More control than a basic GPS app. More flexibility than a dedicated chartplotter. Here is everything iNavX puts in your hands — one capability at a time.
01Your helm, in your pocket
Turn your iPhone into a chartplotter.
Live GPS on high-resolution NOAA and vector charts, with instrument overlays reading speed, heading, and depth. Everything a $2,000 dedicated plotter does — in the device already in your pocket.
Live GPS positioning
Raster & vector charts
Instrument overlays
02Arrive with a plan
Plan your next route.
Build multi-leg routes at the dock, check bearing and distance for every leg, then follow turn-by-turn guidance underway. Export to your crew or import a track you already trust.

03See and be seen
Navigate with AIS.
Overlay live vessel traffic on your chart, watch closest-point-of-approach and time-to-CPA update in real time, and get alerted before a situation becomes a risk. Confidence in fog, traffic, and night passages.

04Decide before you leave the dock
Know the weather before you go.
Download GRIB forecasts for wind, waves, and pressure, and read tides and currents for your exact position. Make the go / no-go call with real data — not a hunch.

05Beyond cell coverage
Navigate offline.
Charts live on your device and your GPS works with no signal at all — so you stay oriented miles offshore, in the islands, or anywhere the bars run out. The tool you can rely on when it matters most.

Full offline GPS fix
Nothing to lose at sea
Pro-grade under the hood
The control serious captains expect.
