Professional-grade navigation, anywhere you boat. iNavX gives you worldwide charts, route planning, live AIS, and GRIB weather in one app — the power tool that makes you a more capable, more confident captain.
For boaters who want more control than a basic GPS app — and more flexibility than a dedicated chartplotter.
One coastline, one vendor, no depth. Fine until it isn't.
Thousands of dollars, bolted to one boat, updated rarely.
Every chart provider, every device you own, full pro control — for the price of a paper chart.
More control than a basic GPS app. More flexibility than a fixed chartplotter. Here is how iNavX makes every passage safer and more confident — one screen at a time.
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.
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.
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.
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.
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.
Start with free NOAA raster charts for US waters, then add premium charts from the world's leading hydrographic publishers — all inside one seamless in-app store.

Plot your live GPS position on high-resolution raster and vector charts. Pan, zoom, rotate, and read depth at a glance — with real-time instrument overlays.
Build waypoints and multi-leg routes, watch bearing and distance update as you sail, and keep a full track log you can export anywhere.
Turn your phone into a repeater. Stream NMEA data over TCP/IP, connect external GPS and AIS, and mirror your MacENC helm.
GRIB weather, tides and currents, anchor and AIS alarms, port search, and a searchable history — the everyday tools that keep you safe.
The most complete marine navigation app you can put in your pocket — a genuine chartplotter, not a toy.
iNavX has become the gold standard for tablet and phone navigation among serious cruisers.
For the price of a paper chart, you get a navigation suite that rivals dedicated hardware.
"I race offshore and iNavX is the only thing on my phone I trust for backup navigation. Waypoint export to my crew is instant."
"Replaced a $2,400 chartplotter on our cruising cat. NOAA charts, GRIB weather, anchor alarm — everything we need in one place."
"The instrument repeater over NMEA is flawless. I have wind, speed, and depth at the helm and again below at the nav station."
Still have questions? Our support crew is standing by.
Every new user receives high-resolution NOAA raster charts covering the US West, Gulf, and East coasts, the Great Lakes, Alaska, Hawaii, and the US Virgin Islands — at no cost.
iNavX runs on iPhone and iPad, and on Android phones and tablets. Charts and routes sync across the devices on your account.
Yes. iNavX streams NMEA 0183 and 2000 data over TCP/IP and connects to external GPS, AIS receivers, and instrument networks — including as a MacENC helm repeater.
Absolutely. Charts are downloaded to your device and your GPS fix works fully offline, so you stay oriented far beyond cell coverage.
