Do not use one of these apps and assume that the information provided is accurate or valid. Researchers are currently pioneering new technology that will allow physicians to take your blood pressure without a cuff. However, this technology is still in development. Make sure to visit the appropriate app store for your phone and operating system. At the app store, you’ll find a wide range of mobile health-monitoring applications that offer many functions.  Type in “blood pressure monitor” View the different results. Pick a few, select them, and read user reviews.

After you’ve read some reviews about a couple of apps, you need to select one and download it. In order to download the app:  Press the “download” button on your smartphone. This button may vary based on your operating system. Be patient while the program downloads. Download speeds may vary based on your internet connection speed.

The application will use photoelectric pulse wave signal stability information to calculate your blood pressure. This technology essentially analyzes your pulse, heart rate, and other information to arrive at health statistics. Hold your finger on the camera until the app tells you that its measurement is complete. Record the results.
