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.

Cant install the latest 10.003 version. It keeps telling me cant install it. Never happened before in updating previous versions. System and storage are not the cause. The update was about 2.8 mb. After uninstalling the app and several attempts to reinstall it. The same screen pop up. (Update: Thanks for the reply. After leaving it for about 20 hours and reinstall the app just now. Nothing pop up and it has been installed sucessfully this time.) Will email you if it persists in the next update.

I have not had any other reports of this and this update was just data(knot and category descriptions) and assets (knot animations). There were no code changes so nothing should be any different from an install or update perspective. Please send me a screenshot of the error if possible to app_support@nynix.com. Hopefully we can find a resolution.

Pleasantly surprised with the quality of the animations showing how to tie some pretty complex knots. I like the pausible animation speed control which helps one to follow and understand the process of tying any of the great selection of knots included with the app. It's very helpful that knots are grouped according to activity or application you need a specific knot for. This does mean that some knots are in more than one group so finding 'that knot' is easy and fast. Good work.
