I wanted a new watch for exercise tracking, so I looked at Apple Watch 6. I was also excited about this SpO2 feature that the Apple Watch 6 has, even if I really don't need it. This feature is the main new feature that they are marketing their watch with. Just check out their web page and it is...
Does anyone know if the SPO2 monitor remains active during sleep? How often does it read the SPO2? I have sleep apnea so this is an intriguing feature for me, but only if it reads often enough to actually be useful information. Thanks in advance!
