# flow vs flex

The clearest difference is review sentiment: flow at 72% against flex's 28%. flow also leads on monetization model (free vs freemium). flex's advantage is update cadence (every 3 days vs fortnightly) and rating (3.4 vs 3.1). On price, ratings volume, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

flex holds the better App Store score, 3.4 against 3.1. Both are backed by a comparable volume of ratings — 7 and 18 respectively. Written reviews complicate that: 72% of flow's written reviews are positive against 28% of flex's, so the app with the better star average is not the one people write more warmly about.

flow ships an update fortnightly, flex every 3 days. The most recent releases landed on September 22, 2026 and September 21, 2026 respectively.
