The Pixel Watch’s blood oxygen sensor has been finally put to use.
Apple, Samsung, Fitbit, and Garmin’s best smartwatches can measure your blood oxygen saturation (SpO2) levels. The Google Pixel Watch also has a blood oxygen sensor but the functionality was disabled at launch. That looks to be changing now.According to some posts on Reddit (via ), the SpO2 tracking feature has been enabled on some Pixel Watch units. Previously, the watch only let users measure the estimated oxygen variation (EOV), which is an indirect estimation of the changes in blood oxygen saturation levels. The Heart Metrics dashboard used to say that the SpO2 feature was not available for the watch.
