# 股票学习宝典 vs 数独世界

The clearest difference is ads: 股票学习宝典 at none against 数独世界's shown. 股票学习宝典 also leads on iOS requirement (12.0 vs 15.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.
