Companies like Apple, Google and Fitbit file scores of patents that never see a proper release. Of course, filing a patent doesn’t mean we’ll ever see the product on sale. However, Fitbit may be preparing these sensors for a medical play – and using transmissive detection could be the key to securing FDA approvals. Motiv was bought out and has pivoted to biometric security, and Amazon didn’t advance the Loop past its Day 1 Editions program.īut while Motiv and Oura impressed us in our reviews, a chunky smart ring is arguably more noticeable than a fitness tracker on the wrist.Īnd that’s perhaps why putting the features of a Fitbit into a smart ring isn’t technically difficult, there are warnings that users and consumers may not be as interested in the form factor. However, two of the big players – the Motiv Ring and Amazon Echo Loop – have been discontinued. The Oura Ring is the biggest player to date, which specializes in sleep and wellness tracking – and was involved in trials around its suitability for tracking COVID 19. The idea of a smart ring might sound far-fetched, but it’s an established form-factor that’s enjoyed niche success.
