# 点点水印相机 vs 产检助手

The clearest difference is in-app purchases: 点点水印相机 at none against 产检助手's 1. 点点水印相机 also leads on iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. 产检助手 sells 1 one-off in-app purchase. 点点水印相机 asks for nothing beyond the download.
