# F vs EQ

The clearest difference is price: EQ at Free against F's $2.99. EQ also leads on update cadence (every 2 weeks vs every 8 months) and review sentiment (90% vs 78%). F's advantage is in-app purchases (none vs 1) and rating (5.0 vs 4.8). On ratings volume, ads and device support there is nothing between them.

EQ is free to download; F costs $2.99 up front. EQ sells 1 one-off in-app purchase. F asks for nothing beyond the download.

F holds the better App Store score, 5.0 against 4.8. Both are backed by a comparable volume of ratings — 18 and 22 respectively. Written reviews complicate that: 78% of F's written reviews are positive against 90% of EQ's, so the app with the better star average is not the one people write more warmly about.

F ships an update every 8 months, EQ every 2 weeks. The most recent releases landed on October 9, 2026 and October 1, 2026 respectively.
