There is no shortage of knot-tying applications available for handheld devices and they can be a handy guide to remind you how to tie less well-known knots. Some are geared more towards fishing or climbing, but many applications include knots that sailors will use.
Knots 3D gives excellent descriptions of knots and their usage, including some history. There are no step-by-step instructions provided, but there are some notes on knot structure that can be helpeful. Animation shows the knot being tied very quickly and then you swipe your finger to see it step by step.

The weather’s been bad, and all I’ve been doing is sitting at home and practicing my knots. Is there an app for that?
We’ve come a long way from the days of books with hard-to-follow illustrations. The new apps use 3D animations and high-definition videos to show you how to tie the toughest entries.
The designers have put a real effort into modeling each knot in 3D. With Knots 3D, you can run your finger across the screen to scrub forward and back on animations, and read well-written descriptions of each entry. Sections describe the reliability of each knot, and even give an account of its history.
