# SQLDOU vs 一問から身につく SQL

The clearest difference is in-app purchases: 一問から身につく SQL at none against SQLDOU's 1. 一問から身につく SQL also leads on ads (none vs shown). SQLDOU's advantage is iOS requirement (16.0 vs 18.6). On price and device support there is nothing between them.

Both are free to download. SQLDOU sells 1 one-off in-app purchase. 一問から身につく SQL asks for nothing beyond the download.
