GPS anchor watch
Sea miles ahead of every other anchor watch.
A real swing circle from depth and chain — not a GPS bubble. Scatter held so a still boat stays still. Wind, waves, and chart notes at the hook. Alarms on iPhone and Apple Watch.
iPhone, iPad, and Apple Watch
The circle is real
Depth, bow freeboard, and chain build the swing. Most apps drop a radius on GPS and stop there.
The boat does not walk
GPS scatter is held, so a still phone does not look like you are dragging.
The night does not go quiet
Wind and wave forecast at the hook, optional weather alarm, chart notes, siren on the phone and haptic on the wrist.
FROM THE COCKPIT
Depth, chain, and a ring you can see
Enter depth, chain, GPS-to-bow, and a safety margin. Anchorwatch shows scope, how far you should be lying, and where the alarm sits.
Start after you are lying to. The radar holds GPS scatter so a still phone does not look like the boat is walking.
The same circle on the chart
Switch to the map when you want the hook on the coast. After the boat has had time to swing, the track can confirm the hook or shift it.
Later it looks for a walking centre or a straight path. You get a warning, and the circle stays put.
Alarms that stay with you
The iPhone can sound if you leave the safety ring, if the boat swings through a wind shift, or if forecast wind and waves deteriorate.
Pair an Apple Watch if you want a haptic alarm without opening the Watch app. A Live Activity can stay on the lock screen.
Wind and waves
Open-Meteo forecast before you start. Optional banners or the same siren if conditions rise after you drop.
Chart notes
OpenSeaMap restrictions, harbours, and soundings at the hook. A missing note is not permission to anchor.
On your devices
History, depth, and settings stay on the phone and Watch. Nothing is uploaded to the developer.
Take it aboard
iPhone, iPad, and Apple Watch. Set Location to Always so the watch can keep going with the phone locked.
