In addition, you can use one of the two devices to remotely monitor the other. All alarms also run in the background and when the iPhone is locked. This way, you can monitor whether one of two anchors (stern and bow anchor) is no longer holding and the ship is turning. There is an alternative monitoring option with which an alarm is triggered if your ship (or your iPhone) turns a predetermined number of degrees. A loud alarm tone also comes on when the device volume is low or off False alarms caused by individual bad GPS signals can be filtered out You can also optionally mark the anchor on the map The track during swinging is drawn on the map, so you can see at a glance when the situation changes Your ship's dimensions are shown to scale on the map An alarm tone that you won't miss (after the first opening of the app, a less obtrusive tone is configured so that you don't get too startled during your first tests) Individual shapes as swing circles instead of just round circles Here's an overview of all the important features: I have addressed and solved this problem with this app. For example, you have enough space to the south or north. Because the wind, for example, is coming from the west, but it will turn to the east at night, and maybe there is a shallow water area that you want to be warned about early on. You will surely know the problem when you want to set an anchor alarm after anchoring, you don't want the same warning distance in every direction. Now I have completely overhauled everything in Version 2, and I am convinced that your anchor watch will run differently with this anchor alarm app in the future.

More and more features were added over time. (I would never wake up from the quiet, one-time alarm tone of my Garmin GPS handheld device)Īnd that's exactly what I already implemented in the first successful version of this app. I want to be really woken up by an alarm when the anchor is dragging.

The swing circle should not be just a circle, but should take into account my individual free space, which can be different in each direction.Ģ. I had two simple requirements for an anchor alarm app:ġ.
