# AI Engineer Quiz vs SQL入門クイズ

The clearest difference is iOS requirement: SQL入門クイズ at 12.0 against AI Engineer Quiz's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. AI Engineer Quiz sells 1 one-off in-app purchase and SQL入門クイズ sells 1 in-app purchase, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
