## What is EH Anchor Alarm?

EH Anchor Alarm is the reliable anchor alarm / anchor watch app for sailors.

Developed by liveaboards in the Mediterranean, the app is built for real anchoring situations where your phone should keep monitoring while you sleep, rest or leave the ship.

EH Anchor Alarm alerts you even when the screen is locked if your ship leaves a freely defined anchor zone.

Create your anchor zone directly on the map, adjust it flexibly and monitor your ship’s position over time. A heatmap shows how your boat has moved inside the anchor zone, helping you understand swinging patterns, current, wind shifts and holding behavior.

EH Anchor Alarm also includes a wind alarm to monitor ship movement within the anchor zone, plus a 12-hour Open-Meteo wind forecast for your anchorage. Remote monitoring is supported with the additional EH Monitor App also 100% free.

Key features:

* Anchor alarm / anchor watch with background monitoring
* Alerts even with the screen locked
* Freely defined anchor zones
* Simple drawing and flexible adjustment of the anchor zone
* Heatmap showing vessel movement over a longer period
* Additional wind alarm for movement inside the anchor zone
* 12-hour Open-Meteo wind forecast at your anchorage
* Remote monitoring with up to 5 EH Monitor apps

EH Anchor Alarm will always be 100% free, with no ads and no tracking — from us for you.
