For the past few weeks, the Pixel Watch has been missing estimated oxygen variation (EOV) data in the Fitbit app, but the graph is now back. This metric is an “approximation of the changes in your ...

Smartwatches can measure everything from heart rate to sleep quality, but one health metric has become particularly relevant over the past two years: blood oxygen saturation. Two of the world's ...
