# 高校数学公式集 vs 数学図鑑

The clearest difference is update cadence: 高校数学公式集 at every 4 days against 数学図鑑's every 2 weeks. 高校数学公式集 also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). 数学図鑑's advantage is review sentiment (100% vs 92%). On price, ads and in-app purchases there is nothing between them.

Both are free to download. 高校数学公式集 sells 1 one-off in-app purchase and 数学図鑑 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

高校数学公式集 ships an update every 4 days, 数学図鑑 every 2 weeks. The most recent releases landed on November 3, 2026 and November 4, 2026 respectively.
