The Fitbit company just got ahead of Apple once again and has begun offering a new feature through a firmware update on its smartwatches, a feature that allows measure the level of oxygen in the blood, a feature that was available a few years ago in the Samsung S range but disappeared without a trace.
When Apple launched the Apple Watch on the market in March 2015 (it was officially unveiled in September 2014), the guys at iFixit discovered that the device appeared to have the ability to monitor blood oxygen levels, a function that seems not to be important enough for Apple as it has focused on adding other functions.
As we can read in the middle TizenHelp, some users of Fitibt devices in the United States have begun to have available through the application data related to blood oxygen monitoring. This is possible because they have a sensor capable of measuring oxygen in blood, a sensor that is only available in the Fibit Ionic, Versa and Charge 3 models.
In the new section of the Fitbit app where the information collected on blood oxygen levels is displayed, we can read:
The oxygen saturation in the blood normally fluctuates, but large variations can be related to respiratory problems. The estimated oxygen variation approximates the changes in your blood oxygen saturation.
If we take into account that the Apple Watch already has hardware capable of monitoring the amount of oxygen in the blood, it is likely that do not take much longer to be availableSince Fitbit models are not the only ones that also offer it, so this function will probably be activated with the launch of watchOS 7, a version that will almost certainly include a sleep quality meter.
