As a novice to coastal navigation, i have found this app to be awesome. It Works just like a chart plotter but better cause you can save screen images of your routes. I know theres pricier nav apps out there, but for 8 bucks this one is an accurate way to chart your course and see exactly where you are, speed, ETA, waypoints, and easy to use. Just be sure to download your charts before you set sail so you can access them at sea. Im still learning all it does, but so far its perfect for my Ga. Coastal navigation .... S/V Glory Days
