Verdict
The clearest difference is rating: Trend Micro Mobile Security at 4.7 against Privacy Defender's 4.0. Trend Micro Mobile Security also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (29K vs 30). On price, review sentiment, update cadence and ads there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Trend Micro Mobile Security sells 8 in-app purchases, starting at $4.99 per month and Privacy Defender sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Trend Micro Mobile Security holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Trend Micro Mobile Security has 29K ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 68% of Trend Micro Mobile Security's written reviews are positive against 74% of Privacy Defender's, so the app with the better star average is not the one people write more warmly about.
Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 25, 2026 and August 25, 2026 respectively.
