Verdict

The call

The clearest difference is price: Aqua Map Boating at Free against CoNav's $6.99. Aqua Map Boating also leads on rating (4.7 vs 4.0) and ratings volume (14K vs 6). CoNav's advantage is in-app purchases (none vs 17) and review sentiment (83% vs 64%). On ads there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Aqua Map Boating holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Aqua Map Boating has 14K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 64% of Aqua Map Boating's written reviews are positive against 83% of CoNav's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Aqua Map Boating ships an update every 6 days, CoNav every 3 weeks. Both last shipped on September 25, 2026.
