    Description

    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 automatically takes into account the magnetic-declination of your location to more accurately set the anchor watch point. It has a clutter-free interface and runs fully off-line (after initial verification). It has been designed primarily to maximise reliability and battery life while allowing the user the greatest degree of flexibility and customisation possible.

    Some of Anchor Alerts features:
    - unique anchor projection system, just point and click and your anchor position is set
    - user defined swing area with 'touch-to-set' exclusion and slack zones
    - very low memory usage and the longest battery life in its class
    - can be set to run completely in the background while you use your phone / tablet for other things
    - can be controlled by SMS* from an authorised second phone and can be set to send SMS alerts* with embedded Google maps URLs (* on devices that support telephony only)
    - silent or audible alarms, with or without vibration
    - vessel tracking, historic location traces and more

    If you want the best anchor alarm / anchor watch for Android, you want Anchor Alert.

    See http://www.slimjimsoftware.co.uk for a full run-down of features.

    ** 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 the anchor alarm 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 Alerts background function and may cause it to be shut down after a few 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, 3.x and later than 4.0.4 should not be affected.

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

    Excellent anchor alarm app. I've used it enough to have complete confidence in it. It's easy to set up and it works. I don't understand why this functionality is not designed into Raymarine chartplotters which cost thousands of dollars. The anchor alarm function on chartplotters does not allow for setting of distance and bearing to the anchor, so unless you activate it when the GPS sensor is directly over the anchor, which is virtually impossible to do, the swing circle will never be centred around the anchor and is usually offset by chain length + boat length (assuming that the GPS sensor is towards the stern of the boat). This means that if you have to allow for a 180 gegree wind shift, the allowable drift range has to be extended by chain length + boat length, e.g. for 30m chain out + 14m boat and 10 drift, the alarm drift radius has to be set to 2x(chain + boat length) + drift = 98m. Using the Anchor Alert app, the alarm drift radius would be chain + boat + drift = 54m. Also, the alarm sound on the Raymarine eS series plotters is a rather low level 4kHz tone which is easy to sleep through. You will NOT sleep through the Anchor Alert alarm sound!! Thanks for a great app.

    This app does exactly what you need. And does it easier than any other app I have tried.

    The drift history tracking feature is not the best or very accurate. MAW is better for my purposes.

    This app has been a great way to sleep better while on the hook. With the message capabilities, even going ashore is less of a "I hope we're still in the same place" moment.

    Tried them all. Thuis is the easiest to use and most configurable. And ost importantly you don't have to set it while anchoring - easy to set later. Well worth the money.
