About
iNavX is the leading handheld chartplotter application for iOS, recognized by Practical Sailor as an 'Editor's Choice Winner' and praised by Cruising Magazine as 'The Standard.' Designed for sailors, fishermen, and cruisers of all experience levels, iNavX transforms your iPhone or iPad into a fully featured marine navigation system. Upon download, users automatically receive complimentary high-resolution NOAA RNC raster charts covering the US West Coast, Gulf Coast, East Coast, Great Lakes, Alaska, Hawaii, and the US Virgin Islands. Beyond free government charts, iNavX offers access to an extensive In-App Chart Store featuring charts from leading hydrographic offices and cartography companies including Blue Latitude, Explorer, Waterway Guide, and Delius Klasing. Key capabilities include real-time GPS position plotting, seamless chart panning/zooming/rotation, waypoint and route creation, track logging, and data import/export in KML and GPX formats. The app also supports NMEA data over TCP/IP, integration with external GPS and AIS receivers, and connectivity to onboard instruments for depth, speed, wind, and engine data. Additional tools include GRIB weather forecasts, tides and currents, anchor alarm, AIS alarm, and port/navaid search. iNavX is ideal for anyone seeking a reliable, feature-rich backup or primary chartplotter at a fraction of the cost of dedicated hardware.
