Oura Ring’s newest feature lets you spy on your friends

Oura, the company that produces the Oura Ring smart ring, has introduced its first social feature, which allows wearers to share certain data between friends. It’s called Circles, and its announcement is joined by the final release of its Sleep Staging algorithm, which has been in beta since 2022.

Oura’s CEO, Tom Hale, explained the thinking behind Circles’ launch:

“Our mission at Oura has always been to improve the lives of our members by taking a compassionate approach to health, and this new feature is just the next step in delivering a personalized experience that allows our members to connect with not only their bodies, but also their friends and family.”

Through Circles, you’ll be able to share the three main data points in the Oura Ring app — Readiness, Sleep, and Activity — collected over a two-week period. It’ll be down to you which scores you share and how often, and you’ll have the option of doing so daily or weekly. You can react to scores by using one of the custom emojis in the app and share data with up to 10 different Circles (which we assume to mean 10 different people). It doesn’t seem like you’ll be able to share any of the deeper data points, such as body temperature or resting heart rate.

Oura has also announced that its Sleep Staging algorithm will finally leave its beta stage and become the standard sleep-tracking system for the Oura Ring. It first launched in November 2022 and has been in beta ever since, with the option to switch between it and the old system available in the Oura app. Over the past months, it has been available to all Oura wearers, but the beta tag will now be removed for both Android and iOS users.

The algorithm is the result of two years of research and data collection from the Oura Ring and polysomnography (PSG) data from other sources, and Oura calls it “among the most accurate sleep-staging algorithms available in a consumer wearable.” It is in 79% agreement with PSG data for light, deep, REM, and waking sleep stages. The sleep-staging algorithm helps inform one of Oura’s other recent feature releases, your chronotype, to help you better understand when your ideal bedtime is.

Oura goes back to basics with its classy new Horizon smart ring design
The side of the Oura Ring Horizon.

This is the Oura Ring Horizon, a new version of Oura's excellent smart ring, this time with a subtle design and a brand-new color to go with it.

The Horizon joins the existing Heritage design, which is characterized by the slightly flattened section that breaks up the simple ring shape, but does give it a more masculine appeal. The Horizon is far more simple, adopting an entirely unfussy, and very traditional circular shape instead.

Is the Oura Ring finally good enough to replace your Apple Watch?
Oura Ring, iPhone 13 Pro, and Apple Watch Series 7.

I regularly wear the Oura Ring and the Apple Watch Series 7 together, as one fills in the gaps the other has in its arsenal of features. Through two recent updates, the Oura smart ring has increased its ability to monitor health and fitness with the addition of simple fitness tracking and SpO2 blood oxygen monitoring. Is the Oura Ring now a full-fledged health and fitness tracker ready to be worn on its own, without any compromises?
New features
Both the workout tracking and the SpO2 blood oxygen monitoring have been promised since the launch of the third-generation ring in 2021, so their arrival is overdue. The workout mode employs the ring’s heart rate tracking and came to the ring at the end of May, while the Sp02 feature came at the end of July. Once you set the feature up, it works automatically.

The workout mode is quite simple as it only looks at your heart rate to assess intensity, and doesn’t seem to use the accelerometer to cover movement, making it relatively basic when compared to other wearables. The SpO2 monitoring works when you’re asleep. With it, the Oura Ring also tracks Breathing Regularity — helping to identify changes in your breathing patterns overnight, which may be indications of sleep-related problems like sleep apnea.

Oura ring now syncs its temperature data with Natural Cycles app
The sensors in the Oura Ring.

Oura has announced a partnership with Natural Cycles, a birth control app, to enable automatic syncing of temperature data collected by its smart ring. Although it may sound like a basic feature, especially as cross-app syncing in health and fitness products is common, it streamlines the process of using the Natural Cycles app considerably.

Up until now anyone using the Natural Cycles app needed to manually enter temperature data each day, after obtaining it with a thermometer. It’s through this data the app helps people understand fertility cycles. Now, Oura will share data gathered by the temperature sensors in its smart ring overnight with the app, making it easier to use.
