Captain Current vs iNavX
iNavX is the veteran of marine navigation apps — a full chartplotter replacement with professional charts and live NMEA instrument data, built for serious cruisers and racers. Captain Current is built for a different moment: the night before, when you are deciding whether the trip is worth it.
Where iNavX shines
- •Free official NOAA raster charts plus a ~50-country professional vector catalog
- •Deepest NMEA 0183/2000 instrument integration of any consumer app (30+ live parameters)
- •Anchor alarm and AIS proximity alarms
- •Fully offline charting — trusted as a backup chartplotter since 2008
Where Captain Current shines
- •A recommendation, not raw data — GO / CAUTION / NO-GO with the reasoning shown
- •Best time windows and a 7-day fishing forecast with per-day scores
- •Fishing-specific intelligence: SST, chlorophyll, reports, species analytics
- •Modern, simple UX — no manual required

Why Captain Current
Chartplotter apps hand you data and expect you to interpret it — a professional reviewer needed the manual just to plan a route. Captain Current hands you the answer: a scored GO/CAUTION/NO-GO with the reasoning shown, best fishing windows, and the SST/chlorophyll layers no chartplotter app carries. One flat price, everything included, running in minutes instead of a learning curve measured in evenings.
iNavX: free app + chart subscriptions $9.99–$199.99/yr per region, weather and AIS sold separately. Captain Current: free tier, Captain Pro $9.99/mo or $99/yr, everything included. Prices last verified July 2026.
