Withings Body Cardio Wi-Fi Digital Scale

Description

This is an awesome digital scale that syncs instantly with your smartphone, so you can track your progress over time. And not just weight—it also shows your BMI (body mass index), heart rate, muscle mass, bone mass, water percentage, your vascular age, and more. Charges with a microUSB cable—and once it's charged, it goes for a year without needing another charge. Great-looking design.
The second screen shows an actual GRAPH of your last few weigh-ins, complete with an indication of how much you've gained or lost since then—right on the scale! Super handy to see how you're doing.
The app (Withings Health Mate) is excellent—and, at your option, all of this data can also appear automatically in Apple Health, Google Fit, the Fitbit app, or any of 95 other fitness apps.
Can track up to 8 people in the same household; somehow, the scale knows who's who.
This scale is the current shipping model; it's 3 on Amazon as I write this. Get yourself a deal!

Body Cardio is the first smart scale to provide a cardiovascular check-up in less than 30 seconds from the comfort of your home. The scale delivers ultra-precise weight and composition measurements including body fat, water %, and muscle and bone mass, plus it syncs with the free Health Mate app to display your trends and help you reach your health goals. Unlike many smart scales, you don’t have to have your phone with you during weigh-in to synchronize your data over Wi-Fi. Body Cardio was developed with cardiologists and included in several validation studies with renowned hospitals in the EU and in the US.
