# C vs NaAVIC

The clearest difference is rating: NaAVIC at 5.0 against C's 4.5. NaAVIC also leads on in-app purchases (none vs 11) and iOS requirement (12.0 vs 15.1). C's advantage is ratings volume (2.3K vs 1) and update cadence (every 6 weeks vs every 6 months). On price, ads and device support there is nothing between them.

Both are free to download. C sells 10 in-app purchases, starting at $1.99 per month. NaAVIC asks for nothing beyond the download.

NaAVIC holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: C has 2.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 51% of C's written reviews are positive against 33% of NaAVIC'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, NaAVIC every 6 months. The most recent releases landed on October 17, 2026 and October 1, 2026 respectively.
