# 训狗教程 vs 空格网校

The clearest difference is in-app purchases: 空格网校 at none against 训狗教程's 1. 空格网校 also leads on ads (none vs shown). 训狗教程's advantage is iOS requirement (9.0 vs 12.0). On price and device support there is nothing between them.

Both are free to download. 训狗教程 sells 1 one-off in-app purchase. 空格网校 asks for nothing beyond the download.
