An important aspect of any smartwatch is health and in that sense the Galaxy Watch4 does not disappoint with features such as measuring blood pressure, blood oxygen level, heart rate or electrocardiogram (ECG).
As a novelty, Samsung has included a 3-in-1 sensor «BioActive» which is used for PPG (Photoplethysmography), ECG (Electrocardiogram) and BIA (Bioelectrical Impedance Analysis).
Thanks to this chip, it is possible to perform a body composition analysis placing two fingers on the two side buttons, which act as electrodes, to measure the muscle mass, fat mass, body fat, body mass index (BMI) and body water.
Despite the small size of the buttons, Samsung claims the measurements are 98% reliable compared to much larger devices.
The new Galaxy Watch4 also allows you to track your workouts, with a database of over 100 different sports activities. To motivate you, Samsung has added more social interaction and group challenges to compete with your friends and family.
