Full description

Anchor Sentry is an app to monitor the ship's position at anchor and inform the skipper when the anchor is dragging and thus the ship leaves the speicified perimeter. Features: - Show current position on GoogleMaps map, Open Sea Map or Navionics - Distance circles to help finding a good anchor position - Drop anchor by tapping on map or by position or by bearing and distance - Option to set up prohibited zones which will trigger an alert when entered. These can be used indepent of the anchor state - Runs in the background even while other apps are used - Unique sync functionality which allows to pair two or more devices together to see the ships position even while out to shore for dinner - Option to show current position visible to friends and family on the Anchor Sentry website - Proximity alert between ships both using Anchor Sentry. To get warned when your neighbours anchor is dragging. - Several setup options to customize your app

What's new

This update improves the reliability of positioning and anchor watch: location now relies exclusively on GPS instead of sometimes-inaccurate cell/WiFi positions, an unnecessarily high background memory footprint has been fixed, and several rare crashes are resolved. New: the app now points out missing location or battery settings at startup, and can optionally warn if no GPS position has been received for a while.
