AnchorGood

Sleep at anchor with an extra pair of eyes. AnchorGood watches your boat's GPS position and sounds a loud alarm on this phone if the anchor drags.

AnchorGood watches your boat while you are at anchor and sounds a loud alarm on this iPhone if the boat leaves the circle you set.

DROP ANCHOR IN FIVE STEPS Check GPS readiness, mark the anchor where it went down, enter water depth and rode, confirm the suggested alarm radius, and arm the watch.

A CLEAR ALARM • Loud alarm with vibration and a Time Sensitive notification • Full-screen alarm with distance, limit and drift speed • Hold to acknowledge — monitoring continues • GPS-lost warning when the position cannot be trusted • "Watch stopped" notification if the app is swiped away

KEEPS WATCHING • Works with the screen locked and in the background • Works without internet — only the weather needs a connection • Live distance to the anchor and to hazards you describe

MORE ON BOARD • Wind, gusts, waves and swell for your anchorage • Scope and swing circle from your boat and rode • History of past anchorages with their track • Call, text or WhatsApp your safety contacts in one tap from the alarm screen — you send the message • Night Watch display that protects your night vision

PRIVATE BY DESIGN No account, no ads, no tracking. Your boat, contacts and anchor watches stay on your phone.

IMPORTANT AnchorGood is for information only. It does not replace official nautical charts, a chart plotter or other primary navigation equipment, a proper anchor watch or good seamanship, and the skipper remains responsible for the boat. It needs "Always" location and the phone should be kept charging during a watch. Weather data by Open-Meteo.com.
