# 心流时间 vs LED Chat

The clearest difference is in-app purchases: 心流时间 at none against LED Chat's 1. 心流时间 also leads on iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.

Both are free to download. LED Chat sells 1 one-off in-app purchase. 心流时间 asks for nothing beyond the download.
