The Withings WS-50 Smart Body Analyzer is not just a scale to check your weight and feel light as a cloud for the rest of the day. It gives you many more reasons to be justifiably proud about your health and fitness. The WS-50 checks your heart rate and the indoor air quality, and automatically uploads your readings to a smartphone app using Wi-Fi. This Health Mate app takes your readings and stacks them up against historical data to show you trends and improvements in your weight and body fat, resting heart rate and the air quality in your home. You can set a New Year resolution to lose a certain amount of weight, and the app will break it down into easier weekly targets. It even offers you tips on how to achieve your weekly target.
