Fitbit quietly permits blood oxygen monitoring on its wearables

Fitbit just beat the Apple Watch to adding this important health tracking feature

That ability should be showing up for U.S. users on Fitbit models with an SP02 sensor, which includes the Fitbit Ionic, Versa and Charge 3. Tizenhelp points out that it discovered the rollout because Fitbit users in the US started noticing new blood oxygen saturation data in the Fitbit app. This new feature is now rolling out to the Fitbit devices that have a SpO2 sensor.

Fitbit says the wearables use their existing infrared sensor to take the new measurement, and that healthy users should see only small variations in blood oxygen saturation during their sleep.

Have any of our readers received the update on their Fitbit? The Iconic include an SpO2 sensor, but Fitbit had yet to enable the feature, even as it shipped other wearables with that sensor.

Apple also has a patent for Apple Watch to track blood pressure and blood sugar monitoring is also said to be in testing as early as 2017.


"Fitbit is continuing to collect clinical data to test and develop FDA-cleared features for sleep apnoea", a Fitbit spokesperson told Gizmodo.

When the original Apple Watch was released in 2015, iFixit discovered that it appeared to have the ability to monitor oxygen levels in the blood. Apple accounted for 35% of the global wearable technology market as of the third quarter of 2019, followed by Xiaomi, Samsung, and Huawei, according to the International Data Corporation. We got fantastic health features and innovation from the most popular watched out there, but SpO2 is something Apple did not implement for its watches - even if it has offered VO2 max for some time now.

Of course, since the Apple Watch likely already has the necessary components for SP02 tracking, the company may be planning on enabling the feature on current and past Apple Watch models in a future watchOS update.
