Complete Metric Catalog
Every Apple Health metric AI Health Export can analyze
AI Health Export supports 172 Apple Health metrics, exported as 220+ analysis-ready CSV columns — rows fan out into more detail (sleep into stages, blood pressure into systolic/diastolic, each clinical symptom into a count + severity pair, plus auto-computed daily math). Every metric listed below is one you can select and export. This is not a curated subset — it covers virtually everything your Apple Watch, iPhone, connected devices, and health apps record. Coming in v3.0: import all 8 Apple Health medical record types — medications, conditions, allergies, immunizations, lab results, procedures, vital signs, and clinical notes — from the health systems you link to Apple Health (your patient portals / MyChart). Insurance/coverage records are not read, exported, or sent to AI.
Why 172 metrics matter
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 172 metrics (220+ CSV columns) for export. Pro ($14.99/mo or $149.99/yr) adds built-in AI Chat that analyzes them directly in the app.

Frequently asked
Does the Free tier include all 172 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 172 metrics (220+ CSV columns) for 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 172 metrics (220+ CSV columns) 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.
