This App is GREAT!
I have had this app for over two years- I find it invaluable! I am able to re-learn long forgotten knots used in scouting and I use it for reference for countless practical applications.
I taught my five year old how to tie an alpine butterfly with the app.
I would recommend this to anyone looking to learn knots!
