# Face2Gene vs Red Book®

The clearest difference is rating: Red Book® at 4.8 against Face2Gene's 2.1. Red Book® also leads on chart position (#196 vs unranked) and device support (4 vs 2). Face2Gene's advantage is in-app purchases (none vs 2) and update cadence (every 3 months vs every 11 months). On price, ratings volume, ads and iOS requirement there is nothing between them.

Both are free to download. Red Book® sells 2 one-off in-app purchases. Face2Gene asks for nothing beyond the download.

Red Book® holds the better App Store score, 4.8 against 2.1. Both are backed by a comparable volume of ratings — 55 and 67 respectively. Written reviews complicate that: 17% of Face2Gene's written reviews are positive against 0% of Red Book®'s, so the app with the better star average is not the one people write more warmly about.

Face2Gene ships an update every 3 months, Red Book® every 11 months. The most recent releases landed on October 12, 2026 and October 13, 2026 respectively.
