As one of the hottest smart rings on the market, the offers features and data collection that go a step beyond Oura for individuals looking to optimize their health. I tested one alongside the Oura Horizon ring for a month, wearing both around the clock and logging everything from my morning coffee to my late-night cocktails. Suffice it to say, the Ultrahuman ring will excite people dialed into their health and fitness.
The Series 10 release in September 2024 hailed the smartwatch's screen, 30% larger than previous models, and this is the 46mm model, so the screen size is indeed ample and very easy to read, day or night. The health and fitness features are terrific, including heart and respiratory rate tracking, irregular heart rhythm detection, sleep level and menstrual cycle tracking.
