# 魔法百科 vs 十万个为什么

The clearest difference is update cadence: 十万个为什么 at every 3 weeks against 魔法百科's every 3 months. 十万个为什么 also leads on iOS requirement (8.0 vs 12.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 魔法百科 sells 1 one-off in-app purchase and 十万个为什么 sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
