# CDC Yellow Book vs Anticoagulation Manager

The clearest difference is rating: CDC Yellow Book at 4.2 against Anticoagulation Manager's 2.3. CDC Yellow Book also leads on ratings volume (69 vs 4). Anticoagulation Manager's advantage is in-app purchases (none vs 2) and review sentiment (50% vs 20%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. CDC Yellow Book sells 1 one-off in-app purchase. Anticoagulation Manager asks for nothing beyond the download.

CDC Yellow Book holds the better App Store score, 4.2 against 2.3. That said, the two scores are not equally well evidenced: CDC Yellow Book has 69 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 20% of CDC Yellow Book's written reviews are positive against 50% of Anticoagulation Manager's, so the app with the better star average is not the one people write more warmly about.
