Verdict

The call

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

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.
