OPEN SOURCE

Build with your health data

VitaVault exports Apple Health data in three formats: CSV (for spreadsheets), JSON (for code), and AI-Ready (for pasting straight into ChatGPT, Claude, or Gemini). Everything is open source.

Three export formats

Each export gives you the same health data in a different shape — pick the one that fits your workflow.

1. AI-Ready (the easy one)

Plain text, pre-formatted for pasting into any AI chatbot. No code, no parsing — just copy, paste, ask.

HEALTH SUMMARY — Last 7 Days

Steps: 43,133 total (6,162/day avg)
Sleep: 6h 42m last night, 7.1h weekly avg
Heart Rate: 72 bpm avg, 62 bpm resting
HRV: 30ms avg (below optimal — possible stress or fatigue)
Blood Oxygen: 97% avg
Weight: 185.4 lbs
Active Calories: 4,645 total (616/day avg)
Exercise: 142 min total

Paste this into ChatGPT, Claude, or Gemini and ask:
"What should I focus on this week?"
"Prepare a summary for my doctor appointment"
"What do my HRV trends mean?"

2. JSON (for developers)

Structured data for apps, APIs, databases, or automation. Standard schema, easy to parse in any language.

{
  "exportDate": "2026-02-17T12:00:00Z",
  "deviceId": "anonymous",
  "period": "7d",
  "metrics": {
    "steps": { "total": 43133, "dailyAverage": 5719, "unit": "steps" },
    "sleep": { "lastNight": 6.7, "weeklyAverage": 7.1, "unit": "hours" },
    "heartRate": { "average": 72, "resting": 62, "unit": "bpm" },
    "weight": { "latest": 185.4, "unit": "lbs" },
    "activeCalories": { "dailyAverage": 542, "unit": "kcal" },
    "hrv": { "average": 30, "unit": "ms" },
    "bloodOxygen": { "average": 97, "unit": "%" }
  }
}

3. CSV (for spreadsheets)

Opens directly in Excel, Google Sheets, or Numbers. One row per day, one column per metric. Great for charts and tracking over time.
