Fog Horn

Out with the boat and the fog comes, what signal was it again when I’m sailing?

No worries, this app will give you an audible reminder every two minutes and the correct signal when you are sailing or going by engine.

The reminder to give signal will also work while the app is in the background so you can use your device for other tasks.

Never forget the most important audible signals while at sea, all explained in the help section.
