The original
Argo
A marine navigation and trip planning app with nautical charts, autorouting and a boaters' community.
Replacements
Listings that take over the same core job as Argo.
Aqua Map
A marine navigation app for boaters that shows NOAA, USACE and CMOR charts with offline use.
Aqua Map uses NOAA, USACE and CMOR charts offline with an anchor alarm, but lacks a web version and centres on US waters and the Bahamas.
Savvy Navvy
A boat navigation app with marine charts, tides and weather, pitched as Google Maps for boats.
Savvy Navvy plans routes that account for wind, tide and current in a simple phone interface for less experienced boaters, with advanced features on subscription and no web version.
iNavX
A marine chartplotter app for iPhone and iPad with charts from many providers, AIS and GRIB weather.
iNavX acts as a handheld chartplotter with more than 25 chart providers, live AIS, GRIB weather and instrument overlays, with commercial charts from other providers sold separately.
Seapilot
Marine navigation app with digital nautical charts, AIS, routes and weather routing.
Seapilot offers AIS, NMEA sensor support and GRIB weather routing in its Premium tier, and charts cost extra outside the US.
OpenCPN
A free, open-source chartplotter and marine GPS navigation program for laptops and onboard computers.
OpenCPN is free and open source for Windows, macOS, Linux and Android, built for use at the helm on a laptop or onboard computer, with some charts obtained separately.
Also worth comparing
These listings name Argo as their own alternative, so the relationship runs both ways.
Navily
A cruising guide app for finding anchorages and marinas, with community reviews and slip booking.
Argo combines crowdsourced marina reviews with nautical charts, forecasts and trip planning, with autorouting and some features in paid plans.
OpenSeaMap
Free community nautical chart built on OpenStreetMap, with seamarks, harbours and depth data.
Argo includes nautical charts in its free plan on web and mobile, with offline charts and crowdsourced reports, but it is a proprietary service rather than community-editable chart data.
Orca
A marine navigation app for planning trips with charts, routing and weather, with optional boat hardware.
Argo adds a web version, crowdsourced marina reviews and a free plan with charts and manual routing, while autorouting sits in paid plans.
