    This is where the Oura Ring shines. It tracks a wide range of health metrics — including detailed sleep stages, readiness scores, heart rate, stress, and activity — all collected automatically while you wear it. The sleep tracking is especially detailed and insightful, often more nuanced than what you get from regular smart watches.
