Withings WS-50 Smart Body Analyzer Scale

The Smart Body Analyzer allows you to easily track your weight and monitor your progress. Not only does it let you know how much you weigh, it also calculates your BMI to give you a better idea of where you stand as far as weight-related risks are concerned. Additionally, it calculates your fat mass by bioelectric impedance to inform you about your body composition. Of course that's not all your Smart Body Analyzer does. It measures your heart rate, and detects the temperature and the CO2 level of the room.
