BEST KNOT APP
Not only is this a great app for new knots but a fantastic refresher course for forgotten ones! I love the way the knots tie in 3D. Helps you to visualize the process of tying the knots that words and 2D schematics fall short on. With the help of this app, everybody will think that you are an expert. I do recommend this app to all in need of the art of knot tying
