Three reasons it exists.
You own where it goes.
Apple Health keeps your data on your phone. We let you choose a second copy that lives on your terms — a server you run, an AI agent you talk to, a notebook in your vault.
- Local sync to any HTTP server on your network
- Encrypted cloud relay (max 15 min retention)
- Custom destinations via open agent skill
Encrypted before it leaves your phone.
Open Vitals uses modern crypto (X25519 + ChaCha20-Poly1305). The relay only sees opaque ciphertext. Even if our servers vanish, your past data already left as bytes nobody can read.
- X25519 key exchange · ChaCha20-Poly1305 cipher
- Pairing via QR code, out-of-band
- No account. No password. No tracking ID.

Made for AI agents.
The hard part of Apple Health for AI is plumbing. Open Vitals ships the receiving end as an open-source skill — your agent gets paired, polled, and decrypts payloads with one command.
- Works with Claude, OpenClaw, Cosmo, custom agents
- Open-source skill on GitHub (Exapta-Labs/openvitals-skill)
- Polls on demand or on schedule — your choice
In one minute
From install to first sync.
Install the app
Download Open Vitals from the App Store (TestFlight beta now, public soon). Grant access to the HealthKit categories you want to share.
Pair with a destination
Your AI agent runs the open-source skill, generates a QR code, and you scan it once. Encryption keys are exchanged out-of-band.
Data flows
Tap Sync or let it run hourly. Your agent decrypts payloads on its side. Local sync stays on your network; cloud relay holds ciphertext for 15 minutes max.
70+ metrics
Anything HealthKit exposes.
You toggle each category on or off during pairing. Nothing is sent until you say so.

Screens
It looks like a phone app should.
iOS-native, dark by default, every screen purposeful. (Screenshots from TestFlight build — final visuals dropping as the beta progresses.)
