What’s new
Version 2.0.7 · Updated September 17, 2026
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.
