Health Data Server

The watch app requires watchOS 8+

This app was built to get heart rate, calories, and more from your watch into a stream overlay. It does this by sending the data to HDS Cloud (or an IP address/port you specify). A website hosted at can be used as a browser source in OBS to show the data.

This app can save workout data to Apple Health

- Show your heart rate on stream with just an Apple Watch. No extra heart rate monitors required.
- The app will only affect your Activity Rings if calories are enabled
- Heart rate color ranges. Know where your heart rate is at a glance.
- The overlay app comes with a plethora of customization options. Make your overlay look however you want.
- The overlay comes with a heart beat animation that matches your real heart rate
- The overlay can also play sounds to go along with the heart beat animation
- Even more data for advanced users:
- Motion
- Every single HKQuantityTypeIdentifier available in HealthKit (so pretty much anything)

Go to for information on how to set up the overlay.
