It is also maddening to me the degree to which sensor information is hidden, or simply not available at all. I got my Pixel 2 watch specifically for fitness and sleep tracking. A year on, and I am still completely unable to perform a spot SpO2 check. I'll get a nice, pretty and utterly unlabeled graph of my supposed saturations when I sleep, but that's it. It definitely feels like the people that make it don't actually use the thing.
