# iNavX vs VesselFinder

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.

Both are free to download. iNavX sells 11 in-app purchases, starting at $9.99 per month. VesselFinder asks for nothing beyond the download.

iNavX holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 232, so its average is the more settled of the two. Written reviews point the same way: 44% of iNavX's written reviews are positive against 28% of VesselFinder's.

iNavX ships an update every 5 weeks, VesselFinder fortnightly. The most recent releases landed on October 1, 2026 and September 28, 2026 respectively.
