Heart Data Exporter

Apple Health has quietly collected your heart data for years — but getting it out, in a form you can actually use, is nearly impossible. Heart Data Exporter fixes that. It reads the cardiac data already on your iPhone and exports it in clean, open formats you own: spreadsheets, structured data, print-ready reports, and AI-ready datasets. Everything happens on your device.
Every heart-related metric Apple Health records, including:
• Heart Rate, Resting Heart Rate, Walking Heart Rate, Heart Rate Recovery
• Heart Rate Variability (HRV) and VO₂ Max (cardio fitness)
• ECG records with Apple's own rhythm classification
• Blood Oxygen, Blood Pressure, Respiratory Rate, Wrist Temperature

SIX EXPORT FORMATS
• CSV — a spreadsheet of every reading, for Numbers, Excel, or Google Sheets
• Excel (.xlsx) — a workbook with a summary sheet plus all readings
• JSON — structured data with full provenance, for developers and scripts
• Markdown — a clean, readable summary
• SQLite — a queryable database of your history
• PDF — polished, print-ready reports

AI-READY DATASETS
Hand years of your data to the assistant you choose. The AI export is a self-describing dataset — every metric labeled with its exact HealthKit identifier, units, and a plain-language definition — tuned for ChatGPT, Claude, and Gemini. Choose Summary (compact and token-efficient) or Complete (every sample with full provenance). The app produces excellent data; the questions are yours to ask.

REPORTS FOR A DOCTOR VISIT
Generate clean, print-ready PDFs on your iPhone:
• Doctor Visit — summary vitals, recent ECG history, and trends
• Annual Heart — your year in review
• Timeline — every cardiac metric on one shared axis

OBJECTIVE STATISTICS
Averages, medians, minimums, maximums, standard deviation, counts, and weekly and monthly aggregates — computed from your own readings and presented as plain facts.

FILTER EXACTLY WHAT YOU NEED
Export the last week, month, year, or a custom date range. Include a single metric or all of them — you decide the scope before every export.

PRIVATE BY DESIGN
• No account, no cloud, no analytics, no tracking
• Read-only access to Apple Health — it can never change your data
• Everything is processed on your iPhone; nothing is uploaded
• Files leave your device only when you choose to share them

FACTS, NOT CONCLUSIONS
Heart Data Exporter is a data-ownership tool, not a medical device. It reports objective statistics and passes through Apple's own ECG classifications, but it never diagnoses, never scores your health, and never tells you whether a value is good or bad. Any interpretation is between you and the professionals or tools you choose. It is not a substitute for professional medical advice, diagnosis, or treatment.

BUILT FOR

• Anyone monitoring blood pressure, HRV, or recovery
• Endurance athletes tracking fitness over time
• Preparing information for a physician visit
• Researchers and developers who want portable, well-structured data
• Anyone who simply wants a backup of their own heart data
