I really like this app. I also love that the translations actually mention the name of the knot as we know it instead of just a translation of the english name. It could be improved by mentioning if each knot is constricting like other apps do. Which knots I could use in rain or after putting lots of strain on it if I want to undo it at some point.

This is a terrific, authoritative guide to a wide variety of essential, general-purpose knots as well as a great selection of less frequently seen but popular specialty knots for unique real-world purposes. The visual demonstrations are great and you can control the speed, stop and start, and vary the viewing angle. The text descriptions and caveats about a knot's performance and limitations are also very good.

I was looking for a quick reference for technical rescue applications as well as training purposes. We have a lot of go to knots but I use many infrequently and this is a great tool to quickly recall past knowledge. Haven't paid for an app for years but the reviews convinced me and I was not disappointed. Great work and can easily teach a novice.
