What you can do

Become a more capable boater.

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.

01 Your 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

02 Arrive 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.

  • Multi-leg route builder
  • Bearing & distance per leg
  • GPX / KML import-export

03 See 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.

  • Live AIS targets
  • CPA / TCPA alarms
  • Vessel detail on tap

04 Decide 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.

  • GRIB wind & wave
  • Tides & currents
  • Route weather routing

05 Beyond 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.

  • Charts stored on device
  • Full offline GPS fix
  • Nothing to lose at sea

Pro-grade under the hood

The control serious captains expect.
