# F vs Avira Mobile Security

The clearest difference is monetization model: Avira Mobile Security at free with in-app purchases against F's subscription. Avira Mobile Security also leads on review sentiment (67% vs 57%). F's advantage is rating (4.6 vs 4.3) and ratings volume (107K vs 4.6K). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. F sells 10 in-app purchases, starting at $2.99 per month and Avira Mobile Security sells 10 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 4.3. That said, the two scores are not equally well evidenced: F has 107K ratings behind it against 4.6K, so its average is the more settled of the two. Written reviews complicate that: 57% of F's written reviews are positive against 67% of Avira Mobile Security'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, Avira Mobile Security monthly. The most recent releases landed on September 24, 2026 and September 23, 2026 respectively.
