My navigation app
This has been a great app for me on the Great Lakes. It is my navigation instrument on iPad and iPhone. It is great at anchor and everywhere else. It also supports Navionics vector charts. It supports waypoints, routes, weather data, and with my Digital Yacht AIS, it also displays all my instruments data from my NMEA 2000 network. It also displays the AIS info, of course.
