Weight, fat percentage, water percentage and the weather (outside) are displayed on the scale. In the app, you can also check muscle and bone mass, heart and BMI. Nutrition is displayed, but I see it as a gimmick.
I didn't have a Withings before, so no direct comparison.
The fact that the scale synchronises via WLAN has advantages and disadvantages:
+ Fast synchronisation and no Bluetooth connection necessary.
- If two people in the family have approximately the same weight, the scale cannot distinguish between them.
