To monitor blood pressure on the Galaxy Watch Active 2, users will need to first calibrate the smartwatch and the app with a traditional cuff. They will then be able to tap to “Measure” the blood pressure anytime, anywhere through pulse wave analysis via the wrist sensors on the wearable. The Samsung Health Monitor app will then analyze the relationship between the calibration value and the blood pressure change to determine the blood pressure. Results can be synced to the app on your phone, letting you track readings and fluctuations over a longer period of time.
