Your Apple Health data is sitting on millions of data points — what would you ask it?

We're launching Open Health soon — an open-source tool that turns your Apple Health export into clean markdown files you can feed into any LLM.

Your iPhone and Apple Watch have been quietly collecting data on your sleep stages, heart rate, HRV, workouts, nutrition, and more. But that data is trapped in a massive XML file nothing will open.

Open Health changes that. Export your data (six taps in the Health app), drop the zip in your browser or run the CLI, and get seven structured markdown files covering everything from weekly training summaries to sleep/recovery trends.

Then paste them into ChatGPT, Claude, or even a fully local model like Ollama — and actually have a real conversation about your health and fitness backed by your real data.

No account. No server. No upload. Everything runs in your browser. MIT licensed.

Curious — if you could ask an AI anything about your health data, what would it be?
