The Best Smart Rings to Rule Them All

There is plenty to consider when buying a smart ring, so use these tips to help you narrow your choice and get the best from it. Size: Some smart rings come in standard sizes, but there is some variation, and half sizes are rare. Finish: All the smart rings we tested combined tough titanium with a sensor array on the inside, but the coatings and colors vary. We tested the smart rings above with all the bells and whistles turned on, so our battery life estimates are lower than the manufacturers claim. Fitness tracking varies, with most smart rings offering basic step counts and movement, some offering manual workout tracking, and only the Oura and Galaxy Ring offering automatic workout recognition.
