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.

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.

Does not sync past weights

App is buggy and does not have an easy way to transfer stored weights. It has a button to “manage storage” but when pressed it appears to simply delete all saved (non synched) weights without warning! Don’t buy if you want to be able to keep an accurate account of your weights over time.

Updated: After more investigating it has become clear that the app can only be used on one device. If it is on multiple devices the scale will upload the weights indiscriminately between the two devices and user profiles making the records incomplete on any device and a mixture of weights between people. This makes following trends over time totally useless.
