# Create virtual environment (recommended)
python -m venv venv
source venv/bin/activate  # On Windows: venv\Scripts\activate

# Install required packages
pip install -r requirements.txt

Create a .env file with your API credentials:

# WHOOP OAuth 2.0 (Browser-based authentication - no username/password needed!)
WHOOP_CLIENT_ID=your_whoop_client_id
WHOOP_CLIENT_SECRET=your_whoop_client_secret

# Withings OAuth credentials  
WITHINGS_CLIENT_ID=your_withings_client_id
WITHINGS_CLIENT_SECRET=your_withings_client_secret
WITHINGS_CALLBACK_URL=http://localhost:8766/callback

# OpenAI API for AI agent functionality
OPENAI_API_KEY=your_openai_api_key

📝 Note: WHOOP uses OAuth 2.0 browser authentication - you'll be redirected to login through their website when needed.

The system automatically creates the database and loads your health data:

# Complete setup: Creates database + Loads fresh data + Starts API server
python run_app.py

This will:

1. 📦 Create database tables (SQLite in ./db/whoop.db)
2. 🔐 Authenticate with WHOOP (browser popup for OAuth)
3. 🔐 Authenticate with Withings (browser popup for OAuth)
4. 📊 Load your health data (recovery, workouts, sleep, weight, etc.)
5. 🌐 Start the API server (http://localhost:8000)

🎯 Option A: Complete System (Recommended)

# Launches both API server (8000) + Chat interface (7860)
python start_health_chat.py

💬 Option B: Chat Interface Only

# Just the chat interface (requires API server running separately)
python chat_app.py

🤖 AI Chat Interface: http://localhost:7860

Example Questions to Try:

• "Show me my tennis workouts from 2025"
• "What's my weight trend over the last 30 days?"
• "How has my recovery been this month?"
• "Get my latest sleep data and analyze my patterns"
• "Show me my running performance with TRIMP scores"

🌐 REST API Access:

• Interactive API Docs: http://localhost:8000/docs
• Alternative Docs: http://localhost:8000/redoc
• Sample Endpoint: http://localhost:8000/recovery/latest

When you run python run_app.py, the system loads:

WHOOP Data:

• 📊 Recovery scores (HRV, RHR, sleep quality)
• 🏋️ Workout data (strain, heart rate zones, sports)
• 😴 Sleep tracking (stages, efficiency, duration)

Withings Data:

• ⚖️ Weight & body composition (BMI, fat ratio, muscle mass)
• 💗 Heart rate & blood pressure (systolic, diastolic)

The system automatically:

1. Creates SQLite database at ./db/whoop.db
2. Sets up all required tables
3. Handles data transformations and relationships
4. Manages duplicate prevention

• WHOOP: OAuth tokens auto-refresh, occasional re-authentication needed
• Withings: Long-lived tokens with automatic refresh (rarely need to re-login)
• Tokens stored securely in hidden files with proper permissions

• GET /recovery - Recovery scores and metrics
• GET /recovery/latest - Most recent recovery
• GET /workout - Workout data and strain
• GET /workout/latest - Most recent workout
• GET /sleep - Sleep performance data
• GET /sleep/latest - Most recent sleep

• GET /withings/weight - Weight and body composition
• GET /withings/weight/latest - Most recent weight
• GET /withings/weight/stats - Weight statistics
• GET /withings/heart-rate - Heart rate and blood pressure
• GET /withings/heart-rate/latest - Most recent heart rate
• GET /withings/summary - Withings data summary

• Activity is referenced in the context of a Physiological Cycle (Cycle for short).
• Current Cycle: Only has a Start Time. Past Cycles have both start and end times.
• A physiological day on WHOOP begins when you fall asleep one night and ends when you fall asleep the following night.

• Daily measure of body preparedness to perform.
• Recovery score: Percentage between 0 - 100% calculated in the morning.
• Calculated using previous day's data including RHR, HRV, respiratory rate, sleep quality, etc.
• GREEN (67-100%): Well recovered and primed to perform.
• YELLOW (34-66%): Maintaining and ready for moderate strain.
• RED (0-33%): Indicates the need for rest.

• Tracks sleep duration and stages: Light, REM, and Deep sleep.
• Calculates sleep need based on Sleep Debt and previous day's activity.

• Measurement of stress on the body, scored on a 0 to 21 scale.
• Based on Strain Borg Scale of Perceived Exertion.
• Strain scores tracked continuously throughout the day and during workouts.

• WHOOP tracks workouts and measures accumulated Strain over each workout.
