APPY NAVIGATION
Developed in Sweden, the Seapilot navigation app comes loaded with useful features. Using NOAA vector charts on this side of the Pond, the app is free to download. It comes with some useful standard features, and more clever stuff in a Premium package that requires an annual subscription. The standard app will function as a basic chartplotter, while with the Premium service you gain the ability to set up routes, download GRIB files and weather forecasts, display AIS targets and data from your instruments, track and share your voyages, and more. Available for Mac OS, iOS and Android devices. $39.99 (Premium). Seapilot, seapilot.com
