But the people who scrunch up their noses? They usually say something along the lines of, “Hm. Maybe when it’s lighter or smaller.”Good news. The newly announced $399 Oura Ring 5 is both. It’s 40 percent smaller than the Oura Ring 4, measuring 6.09mm wide (down from 7.9mm) and 2.29mm thick (down from 2.88mm). Depending on the size, it weighs from 2 to 2.69g. You’d think it might be hard to notice much a difference between the Oura Ring 4 and 5 — two very small wearables. But slipping the Oura Ring 5 off a ring stand and into my palm? It’s immediately noticeable. On my finger, it’s slimmer, too.The design doesn’t look that different, though Oura told me in a press briefing that it was reengineered to include stronger LEDs and optimized battery life that can last for six to nine days. (Alas, petite-fingered friends: Larger rings always have longer battery life.) The ring itself is titanium and IP68 weather resistant, and the coating is reportedly less scratch-prone than previous models. (Though I will be the judge of that in testing. I will never forget how deeply I was burned by the rose gold Oura Ring Gen 3.) The optional charging case now also holds five full charges and works with wireless chargers. There’s also a new “deep rose” color, which is more of a coppery rose gold than pink.The Oura Ring 4 in ceramic on my middle finger. The Oura Ring 5 is on my index finger.There are a few disappointments. As with the Oura Ring 4, the company is recommending that people seeking to upgrade double-check their size with a new sizing kit. Because of the redesigned components, people can get stuck with an “in-between” ring size, which may require going larger or smaller to be more comfortable. Also, while the Oura Ring 4 was available in sizes 4 to 15, the Oura Ring 5 will only come in sizes 6 to 13. At my briefing, I was told that’s because the Oura Ring 4 isn’t that old yet (it launched at the end of 2024) and the company is still figuring out how much demand there is for the newer sizes. Another bummer: There’s no ceramic option yet.Alongside the hardware, Oura is also announcing a ton of new software updates today. Building on Symptom Radar, which detects early health changes, the company is launching something called Health Radar. This suite of features includes nighttime blood pressure and nighttime breathing trends, the ability to import medical records, and a partnership with Council AI for a medical chatbot. (The latter two features require you to participate in the experimental Oura Labs beta testing feature.) The idea is that Health Radar will flag when a significant change happens in your health without having you look at each metric separately every day.RelatedOura Ring 4 review: still on top — for nowFor folks interested in metabolic health, Oura is also adding GLP-1 insights and lab uploads. At my briefing, I was told the GLP-1 insights are meant to help users keep track of their dosages, monitor changes and side effects, and get a sense of what’s normal regarding how the medication may affect their metrics. For example, GLP-1s can cause a mild increase in resting heart rate. Lab uploads will allow Oura users to directly import test results into the app and chat with Oura’s AI chatbot about the findings. (As always, an obligatory reminder that most AI health features are capable of hallucinations and poor advice, so it’s a bad idea to think this can replace your doctor.)The $99 charging case (sold separately) is getting a minor upgrade. The new one (left) now supports wireless chargers.Fitness-wise, live activity tracking is also improving in the Oura app. You’ll now be able to pair a third-party heart rate monitor to the Oura app, as well as view various real-time metrics. And similar to other big-name health tech companies, Oura is launching a new research study called the Brain Health Study. Users can opt in to share their data as Oura studies how metrics correlate to cognitive performance.All of this is pretty sensitive information, and given Oura’s controversy last year over its Palantir partnership, the company says it’ll now give users expanded options for deleting their data. A new feature called Time-based Data Deletion will allow users to erase their information from a specific window of time should they wish.The Oura Ring 5 is available for preorder today, starting at $399 for the black and silver colors and $499 for the rest of the colors. It’s expected to ship June 4th. The Brain Health Study is live starting today. The rest of the software updates will roll out in June.Photography by Victoria Song / The VergeFollow topics and authors from this story to see more like this in your personalized homepage feed and to receive email updates.Victoria SongCloseVictoria SongSenior Reviewer, Wearable TechPosts from this author will be added to your daily email digest and your homepage feed.FollowFollowSee All by Victoria SongGadgetsCloseGadgetsPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All GadgetsHands-onCloseHands-onPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All Hands-onReviewsCloseReviewsPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All ReviewsTechCloseTechPosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All TechWearableCloseWearablePosts from this topic will be added to your daily email digest and your homepage feed.FollowFollowSee All WearableMost PopularMost PopularValve raises Steam Deck prices by more than $200Sony’s first RGB TV is a statement pieceSony is offering up to 50 percent off some of our favorite PS5 gamesHere’s how Google is responding to Fitbit users who don’t like the new Health appWin cool gadgets we can’t keep because The Verge has ethicsThe Verge DailyA free daily digest of the news that matters most.Email (required)Sign UpBy submitting your email, you agree to our Terms and Privacy Notice.

The Oura Ring 5 has been released with significant physical and software enhancements, centered around a focus on miniaturization, material quality, and advanced health monitoring capabilities. The new device is 40 percent smaller than its predecessor, reducing its width from 7.9 millimeters to 6.09 millimeters and its thickness from 2.88 millimeters to 2.29 millimeters, resulting in a weight between 2 and 2.69 grams. Although the physical differences are subtle, the reduction is noticeable when worn, offering a slimmer profile on the finger. The device is constructed from titanium and possesses IP68 weather resistance, featuring a coating reported to be less prone to scratching than previous models, and it is offered in a new "deep rose" color option. Furthermore, the battery life has been optimized through reengineered components, allowing the ring to last for six to nine days, addressing the limitation that larger rings often yield longer battery life. The optional charging case has also received an upgrade, now supporting wireless charging and accommodating five full charges.

Despite the physical advancements, the launch introduced some limitations, particularly concerning sizing options and material availability. Oura recommends that potential upgraders consult a new sizing kit because the redesigned components may result in an "in-between" ring size, and the available sizes are limited to 6 through 13, rather than the previous range of 4 through 15. Additionally, the company has not yet offered a ceramic option for the ring.

Beyond the hardware improvements, the Oura Ring 5 incorporates substantial new software features aimed at deeper health analysis. Building upon Symptom Radar, the device now includes Health Radar, a suite of features that monitors nighttime blood pressure and breathing trends, allows for the import of medical records, and includes a partnership with Council AI for a medical chatbot, which requires participation in experimental beta testing. For users focused on metabolic health, the software integrates GLP-1 insights, enabling users to track medication dosages, monitor associated changes, and understand the drug's effect on their metrics, alongside the ability to directly upload lab results and consult the AI chatbot regarding findings.

Fitness tracking in the Oura application has also seen improvements, allowing users to pair third-party heart rate monitors and view various real-time metrics. In an effort to explore cognitive wellness, Oura has launched the Brain Health Study, inviting users to opt in and share health data to research correlations between metrics and cognitive performance. In response to recent scrutiny regarding data privacy, Oura has introduced Time-based Data Deletion, a new feature allowing users to erase their information from a specified time window. The Oura Ring 5 is currently available for preorder starting at $399 for the black and silver colors and $499 for other color options, with an expected shipping date of June 4th.
