Anchor Alarm for iPhone & Mac
Set a watch radius, step ashore, and get alerted the moment your boat drags — from shore, the restaurant, or your berth. Hooked is the anchor alarm built for modern sailors.
Everything you need
Watch your boat's live position from shore, the restaurant, or your berth — even miles away. Get notified the moment the alarm triggers.
Filters out low-accuracy GPS fixes to reduce false alarms. The alarm only triggers when your boat genuinely crosses the watch radius.
See nearby vessels by name on the map. Know what's around you in a crowded anchorage — before you set the hook.
Limit the alarm zone to a sector of bearings. Perfect for anchoring near rocks or in a channel where you only need to watch one direction.
Connect to chartplotters, Vesper AIS, Peplink routers, and other NMEA devices for GPS precision plus live depth, wind speed, and heading.
Review every past anchoring session — track, timing, max wind speed, and more. Resume, repeat, or cancel a session locally or remotely.
Premium Feature
Leave the boat, keep the peace. With a Premium subscription, a second device can watch the live position and track in real time — across iCloud or on the same local network. See the same map, battery level, depth, and wind data as if you were on board.
