Oura has officially opened preorders for the Ring 5, its most compact smart ring to date, with shipping set to begin June 4th. Available at Amazon, Best Buy, Target, Walmart, and Oura's own storefront, the device starts at $399 and represents the most aggressive hardware overhaul the Finnish health-tech company has made in years. The Ring 5 isn't just thinner — it's a fundamentally redesigned platform with new health monitoring capabilities that push it squarely into medical-adjacent territory.
A Dramatically Smaller Form Factor
The headline spec is hard to ignore: the Ring 5 is 40 percent smaller than the Ring 4, achieved through a slimmer profile and lighter overall construction. That reduction isn't cosmetic — it changes how the ring fits and sizes. Oura is offering a free sizing kit with each purchase, and the company is explicit that the new dimensions mean Ring 4 sizing charts no longer apply. The ring ships in sizes 6 through 13 and is compatible with both iOS and Android. Base models arrive in silver and black at $399; premium finishes — gold, stealth, brushed silver, and deep rose — run $499. Every configuration includes a size-matched charger and a USB-C cable, and all variants qualify for HSA and FSA reimbursement in the US.
Nine Days of Battery, a New Charging Case, and Real-Time Workouts
Oura is claiming up to nine days of battery life from a single charge, an improvement over the Ring 4's roughly seven-day ceiling. Alongside the ring, the company is launching a dedicated Oura Ring 5 Charging Case — available for $99 from Amazon, Best Buy, Target, and Oura directly — that adds wireless charging support and can extend total operational time to roughly a month between wall plug-ins. The case features an action button for quick pairing and charge-status checks. On the fitness tracking side, Oura is introducing a live activity mode that delivers real-time workout metrics and heart rate data, a notable gap in prior versions. The Ring 5 also gains support for third-party heart rate monitors, opening the door for more serious athletes who want external sensor data folded into Oura's ecosystem.
"The Ring 5 is 40 percent smaller than its predecessor — but the software story may matter more than the hardware."
Health Radar, GLP-1 Tools, and AI-Assisted Medical Guidance
Oura is making a deliberate push into preventive health with a suite of new software features that accompany the hardware launch. Health Radar is the most clinically ambitious addition: it continuously monitors nighttime breathing and blood pressure patterns, flagging irregularities that could signal developing health concerns. The platform is also rolling out GLP-1 tracking tools tailored to users on weight-loss medications, a nod to one of the fastest-growing patient populations in the US. Perhaps most consequentially, Oura has partnered with Counsel Health to integrate AI-assisted medical guidance directly into the app — a move that positions the ring less as a fitness tracker and more as a continuous health companion. A new Locate feature rounds out the software update, letting users find a misplaced ring or charging case through the app. The core membership that unlocks these features remains $5.99 per month or $69.99 annually.
Oura is betting that shrinking the hardware while expanding the health intelligence layer is the formula to outpace Garmin, Apple, and Samsung in the premium wearables market. With preorders live across every major US retailer as of May 28th and units shipping June 4th, the Ring 5 arrives at a moment when consumer appetite for passive, always-on health monitoring has never been higher. Whether the improved accuracy claims and new clinical-grade features hold up under real-world scrutiny remains to be tested — but on paper, this is the most compelling version of Oura's vision yet.
