+# Research Plan: Health Data from Phone Frameworks
+
+## Objective
+Research what health data can be accessed from mobile health frameworks with proper permissions:
+- **Apple HealthKit** (iOS)
+- **Google Health Connect** (Android)
+- **Samsung Health SDK** (optional - additional coverage)
+
+## Research Areas
+
+### 1. Apple HealthKit (iOS)
+Research questions:
+- What health data types are available?
+- What permissions are required for each data type?
+- What are the user privacy requirements?
+- How to read historical vs real-time data?
+- What metadata is available (timestamps, device info, units)?
+- Any special requirements for medical data vs fitness data?
+
+### 2. Google Health Connect (Android)
+Research questions:
+- What health data types are supported?
+- What permissions model does Health Connect use?
+- How does it differ from the old Google Fit API?
+- What are the integration requirements?
+- Can it read data from third-party apps (Fitbit, Strava, etc.)?
+- What metadata is available?
+
+### 3. Data Type Comparison
+Compare both frameworks:
+- Which data types are available on both platforms?
+- Which are platform-specific?
+- Unit differences and conversions needed
+- Timestamp precision differences
+- Data granularity differences
+
+### 4. Technical Implementation Requirements
+Research:
+- SDK/library requirements for both platforms
+- Background data sync capabilities
+- Battery usage considerations
+- Data storage strategies (local cache vs direct sync)
+- Error handling for missing permissions
+
+## Expected Deliverables
+1. Complete list of available health data types for each platform
+2. Permission requirements mapping
+3. Comparison matrix (iOS vs Android)
+4. Recommended data model additions for MVP
+5. Integration complexity assessment
+6. Privacy and security considerations
+
+## Search Strategy
+Will research:
+- Official Apple HealthKit documentation
+- Official Google Health Connect documentation
+- Developer guides and best practices
+- Data type reference documentation
+- Permission and privacy requirements
+- Code examples and integration patterns
