Thanks, Andrew. If I’m understanding this, data from HRV4Training will give me a collection of measurements, from which GC can derive a single reading for the day? Or if I do the morning reading, will GC import that as the “correct” reading for the day?
I’ve been using an Apple Watch app called AutoSleep, which also records a single HRV reading from a morning breathing exercise. I can access that data with a shortcut and then write it to a file. In theory, I could then import that file into GC, which would allow me to be using a consistent reading in both apps.
Just need to find the time to give it a try…
