The language of your blood pressure diary is english . The app supports other languages too ! The app does not support any Bluetooth devices! This is a diary to get statistics about your own blood pressure and heart rate. All data must be entered manually. The app is also not able to measure anything independently. New: - In the settings now a line for normal blood pressure, high blood pressure and hypertension 1 can be activated. These lines then appear in the graphic. With our blood pressure diary you will always have an overview about your heart rate / pulse, and store data such as systolic blood pressure, diastolic blood pressure, and heart rate as a note. Date and time of collection of blood pressure data are also saved. Just create a profile in your blood pressure app and then you can start saving your blood pressure data immediately as an overview. This is how you always find out if you have a hypertension. After 7 entries you can also call a statistic. You can also send the blood pressure data via e-mail to your doctor and even print it out. Our blood pressure app will be constantly improved. If you have any suggestions for improvement, please send us an email.
