The two mainstream smart rings go head-to-head. Oura pioneered the category and is on its fourth generation with years of sleep research behind it. Samsung entered with the Galaxy Ring, leveraging its ecosystem integration with Galaxy phones and Samsung Health. Both are titanium rings with multi-day battery, but the software experience and health algorithm maturity differ considerably.
