I've also bought this app on Playstore, a couple of years ago, but for me it's sort of useless. Yes, you can try to follow the picture, but that's usually not how you tie the knot.

I wish this app would show how to tie the knots efficiently with your hands, like in this video [1]

I just installed the app and I can switch the view horizontally and vertically, rotate the view 360 degrees and change the speed. I can also incrementally step forward and backward through every step of the knot tying process by swiping my finger up and down. I could not ask for a more thorough example of how to tie a knot.

The app doesn't actually show the knot tying process for many knots. Yes, any knot can be created by carefully weaving one open end through the entire process (what is shown). But that's not how many (most?) knots are actually tied in practice. And for many knots it would be impractically difficult to tie it this way.

I think I understand what you mean, but what would that 'extra context' look like?

For example, could 'practical' knot tying be modelled as a sequence of states? So one state would be 'untied' and then the next might be 'looped under', then 'end passed through loop' and so on?

If i think about the enormous pain i had when first tying a bow-tie... then realistically there are all sorts of details like which hand you hold which part with :/

do you have any examples of knot tying process? I am honestly not 100% sure what you mean but curious to learn more.

Here's an example[1] at random from YT. Many knots can be tied multiple ways (that still result in the same knot), and many knots can be tied with slight variations (for example lots of things can be slipped by finishing the knot with a doubled-over bight instead of just the single line, allowing you to pull the 'tail' and quickly untie them).

I know not everyone has (or supports) instagram, but this account is nothing but hands tying knots in different ways, and I love it: https://www.instagram.com/knotsandcues/

i had it already installed too. took a look at it and it now includes a 3d animation showing how you tie the knot. It's pretty good.
