# Nerva vs CanXida

The clearest difference is rating: Nerva at 4.7 against CanXida's 3.9. Nerva also leads on update cadence (weekly vs every 6 weeks) and ratings volume (15K vs 13). CanXida's advantage is in-app purchases (none vs 4) and review sentiment (83% vs 73%). On price, ads and device support there is nothing between them.

Both are free to download. Nerva sells 4 in-app purchases, starting at $43.99 per month. CanXida asks for nothing beyond the download.

Nerva holds the better App Store score, 4.7 against 3.9. That said, the two scores are not equally well evidenced: Nerva has 15K ratings behind it against 13, so its average is the more settled of the two. Written reviews complicate that: 73% of Nerva's written reviews are positive against 83% of CanXida's, so the app with the better star average is not the one people write more warmly about.

Nerva ships an update weekly, CanXida every 6 weeks. The most recent releases landed on September 24, 2026 and June 3, 2026 respectively.
