# 解压专家 vs 证件照

The clearest difference is device support: 解压专家 at 3 against 证件照's —. On price, in-app purchases and iOS requirement there is nothing between them.

Both are free to download. 解压专家 sells 3 in-app purchases, starting at $1.99 per month and 证件照 sells 1 in-app purchase, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.
