# Learn Maths vs 知識庫

The clearest difference is update cadence: 知識庫 at every 6 weeks against Learn Maths's every 3 months. 知識庫 also leads on iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Learn Maths ships an update every 3 months, 知識庫 every 6 weeks. The most recent releases landed on October 12, 2026 and October 8, 2026 respectively.
