I really like this app. I also love that the translations actually mention the name of the knot as we know it instead of just a translation of the english name. It could be improved by mentioning if each knot is constricting like other apps do. Which knots I could use in rain or after putting lots of strain on it if I want to undo it at some point.

This is by far the best Knots teaching/demonstration app I have seen. I have tried lots of them and this one is worth every penny. I have used it for several years. Dont waste your time with the sad free ones out there. The animations are great and you can rotate the view and rock it back and forth to really see and understand whats happening.

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!
