Crazy DNA holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: Cross Virus has 8 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 29% of Crazy DNA's written reviews are positive against 100% of Cross Virus's, so the app with the better star average is not the one people write more warmly about.
Crazy DNA ships an update every 17 months, Cross Virus every 26 months. The most recent releases landed on October 3, 2026 and October 6, 2026 respectively.
