Helpful and extensive, but still not optimal

The categories help you to find the correct node, the good, rotary dreidimenionalen pictorial representations show beautifully the structure of the node. Additional information regarding use, advantages and disadvantages are also very helpful.

But the full potential not using this app.
* It is only in English - not bad for the lyrics, but the name of the node is known mostly only in German, and a "bowline" you will not find there halt.
* The 3D rotations are relatively choppy.
* The slider on the right side is also confusing because it looks like a zoom function and will also be shown if it has no function.
* There is a lack of practical guidance hand movements, how to establish the nodes, respectively. You have to deduce from this the building - the animations are here helpful, but not always sufficient. Mnemonics like "The snake from the pond around the tree ..." are also missing.

Conclusion: A useful helper on the go, but which could be much better still by small improvements.
