The Oura Ring V2 improves on the original with improved accuracy, more power, better battery life and a more inconspicuous design. The innovative smart ring focuses on personal health and measures both sleep and physical activity. When measuring sleep, the Oura Ring V2 detects and analyzes the quality of rest, sleep stages and recovery by measuring heart rate, heart rate variability, pulse wave form, respiration rate, body temperature, movement and more. As an physical tracker, the ring counts daily steps, distance traveled and calories burned in a day.
The second generation of the Oura Ring was built with customer feedback in mind and many of the changes implemented were done to address issues with the previous models. The new ring is about half the size of the original and also comes in three distinct designs. Internally, the Oura Ring V2 comes with improved sensors, greater processing power, more memory and up to seven days of battery life.
