# 证件照制作助手 vs 量化组合模型

The clearest difference is iOS requirement: 证件照制作助手 at 15.0 against 量化组合模型's 17.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 证件照制作助手 sells 1 one-off in-app purchase and 量化组合模型 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
