Oura Ring Makes Sharing Health Data a Social Thing With ‘Circles’

Here’s how to share Sleep, Readiness and Activity scores with friends and family who also have an Oura ring.

Have you ever wanted to know how well your friend slept last night? Not just by their own word of mouth, but with the receipt to prove it? Now you can with Circles, a new feature Oura announced Thursday for its app that lets you share different health data with up to 10 «circles» of people.

Circles will share Readiness, Sleep and Activity with people you allow in your circle — up to 20 per circle. You’ll be able to choose which kind of data you share with each group, so one circle can get more of your wellness information than another.

The three scores are summaries of the health data the ring collects, including temperature, heart rate and blood oxygen readings. Oura said it plans on expanding the type of information able to be shared in the future.

To start a circle, open the Oura app, scroll down the main menu and select «Circles.» Then you can name a circle, decide what scores you want to share and also decide whether you want that data to be daily or weekly averages. To invite people into the circle (they have to be fellow Oura users), you’ll send them a one-time link.

Once you’ve started your circle, you can view their scores and «react» with emojis, if you choose. Everyone has to sync their rings to keep the scores visible.

For people who enjoy collecting health data (and maybe boasting about a good health week), Oura’s Circles features is a good way to do that with other Oura wearers. According to a press release, though, the company is positioning Circles as another way to check in and connect with each other, which is becoming an increasingly important public health goal amid a loneliness epidemic, which has impacts on sleep, mental health and physical illness.

«Our mission at ŌURA 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,» Oura CEO Tom Hale said in a statement.

Oura’s Circles announcements comes as the company is advancing its sleep staging algorithm out of beta mode, which means everyone tracking sleep stages with Oura will get data from the new algorithm, which Shyamal Patel, the company’s head of science, calls «massive improvements of accuracy» in sleep data. The new algorithm has 79% agreement with polysomnography sleep tests done in a clinic, Patel told CNET.

Compared to Oura’s older sleep-tracking algorithm, ring wearers might experience slight changes in the amount of time Oura tells you you’re spending in deep sleep versus light sleep versus REM sleep.

«Those numbers are likely to shift a little bit,» Patel said.

YouTubers Sue Amazon, Claim AI Tool Was Trained on Scraped Videos

The lawsuit alleges that Amazon bypassed YouTube protections to collect content for its generative AI video system.

A group of YouTube creators is suing Amazon, accusing the tech giant of secretly scraping their videos to train its AI video model without permission.

The proposed class action lawsuit, filed in federal court in Seattle, alleges Amazon used automated tools to download and extract data from millions of YouTube videos to build and improve its Nova Reel generative AI system — a model that can create short videos from text prompts and images.

At the center of the complaint is how that data was obtained. The plaintiffs claim that Amazon bypassed YouTube’s protections using virtual machines and rotating IP addresses to avoid detection, effectively sidestepping the platform’s safeguards against bulk downloading.

The lawsuit was brought by several creators, including Ted Entertainment (the company behind the H3 Podcast and h3h3 Productions), as well as individual YouTubers and channel operators. They argue that the alleged scraping violated copyright law and the Digital Millennium Copyright Act, and are seeking damages as well as an injunction to stop the practice.

Amazon did not respond to a request for comment.

The case lands at a pivotal moment for generative AI, as courts weigh whether training on copyrighted material qualifies as fair use and how much control creators retain once their work is used to build these systems. The disputes have often centered on written material, which has been at the center of the AI revolution for several years, while AI video generators such as OpenAI’s Sora and Google’s Veo have emerged more recently.

The lawsuit is one of dozens testing the boundaries of AI training practices, alongside high-profile cases from authors, artists and news organizations, including lawsuits against OpenAI and Meta, all circling the same unresolved question: Where does fair use end and infringement begin?

The Galaxy Z TriFold Is Back. You Can Buy It From Samsung Soon

The $2,899 phone paused its sales in March after selling through its inventory, but Samsung is bringing it back to its online store.

Samsung’s $2,899 Galaxy Z TriFold is going back on sale on Friday, following a halt to its sales in March after the foldable phone sold through its inventory. Samsung has announced the TriFold’s return with a countdown clock on the phone’s online store page along with a Wednesday newsletter email sent to customers.

The initial pause, which Samsung said at the time was related to the TriFold being a «super-premium device in limited quantities,» happened after just three months of availability. The TriFold first went on sale in South Korea on Dec. 12 and then arrived in Samsung’s US store on Jan. 30. The TriFold sold out in the US within minutes of going on sale — which I know personally after joining my colleagues that morning in an attempt to buy it. Thankfully Senior Reporter Abrar Al-Heeti succeeded, and then reviewed the TriFold.

It’s unclear whether the Galaxy Z TriFold is now permanently returning to Samsung’s online store or if it is again on sale until its stock sells through. Given that the phone is very expensive, and unfolds to reveal a large, 10-inch display, it wouldn’t be surprising if its stock will be in limited quantities. We’ve asked a Samsung representative to clarify and will update if we hear more.

The Galaxy Z TriFold’s return also comes ahead of the summer season when we expect a slew of other foldable phones: Samsung typically refreshes its Galaxy Z Fold and Z Flip line in July or August, and Motorola has announced its first book-style Razr Fold phone will also debut during the season. And Apple’s rumored iPhone Fold (or perhaps iPhone Ultra based on latest rumors) could also be teased later this year.
