Your healthhas a signal.
Health Relay carries the Apple Health measurements you choose to the server and agent you choose. You decide what leaves your phone, who can read it, and when access ends.
The App Store listing is being prepared. Your launch link will appear here when Apple publishes it.

supported Health types
Steps, heart rate, sleep, workouts, and selected body and activity measurements. Health Relay says what it supports so you can make a clear choice.
- Scope
- Select the records that leave your phone. The app does not quietly copy the whole Health database.
- Access
- Give an agent only a separate read credential. Its types and expiration stay visible to you.
- Exit
- Pause uploads, export your cloud records, revoke an agent, erase data, or delete the account from the app.

The door opens when Apple says go.
The app is in release preparation. The App Store link will be replaced with the live listing as soon as it is published.
Planned pricing: $4.99/month or $49.99/year, billed through Apple.
Health Relay is a data-transfer tool, not medical advice or a medical device. It does not monitor emergencies. Apple Health permissions and background timing remain controlled by iOS.
