Oura Ring 4
The Oura Ring is a solid health-tracking option for those who prefer mechanical timepieces. It gets a notable upgrade with the Oura Ring 4. A new Smart Sensing algorithm works with a redesigned battery of sensors to allow for a smooth inner surface and a thinner overall profile, while still keeping track of sleep, activity, stress, heart health, and more. Both the inner and outer surfaces are made from non-allergenic titanium, and despite the thinner profile, the battery can last for up to eight days on a single charge. Available for pre-order now, it arrives on October 14 in a range of twelve sizes with silver, black, brushed silver, matte black, gold, or rose gold finishes.
