Lode: Health Export for AI

Ask ChatGPT, Claude, or Gemini about your own health. Lode turns your Apple Health data — sleep, heart, workouts, 92 metrics — into one clean file any AI can read. Private, free, no account.



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 that drop the context AI needs to see 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.

• Knows Your Devices

Every metric says which device recorded it — Apple Watch, iPhone, a band, a ring, a scale. When two devices disagree, the file shows both so your AI can compare them.

• Your Sleep, Your Device

Wear one device to bed and another by day? Choose which one Lode uses for sleep. Each night comes from one device, and naps are listed separately.

• See What's Missing

Metrics with no data in your date range are flagged before you export, so nothing is silently left out.

• 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

Every feature, every metric. Tips appreciated, never required.



HOW IT WORKS

1. Choose health metrics and date range
2. Check size to ensure it fits your AI (Optional)
3. Share directly into ChatGPT, Claude, or Gemini - or save the file



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.



92 HEALTH METRICS. NO PAYWALL.

Every data type available to everyone. No premium tiers. No "upgrade to unlock."

Most popular exports:

• Activity: Steps, distance, flights climbed, active calories

• Heart: Resting heart rate, HRV, walking heart rate average

• Sleep: Time asleep, REM/Deep/Core stages, awakenings, efficiency, naps

• Workouts: Every workout type with duration, calories, heart rate data

• Body: Weight, body fat %, BMI, lean mass, wrist temperature

• Nutrition: Calories, macros, water, caffeine, vitamins, minerals

Plus: Respiratory, mobility, reproductive health, mental wellbeing, hearing, and more.



PRIVACY

Health data stays on your device. Period.

No servers. No accounts. No health data collection.



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, awakenings, and naps, night by night. JSON keeps structure. CSV loses it.

• Mixed frequencies

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

• Context

Which device recorded it, units, metadata. JSON keeps it. CSV drops it.

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



WHY FREE?

We built Lode for ourselves and now share it with the community. No VC funding. No growth hacks. No "free trial" traps.



NOT MEDICAL ADVICE

Lode does not provide medical advice. It's an export tool for generating a file you can choose to upload to an AI. Always double-check any AI-generated insights.
