ŌURA is the company behind Oura Ring — the smart ring that delivers personalized health data, insights, and daily guidance. With its advanced, research-grade sensors, Oura Ring packs state-of-the-art heart rate, heart rate variability (HRV), personalized temperature, activity, and sleep monitoring technology into a convenient, non-invasive ring — prioritizing both accuracy and comfort without compromise. Each day, these personalized health metrics are summarized into three scores: Readiness, Sleep, and Activity. While many wearables started with activity and fitness, ŌURA focused first on sleep because sleep is a daily habit and perhaps the most impactful daily practice on our overall health.
