# F vs Online Security App

The clearest difference is monetization model: Online Security App at free with in-app purchases against F's subscription. Online Security App also leads on review sentiment (94% vs 57%) and update cadence (every 11 days vs every 6 weeks). F's advantage is ratings volume (107K vs 52) and chart position (#172 vs unranked). On price, rating, 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 Online Security App sells 3 in-app purchases, starting at $7.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.6 for F against 4.5 for Online Security App. That said, the two scores are not equally well evidenced: F has 107K ratings behind it against 52, so its average is the more settled of the two. Written reviews are what separate them: 57% of F's written reviews are positive against 94% of Online Security App's.

F ships an update every 6 weeks, Online Security App every 11 days. The most recent releases landed on September 25, 2026 and July 4, 2026 respectively.
