Body Comp offers a total body assessment with weight precise up to 50g, plus full body composition metrics  (body fat and water percentage, plus muscle and bone mass), cardiovascular assessment (Standing Heart Rate, Vascular Age), and an Electrodermal Activity Score, providing the most complete and accurate overview of body metrics ever offered. Every weigh-in appears in the Withings app automatically, via Wi-Fi or Bluetooth sync.
