Never lets you down

Indispensable - buy some paracord and practice in your free time.

Very useful App!!!

Love this app, and use it a lot.
Sometimes, I’ll just sit and scroll through all the different knots, learning what the proper applications
are for each one and then how to tie it…
It’s quite useful for
sure.
I give it 5 stars

Great knot reference.

This is a great app to learn new knots. The animation lets me see exactly how the knot should be tied and what it should look like when complete. The variable speed help me with new or complicated knots. The descriptions are useful to help with selecting the proper knot for a task.
While I only use knots for recreational and personal use, I reference this app regularly.

I wish the rope didn’t lengthen

This app is awesome. Except for the string lengthening as it maneuvers around each knot when you watch the example. This is not how rope works, so this adds extra mental labor to figure out how to actually execute what I’m seeing and plan for all the twists and ties when the rope I’m shown simply grows and the rope in my hands does not. It makes my head hurt.
