AnchorSentinel is a nautical program with three primary purposes: It provides an accurate position, speed and bearing (true and magnetic) while underway, it stands sentinel against anchor drag while at anchor, and it provides an arrival alarm for a specified travel distance. AnchorSentinel relies on the fact that most Android devices have a built-in GPS receiver able to determine its position within a few meters, adequate accuracy for AnchorSentinel's purpose.
For boaters who haven't been in dangerous situations, or who don't anchor very much, I should say that an anchor watch is a very good idea, and an Android device is an ideal platform for this task because it requires very little power, it operates independently of the boat's primary navigation and power systems, and it provides a secondary source of accurate position information in an emergency.

Great The only quick to use anchor watch app that works that I have found so far and I have tried many. The distance alarm idea is great as well for voyages approaching the coastline or hazards. Captain Ian Engelbrecht - Worldwide Yacht Deliveries
Does what it says Beautifully simple - which is a great safety feature. Minimal permissions. Looking forward to using it for real. It appears to use a lot of battery, even when closed and the GPS is turned off, unless you EXIT using the EXIT option (I should have read the excellent HELP pages more thoroughly).
