More than a dozen of smartwatches and fitness bands are available in the market, but Fitbit is one of the known brands in the wearables market. Although it lags in terms of market share as compared to the leader, Apple Watch, the latest update puts it ahead in at least one segment. Fitbit watches and bands have received SpO2 support that lets you track blood oxygen levels. The update is not there in any of the Apple Watch devices yet.
Based on the report, the Fitbit wearables in the US have started receiving SpO2 support. It is available in Fitbit Ionic, Versa, Versa Lite, Versa 2 and Charge 3 fitness trackers as of now.
“Blood oxygen saturation normally fluctuates, but big variations can be linked to breathing issues. Estimated oxygen variation approximates the changes in your blood oxygen saturation,” states the app. It is confirmed in the Fitbit app. Since the feature has already started rolling out in the US, it might soon be reaching other countries as well.
So if you are waiting for the next Apple Watch version to get SpO2? Probably not. It is worth adding that Fitbit Ionic is over two years old in the market so it probably had the hardware but the feature was not enabled yet. Similarly, Apple Watch might also be sporting the hardware but the feature is not enabled yet.
If you are the US-based and own a Fitbit device, you can track the blood oxygen saturation level while you sleep or work out right from the app. You just have to update the app to the latest version to see the graph change.
Apart from the Fitbit, the Honor Band 5, Huawei Band 4 Pro, Xiaomi Mi Band 4 and a few others already have SpO2 support.
