Used iNavX - Sailing, Boating and Marine Navigation for iOS?
Editors’ Review
iNavX - Sailing, Boating and Marine Navigation, developed by GPSNAVX, turns an iPhone into a portable chartplotter for coastal and offshore navigation. The app plots real-time position with internal or external GPS, manages waypoints and routes, and overlays GRIB weather and anchor alarms to inform decisions. It gives mariners choice among multiple chart providers and offline charts, making it suitable for recreational sailors, tournament anglers, and professional crew learning applied navigation skills.
Top Recommended Alternative
iNavX functions as a handheld chartplotter that teaches practical navigation through route planning and position fixing. The app plots live GPS locations, lets users create, edit, and import/export GPX or KML waypoints, and supports raster and vector chart formats. Its multi-provider chart model exposes learners to different chart styles, helping sailors practice chart interpretation and cross-checking routes against alternative sources.
What is iNavX used for?
How does it develop situational awareness at sea?
By combining live instrument feeds with weather overlays, the app trains users to interpret environmental and vessel data together. It accepts NMEA over Wi‑Fi to display depth, speed, and wind, plots AIS targets with proximity alarms for collision awareness, and displays GRIB forecasts for wind, pressure, and temperature. These elements let learners practice real-time decision-making and risk assessment in changing conditions.
Is it suitable for recreational and professional mariners?
The app targets both recreational sailors and professional crews by offering advanced configuration and multiple chart vendors. It runs on iPhone and iPad and navigates offline after charts are downloaded, relying on device GPS. Chart updates can be managed across linked devices, though transfers depend on provider licensing. Expect a learning period because many settings expose professional-level controls for instrument and chart presentation.
Pros
- Supports multiple chart providers, including Navionics and NOAA
- GRIB weather overlays show wind, pressure, and temperature
- Integrates NMEA and AIS data over Wi‑Fi for real-time displays
Cons
- Advanced settings create a steeper learning curve for new users
- Chart transfers between devices can be restricted by provider licensing
- Requires iOS 13.0 or later for Apple devices
Bottom Line
Best fit for hands-on learners who accept a technical learning curve
iNavX is a practical option for mariners who want to build navigational competence through active, on-deck practice. Its depth rewards users willing to invest time, so expect a setup and familiarisation period. For training, simulate short coastal passages and regularly practice tasks in sheltered waters to build confidence before extended outings. It suits crews aiming for applied, skill-based navigation training.
