These nodes app is actually totally great! Classified according to use purposes nodes are listed, and for each node there is an animation of how he is beating. Customary names are recorded, so you can also search for a known node. Finally, there is advice to use purposes or techniques when striking the node. But as always in life, the medal two sides, or the rope has two ends: The translations are really only minimally present. There are only the names of the nodes available in German, which I would claim that some of the names are also wrong. All other texts are in English. So if you can not cope with the animation, should English be able to abgewinnen something helpful to the text. The animations are nicely done, but for more complicated knots or when a lot has to be beaten in a small space, the animations take place too quickly. Use the slider to the right of the animation speed can indeed vary, although it is sometimes difficult to follow the exact course of the rope. A step-by-step guide would be helpful here. Finally, I am not clear on some nodes where a pile or the like to be pushed through. It is in the text, although it mentioned, but the picture is nothing to see and it is not clear whether, for example, an out-looking strap is intended or rather a kind of hole in the middle of the node. However, this is the smallest problem, because sensibly you will try knot once before entrusted to them something valuable. Overall, the app would be worth 5 stars, but for the lack of translation and the somewhat hectic animations I draw each from a star.
Addendum 28.5 .: came with the last update a consistently decent German translation to explaining the respective nodes although sometimes a bit bumpy, but still understandable. There is the fourth star from me. At the animations a little seems to have been "turned". These now seem to run smoother and more understandable. That may be an illusion. The fifth star is for the time being in the waiting position until I am sure that the animations run consistently understood.
