While these apps are a great idea, the unfortunate news is that they do not work. It is considered a "recreational" medical device and is not a legitimate medical instrument that records your blood pressure. 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. When reading reviews, focus on ease of use and people’s general happiness with the app. If users have rated the app with 3 stars or below, look for another. 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. To increase the speed, make sure to connect your phone to a wireless network. This will also help you save potential fees associated with data usage. Now that you’ve downloaded the app, you need to click on the icon that represents it. That will open the app. You’ll then want to use the app to measure your blood pressure.  If the app offers more diagnostics than blood pressure, select the blood pressure diagnostic option. Read the directions. Make sure your index finger is covering the camera on the back of the phone. 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.

Summary:
Understand that, this is not an accurate way to check your blood pressure. Visit the app store on your smartphone. Download an application. Use the application to read your blood pressure.
