# 协同签名 vs AI签字软件

The clearest difference is in-app purchases: 协同签名 at none against AI签字软件's 1. 协同签名 also leads on iOS requirement (13 vs 15.6). On price, ads and device support there is nothing between them.

Both are free to download. AI签字软件 sells 1 in-app purchase, starting at $0.99 per 7 days. 协同签名 asks for nothing beyond the download.
