What the Oura Ring 5 Is and Why Its Thin Design Matters
The Oura Ring 5 is a next-generation wearable health tracking smart ring that combines an ultra-thin case with upgraded sensors and new app-based health features to improve comfort, accuracy, and long-term wearability. Oura has rebuilt the case to make it 40% smaller than the Oura Ring 4, shrinking thickness to 2.28mm and width to 6.09mm. That shift moves the Oura Ring 5 into true thin smart ring territory, closer to conventional jewelry than tech gadgetry. At the same time, the redesigned sensing architecture aims for greater reliability rather than compromise. Oura claims more powerful LEDs, improved sensor placement closer to the skin, and 12 signal pathways help deliver more consistent readings across different fingers and skin tones, while also boosting overnight HRV accuracy and workout heart rate performance.
Comfort, Wearability, and the Return of Sensor Bumps
Oura Ring 5’s extreme thinness addresses one of the biggest complaints in this category: smart rings often feel bulky compared to traditional jewelry. Oura says the new ring is only 6.09mm wide and 2.28mm thick, making it smaller than both its own Oura Ring 4 and many rivals in any smart ring comparison. This slimmer profile should translate into better all-day wear, from typing to weightlifting, where thicker rings can pinch or snag. To maintain reliable contact with the skin, Oura is reintroducing smaller interior sensor bumps after smoothing them out in the previous generation. The company is also tightening the size range to US ring sizes 6 through 13 and recommending a fresh sizing kit, which signals that fit precision is more important than ever for the new sensing layout and comfort-focused Oura Ring 5 design.
Sensor Upgrades, Battery Gains, and Accuracy Claims
Under the slimmed-down shell, the Oura Ring 5 focuses on measurable performance gains rather than flashy hardware. According to Oura’s data, the redesigned architecture delivers 12% more accurate overnight HRV readings than the Oura Ring 4 for the average member. The company also reports a 24% improvement in signal quality for workout heart rate, which leads to a 19% accuracy increase for activities like running, cycling, and walking. More powerful LEDs and 12 optimized signal pathways aim to handle different fingers and skin tones more consistently, while battery life is rated at 6–9 days compared with the previous 5–8 day range. Together, these changes signal that thin does not have to mean fragile or underpowered, and they show how the Oura Ring 5 design attempts to balance minimal bulk with reliable daily health metrics.
New Health Features in the App Ecosystem
Alongside the hardware redesign, Oura is expanding its wearable health tracking features inside the app. Detailed workout metrics are now more accessible, which could make the ring a more viable option for users who previously relied on watches or chest straps for exercise data. A new Health Radar feature monitors patterns in your biometrics and flags when something looks off, such as signs that could indicate high blood pressure or breathing disturbances linked to sleep apnea. Oura stresses that the app does not diagnose conditions; instead, it prompts users to seek professional evaluation if unusual trends appear. The company is also layering in tools for people on GLP‑1 medications, including weight, dosage, and side-effect tracking. These additions help the thin smart ring feel less like a standalone gadget and more like part of a broader, proactive health platform.
Pricing, Shipping, and the Competitive Smart Ring Landscape
Oura is positioning the Oura Ring 5 as a premium device, with the lowest-priced Silver model set at USD 399 (approx. RM1,870) and other finishes such as Black, Stealth, Brushed Silver, Gold, and Deep Rose at USD 499 (approx. RM2,340). One quotable detail from Oura’s materials is that “the new Oura Ring 5 is 40% smaller than the Oura Ring 4,” which highlights how aggressively the company is pursuing thinness. The subscription model continues at USD 5.99 (approx. RM28) per month or USD 69.99 (approx. RM330) per year to unlock full features. Shipping begins the week of announcement, with units going out from June 4. In a market where smart rings have often felt like chunky proofs of concept, Oura Ring 5’s slimmer profile and accuracy claims may pressure competitors to match its comfort, finish quality, and integrated health software.
