Oura unveiled its new smart ring, the Oura Ring 4, on Thursday, which is available starting at $349. The company's rings track sleep, exercise, stress, heart health and other metrics to help users understand their bodies and make healthier choices. The Oura Ring 4 has new sensors, a sleeker design and up to eight days of battery life. Oura said it developed a new "Smart Sensing" platform that uses an algorithm and updated sensors to capture more accurate readings for blood oxygen sensing, daytime and nighttime heart rate and breathing disturbances.

The sensors in Oura's third-generation ring are raised and feel like little bumps, but the sensors in the Oura Ring 4 are flat. The company said this will give the ring a smooth interior that's more comfortable to wear. The Oura Ring 4 is available in twelve sizes and six colors, including a new black finish. It's available for preorder on Thursday and will begin shipping Oct. 15. In addition to the upfront cost, users will have to pay for a membership of $5.99 a month or $69.99 a year. The first month is free. Customers can use flexible spending accounts and health savings accounts to pay for the ring and the membership. A new look for the app
