The scale
The scale that agrees with the mirror.
Step on each morning and Yorkstone records what you weigh and what that weight is made of. The reading joins your record on its own.
What it reads
Five measures, one step.
Weight is measured. The other four are estimates, and Yorkstone labels them that way wherever they appear.

How it estimates
Bioelectrical impedance, in plain words.
The scale passes a very small electrical signal between the pads under your feet. Water-rich tissue such as muscle carries it more easily than fat does. From how the signal travels, with your weight and the height, age and sex you give, the scale estimates body fat, muscle, water and bone.
A single reading moves with how much you’ve drunk, eaten or trained, which is why Yorkstone leads with your trend rather than any one morning.
We won’t quote an accuracy figure until we have published validation data.
Body composition readings aren’t for everyone. If you have a pacemaker or another implanted medical device, or are pregnant, don’t use them. [SAFETY GUIDANCE TO CONFIRM]
