# JLPT Pro vs AI题库工厂

The clearest difference is iOS requirement: JLPT Pro at 15.6 against AI题库工厂's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. JLPT Pro sells 3 in-app purchases, starting at $2.99 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.
