Fitbit has a lot of great things to offer, and it only gets better with the upcoming Versa 3 and Sense smartwatches. But it̵
Fitbit introduced SpO2 tracking earlier this year. SpO2 (peripheral capillary oxygen saturation) is a method of tracking the oxygen saturation in your blood. Some Fitbit watches use pulse oximeters to measure the relative reflection of red and infrared light from your blood off your wrist.
Deoxygenated blood (which travels back to your lungs along your veins) is a slightly darker red color than fully oxygenated blood. With this knowledge and the pulse oximeter, Fitbit can estimate your SpO2.
That’s all well and good, but getting the data was an annoying process. You had to deal with the health and sleep metrics in your app. Now that everything is changing with Fitbit’s newest watch face. Instead of opening the app, activate the new watch face and sleep as usual. The data will appear on your device within an hour of waking up. Best of all, the dial looks good – which isn’t something that Fitbit takes for granted.
According to Fitbit, you can now install the new watch face. More will follow later.
