CoveGuard – Anchor Alarm

CoveGuard is an anchor alarm and sailing weather app built by sailors. It watches your anchor while you sleep, shows how the wind will blow in every bay and warns you before things go wrong — in the Adriatic (Croatia, Montenegro), Greece, Italy, France, Spain and the Atlantic, even without signal.

⚓ ANCHOR WATCH
• A zone from your chain length and depth — or draw it to fit the shape of the bay.
• The anchor drag alarm sounds only when the boat really leaves: two reliable positions outside the zone. A single GPS jump won't wake you.
• It rings like an alarm clock — even with the phone muted and the screen locked.
• If GPS drops out, it doesn't stay silent: it tries to recover the position and lets you know with a gong or the siren.
• Remote watch (Konoba): a second phone on the same account sees the boat live and gets alerted, even if the boat stops reporting its position.
• In the morning you see what the boat did overnight: the track, how far it swung and how the pressure went.

🌬 WEATHER
• The most detailed model for every sea: ALADIN-HR 2 km for Croatia, ICON-2I 2 km for Italy, AROME 2.5 km for France, Corsica, Sardinia and Spain, plus ICON-EU, ECMWF and GFS. Automatic mode blends them.
• Gusts straight from the model, waves, radar, satellite rain and lightning from space.
• All models in one chart — and how they did against what weather stations measured.
• You see how old the forecast is. Without signal it shows the last one downloaded.
• Tides and currents on the Atlantic and in the Channel.

🔔 WARNINGS AHEAD OF TIME
The server watches the weather around you every 5–15 minutes, even with the app closed:
• the wind will swing into the bay • it will blow harder • wind from the open side
• a bora is coming • a storm is approaching on radar
• pressure is falling — measured by your phone's barometer, even without signal

🏝 ANCHORAGES AND PLACES
• 16,515 anchorages and bays with a shelter score that changes with the forecast.

SAFETY IS NEVER PAID FOR
The anchor watch, remote watch, distress tools, man overboard and weather warnings are free — and will stay free.

The app is in English and Czech.
CoveGuard is an aid, not a replacement for navigation. It doesn't replace official nautical charts, VHF or the skipper's judgement.
