# REI BlackBook vs FlipperForce

The clearest difference is rating: FlipperForce at 4.3 against REI BlackBook's 3.7. FlipperForce also leads on update cadence (every 9 days vs monthly). REI BlackBook's advantage is review sentiment (100% vs 67%) and iOS requirement (13.4 vs 15.6). 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.

FlipperForce holds the better App Store score, 4.3 against 3.7. Both are backed by a comparable volume of ratings — 3 and 3 respectively. Written reviews complicate that: 100% of REI BlackBook's written reviews are positive against 67% of FlipperForce's, so the app with the better star average is not the one people write more warmly about.
