We love this anchor app and really want to give it five stars. As full time cruisers that were at anchor for two years straight in the South Pacific this was our go to anchor alarm. It has as the bells and whistles that are important to us. In 90% of the cases we’re satisfied with the free version. In rare instances we want the premium features and at a price of $25 for the year we felt it was worth it. We subscribed in March, but unfortunately we have not been able to unlock the premium features. A couple times over the past nine months we wanted to access premium features, unable to do so we reached out to customer support (at least twice) and our message fell into a black hole and there was no response. It’s possible it’s user error on our part (what email did we use? It was so long ago!), but we can’t work that out without getting a response back from Zenkou.Again, this is a fantastic anchor alarm, even at the fee base version. We just wish we could contact support.

Once I had the iPad broadcasting to the IPhone, the alarm worked perfectly, somehow with more accuracy then the Chartplotter on our boat. We traveled far from the boat due to this app, knowing it would alert us if the boat moved beyond a user set distance. I highly recommend this for an anchor alarm.
