1byone Wellness 2.0 4+

I have had this scale and app a couple of years now. I love that it connects to Apple health and shows all of the past data/history. However, it is not user friendly and the interface is outdated and a poor design. Also, I don’t find that it’s very accurate for some measurements....sure weight is accurate, but after using a professional body fat % scale I found that this scale/app is adding 3-5% body fat more than what I actually have.

I also don’t like that you can’t manually add measurements or alter them. It would be nice to input the body fat % from the professional scale and have that visible in my history on the app and to see if that will change the way the scale reads future body fat % measurements. Additionally, I don’t understand how it is calculating the bone mass and how my bone mass could “decline” that significantly in a 3 year period.

Lastly, the fitness/activity section should offer more options in terms of activity levels or sync with the Apple Watch so that the app could have more accurate data regarding physical activity.

This app works well to connect with the company’s smart scales to download data, but it is lacking in many ways.

The history display is annoying. Instead of letting you set a time scale and then flip between measurements (body weight, muscle weight, ...), it resets the time scale every time you change measurement, and it doesn’t remember your preferred display window between sessions. Also won’t let you set the units (e.g. body fat percentage vs body fat weight in lbs or kg, etc.).

The annotation on the BMI scales is not consistent with the current medical literature. BMI in the 24 to 28 range is colored red indicating danger, but in fact there is no evidence for excess mortality in this range.

It connects easily and without problems with my IOS device. The readings though: the BMI is useless (takes height vs weight), the fat %, not even close. If you use it as an idea to keep track, it will work (going down from 25% to 22% will probably mean you lost 3% of bodyfat) not paying attention to the actual percentage that is. For instance, I have a fat caliper and after taking 5 measurements, the average says I am at 12%, however the scale while using the 1byone health app says 22%, and the same scale using the wellness app says 18%.
Make sure you take your readings at the sane time, after doing the sane things over and over. For example, if you take them before going to sleep at night, be consistent. Remember the scale is sensitive to the amount of water in your body, so being hydrated or not will make a difference.
