The watch app requires watchOS 6.2+

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 hds.dev can be used as a browser source in OBS to show the data.

This app can save workout data to Apple Health

Features:

• 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)
