Vigia - Anchor Watch
Anchor drag alarm & wind
$2.99 · Designed for iPad. Not verified for macOS.
Sleep easy at anchor. Vigia learns your swing circle and raises the alarm the instant your boat drags — with a 24-hour wind forecast at your mooring.
Vigia keeps watch over your anchorage so you can relax — at anchor, on deck, or asleep below.
Mark your anchor and Vigia draws a guard circle on the map. If your boat leaves it — the anchor is dragging — a loud alarm sounds, even with the silent switch on and the screen off.
What makes Vigia different
• Learns your swing circle automatically — no rode length to enter; it watches the boat swing and works out the real pivot and radius.
• Smart alarm — guards against a single bad GPS fix, and only widens the circle on a genuine swing, never on a drag.
Wind at your mooring
• 24-hour wind forecast at your anchorage: wind, gusts, direction + an hourly graph.
• Set a gust threshold — hours above it turn red, so you see the blow coming.
Built for a night at anchor
• Background watch, screen off; adaptive GPS (dense while learning, easy on battery afterwards).
• Selectable alarm tones, audible over the silent switch.
• Recenter on the real pivot; pause when you go ashore; clean stray track points in one tap.
• Hand the watch off to another iPhone over AirDrop.
No account, no API key. Wind data by Open-Meteo.
Important — Vigia is an aid, not a substitute for a proper watch. It carries no nautical charts and cannot see hazards. The safety of the vessel and crew remains the sole responsibility of the skipper. Use at your own risk.
