# 生物の王様 vs 高校数学公式集

The clearest difference is rating: 生物の王様 at 5.0 against 高校数学公式集's 4.5. 高校数学公式集's advantage is review sentiment (92% vs 59%) and update cadence (every 4 days vs monthly). On price, ratings volume, ads and in-app purchases 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 and 高校数学公式集 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

生物の王様 holds the better App Store score, 5.0 against 4.5. Both are backed by a comparable volume of ratings — 1 and 2 respectively. Written reviews complicate that: 59% of 生物の王様's written reviews are positive against 92% of 高校数学公式集's, so the app with the better star average is not the one people write more warmly about.

生物の王様 ships an update monthly, 高校数学公式集 every 4 days. The most recent releases landed on October 29, 2026 and October 27, 2026 respectively.
