Most Valuable App you could own
I have had this app for sometime now, and it has been more handy than any other. It is easy to use, and has helped me more than once. Knowing knots is something everyday be should know, especially preppers, campers, hikers, etc.
This app has five stars for ease of use, and usefulness!
