Great mutli-purpose knot app!
I have tried a couple apps for knots and grog knots stands way out! I am a amateur climber and knot tying hobbiest and this app is very useful. Great selection of knots with clear written and animated directions. I especially like the info button for each knot. It displays a little history and/or information about where the knot comes from as well as common uses and similar knots. Thanks!
