What Data Vitalstat Syncs from Apple Health

Through iOS HealthKit, Vitalstat reads specific metrics recorded by your Apple Watch, iPhone, or other smart devices connected to your Apple Health database:

  • Workouts — All workout types with duration, heart rate, and active energy burned
  • Heart Rate Variability (HRV) — Used directly for computing your daily recovery score
  • Sleep analysis — In-depth sleep stages (Deep, REM, Light, Awake) and total duration
  • Resting Metrics — Resting Heart Rate (RHR) and sleeping respiratory rate
  • Vital metrics — Blood oxygen saturation (SpO2) and body temperature deviations
  • Body Composition — Weight, height, body fat percentage, and lean body mass
  • Daily Activity — Step count, active calories, and stand hours

How to Connect Apple Health

  1. Download Vitalstat from the App Store
  2. Open the app on your iPhone and begin setup
  3. When prompted, select "Connect Apple Health"
  4. A native iOS permission screen will appear; toggle the data types you wish to share
  5. Tap "Allow" in the top-right corner to establish the sync connection

Native Background Sync

Unlike other health platforms that require opening the app to trigger a sync, Vitalstat uses native iOS background refresh. Whenever Apple Health records a new metric (e.g., when you log a workout or wake up from sleep), iOS alerts Vitalstat in the background to import the fresh data. Your dashboard, home screen widgets, and watch complications stay continuously updated.

Privacy-First Architecture

At Vitalstat, we treat your health data with absolute confidentiality. All information read from Apple Health is processed and stored locally on your device. We do not upload your raw health metrics to external cloud servers, nor do we integrate third-party analytics or ad SDKs. Your health data remains yours alone.

Frequently Asked Questions

How does Vitalstat connect to Apple Health?

Vitalstat uses Apple's secure native HealthKit API. When you set up the app on your iPhone, iOS prompts you to select which health data types you want to share. Once permissions are granted, Vitalstat syncs your data automatically in the background.

Can Vitalstat write data back to Apple Health?

Currently, Vitalstat reads data from Apple Health to calculate your daily recovery score, sleep metrics, and provide AI insights. Vitalstat does not write or modify your Apple Health records, maintaining strict read-only access for maximum data integrity.

Does syncing Apple Health drain my battery?

No. Vitalstat uses Apple's built-in background delivery system. It only receives notifications when iOS updates health records, allowing the system to sync data with negligible battery and CPU impact.

Can I combine Apple Health with Garmin or Oura Ring?

Yes! Vitalstat allows you to connect multiple devices. You can connect Garmin, Polar, or Oura Ring directly via their cloud APIs, and also connect Apple Watch via HealthKit. Vitalstat consolidates all sources into a single unified recovery score.
