Useful app
It is a very useful app indeed. It has great visualization. Speed control is great. 3d rotation is interesting though was not necessary.
Having said that these cool features alone must NOT be used to rate this app.
This app MUST NOT be used as the only textbook on knots.
Serious flaw of the app is, it does not show final tightening, dressing and the way the knot must look like after applying the load. We know that proper tightening and dressing of the knot seriously affects its reliability especially when rapid load may be applied to undressed and untightened knots.
But still I find the app useful refresher course for those who know what they are doing. I especially like the Favorites feature.
Another feature that would make it more useful is to list efficiency percentages for knots and to be able to sort knots by efficiency.
Thank you!
