Verdict

The call

The clearest difference is rating: iNavX at 4.8 against VesselFinder's 4.1. iNavX also leads on ratings volume (22K vs 232) and review sentiment (44% vs 28%). VesselFinder's advantage is in-app purchases (none vs 11) and update cadence (fortnightly vs every 5 weeks). On price, ads, monetization model and chart position there is nothing between them.
