# C vs CoNav

The clearest difference is price: C at Free against CoNav's $6.99. C also leads on rating (4.5 vs 4.0) and ratings volume (2.3K vs 6). CoNav's advantage is in-app purchases (none vs 11) and review sentiment (83% vs 51%). On ads and iOS requirement there is nothing between them.

C is free to download; CoNav costs $6.99 up front. C sells 10 in-app purchases, starting at $1.99 per month. CoNav asks for nothing beyond the download.

C holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 6, so its average is the more settled of the two. Written reviews complicate that: 51% of C'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.

C ships an update every 6 weeks, CoNav every 3 weeks. Both last shipped on September 23, 2026.
