# わたしの写真暗記帳 vs 生物の王様

The clearest difference is rating: 生物の王様 at 5.0 against わたしの写真暗記帳's 4.5. わたしの写真暗記帳's advantage is ratings volume (2.2K vs 1) and review sentiment (74% vs 59%). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 生物の王様 sells 3 in-app purchases, starting at $3.49 per month. わたしの写真暗記帳 asks for nothing beyond the download.

生物の王様 holds the better App Store score, 5.0 against 4.5. That said, the two scores are not equally well evidenced: わたしの写真暗記帳 has 2.2K ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 74% of わたしの写真暗記帳's written reviews are positive against 59% of 生物の王様's, so the app with the better star average is not the one people write more warmly about.
