It may look like a scale, but the Withings Body Scan goes way beyond weight, measuring body composition, heart rate, vascular health, and more. But unlike other smart scales that calculate muscle, fat, and water mass based only on readings from your feet, its retractable handle with electrode sensors allows measurements specific to the legs, arms, and torso. By tracking sweat-gland activity, for example, it can assess nerve activity associated with illnesses like diabetes. And by monitoring vascular age and heart rhythm, it can help improve cardiovascular health (an app offers personalized health plans). “We will turn the morning weigh-in into a sophisticated home health check,” Withings CEO Mathieu Letombe says. It is slated for a 2023 launch following FDA approval.
