# F vs RFS

The clearest difference is price: F at Free against RFS's $0.99. F also leads on in-app purchases (none vs 13) and review sentiment (89% vs 74%). RFS's advantage is update cadence (every 3 weeks vs every 3 months) and ratings volume (24K vs 927). On rating, ads and device support there is nothing between them.

F is free to download; RFS costs $0.99 up front. RFS sells 8 in-app purchases, starting at $3.99 per month. F asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 4.6 for F against 4.6 for RFS. That said, the two scores are not equally well evidenced: RFS has 24K ratings behind it against 927, so its average is the more settled of the two. Written reviews are what separate them: 89% of F's written reviews are positive against 74% of RFS's.

F ships an update every 3 months, RFS every 3 weeks. The most recent releases landed on October 18, 2026 and October 19, 2026 respectively.
