Apple Watch owners’ next must-have gadget is a sleep-tracking smart Oura Ring


In a world where you can get smart versions of almost everything, from speakers and watches to water bottles and running shoes, I find smart rings particularly fascinating. In some ways they are perfect to wear: unobtrusive, stylish and seamless to combine with the rest of your outfit. However, they’re far too small to pack a screen, so any data it collects is only available in the companion app.

Of all the smart ring offerings currently available, the Oura Ring is the best known and most used, topping our list of the best sleep trackers. The Oura Generation 3 is a solid wellness tracker focused on monitoring sleep and stress rather than pure fitness, with seven temperature sensors that monitor your “recovery time,” an updated heart rate sensor, and a readiness score, just like Garmin or Fitbit.
