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 — Unlock Your Apple Health - Chat with your Apple Health data using any LLM

Your iPhone collects millions of health data points but they're locked in a huge export.xml. Open Health turns that export into seven markdown files any LLM can read. Drop your zip in the browser, run the CLI, or beam it from your phone via WebRTC. Paste into ChatGPT, Claude, or a local model and ask real questions about your training and recovery. Everything runs locally — no upload, no server, no telemetry. MIT licensed, fully open source.
