Own your Apple Health heart data.
Apple Health collects years of your cardiac data, then makes it hard to get out. Heart Data Exporter sets it free — export heart rate, HRV, VO₂ Max, ECG, and more as CSV, Excel, JSON, PDF, SQLite, or an AI-ready dataset. Entirely on your iPhone.
$7.99 one-time · no subscription. Nothing leaves your device.
Your data. Out of the walled garden.
Apple Health is excellent at collecting heart data and frustrating at letting you use it anywhere else. Heart Data Exporter is the bridge: it reads what is already on your phone and hands it back to you in formats a spreadsheet, a database, a doctor, or an AI assistant can actually open — faithfully, with nothing added and nothing interpreted.
Six export formats
CSV, Excel, JSON, Markdown, a SQLite database, and print-ready PDF reports — pick the format that fits where your data is going.

Built to hand your data to any AI.
The AI export is a self-describing dataset: every metric carries its exact HealthKit identifier, units, definitions, statistics, and monthly aggregates — so an assistant has real context, not a wall of numbers. The app produces the data; the analysis is yours to ask for.

- ✓Exact HealthKit identifiers, units, and definitions included
- ✓Facts only — no diagnoses, scores, or advice baked in
Get your heart data out of Apple Health
If you have worn an Apple Watch for a few years, Apple Health is quietly holding tens of thousands of heart-rate readings, a running record of your HRV and VO₂ Max, every ECG you have taken, and more. It is your data — but Apple gives you no simple way to export it as a spreadsheet, hand it to a cardiologist, back it up, or feed it to an analysis tool. The built-in "export" buries everything in a single enormous XML file that nothing opens cleanly.
Heart Data Exporter exists for exactly that gap. It reads your cardiac data on-device and writes it out as clean CSV, Excel, JSON, Markdown, SQLite, or PDF, or as an AI-ready dataset you can paste into Claude, ChatGPT, or Gemini. You can scope it to the exact metrics you want — export just your ECG records, your HRV history, or everything — over any date range. And because the whole point is ownership and privacy, nothing is uploaded: the export is generated on your iPhone and stays there until you decide to share it.
Frequently asked questions
What is Heart Data Exporter?
Heart Data Exporter is an iPhone app that reads the heart-related data Apple Health has collected — heart rate, resting and walking heart rate, HRV, VO₂ Max, ECG records, blood oxygen, blood pressure, respiratory rate, and wrist temperature — and exports it in open formats: CSV, Excel, JSON, Markdown, SQLite, PDF reports, and an AI-ready dataset. Everything happens on your device.
Does my health data leave my phone?
No. All reading and exporting happen on your iPhone. The app has no account, no cloud, and no analytics, and it never uploads your data. A file only leaves your phone if you choose to share or save it yourself.
Does the app diagnose or interpret my heart data?
No — and that is deliberate. Heart Data Exporter is a data-ownership tool, not a medical device or a health coach. It reports objective facts and statistics (averages, minimums, maximums, counts, and mathematical trends) and passes through Apple’s own ECG classifications, but it never tells you whether a value is good or bad. Any interpretation is up to you and the professionals or tools you choose.
Which formats can I export?
CSV and Excel (.xlsx) for spreadsheets, JSON for developers, Markdown for a readable summary, a SQLite database for queries, print-ready PDF reports, and an AI-ready dataset tuned for Claude, ChatGPT, or Gemini.
How much does it cost?
Heart Data Exporter is a one-time purchase of $7.99. No subscription, no ads, and no accounts. The price is shown in your local currency on the App Store, and payment is handled by Apple.
What devices does it need?
An iPhone running iOS 18 or later, with heart data already in Apple Health (typically recorded by an Apple Watch). The data lives in Apple Health regardless of which app or device recorded it.
Your heart data belongs to you.
