- Adjust the radius of the wetting area by moving the green dot to the edge of the zone.

- View SailGrib WR maps.
- Import the GPX trace of SailGrib WR if you forgot to start the application before wetting.

The app runs in the background and uses the latest Android techniques to reduce power consumption while maximizing position accuracy.

Note that the accuracy of your position depends on your phone and your location. As of march 2021, we consider that most phones have an accuracy between 2 and 10 meters while at sea.

Ratings and reviews

Great application, I love that it traces the boat position on a map, while the boat is moving around at anchor. Couple problems though: it looks like it needs to have the screen on all the time and yet, the app's settings don't allow you to do this. My Samsung S24FE doesnt allow more than 10 minutes. If the screen turns off, the app eventually gives you an alarm and message that it's lost GPS fix.

App kinda works if you are on board. SMS functionality is poor. You receive a cryptic message in poor English without proper GPS coordiantes. Tried sending them e-mails from within the app and also from the computer (using the address they provide, also on their website), but only received Undeliverable messages back. Better go with something more professional.

Great UI, can't prevent lock screen from disabling it. While the map can be dragged to center it on the anchor, the distance/bearing display from boat to anchor it hard to read and only appears when zoomed way in (fill most of screen with boat-to-anchor line). Great integration with Navionics. Bugaboo with all anchor alarms in Android is their inability to defeat the lock screen when monitoring so the alarm quits monitoring as soon as the lock screen turns on.
