A free app for Android, by wellenvogel.
With the latest version of AvNav, you can enjoy a new experience on your mobile devices, using electronic raster charts. The application displays the maps on your screen and allows you to navigate your boat with ease, even in the most difficult spots.
The app has a built-in GPS and allows you to use the device to obtain the coordinates of your points of interest, and create and store routes to be used later. In addition, it has a built-in AIS (Automatic Identification System) that allows you to receive information about the vessels that are nearby.
The app is also capable of sending and receiving messages to/from other devices via a wireless connection.
