Blood Pressure Check Diary: BP Info provides an interface for storing the readings of systolic, diastolic, and pulse pressure as well as the heart rate. All of these can be saved as an overview and viewed as a graph or a table.
A profile can be created for a patient so that the patient can start logging readings of blood pressure immediately and easily save their data as an overview.
The application is very smart in every term as the application indicates normal, high, and low blood pressure.
