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 Ray marine chart plotters which cost thousands of dollars. The anchor alarm function on chart plotters 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 centered 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 degree wind shift, the allowable drift range has to be extended by chain length + boat length, e.g. for 30 m chain out + 14 m boat and 10 drift, the alarm drift radius has to be set to 2x (chain + boat length) + drift = 98 m. Using the Anchor Alert app, the alarm drift radius would be chained + boat + drift = 54 m. Also, the alarm sound on the Ray marine 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.

Excellent Bought this a couple of days before my annual sailing trip thinking it would be "a bit of fun", but on the first night when it took 5 attempts to set the anchor and with winds stronger than expected it worked brilliantly and provide a great deal of reassurance. The instructions, though extensive, are not very clear, but once you get the hang of it you can effectively set a segment of your swinging arc as a zone and see your track within it. Highly recommended.
★★☆☆☆
I tried this when at anchor a few weeks ago. There was some poor weather overnight and I thought it would be a good test. Used my phone for the installation. Excellent mobile signal in the area, and good GPS/etc. coverage. First time I set it with a very small swinging circle, and it went off OK. Next time I set it with a slightly larger one, and it didn't go off all night. The following day I repositioned to a nearby harbor, and it went off about 1,000 m (1,000-yards approx) away. Not recommended.
★★☆☆☆
Works great until it does not. Way too many false alarms from the app
loosing its GPS accuracy. The monitoring stops, and I have to restart the
anchor set process. Tried for three days in windy conditions, no luck. My
plotter showed us swinging on the same arch with the anchor not moving as
did my compass shore marks. The device had a clear view of the sky, I even
left it on deck for a while, no luck. Not useful if you can't trust it.
Waking up every 2–3 hrs for a GPS failure on a windy night is no good. Will
try another app.
