Verdict
The clearest difference is rating: F at 4.6 against Privacy Defender's 4.0. F also leads on ratings volume (107K vs 30) and chart position (#161 vs unranked). Privacy Defender's advantage is review sentiment (74% vs 57%). On price, update cadence, ads and in-app purchases 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. F sells 10 in-app purchases, starting at $2.99 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.
F holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: F has 107K ratings behind it against 30, so its average is the more settled of the two. Written reviews complicate that: 57% of F'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.
F ships an update every 6 weeks, Privacy Defender every 3 weeks. The most recent releases landed on September 25, 2026 and August 25, 2026 respectively.
