Lode: Health Export for AI

Export 92 Apple Health metrics as a clean JSON file built for AI analysis. Share directly into ChatGPT, Claude, Gemini, or any AI app. No messy CSVs or spreadsheets. Private, no account required.

THE PROBLEM

You've recorded months of health data. Apple Health's export gives you a 450+ MB XML file - too large for any AI to process. CSV apps give you flat spreadsheets, leaving out a lot of rich Apple Health data the AI needs to understand how things relate.

FEATURES

• One Enriched File More than raw data — computed insights, context, and an optional prompt to guide your AI.

• Share Instantly Send straight to ChatGPT, Claude, or Gemini apps - no download step. Or save the file and upload anywhere.

• Check Size Preview token count before exporting. Know if it fits your AI's context window.

• Siri & Shortcuts "Hey Siri, do a quick export." Instant export.

• Private By Design No account. No cloud. No servers. Health data never leaves your device unless you share your export file.

• 100% Free We initially built this for ourselves and are now sharing with the community. Tips appreciated, never required.

ENRICHED JSON FORMAT

Other apps dump raw numbers and hope AI figures it out. Our JSON export helps AI spot patterns humans can't see:

• Pre-Computed Insights Averages, trends, and baselines pre-calculated so AI can focus on finding deeper patterns.

• Correlation-Ready Sleep vs HRV. Exercise vs resting heart rate. Nutrition vs energy. JSON helps AI connect the dots across categories.

• Context AI Can Use Not just numbers - your data includes the "why" and "when" that turns stats into actionable insights.

• Embedded Prompt Optional context to help AI get started analyzing your data.

Raw data = AI guesses. Enriched JSON = AI discovers.

Health data stays on your device. Period.

WHY JSON BEATS CSV

Your health isn't a spreadsheet.

• Workouts Heart rate samples, splits, elevation as one connected object. CSV flattens into rows. JSON preserves relationships.

• Sleep REM, Deep, Core stages with quality scores. JSON keeps structure. CSV loses it.

• Mixed frequencies Daily steps, occasional weigh-ins, continuous heart rate. JSON handles naturally.

• Context Source device, units, metadata. JSON keeps it. CSV drops it.

CSV was built for Excel. Our JSON format was built for AI.
