Very Good I held off buying this because of the price for months. When we launched the boat in the spring, I realized that while expensive for an app, this was a negligible boat expense, especially for the peace of mind. I used it 15 to 20 times over the 2011 season and once I had it figured out found it very useful. When I first installed it, it would not function correctly. I emailed the developer, and he responded a couple of days later with an update that fixed my specific issue. When I first started using it, I'd anchor the big boat in a quiet cove and get into the dinghy to practice using Anchor Alert and to see how it reacted. I'd row up to a lobster bouy and set my imaginary anchor, set Anchor Alert then drift away while I could watch the screen to see when an alarm was triggered. I also tested the exclusion zones & drift. I trust the software, and while at anchor I like to use this as another tool to check my night observations.

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.

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.

Tried for 8 nights on three occasions and two different phones. Finally gave up. It seems to work great until you fall asleep, then it will generate a false alarm or GPS error and wake you up. Then you have to reset the application. Like clockwork a couple of hours you'll get another false alarm. The anchor itself was fine each time. Seems worse in windy conditions with boat swinging.

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.
