As of 2015 Blood Pressure Companion is a free app made by Maxwell Software that allows users to track their blood pressure, heart rate and weight. The app is available for the iPhone, iPad and iPod Touch devices, as the Blood Pressure Companion page on iTunes explains.
Blood Pressure Companion lets the user keep track of his previous 10 blood pressure readings, recording systolic and diastolic readings, heart rate, weight, and mean arterial pressure. The app displays comprehensive weekly reports. Users are able to email these reports to their physicians or print off hard copies, and they are also able to set reminders to take their blood pressure, as Maxwell Software explains.
