Verdict
The clearest difference is price: 中医药草 at Free against PicToPDF's $0.99. 中医药草 also leads on update cadence (fortnightly vs every 4 months) and iOS requirement (13.0 vs 15.0). PicToPDF's advantage is in-app purchases (none vs 1) and ads (none vs shown). On device support there is nothing between them.
