# Certo Mobile Security vs DeFNCE

The clearest difference is rating: Certo Mobile Security at 4.6 against DeFNCE's 1.0. Certo Mobile Security also leads on ads (none vs shown) and ratings volume (775 vs 1). DeFNCE's advantage is update cadence (every 4 weeks vs every 6 months) and review sentiment (100% vs 83%). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Certo Mobile Security holds the better App Store score, 4.6 against 1.0. That said, the two scores are not equally well evidenced: Certo Mobile Security has 775 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 83% of Certo Mobile Security's written reviews are positive against 100% of DeFNCE's, so the app with the better star average is not the one people write more warmly about.

Certo Mobile Security ships an update every 6 months, DeFNCE every 4 weeks. The most recent releases landed on September 25, 2026 and July 16, 2026 respectively.
