# iNavX vs AIS Radar

The clearest difference is review sentiment: AIS Radar at 100% against iNavX's 44%. AIS Radar also leads on in-app purchases (none vs 11) and ads (none vs shown). iNavX's advantage is price (Free vs $6.99) and rating (4.8 vs 4.0). On device support and iOS requirement there is nothing between them.

iNavX is free to download; AIS Radar costs $6.99 up front. iNavX sells 11 in-app purchases, starting at $9.99 per month. AIS Radar asks for nothing beyond the download.

iNavX holds the better App Store score, 4.8 against 4.0. That said, the two scores are not equally well evidenced: iNavX has 22K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 44% of iNavX's written reviews are positive against 100% of AIS Radar's, so the app with the better star average is not the one people write more warmly about.

iNavX ships an update every 5 weeks, AIS Radar every 7 months. The most recent releases landed on October 27, 2026 and October 26, 2026 respectively.
