Fitbit users in the US on Wednesday started seeing blood oxygen saturation data appear in the app, Tizenhelp first reported. Sensors on the back of the devices give users an estimate of the variability of oxygen levels in their bloodstream. This information is useful for detecting variations in breathing while you sleep, which could indicate sleep apnea.
Apple holds patents for blood oxygen monitoring, but has yet to activate the feature in any devices. Back in 2018, Garmin introduced Pulse Ox with its Vivosmart 4 activity tracker, allowing users to gauge their blood oxygen saturation levels on the spot, or periodically as they sleep.
French health tech company Withings recently unveiled its new ScanWatch, which also has similar monitoring capabilities. However, it is still undergoing FDA clearance, and the company has yet to announce when the watch will be available to purchase.
