Wind Anchor.

A GPS anchor watch and drag alarm for boats. It calculates your true swing radius from chain scope and catenary sag, then watches your GPS position against it — with offline maps, a live swing-history timeline, and a paired boat-watch / shore-watch mode so someone back on land can keep an eye on the anchor too.
