Monitor your boat from anywhere on your phone. Set alerts & monitor your boat at anchor, view live N2K data and weather forecasts, on or off the boat. Customise your alerts, then relax knowing your boat is in good hands, with Anchor Alert.
* Monitor your Anchor and Boat Position - Set your anchor position and preferences in quick or advanced mode, then monitor your vessel and position history on the map. Can be used with just your Phone or connected to your N2K backbone and a PredictWind DataHub.
* 3 Modes, Simple, Advanced or Datahub linked - Use Simple Mode to quickly drag the anchor into position and set a safe radius. Advanced allows you to manually enter data for increased accuracy. DataHub Link reads your N2K data and fills in the relevant info, then input how much chain you’ve let out, and you’re done!

* Works On & Off The Boat - Monitor your vessel and receive alerts onboard via the DataHub’s Wi-Fi network, or head ashore and stay connected over your vessel's existing internet connection. The DataHub is compatible with the Iridium GO! exec and other satellite connections to keep you connected literally anywhere on earth.

Latest updates
2.0.7
New Features
- App setup requests Local Network permission so that Starlink / Peplink and Other Wi-Fi users' Anchor Alert app can find the DataHub the first time they start monitoring through any Wi-Fi network other than DataHub Wi-Fi.
- Settings > DataHub Connect > new field "Login Status" - this field shows you whether Anchor Alert has logged into DataHub successfully or not, separately from NMEA Connection Status. This way, if the Wi-Fi radio bars on the Anchor Map top left are red/disconnected, you can clearly see whether this is because of an issue with the NMEA feed or the DataHub app login.
Default Setting Change
- Anchor Alert Settings > Map View Type > Hybrid. Changed from Satellite View because it adds local place names, which is more useful than the standard Satellite View.
Other minor bug fixes.
