# ZhiGe vs AI题库工厂

The clearest difference is device support: ZhiGe at 3 against AI题库工厂's 1. ZhiGe also leads on iOS requirement (15.1 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. ZhiGe sells 4 in-app purchases, starting at $0.99 per month and AI题库工厂 sells 2 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
