Such a good app. Heaps of knots to learn, and the way they're presented is very easy to understand. I am a scout leader and my cubs find the explanations easy to follow too. Contacted the developer to see if they could add some shoelace knots, and they were very responsive.

this is pretty good that it has instructional videos that show how to make the knot and you can adjust the speed. and I just learned that you can progress and rewind the video just by swiping your hand over the front of the knot as you're viewing it. brilliant

Ah, but you can! Use your finger to "scrub" over the knot. Drag your finger right to advance the animation and drag left to rewind -- an "invisible slider" if you will. Go fast or slow. Cheers!

It's a great app nice interface and use of an specific use of a database. Things to improve: The new 3D view should work while the knots are made. Right now the 3D view is just at final step, it will be good to move the camera freely while the knots are constructed.
