Oura’s New Ring 5 Is Smaller and Lighter—and Adds an AI Health Coach | WIRED
Skip to main contentCommentLoaderSave StorySave this storyCommentLoaderSave StorySave this storyTwo years on since the Oura Ring 4, Finnish health tech company Oura is back with a new smart ring—right in time to compete with the other screenless fitness tracker of the moment, the Fitbit Air. The Oura Ring 5 doubles down on the company's minimalist ethos with a smaller ring design, upgraded durability, and—unsurprisingly—a suite of AI-powered wellness features.The Ring 5 is available for preorder today and begins shipping June 4. It starts at $399 in silver and black, while premium finishes—Stealth, Brushed Silver, an updated Gold, and a new Deep Rose color—cost $499. Oura’s subscription pricing remains the same at $6 per month or $70 annually. The Charging Case is also available for preorder in select markets. The ring, charging case, and Oura membership all qualify for HSA and FSA reimbursement in the US.Tiny Ring, Big AmbitionsCourtesy of OuraAt 6.09 mm wide and 2.28 mm thick, Oura's latest ring is 40 percent smaller than the Ring 4, which the company claims makes it the world’s smallest smart ring. The titanium exterior is now coated with a new physical vapor deposition (PVD) to improve scratch resistance, and the ring itself is dustproof and water-resistant up to 100 meters with an IP68 rating.Shrinking the Oura Ring hasn’t come at the expense of performance. Oura says the Ring 5 is more accurate than its predecessor, thanks to LEDs four times more powerful and redesigned sensors positioned closer to the skin for improved signal detection. The ring supposedly incorporates 12 independent signal pathways to refine accuracy across a range of finger shapes and skin tones. Battery life gets a modest boost, too, with Oura claiming between six and nine days per charge, up from the Ring 4’s five-to-eight-day range.Courtesy of OuraOura is also releasing a new portable Charging Case ($99), which can add an extra month of battery life, or roughly five full charges. The case has a button to check its charging status and pairing. It’s also compatible with the new Locate feature rolling out to Gen 2 devices and newer, allowing users to track misplaced rings and charging cases through the Oura app.The Oura AdvisorThe most notable changes arrive on the software side. Oura is positioning the Ring 5 as a proactive health platform, much like how Google is positioning its AI Health Coach at the center of the redesigned Google Health app.Central to that shift is Oura Advisor, the company’s large-language-model-powered assistant that debuted last year, and Oura’s proprietary AI model for women’s health. The company is partnering with Counsel Health to integrate AI-assisted health guidance with access to licensed physicians through Oura Advisor. Via the integration, you can ask health questions, receive personalized guidance, and connect with health care professionals from the app.Fitness tracking is getting an overhaul. A new live activity mode lets users start workouts from the app and view heart rate, pace, and distance in real time through lock-screen widgets, so you don't even have to unlock your phone mid-session. For activities where a smart ring can be uncomfortable, such as powerlifting, the app now supports third-party heart-rate monitors and select devices, so you can continue to capture live workout data without wearing the ring itself. Oura also says its updated Automatic Activity Detection is significantly more accurate than previous generations, particularly for lower-motion exercises like pilates.Courtesy of OuraCourtesy of OuraThen there's Oura's preventive health ambitions: Health Radar, which builds on the Symptom Radar feature introduced in 2024. Health Radar continuously analyzes biometric patterns in the background to flag subtle changes before they become more obvious problems. At launch, Health Radar centers around two new functions: Blood Pressure Signals and Nighttime Breathing.Blood Pressure Signals continuously analyzes biometric trends that may correlate with cardiovascular strain. A new Nighttime Blood Pressure capability monitors whether blood pressure drops appropriately during sleep. Oura says this metric may reveal cardiovascular risks that daytime readings may miss. You can also add cuff readings to provide additional context.Meanwhile, Nighttime Breathing provides a rolling 30-day view of breathing disturbances during sleep to identify changes that could affect sleep quality or signal underlying issues. Earlier this month, Oura announced a partnership with Resmed that offers users with elevated nighttime breathing alerts access to sleep health resources, complete sleep assessments, and the option to connect with independent healthcare providers for potential diagnosis and treatment.Metabolic health is another growing focus. Oura is introducing GLP-1 medication self-management tools that allow users to log and track dosing schedules, side effects, and weight changes. Oura is also expanding its Health Panels feature with Lab Uploads, so you can import blood test results and compare biomarkers over time. In the US, subscribers can connect eligible providers to import diagnosed conditions, medications, and lab results into a Personal Health Record in the app.Courtesy of OuraThe new launch comes with a stronger emphasis on privacy controls, according to Oura. A new time-based Data Deletion feature lets users—across all Oura generations—erase data from specific periods without wiping their long-term history. Members also have more granular oversight with configurable controls over how their data is used and shared with third parties.The Ring 5 is available in sizes 6 through 13, and Oura recommends all consumers, including existing members, use the company’s updated sizing kit before ordering, since the smaller design may fit differently than previous generations. Also new is multi-ring support, allowing users to pair and switch between multiple Ring 4 and Ring 5 devices on a single account at no additional charge.SpecsWeight2 to 2.69 grams (depending on size)MaterialsTitanium with physical vapor deposition (PVD) coatingBattery LifeUp to 9 daysWater ResistanceUp to 100 meters (IP68)Sizes6 to 13ColorsSilver, Black, Stealth, Brushed Silver, Gold, and Deep RoseCompatibilityiOS and AndroidCommentsBack to topTriangleYou Might Also LikeHow to find us: Add WIRED.com to your preferred sources in GoogleHow the Canvas hack threatened thousands of schoolsBig Story: I've covered robots for years—this one is eerily lifelikeOrbs, saucers, and flashes on the moon—here’s what’s in the UFO filesTake our survey: What does “home” mean to you?Boutayna Chokrane is a product writer and reviewer at WIRED, covering consumer products and online trends.
