Google’s Pixel Watch, a relatively recent contender in the smartwatch market, is making strides to catch up to its competitors by introducing new features. The latest update for the Pixel Watch includes the highly anticipated blood oxygen tracking functionality. Similar to its counterparts, such as the Samsung Galaxy Watch, Apple Watch, and Google-owned Fitbit trackers, the Pixel Watch will now monitor users’ blood oxygen saturation levels while they sleep and provide notifications of any notable changes.
