ŌURA is taking another step forward, going from being one of the best-in-class sleep trackers to introducing a personal heart health companion. The maker of the Oura Ring, the wearable device that analyzes sleep quality, sleep duration, stress levels, and many other metrics, launched two new features: Cardiovascular Age (CVA) and Cardio Capacity, both developed with the help of high-level experts.
The CVA feature will estimate ŌURA members’ cardiovascular age by recording their health activity for at least 14 days and providing a data analysis that will indicate if they are trending below, above, or in alignment for their chronological age. It will also identify behaviors that can negatively or positively impact their health span.

The Cardio Capacity feature will activate only by taking a walking test to establish a baseline VO2Max, a measure of the maximum amount of oxygen an individual can use during intense or effortful exercise in order to understand how well a person’s heart, lungs, blood vessels, muscles, and nervous system all work together. The better the user’s cardio capacity, the healthier their cardiovascular system will likely be across a lifetime.
These tests are usually inaccessible to the majority of the population, due to a combination of factors, such as affordability or availability.
“Prioritizing cardiovascular health is crucial for extending healthspan, as it supports physical vitality and resilience, and reduces the risk of chronic diseases,” said Dr. Shyamal Patel, senior vice president of science at ŌURA. “We know that health is not a moment in time or season; it’s a lifelong journey. And we want to help our members understand how their habits and behaviors today—like aerobic activity and sleep hygiene—impact their health as they age and how they can make changes that will pay off later in life,” said Holly Shelton, chief product officer at ŌURA.
ŌURA Ring was launched in 2013 and is accessible by subscribing to a membership through an app, at a cost of up to $399 per year. In less than ten years the brand has sold more than one million rings, raising more than $350 million in funding in three rounds. Celebrities like Kim Kardashian and family wear it every day, sharing their stats on social media and sponsoring the program.
