what is an oura ring

The Oura Ring is a smart ring designed to track sleep and physical activity. It is a wearable device that uses advanced sensor technology to deliver personalized sleep and health insights straight from the most reliable source: your body. The ring is designed for accuracy above all because it measures from the palm side of your finger, where the pulse signal is strong to read from. The Oura Ring tracks and analyzes a host of metrics, including heart-rate variability (HRV), blood oxygen rate, body temperature, and sleep duration. It is stylish, lightweight, and comfortable, and comes in two styles (smooth or faceted) and multiple finishes (silver, black, matte black, gold, and rose gold) . The Oura Ring is waterproof and has a long battery life. It generates daily scores to provide a quick glimpse into the following health habits: activity, readiness, and sleep. The Oura Ring is not cheap, and it requires a monthly subscription.
