GoKawiilOura adds Cardio Effort and automatic VO2 Max tracking to its smart rings
Oura is rolling out two new cardiovascular features for its smart ring: Cardio Effort, which rates weekly exercise strain from Light to Reaching based on a personalized baseline, and automatic VO2 Max, a beta feature that estimates aerobic capacity without requiring a manual six-minute walking test. VO2 Max activates automatically after a user completes five qualifying GPS-tracked walks, runs, or hikes, with results shown in the app's Heart Hub alongside trend data and personalized insights.
