Say hello to the Oura Ring 5. 40% smaller and lighter than the Ring 4, the all-new Ring 5 packs a health-tracking punch in its smaller form. A return to raised sensors offers better skin contact while more powerful LEDs and stronger signal pathways mean the Ring 5 can take clearer readings and boast improved accuracy. Add in improved battery life and the Oura Ring 5 is a step-up in the hardware stakes. Pair improved battery life with the new portable charging case, good for around four charges, and you could be looking at a month of power on the go.
But that’s not all this sleek health-tracking ring brings to the party. Oura Rings have always offered distraction-free health tracking things to their screenless design, but this came at the cost of viewing your performance during exercise. The Ring 5 introduces live activity tracking which will let you follow workouts and health metrics as they happen on your phone. You’ll also find the new Health Radar that will flag early signs of illness, overnight estimate blood pressure and more. It’s also expanded its focus on women’s health including the new Menopause Impact Scale.
