What's the best Android app for sharing blood pressure readings with my doctor during appointments?

Blood Pressure Tracker is specifically designed to facilitate communication between patients and healthcare providers. The app's export functionality creates detailed PDF reports that include systolic/diastolic readings, heart rate data, and visual trend charts spanning selected time periods. These reports can be emailed directly to physicians or printed for in-person appointments, eliminating the need for handwritten logs that often contain incomplete information. Users particularly appreciate the medication tracking integration, which shows how prescribed treatments correlate with blood pressure changes over time. The interface allows for quick data entry with customizable tags for different circumstances like morning readings, post-exercise measurements, or stress-related spikes. Some users note that the free version limits historical data exports to one-month intervals, though the paid upgrade removes this restriction. Reviews indicate healthcare providers respond positively to the organized presentation of data, which helps identify patterns more efficiently than scattered notes. The app also supports multiple measurement units and includes space for notes about symptoms or lifestyle factors that might affect readings.
