# 猜您姓 vs 洞察Todo

The clearest difference is in-app purchases: 洞察Todo at none against 猜您姓's 1. 猜您姓's advantage is iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.

Both are free to download. 猜您姓 sells 1 one-off in-app purchase. 洞察Todo asks for nothing beyond the download.
