Anchor Sentry

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 setup perimeter. Features: - Show current position on GoogleMaps map or Navionics map (To gain access to Navionics maps from this application, users with an active Navionics subscription in the Navionics Boating application must register with their Navionics credentials) - Distance circles to help finding a good anchor position - Drop anchor by tapping on map or by position or by bearing and distance - Can be used for anchoring with shore lines by watching the heading rather than the position - Tracks can be saves as GPX file for later processing - 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 - Barograph function included - Display real echo sounder data from a providing NMEA server - Optional compass overlay to help finding the bearing to the anchor - 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. - Automatic anchoring feature - Display maximum swinging circle - Save favorite anchoring places with pictures - Several setup options to customize your app

- Added a new optional setting Show picker in dialog to choose between the previous in-cell pickers scrolling to change values in the settings and a larger picker dialog. - Added dedicated position filter settings (master filter, speed filter, distance filter, distance threshold and time delay) in a separate filter settings page. - Updated position processing to use the new filter options for speed and distance jump handling. - Added Posidonia support in exclusion zones: Posidonia polygons can now be downloaded from Spanish authority data for the currently visible sea area and stored as zones. - Posidonia zones are shown on the map for orientation but do not trigger alarms. - Mirroring: Fixed a connection recovery issue when switching from onboard Wi-Fi to cellular data (e.g. LTE). The receiver now reconnects the WebSocket link more reliably. - Proximity alert/mirroring: When transmission is stopped while the server connection remains active for the proximity alert, the connection is now kept in proxy mode correctly and no longer restarts normal transmitting after a later reconnect.
