The Beurer BC57 is a practical wrist blood pressure monitor with Bluetooth connectivity that can easily be connected to your smartphone. All you have to do is wear the monitor on your wrist. Within seconds, the measurement will start and you'll see your systolic and diastolic blood pressure on the screen of the monitor. At the bottom of the blue, backlit display, you'll also find your heart rate. On the left-hand side of the display, there's a colored bar. This WHO indicator classifies your blood pressure based on values established by the World Health Organization. This monitor also lets you measure your average blood pressure over a certain period of time, which lets you learn more about your health. If the arrow ends up in one of the green bars, you don't have high blood pressure. You can review all data at a time that suits you in the HealthManager app, on the computer, or on your smartphone. The Beurer BC 57 switches off automatically when you're done using it.
