Health.md · In development
Your health history should live on your phone. Not on someone's server.
I'm building Health.md: an AI health companion for iPhone that keeps your medical history in context without ever sending it anywhere. Most health apps are free because your data is the product. This one isn't, because there's nothing to sell — the data never leaves your device.
Get early access
I'll email you when the TestFlight build is ready, plus the occasional note on what I'm building. That's it.
The AI runs on your phone
Health.md uses Apple's on-device Foundation Models, with Apple Private Cloud Compute as an optional step for long-form reports. Your questions aren't training anyone's model, and there's no account on a server somewhere holding your medical history.
Your records are just files
Everything is stored as plain markdown in the Files app. You can open it, read it, back it up, or delete the whole thing — without asking me for an export. No proprietary format, no lock-in, and nothing to lose access to if I ever stop building this.
Nothing is collected
No analytics, no telemetry, no third-party SDKs. The App Store privacy label reads “Data Not Collected,” and the vault is never synced to iCloud. That's a design constraint I've built the app around, not a policy I could quietly revise later.
Screen recording coming soon
Where it actually stands
Being straight with you, because I'd want the same: Health.md is not finished. The safety and retrieval core is built and tested — the part that decides when to stay quiet, flags anything urgent, and refuses to diagnose or give dosages. The conversational layer and the markdown vault are what I'm building next. Join the list and you'll see it come together, and you'll be among the first people in the build.
Requires iPhone 15 Pro or newer on iOS 27 — the on-device models need Apple Intelligence hardware. Health.md is not a medical device. It doesn't diagnose, prescribe, or replace your doctor; it helps you keep track of your own history and prepare for visits.
