Ōura Sleep Tracker and Smart Ring

The new Ōura ring comes with advanced sleep tracking features and daily guidance that helps users align their lifestyle, activities and sleep habits to their natural circadian rhythm – the 24-hour genetic clock that regulates the functions of the human body. Improving sleep and better aligning to your natural circadian rhythm can help users perform better at work, improve their athletic performance and live life at their full capacity.


Improving sleep is not a one-off feat. It’s a commitment. To make lasting changes and see results, the sleep monitor has to be durable, beautifully designed and comfortable to wear day and night.


The new Ōura ring builds on the success of the pioneering first-generation Ōura ring. It tracks sleep timing, sleep stages, night-time resting heart rate and heart rate variability, among other metrics. An improved temperature sensor is capable of tracking changes in nocturnal skin temperature with at least a 0.05 centigrade resolution.

Using the free Ōura app (iOS and Android), users can get an overview of their previous night’s sleep and sleep quality. The new ring will be accompanied by the updated Ōura app that enables users to follow up on long-term trends and see changes over weeks, months and years.


Ōura’s sleep analysis has been independently validated by the Stanford Research Institute. The new ring is set to bring even better accuracy and make it the go-to tool for longitudinal sleep research as well as the perfect validation tool for biohackers and discerning individuals.

The new Ōura ring is the future of sleep tracking and guidance. It’s the first truly personal and actionable device for improving sleep and aligning with your circadian rhythm.
