Oura's $300 ring accused of guessing your sleep, not tracking it
Smart ring maker Oura is facing a proposed class action accusing it of deceiving customers about how well its $300+ rings actually track sleep. The suit, filed by Clarkson Law Firm, claims Oura can't detect real sleep stages (that needs scalp electrodes and eye sensors in a lab) and instead spits out AI guesses with, per the complaint, roughly a coin flip's odds of being right, despite marketing touting up to 95% clinical-grade accuracy. It matters because millions trust these numbers to shape real health decisions.
