Integration with Wearable Devices (Apple Watch, Fitbit, etc.)

Summary Add support for integrating wearable health devices (e.g., Apple Watch, Fitbit, Garmin) to automatically sync vitals, activity levels, and sleep data into SymptomSync. This feature will enhance the app’s ability to provide a holistic view of the user’s health by combining self-reported logs with real-time sensor data.

---

Motivation / Why Currently, users manually log symptoms, mood, and vitals. Many already use wearables that continuously track heart rate, steps, sleep, and activity. By integrating these devices, we can:

• Reduce manual entry burden.
• Increase accuracy of health logs.
• Provide richer trend visualizations and AI insights.
• Enhance the app’s value for proactive health management.

Proposed Solution

• Device Integrations:

  • Use Apple HealthKit (for iOS) and Google Fit (for Android) as central APIs to pull wearable data.
  • Explore direct integrations with Fitbit/Garmin APIs for broader support.

• Data Types to Sync:

  • Heart rate (resting & active)
  • Steps & activity minutes
  • Sleep duration & quality
  • Weight & BMI (if available)

• UI Enhancements:

  • Display wearable metrics alongside existing health logs in the dashboard.
  • Overlay activity/sleep trends with symptom severity charts for correlation insights.

• Notifications / Insights:

  • Trigger in-app or push notifications when anomalies are detected (e.g., unusually high heart rate with logged chest pain).
  • Feed data into the AI chatbot for more personalized health recommendations.

Alternatives Considered

• Manual CSV import/export from wearable apps (less seamless, but could be an MVP).
• Limiting integration to only Apple HealthKit / Google Fit as a first step.

---

Additional Context This feature aligns with SymptomSync’s mission of smarter, real-time health tracking. It could also open opportunities for future predictive analytics (e.g., linking poor sleep with increased symptoms) and broaden adoption by health-conscious wearable users.

---

✅ Acceptance Criteria

• Ability to connect at least one wearable platform (HealthKit/Google Fit).
• Automatic sync of vitals & activity data into the Supabase database.
• Visualization of wearable data alongside existing health logs in the dashboard.
• Clear user consent & settings management for connected devices.
