9 Great Reads From CNET This Week: Smartwatches and SpO2, Paycheck Apps, Nightmares and More What we really get out of tracking blood oxygen levels with a smartwatch, how certain apps get you paid before payday, why we have nightmares, and other good stuff.


If you’ve got a smartwatch, chances are you’re using it to track some aspect of your health. During the pandemic, that might have included keeping tabs on your blood oxygen levels. Smartwatches from Apple, Samsung, Fitbit and Withings all offer that capability.
