what is a oura ring

The Oura Ring is a wearable smart ring that tracks sleep and physical activity. It was created by the Finnish health technology company Oura Health Oy in 2013. The ring is designed to be stylish, lightweight, and comfortable, and comes in two styles (smooth or faceted) and multiple finishes. The Oura Ring uses advanced sensor technology to track a variety of health metrics, including heart-rate variability (HRV), blood oxygen rate, body temperature, and sleep duration. It generates daily scores to provide a quick glimpse into the following health habits: activity, readiness, and sleep. The ring is waterproof up to 330 feet (ft), or 100 meters (m), and has a long battery life. The Oura Ring is available in several colors and styles, and can be worn on any finger on either hand. The device is paired with the Oura app, which provides personalized, highly accurate health insights through 3 daily scores: Sleep, Readiness, and Activity. The app adapts to the users body over time, providing tailored insights to help answer key questions about their health. The Oura Ring is a comprehensive health tracker that monitors a host of metrics both during the day and while the user sleeps, providing a holistic overview of their activities over a 24-hour span and determining how physically and mentally prepared they are for the day ahead.
