Health Monitor: Heart & BP

Record heart rate, blood pressure, blood sugar, and daily activity in one place — then review trends and suggestions over time.

❤️ Heart Rate Measurement
Place a fingertip over the rear camera to begin an automatic reading. The measurement uses the camera sensor and flash to detect pulse changes. Once the reading completes, review the result and confirm before saving. Previous readings are stored with timestamps, tags, and status labels for ongoing reference.

Note: Camera-based heart rate estimation builds on peer-reviewed photoplethysmography research (Liao et al., Nature 655, 2026) that validated pulse detection through smartphone camera sensors. Results provided by this app are for personal reference and wellness awareness only and should not replace a certified medical instrument.

🩸 Blood Pressure Logging
Enter systolic and diastolic values after each reading from an external monitor. A classification label is generated based on recognized blood pressure ranges. Saved entries appear in a timeline with individual reports and historical comparisons.

🍬 Blood Sugar Logging
Record blood sugar readings in either mg/dL or mmol/L. Entries are stored chronologically and can be reviewed alongside other health records in the tracker view.

📏 BMI Calculator
Enter height and weight to calculate body mass index. Results include a category label, and a history view tracks changes over time with a summary report.

🚶 Step Tracking
Read step counts from the system health service for the current day and the previous seven days. Estimated distance, calories, and active time are derived from the recorded step data.

💧 Water Intake
Set a daily water goal, choose a cup size, and log each serving throughout the day. A reminder feature helps maintain the recording habit. Daily totals and progress toward the goal are displayed on the home screen.

📊 Reports & Suggestions
View summary reports for each health category. Suggestions are generated from recorded values combined with age, gender, and activity status, using a template-based system. All suggestions are informational and do not constitute medical advice.

📰 Health Articles
Browse categorized health and wellness articles served from a remote content library. Each article includes related recommendations for further reading.
