This marine navigation app is the easiest & amazingly totally free! Give it a try, I know you’ll agree the ease of use and clean interface will meet your needs.
Everything I really wanted for a simple GPS-based smartphone app with nautical chart integration. Highly recommend!
Love the app! Easy to learn, visually clear with several layout options for customizing info, terrain views, etc.
I love the intuitive autorouting function and my wife enjoys the social/community features for connecting with other boating friends.
My father takes very frequent trips on his boat for the past 5-6 years and I showed him this app a few days ago & he LOVES it. He hasn’t stopped using it.
It’s straightforward, uncomplicated, has a clean interface/display that isn’t overloaded, is easy to learn, and performs reliably.
This app needs to be in every boaters arsenal. I absolutely love it. What a service the creator has done for us and for FREE!
