Oura wasn’t the first smart ring to market, but over the course of its life, the device has had surprisingly little competition. In general, it’s proven difficult for consumer hardware companies to find a toehold beyond the wrist. Though the brand’s relative success has no doubt raised hope that the fitness band/smartwatch isn’t necessarily the end-all-be-all for the category.

CES has never been a huge show for wearables, but the event that gave us our first glimpse at what seemed to be the first viable smart ring delivered two more this year. There’s Movano, which we highlighted late year. The company said it’s shooting for a second-half launch. Also notable is Circular. The French startup offered a sneak preview — but not much more — at the show.
