App Store page →How to choose
If you go offshore or into unfamiliar waters you need charts with depths: C-MAP, Aqua Map, Savvy Navvy, iNavX and i-Boating have them, like Navionics. If you go out for the day along the Mediterranean coast, what matters more is the sea forecast, your own spots and getting there: that is Scirocco's job. Navily is the add-on for choosing where to stop.
The only boating app you need
Marine forecast, waypoints, compass, GPS tracks, boat management, maintenance and documents.
