Could be improved

I love that I can track my weight over time. Downside: It frequently puts my husband or my small daughter’s weight under my weight even though they are 100 lbs different. There’s no way to move it, you have to delete it.

I also wish it had the year on the date. It would be nice to track year by year.

I absolutely love this tracker!

You can’t beat the price, for sure, and it tracks everything better than the pricey apps. The scale is absolutely awesome. I bought it in December 2016 (it's now Oct 2019), use it about 3 times a week, and so far have only replaced the batteries one time.

Unlike the WAY more expensive Tanita that it replaced, it shows the same weight when you step off & step right back on. Three steps off the Tanita would give me three different weights. The Yunmai scale cannot be tricked like that.

Sometimes you have to turn the Bluetooth off and on once to get it to connect, but seriously, this scale is perfect. I love it.

How about Fat percentage goal?

This generally works pretty well and quick to record and transfer the data to my iPhone. The key is to wet my feet first ahead of time. Since weight alone doesn’t mean much depending on the muscle mass , height, age etc. I would love to able to set my goals based on other metrics particularly my fat percentage. It would be great if it has more analytical graph and data particularly the muscle mass in lbs instead of just percentage which could mean a gain or loss of muscle depending on the overall weight. But in general with the price for the smart scale and the easy of use of the app, I’m pretty happy with it.
