Description
Anchor Alarm - The anchor guard for your boat
Get alerted as soon as your ship aborts.
Set the radius and click on Start to start the anchor alarm.
As soon as your ship leaves the radius, your device alerts you with an unmistakable alarm tone.
In addition, you can move the monitored area and correct it to the nearest meter.
The location history of the boat is recorded and can be seen from the small points.
With our remote monitoring feature, you can connect two devices together.
The sender remains on the boat while you are on land.
As soon as the sender leaves the area you will be alerted on the way.
(stable internet connection required)
With our anchorage search, you can search for anchorages in your area where other crews have anchored before. Try this module for free for 3 days!

Ratings and Reviews
Good nights sleep
I used the app every night with the Leopard 4000 between Antigua and Barbuda. It is simple and intuitive to use, easy to adjust, and works consistently as your GPS signal which was usually 6 feet. Slept better on board than I do at home with the security of this app
Simple to use, but doesn’t stay on.
I love the simplicity. However, the app does not get priority in the iOS to stay functional when other programs are running. Several of the past days it has been running as expected, then when returning to check on the anchor track after being on other programs, the track is gone and I need to place the marker and guess where the anchor is on the map and adjust over time as the boat moves. Not a good thing when you want to go to sleep.
Works good
Wish alarm was louder when triggered but it’s on a phone sooooo…
