Introducing the Oura Ring 4, the latest advancement in wearable health technology crafted with an all-titanium design for durability and comfort. Powered by Smart Sensing technology, this smart ring continuously tracks more than 50 vital health metrics such as sleep quality, readiness, physical activity, heart rate variability, stress levels, metabolic health, and women's health indicators. Unlike wrist-worn devices, the Oura Ring measures biometrics directly from the finger arteries using infrared photoplethysmography (PPG), providing deeper and more precise insights. Its quiet operation and up to 8 days of battery life allow you to focus on your daily activities without distraction. The ring supports multi-ring functionality enabling easy style changes through the companion app. Accurate sizing is essential for optimal performance; sizes range from 4 to 15 with no half sizes available. The Oura Ring 4 integrates seamlessly with the updated Oura app that organizes data into Today, Key Values, and My Health sections for comprehensive wellness tracking. This smart ring is an ideal accessory for those seeking a discreet yet powerful tool to understand and improve their health.
