If you want the best, you want Anchor Alert.

Anchor Alert is an advanced anchor alarm application made by a professional software developer and MCA certified Yachtmaster. It was the first anchor alarm available for Android devices and remains the number one choice of serious boaters. It uses a unique anchor projection algorithm which takes into account the magnetic declination of the current location to more accurately set the anchor point. It has a clutter-free interface and once initial verification has taken place runs fully off-line. It has been designed primarily to maximise reliability and battery life while allowing the user a great degree of flexibility and customisation.

** GPS accuracy and performance depends on your phone's hardware. Please read the help page fully and make sure you understand how to tell if this application is running in the background and how to completely stop it.

NOTE: some Android devices using versions 4.0 to 4.0.4 are known to be overly aggressive when shutting down background tasks, this interferes with Anchor Alert's background function and causes it to be shut down after a couple of hours without warning. if you own one of these affected devices please contact your carrier about an upgrade to 4.0.4 or later, in the meantime you should only use foreground mode. Android versions 2.x and 3.x should not be affected.

Finally, please email me and let me know how I can make this app better for you before leaving negative feedback. My goal is a 5 star rating from everyone that buys this app, please help me achieve this!

    Don't think twice about having to pay for this app. It's the best app for sailors that has been developed. It certainly worked for me and alerted me to a potentially disastrous situation for which I am eternally grateful. Works better than my Garmin! I notice my original story appears on the website so I won't repeat it here. One thing that is interesting is that although I have a steel boat

    You must have this if you anchor your boat and can't stay on deck to be sure you stay put. Sleep soundly or go ashore for the day and know the boat is where you put it.

    I used this app sailing in the San Juans last summer. I am a fairly novice and paranoid sailor, but using this app allowed us to have an amazing week. Using this app we were able to anchor in some very tight conditions in weather. There was one night where the app detected us dragging the achor in a tight anchorage with other boats. Without this app, our sailing trip would have: a) not been pos
