don’t have to drop the rope to click the play button. Your other suggestions have been noted. Thanks for taking the time to rate and review. Best regards, Knots 3D team.
