Argo is a boat navigation app you can actually use for free. Not a trial. You get NOAA charts and U.S. Army Corps of Engineers depth surveys for US waters, 500,000+ marinas, anchorages and fuel docks, hazards reported by other boaters, and routes you plot yourself, with ETA and fuel use. On your first trip, open the map to see how deep it is and read what other boaters say about the anchorage before you drop the hook. A hundred trips in, you're checking how old the Army Corps survey is before you run a shoaling inlet, or laying out a few route options and picking one underway. Think of Argo as the boating buddy who knows every good dock bar and never asks for gas money.

WHO'S BEHIND ARGO Argo is family-owned. Our founder, Captain Jeff, grew up boating on the Chesapeake Bay. He built Argo so the local knowledge usually shared between friends at the dock is on the map for everyone. Many of our features started as boater requests. Send yours to support@argonav.io. Argo is a navigation aid. Always check official charts and conditions, and use your own judgment on the water. Plan. Navigate. Connect.

Verdict
iNavX and Argo Navigation both sit at 4.8 stars, but that hides the real split: 84% of Argo Navigation's written reviews are positive against 44% of iNavX's. Argo Navigation also leads on ads (none vs shown) and update cadence (every 4 days vs every 5 weeks). iNavX's advantage is ratings volume (22K vs 6.2K) and iOS requirement (13.0 vs 15.1). On price, rating, in-app purchases and monetization model there is nothing between them.
