# AI vs Security Master

The clearest difference is rating: Security Master at 4.4 against AI's 3.7. Security Master also leads on ratings volume (4K vs 25). AI's advantage is ads (none vs shown) and review sentiment (75% vs 55%). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. AI sells 3 in-app purchases, starting at $19.99 per 7 days and Security Master sells 2 in-app purchases, starting at $8.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Security Master holds the better App Store score, 4.4 against 3.7. That said, the two scores are not equally well evidenced: Security Master has 4K ratings behind it against 25, so its average is the more settled of the two. Written reviews complicate that: 75% of AI's written reviews are positive against 55% of Security Master's, so the app with the better star average is not the one people write more warmly about.

AI ships an update every 5 days, Security Master every 11 days. The most recent releases landed on October 7, 2026 and October 20, 2026 respectively.
