Health Data Integrations

Your wearable devices and health apps collect valuable objective data — sleep duration, heart rate variability, step count, and more. Health Check-In can pull this data in to give your subjective check-ins additional context.

Supported Integrations

• Oura Ring — direct connection for sleep scores, sleep stages (deep, REM, light), HRV, resting heart rate, and step counts
• Fitbit — direct connection for sleep scores, sleep stages, and step counts
• Apple Health (iOS) — sleep, steps, heart rate, HRV, respiratory rate, blood oxygen
• Google Health Connect (Android) — sleep, steps, heart rate, activity minutes

Data from additional wearables like Garmin and Apple Watch flows through Apple Health or Health Connect automatically.

How It Works

When you enable health data integration:

1. The app requests read-only access to specific health categories
2. At each check-in, relevant data from the past 24 hours is attached
3. This data appears alongside your check-in score in history and trends
4. AI Analysis can factor it into pattern detection

What We Read vs. Write

Health Check-In only reads data from your health platform. It never writes to or modifies your health records.

Privacy

Health data is read at the moment of check-in and stored locally on your device alongside the check-in. It follows the same privacy model as all other data in the app — on-device only, never sent to a server (except optionally during AI Analysis).

Why Objective + Subjective Together

Wearable data alone doesn't tell you how you feel. And how you feel alone doesn't explain why. By combining both, Health Check-In helps you connect the dots:

• "I felt terrible today — and my HRV was 30% below average"
• "Great day — I also got 8.5 hours of sleep last night"
• "My score has been climbing since I started hitting 8,000 steps consistently"

The combination of subjective experience and objective measurement is more powerful than either alone.
