What apps do best

This is what apps do best. Its an excellent reference for something I need often, but would never carry around a book to reference. Very clear. Spent 1/2 hour having someone try and show me how to tie a bowline and still couldnt repeat it. I looked it up in this app and could tie it from memory in about 5 minutes.
