Fitbit has many good things going for it, and it will only get better with the upcoming Versa 3 and Sense smartwatches. But it̵7;s hard to say nice things about Fitbit’s dials; they are just not good. That’s why the company’s new dial is exciting – it looks great and gives you SpO2 data directly on the screen.
Fitbit introduced SpO2 tracking at the beginning of the year. SpO2 (peripheral capillary oxygen saturation) is a method of tracking oxygen saturation in your blood. Some Fitbit watches use pulse oximeters to measure the relative reflection of red and infrared light from your blood via your wrist.
Deoxygenated blood (which travels along your veins back to the lungs) has a slightly darker red color than the completely oxygenated blood. With the help of that knowledge and the pulse oximeter, Fitbit can estimate your SpO2.
It’s good and good, but getting to the data was an annoying process. You had to dig into it in the health and sleep values of your app. Now that everything is changing with Fitbit’s latest dial. Instead of opening the app, activate the new dial and sleep as usual. Data will be displayed on your device within one hour after you wake up. Best of all, the watch’s face looks good – which is not a given with Fitbit.
Fitbit says you can install the new dial now, and more will come later.
