# 用药提醒 vs Datata

The clearest difference is in-app purchases: 用药提醒 at none against Datata's 1. 用药提醒 also leads on iOS requirement (15.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. Datata sells 1 one-off in-app purchase. 用药提醒 asks for nothing beyond the download.
