I was very excited to pick up this scale. The convenience of the wifi networking to auto update my data to their server and subsequently view on the iphone app sounded really really good.
In theory, the scale did as expected, however, the software component leaves a lot to be desired. For starters and this is the show stopper, the Body Fat % is completely wrong, not just a little wrong as you would expect with an estimated value, it's off by a lot. I had been using a considerably cheaper digital scale that gave me body fat readings and the Withings scale was nearly 30% off (in my case, 29% versus 24%).
I naturally assumed the Withings scale was the one that was correct (or hoped this was the case since it gave a much lower body fat %). I was annoyed enough by the difference that I decided to go and do a hydrostatic body fat test (the dunk tank), which is considered the gold standard in body fat estimation.
The results were surprising,...
