Best anchor watch

This is the best anchor watch I was able to find. It does everything you'd expect it to do. Even when you switch off your ipad (not power-off or stopping the app of course), Anchor! stays active and will wake up itself (and you) on alarm conditions.
We've been using this app on our yacht in the Meds six months a year on an almost daily basis for a couple of years. It never was unreliable (apart from a small problem in a new version).
This review was written at 3 in the morning on an anchored yacht in 30 kts winds, gusting up to 42.

Great Anchor alarm

This alarm has saved my boat when we were hit by a strong southerly. The anchor dragged and then picked up seaweed. The alarm woke us up and I was on top of it.
Easy to use with good coverage. Just set the pick and the alarm and it works with IPhone or my iPad. I leave it by the bed charging and it monitors all night. You can also set it to call you by sms if you leave the boat with iPad monitoring while you go out on your tender for a black walk. 10/10

Developer Response ,

Thanks a lot this great review :)
A precision, the remote mode needs data coverage and is not based on SMS.

Great App

Great app - used this nightly during a bareboat charter in the Whitsundays Queensland. Often didn’t have any mobile reception so couldn’t load background maps, but for the purposes of alarming if drifting beyond a radius this app was perfect. Great that it keeps running with phone screen off. Was always interesting to review the app in the morning to see how the boat had moved around during the night.
