# E資格 問題集 vs AI

The clearest difference is iOS requirement: E資格 問題集 at 15.1 against AI's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. E資格 問題集 sells 1 one-off in-app purchase and AI sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
