Finally, Fitbit has activated blood oxygen monitoring or SpO2 feature on its Versa family, Ionic, & charge 3 wearables. Today, many Fitbit users are reporting first-time blood oxygen saturation data with a graph inside the Fitbit app. Fitbit included a SpO2 sensor on the Versa series & Ionic to improve the health tracking powers. The recent fitness tracker, Charge 3, also comes with it, but the company postponed activating the function. It is impactful to track the stop breathing during sleep and monitor blood oxygen levels so most of the fitness-centric users were waiting for it.
Earlier this year, Fitbit CEO, Jack Park, promised to enable the function for all users in the coming fall. He said the SpO2 graph would be available for all the devices that have a SpO2 sensor. Now, almost a year after the launch of Charge 3, the company has opened the feature for all users. The function is helpful in the sleep score metric to measure sleep quantity and quality. Also, it is best in the detection of sleep apnea.

You will notice the Estimated Oxygen Variation option enabled in the Fitbit app when you receive the new update. As per the report we received while writing this article, the update is available in the USA. It is now rolling out on first-generation Fitbit Versa, Versa Lite, Versa 2, Ionic, and Fitbit Charge 3 devices. The SpO2 is already available on Mi Band 5, 5i, Huawei Band 4 Pr,o and some Huami Amazfit smartwatches.
