Absolute the best most convenient and accessible way to access the knowledge of knots. It's an easy to use app a very easily digestible teaching format go at your own face slow down speed up flip it over reverse it does everything so that you know how to tie every knot everyone wanted to know I would have paid more! This is not a paid review I am a real person who spent their real money on this app.

This is one of the few essential apps I have on my phone. I have this open every time I'm messing with rope, line, or even string (midshipman's hitch: great for hanging plants from old pulleys on the ceiling, as it turns out!). They're consistently adding new content, the speed of the animation can be changed, the animations are clear and accurate, and the convenience of an app is all I could ask for something so fascinating and important. Better than looking up knots every time online for sure!

Great app for knots. The pause function allowing the knots to be advanced slowly by pressing a button is really helpful. The only reason I don't give it 5 stars is because I'd really like to see different (easier) methods to tie the more difficult knots, as I've seen in other videos, but this is really variable based on the individual, and I'm really having to nitpick to find something I'd like to see improved based on my opinion. Overall a very helpful app. The best of all the apps I've found.

Hi and thanks for the suggestions. One thing you might not have discovered yet is in addition to the play/pause button, you can use your finger to "scrub" across the knot to advance/rewind the animation at your own speed. You can also rotate to whatever angle you want using 2-finger "twist".
