# Sugaku vs 数学図鑑

The clearest difference is ads: Sugaku at none against 数学図鑑's shown. Sugaku also leads on device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, update cadence and in-app purchases there is nothing between them.

Both are free to download. Sugaku 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.

Both ship on a similar rhythm, roughly every 2 weeks. The most recent releases landed on August 24, 2026 and June 4, 2026 respectively.
