Trigger HRV-Measurement programmatically

Hey all,


I want to measure my Heartrate Variability (HRV) in specific time intervals continuously on my Apple Watch 4. Therefore I want to create a companion App (Apple Watch 4 App) to get the HRV-Values programmatically.


My Knowledge about the HRV Measurement is following:

it triggers only automatically

- if you reboot the apple watch 4

- if you put down the watch from you arm and wear it again

- if you use the breath-app for at least 1min


But I didn't find a way to trigger the HRV-Measurement manually / programmatically.

Is there a way or workaround to trigger the HRV-Measurement programmatically on the Apple Watch 4?


I need the HRV Values nearly in realtime to get the stress level on every time I want. If you can't trigger the HRV-Measurement, is there another way to get informations about the stress level nearly in real time of the person, that wears the apple watch 4?


Thank you in advance!

I am also looking forward to hear from Apple about this.
