The New App Makes Use of Heart Rate Sensors in the Smartwatch For the new app to work, it will use the heart rate sensors present inside your watch. The catch here is that the app doesn’t automatically read your blood pressure levels. For it to do that, you need to feed the data to the app manually so that it can calculate the blood pressure for you. You will take the readings from the medically certified cuff, which is known as calibration in Samsung. Then you will enter the reading into the app manually and using the algorithms present; the app will determine your blood pressure. Not the Latest Feature or Something New This app isn’t something very new or unseen for a Samsung Galaxy Smartwatch. The Galaxy Watch Active 1 is also capable of measuring blood pressure levels with the help of the My BP Lab. It is an app developed by Samsung in collaboration with the University of California, San Francisco (UCSF). This feature of the watch was only available in select countries though. Along with this, the app requested users to provide their consent for sharing data collected with the UCSF researchers.
