Oura Ring 5 Shrinks 40% While Doubling Down on Health

Verdict: The Best Wellness Smart Ring, With Clear Caveats

The Oura Ring 5 is a compact fitness ring and health tracking wearable that shrinks Oura’s smart ring design by about 40% while preserving its titanium build, long battery life, and research-grade monitoring of more than 50 health metrics for everyday wellness users. At USD 399 (approx. RM1,850) plus an ongoing membership, it is a premium purchase aimed at people who care more about sleep, recovery, and stress than step counts or hardcore training plans. In that lane, it is excellent: the thinner band feels like jewelry, the data is trustworthy, and the companion app’s new proactive tools make the metrics easier to use. If you want a screenless wellness tracker that you can forget you are wearing, this is the one to beat. The catch is price, subscription, and modest workout tracking, which make it a poor value for casual step-trackers or dedicated athletes.

Design: 40% Smaller, 2-Gram Titanium, and Finally Jewelry-First

Oura’s main story this generation is physical, not digital: the Ring 5 is roughly 40% smaller than the Ring 4, measuring 0.24 inches wide by 0.09 inches thick compared with 0.31 by 0.11 inches before. The titanium construction still feels premium, and the finish held up well during daily wear and even on a hike that involved scrambling over rocks. Reviewers repeatedly noted that the new design feels noticeably less bulky during everyday tasks like typing, carrying groceries, or climbing into bed, to the point where they sometimes checked whether they had remembered to put it on. One called it “the first smart ring that actually feels like a piece of jewelry I’d buy,” praising how often they forgot they were wearing it. The curved exterior looks like a standard band at a glance, while a small white notch on the inner side helps users orient the infrared LEDs properly against the finger. Size range is narrower (6–13 instead of 4–15), so a fresh sizing kit is strongly recommended before ordering.

Battery Life and Accuracy: Set-and-Forget Performance

Oura Ring 5’s smart ring battery life matches the discreet form factor. Officially, the ring is rated for six to nine days per charge depending on usage, up from five to eight days for Ring 4. In testing, it exceeded that estimate, lasting about 10.5 days in two separate rundown tests with typical use, which allows many users to charge only about once a week. One reviewer described the experience as “set-and-forget,” often topping up the ring during a shower and not thinking about battery otherwise. Despite the size reduction, the smaller hardware does not hurt accuracy: overnight heart rate tracking lined up closely with trusted reference devices night after night, and HRV trends were similarly reliable. Sleep stages were among the most accurate that testers had seen, lending weight to Oura’s claim of research-grade monitoring across more than 50 metrics. For a compact fitness ring without a screen, this combination of longevity and trustworthy data is a major part of the appeal.

Health Radar and Metrics: Wellness-First, Not Workout-First

The Oura Ring 5 is a wellness tracker first, not a workout tracker, and it performs best when you use it that way. Under the hood are red and green infrared LEDs for heart rate, HRV, SpO2, and respiratory rate, plus skin temperature sensors and an accelerometer to track movement and sleep. According to Oura, the Ring 5 follows more than 50 health metrics, spanning daily activity, exercise bouts, sleep duration and stages, and stress signals. The companion app now adds Health Radar, which bundles proactive features like Blood Pressure Signals, expanded long-term breathing-pattern measurements, and overnight blood-pressure checks into a single view of emerging trends. That makes the ring especially useful for people who want early signs of overtraining, illness, or chronic stress rather than simple step goals. However, the same reviewers noted it is not ideal as an athlete’s primary fitness tracker, and wrist-based devices at lower prices still offer superior workout analytics and in-session coaching.

Price, Membership, and Real-World Trade-Offs

The Oura Ring 5 is an expensive compact fitness ring. The base model starts at USD 399 (approx. RM1,850), with some finishes costing USD 499 (approx. RM2,300), and it requires a USD 69.99 (approx. RM320) annual membership to access most features in the app. That makes it the priciest smart ring reviewers have tested, even compared with rival rings that do not charge a subscription. Cheaper alternatives exist: the previous Ring 4 now sells from USD 349 (approx. RM1,620) and offers the same tracking features, while wrist-based fitness bands at around USD 99 (approx. RM460) deliver better exercise monitoring without mandatory fees. The lack of an included portable charging case is another sore point for frequent travelers. On the other hand, for users whose main priorities are sleep, stress, and recovery, and who care deeply about wearing something that looks and feels like jewelry, the Ring 5’s design refinement and extended battery life are meaningful everyday upgrades. If you already own and like Ring 4, though, the leap is more about comfort than new capabilities.
