I am using Yunmai lightweight household body fat scale now. If you need to download the app, you can enter the information of multiple people. Every time you weigh, you can click on the corresponding person to test. With detailed data analysis, this body fat scale is very textured. However, I didn't buy it. It was a gift from an activity. It feels good and the market price is not low. You can search and see if it is suitable. I think it's good.
