Good points

  • Good body fat accuracy.
  • Good weight accuracy.
  • Excellent weight sensitivity.
  • Easy to use.
  • Display OK to read.
  • Measurements can also be displayed on the app and stored for review.
  • Identifies previous set users (although if more than one user has a similar weight measurements can get confused).

But

  • No controls on scale (control is through an app on a smartphone or tablet).
  • Very cumbersome to set up for multiple users (each user has to sign up and accept an emailed invitation).

How we test

We took readings from 15 men and women. We then compared the results with those obtained from a DEXA (Dual-Energy X-ray Absorptiometre) scan, a machine used in hospitals for determining body fat composition.

Overall score includes:

Body fat accuracy (25%) - How accurately the scale measured body fat.
Weight accuracy (20%) - How accurately the scale measured body weight.
Weight sensitivity (10%) - How sensitive the scale was in detecting incremental changes of 100g.
Body fat deviation (15%) - Based on the reading that was furthest away from the DEXA scan. Measures how much it varied from the scan.
Ease of use (30%) - How easy the display was to read; how easy the controls were to programme and push with your toe; feet positioning; and how stable the scale was to stand on.
