Verdict
The clearest difference is monetization model: Cipher Challenge at free against Necrozone's paid. Cipher Challenge also leads on update cadence (every 3 weeks vs every 12 months). Necrozone's advantage is review sentiment (93% vs 67%) and ratings volume (60 vs 4). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
Cipher Challenge holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: Necrozone has 60 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 93% of Necrozone's written reviews are positive against 67% of Cipher Challenge's, so the app with the better star average is not the one people write more warmly about.
Necrozone ships an update every 12 months, Cipher Challenge every 3 weeks. The most recent releases landed on July 5, 2026 and June 2, 2026 respectively.
