With Navi you will be able to identify other boats at night by their navigation lights.

You will also distinguish the different types of buoys and markings, by their colors and lights.

In addition, you have a complete description of the International Maritime Code Flags.

You can configure Navi to display buoys based on the region you are in (IALA System A or B).

If you're on a night navigation, you can also use the app in dark mode.

Navy is a very useful sailing app, always available without internet connection, and totally free of annoying ads.
