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.
Yeah Fitbit is a toy, not a tool. The graphs are vague and the data behind them is inaccessible. The sensors are unreliable. The metrics are made up. The whole thing is a waste of time.
If they ever figure out a way to measure blood sugar or blood pressure, that would actually be useful. Until then I would much prefer a thinner and more comfortable watch without the protruding sensors.
DC Rainmaker did a quick review and the updated running activities looked comparable to Garmin, but no way to export or integrate them out. Of course Garmin is mature for 100+ activities.
