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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 25, 2026 and August 25, 2026 respectively.
