## What is HealthSync?

HealthSync reads your sleep, activity, and workout data from the Health app and syncs it to your personal dashboard API.

HEALTH APP INTEGRATION
• Reads sleep analysis data including sleep stages (REM, Core, Deep)
• Sleep Tracker picker — choose your primary source (Oura, Apple Watch, iPhone, AutoSleep) to prevent duplicate data from multiple devices
• Configurable sleep debt threshold for personalised tracking
• Reads daily steps and active energy burned
• Reads resting heart rate and heart rate variability (HRV)
• Reads workout sessions with duration, calories, and distance

APPLE WATCH COMPANION
• Flow score dashboard with real-time gauge
• Health readiness indicator and today's activity pulse
• Cursor AI usage and budget tracking
• Server status monitor with 5 endpoint indicators (Flow, Health, Stats, Budget, Music)
• Watch face complication for at-a-glance flow score
• Offline caching — data persists when away from your network

FEATURES
• Connects directly to the Health app on your iPhone
• Syncs data to your self-hosted API endpoint
• Background sync keeps your dashboard up-to-date
• Apple Watch app syncs automatically from your iPhone
• Privacy-focused: your health data goes only to your own server
• No accounts required — configure your API URL and sync

REQUIREMENTS
• Requires a compatible dashboard API endpoint
• You must host your own server to receive health data
• Apple Watch requires paired iPhone with HealthSync installed
• See documentation for API setup instructions

Your health data is never sent to the app developer or any third parties. Data flows directly from the Health app to your configured server.
