Complete Metric Catalog
Every Apple Health metric AI Health Export can analyze
AI Health Export supports 155+ metrics across every category Apple Health tracks — 140 trackable source metrics listed below, plus 15+ auto-computed columns (sleep-stage breakdowns, ECG averages, daily calorie math, anomaly flags) that derive from them. This is not a curated subset — it covers virtually everything your Apple Watch, iPhone, connected devices, and health apps record.
Why 155+ matters
Competing AI health apps typically expose 30–90 metrics. AI Health Export covers the complete Apple HealthKit catalog because AI chat gets better the more context it has — a question like "why was my sleep off last Tuesday?" needs heart data, activity data, caffeine intake, and daylight exposure to answer well.
The Free tier includes a curated set of 20 foundational metrics — steps, heart rate, resting heart rate, heart rate variability, sleep (with stage breakdown), blood pressure, blood oxygen, weight, BMI, exercise time, and more — with 7 days of data. Premium ($14.99 one-time) unlocks all 155+ for CSV export. Pro ($14.99/mo or $149.99/yr) adds built-in AI Chat that analyzes them directly in the app.

Clinical Symptoms (with Severity)
10 symptoms × 2 columns = 20 CSV columns
Every symptom you log gets a daily count AND a max-severity score (Apple's HKCategoryValueSeverity: unspecified / notPresent / mild / moderate / severe). This lets AI correlate symptom spikes with HRV, sleep, and activity dips.

- Skipped Heartbeat
- Rapid Pounding or Fluttering Heartbeat
- Fatigue
- Dizziness
- Fainting
- Headache
- Wheezing

Note: Severity values verified against Apple's HKCategoryValues.h SDK header. AFib burden, sleep apnea, and fall count sit in their own categories above.

Frequently asked
Does the Free tier include all 155+ metrics?
Free includes a curated set of 20 foundational metrics — the essentials like steps, heart rate, sleep, HRV, blood pressure, and body weight — with 7 days of data. Premium or Pro unlocks all 155+ for CSV export, and Pro adds in-app AI Chat.
What CSV format does the export use?
One row per day with columns named in human-readable form (for example resting_heart_rate_bpm). Empty cells mean no data that day — never zero, never null. Designed specifically for feeding into ChatGPT, Claude, Gemini, or any LLM.
How does this compare to Health Auto Export?
Health Auto Export has ~167 metrics with a focus on detailed per-workout data. AI Health Export has 155+ with a focus on AI-optimized daily summaries and built-in chat. Most people use AI Health Export for the AI-chat value and the Free + $14.99 lifetime tiers, which Health Auto Export doesn't offer.
Are any iOS versions required for specific metrics?
The app requires iOS 18+. A few metrics are further gated: Sleep Apnea Event and Apple Sleeping Breathing Disturbances need iOS 18. Hypertension Event needs iOS 26.2+. Everything else works on any iOS 18+ device.
