Wearables & Apple Health
Sync biometric data from Apple Health, Apple Watch, Garmin, and more.
Wearables & Apple Health
Connecting a wearable or Apple Health removes the manual work from your daily check-in. Sleep hours, step count, and heart rate metrics sync automatically — and the richer your biometric data, the more detailed your AI insights become.
Supported Sources
| Source | How It Connects | What It Syncs |
|---|---|---|
| Apple Health | In-app permissions (iOS only) | Heart rate, HRV, SpO2, sleep stages, steps, calories, body temp |
| Apple Watch | Via Apple Health | Same as above, with watch-specific accuracy |
| Garmin | Via Garmin API + device sync | Heart rate, HRV, steps, sleep stages, calories, stress score |
| Manual entry | Directly in the app | Any metric, any value |
Android users can connect Google Fit and Wear OS devices. Garmin devices sync across platforms via the Garmin Connect app.
What Data Syncs
| Metric | Unit | Notes |
|---|---|---|
| Heart rate | bpm | Resting and active values |
| HRV (heart rate variability) | ms (RMSSD) | Morning HRV is most useful |
| SpO2 | % oxygen saturation | Spot measurements and overnight averages |
| Sleep duration | Hours (decimal) | Total sleep time |
| Sleep stages | Hours | Deep, REM, and light sleep separately |
| Step count | Integer steps | Daily total |
| Calories burned | kcal | Active and total |
| Body temperature | °C or °F | Skin or wrist temperature |
| Respiratory rate | breaths/min | Overnight average from supported devices |
Connecting Apple Health
Open Settings in AVYCENNA
Go to Profile → Connected Sources → Apple Health.
Grant Permissions
iOS will show the standard HealthKit permissions sheet. Enable the metrics you want to share. You can always update these permissions later in the iPhone's Settings → Health → Data Access & Devices → AVYCENNA.
Sync Begins Immediately
Historical data from the past 30 days is imported on first connection. Going forward, data syncs automatically when you open the app or complete a check-in.
Connecting Garmin
Link Your Garmin Account
Go to Profile → Connected Sources → Garmin and tap Connect. You'll be redirected to Garmin Connect to authorize AVYCENNA.
Sync from Your Device
Sync your Garmin device with the Garmin Connect app as usual. AVYCENNA polls the Garmin API for new data automatically.
Data Point Storage
Each wearable data point is stored with full context:
| Field | Description |
|---|---|
| Metric type | e.g., heart_rate, hrv, spo2, steps |
| Value | The numeric measurement |
| Unit | e.g., bpm, ms, %, steps |
| Recorded at | Exact timestamp from the source device |
| Source | Which device or app provided the data |
| Source device ID | Device identifier for multi-device households |
This means if you have both an Apple Watch and a Garmin, their data coexists and can be compared.
How Wearable Data Enriches Insights
Wearable data flows directly into the AI insight engine. Having biometric data alongside your subjective check-in scores unlocks a new class of insight:
- Correlating your subjective energy score with your objective HRV
- Detecting sleep stage quality versus total sleep duration
- Identifying SpO2 dips that coincide with low-focus days
- Tracking resting heart rate trends alongside mood patterns
Even one wearable metric — just resting heart rate — meaningfully improves the quality of your AI insights. You don't need a premium device with every sensor.
Privacy
Wearable data is stored in your AVYCENNA account under the same privacy protections as your check-ins. Sharing wearable data with your doctor requires an explicit check_ins or dedicated wearables grant — it is never shared automatically.
