# Secure Shield vs SmartClean AI

The clearest difference is rating: SmartClean AI at 4.4 against Secure Shield's 3.6. SmartClean AI also leads on ratings volume (3.3K vs 219) and chart position (#45 vs unranked). Secure Shield's advantage is review sentiment (68% vs 41%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Secure Shield sells 4 in-app purchases, starting at $9.99 per 7 days and SmartClean AI sells 10 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

SmartClean AI holds the better App Store score, 4.4 against 3.6. That said, the two scores are not equally well evidenced: SmartClean AI has 3.3K ratings behind it against 219, so its average is the more settled of the two. Written reviews complicate that: 68% of Secure Shield's written reviews are positive against 41% of SmartClean AI's, so the app with the better star average is not the one people write more warmly about.

Secure Shield ships an update every 3 weeks, SmartClean AI every 2 weeks. Both last shipped on November 9, 2026.
