# 一問から身につく SQL vs SQL入門クイズ

The clearest difference is in-app purchases: 一問から身につく SQL at none against SQL入門クイズ's 1. SQL入門クイズ's advantage is iOS requirement (12.0 vs 18.6). On price, ads and device support there is nothing between them.

Both are free to download. SQL入門クイズ sells 1 in-app purchase, starting at $1.99 per month. 一問から身につく SQL asks for nothing beyond the download.
