Oura just made its boldest product move yet. The company announced on Thursday the Oura Ring 5 — described as the smallest smart ring ever offered by any company, coming in 40% smaller than its previous generation while maintaining the same sensing, tracking, and accuracy. It ships from June 4th, priced at $399 for base finishes and $499 for premium options including gold and brushed silver. A portable charging case is available separately for $99.
“We have finally achieved what seems like a real technological miracle,” Oura’s CEO said in an interview. “This is what our members have been asking us for, for years.” The engineering challenge was significant — batteries, electronics, sensors, and geometry all had to be rethought from scratch to fit a dramatically reduced form factor without sacrificing performance. The CEO described wearing a prototype for six months through gym sessions and daily use without even noticing it was there.
More Than a Smaller Ring
The Ring 5 launch arrives alongside a significant expansion of Oura’s health platform — features that will also be available to existing Ring 3 and Ring 4 owners through a software update.
The flagship new capability is Health Radar, an evolution of Oura’s proactive health tracking that monitors biometric signals including body temperature and respiratory rate, sending alerts when significant deviations are detected. Two new additions go further than anything Oura has offered before. Blood pressure pattern tracking during sleep can now flag potential cardiovascular risk indicators before a user is aware of any symptoms. Nighttime breathing pattern monitoring adds another layer of early-warning capability for respiratory conditions.
Oura is also partnering with on-demand healthcare platform Counsel Health to offer AI-enabled medical care directly inside the app. Members in 43 US states will be able to ask health questions, receive personalised advice, and connect with healthcare providers without leaving the Oura platform. The company is also adding improved live activity tracking for running and cycling, and a dedicated GLP-1 insights feature to help users on weight-loss medications track dosing schedules, weight changes, and body composition data alongside their ring’s biometric readings.
The product evolution reflects a company that has moved a long way from its origins as a sleep tracker. Oura has sold over 5.5 million rings since launch and is on track to surpass five million paid subscribers this quarter — a fourfold increase over two years. Revenue has grown at the same rate. The company raised a $900 million Series E funding round last October at an $11 billion valuation and has raised more than $1.5 billion in total. The CEO told reporters late last year that 2026 sales could approach $2 billion. An 80% subscription renewal rate suggests users are staying engaged well beyond the initial purchase.
The Oura Ring 5 represents the clearest statement yet of where the company sees its future — not as a fitness gadget, but as a genuinely medical-grade wearable that happens to fit on your finger.
