Knots 3D: 33 knots FREE, 70-plus knots $1.99, iPhone, iPad, Android
Tree care climbers will enjoy this app for practical reasons, and non-climbers will just like playing with it to see how many knots they have no idea how to tie. The free version includes 33 knots and a $1.99 version has 70-plus to learn. Not all are climbing-related, but even the free version has nine of the most common ones used by technical arborists. What is great about this app is the 3D animation of each knot that can be slowed down, rotated or reversed so you can really understand how the knot works. It also includes handy info on where these different binds can be used.
Perfect for arborist training, learning something new or brushing up on a knot you haven’t used in a while.
