The watch is capable of measuring spO2 even if it’s not displaying the information and even if it’s no 100% accurate drops over a large enough time period combined with elevated heart rate would indicate a respiratory infection.
Whilst I agree that the data isn’t useful for most individuals releasing it to authorities around the world after anonymization would likely be quite valuable.
I might have had a mild infection don’t know if it was COVID-19 but it was A respiratory infection for sure.
Myself and my girlfriend were sick she had a fever I barely registered above normal we had coughs, sore throat I still can’t smell smoked salmon and she has stomach issues too.
It’s pretty much all gone now but one thing for sure we both had pretty high resting heart rate, as high as 110 during the worst of it.
My normal awake resting rate is around 65, it’s still around 80 despite all symptoms going away and trying to do some pushups today I realized that I’m extremely weak despite not feeling bad.
I usually do 5 sets of 20 pushups (controller, full range of motion) with a 50lbs resistance band today I felt myself gasping for air after 8-10.
