What's New in Anchor Alert

2.0.7

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.

Not ready for prime time

This app is pretty useless.

- Can’t adjust anchor position or radius once alert set.

- can’t set anchor position by lat/long.

- if you update the app after setting alert, you loose everything

- Records/Displays spot locations at a specified interval as boat moves at anchor. Would be nice to connect the dots and see the actual track.

… to name a few

(Big fan and user of PredictWind but this app is written to a different standard )

Frechheit. Da gibts viele andere Apps die weniger kosten und mehr können. Predictwind sollte sich schämen, durch Gier den guten Markennamen kaputt zu machen.

Hallo Chris, wir bieten eine kostenlose Version an, um Ihren Anker zu überwachen, während Sie auf dem Boot sind. Für Benachrichtigungen beim Essen oder Sightseeing an Land können Sie diese Funktion mit dem PredictWind Professional-Abonnement für 15 USD monatlich oder 99 USD jährlich ohne abonnieren. Es ist eine kostengünstige Möglichkeit, um sicherzustellen, dass Sie beruhigt sind, während Sie weg sind. Es ist die einzige App, die Ihr Boot mit Live-Daten von Ihren Instrumenten überwacht - sie verfolgt Ihre genaue GPS-Position, Tiefe, Wind und sendet Scope-, Swing-, Drag- und AIS-Alarm - Tag und Nacht, an Bord oder an Land. Hi Chris, we offer a free version to monitor your anchor while you're on the boat. For alerts while dining or sightseeing ashore, you can access this feature with the PredictWind Professional Subscription or for $15 USD monthly, or $99 USD yearly without it. This is an affordable way to ensure peace of mind while you're away. It is the only app that watches your boat using live data from your instruments - tracking your precise GPS position, depth, wind, and sending scope, swing, drag, and AIS alerts - day and night, onboard or ashore.

Simple Mode is the winner

The thing I like most is being able to drag the anchor into position and set a safe radius in about ten seconds. No fiddling with numbers when you’ve just dropped the hook and want to get on with dinner. If you want more precision later, Advanced mode is right there - but for most nights at anchor, Simple does the job and the alerts do the worrying for you.

FAQ

What does Anchor Alert do?

Anchor Alert allows you to monitor your boat's position and anchor status from anywhere using your phone. It provides customizable alerts for anchor drift and changing weather conditions, and integrates with marine weather forecasts.

How does Anchor Alert monitor my boat?

You can set your anchor position and a safe radius on a map. The app then monitors your vessel's position relative to this radius. It can be used with just your phone, or connected to your boat's N2K backbone and a PredictWind DataHub for more advanced data.

What kind of alerts can I set?

You can set up preset or custom real-time and forecast alerts. If your boat moves outside of your specified safe limits, or if conditions change significantly, you will be notified. The DataHub can read your boat's N2K network to trigger these alerts.

Can I use Anchor Alert when I'm not on my boat?

Yes, Anchor Alert is designed to work both on and off the boat. You can monitor your vessel and receive alerts onboard via the DataHub's Wi-Fi network, or stay connected over your vessel's existing internet connection when you are ashore.

Is Anchor Alert free to use?

The app is available for free download, but it offers in-app purchases. These purchases likely unlock advanced features or services, such as access to premium weather data or enhanced monitoring capabilities.
