Cordevia Knots

Cordevia Knots is a quiet reference for the rope work you keep meaning to learn.

Twenty knots, sorted by where they live: on a boat, on the end of a fishing line, in a climbing harness, holding up a tarp, around a parcel, or coiled on a key fob for the pleasure of it. Each one comes with its purpose, a sketch of the steps, and a short paragraph telling you why it's been worth keeping around for two hundred years or so.

There are three rooms in the cabin drawer:

· Browse — every knot, filterable by category. Tap to open the step-by-step.
· Favorites — keep the ones you use. They stay there until you say otherwise.
· Silhouette Quiz — a small game. Ten outlines, four candidates each, name the knot. It remembers your best round.

The illustrations are drawn on the device — no images downloaded, no fonts fetched, nothing called home. The whole thing fits in your pocket and behaves itself when there isn't a signal.
