There have been several new smart rings on the market. We are looking for a test winner in them. The smart ring is a device that directs its user towards a good sleep pattern, an active lifestyle and a healthy routine. Unlike a constantly charging smart watch or a plush sports bracelet, the smart ring is, at best, an unobtrusive part of everyday life. Until a couple of years ago, Finnish Oura was practically the only big name in the smart ring market. Now, more intelligent rings were made for the comparison.
