Once seen as a bit of a niche gimmick, smart rings have quickly become one of the most coveted wearables around. Discreet, stylish and packed with sensors, they can track everything from your sleep cycles to daily activity, all without strapping a chunky smartwatch or fitness tracker to your wrist.
The Oura ring has long dominated the space, spotted on celebrities and wellness enthusiasts alike, but it no longer has the market to itself. Samsung joined the fray with the Galaxy ring last year, Circular recently launched its second-generation device, and Ultrahuman has been rolling out more and more features. Even Apple is rumoured to be developing its own ring that could work with the Apple Vision Pro.
