Oura Ring 5 Review: Slimmer, Longer-Lasting Smart Ring Health Tracking

Verdict: The Best Smart Ring Health Tracker, at a Steep Price

The Oura Ring 5 is a premium smart ring designed for holistic health tracking, combining long-term sleep, activity, stress, and cardiovascular metrics with a jewelry-like form factor you can comfortably wear day and night. At USD 399 (approx. RM1,840) before its required membership, it is both the most refined and the most expensive smart ring in the current market. This is not a casual step-counter; it is aimed at people who want continuous wearable sleep monitoring, stress insights, and advanced vitals like overnight blood pressure trends rather than on-wrist workout stats. If you care about design and comfort and see value in deep health data, the Oura Ring 5 is easy to recommend. If you primarily want exercise tracking for less money, wrist-based options remain better buys.

Design and Comfort: Thinner, More Like Jewelry Than a Gadget

The core reason to pick the Oura Ring 5 over other smart ring health tracking options is its design. The band measures 0.24 inches wide by 0.09 inches thick, making it 40% slimmer than the previous generation’s 0.31 by 0.11 inches. On the finger, that reduction is obvious: the ring feels nearly weightless, sits low enough not to catch on pockets, and stays unobtrusive even when your hand is clenched. The rounded exterior and hidden sensors mean it looks like ordinary jewelry at a glance, with minimal visible tech. According to the review source, “the fifth-gen model is so thin that I often forget I am wearing it, and its elegant, stylish design always catches my eye when I look down.” Built from high-performance titanium and rated IP68 with water resistance down to 328 feet, it balances fashion with durability for all-day wear.

Battery Life: Wear It for Over a Week Without Thinking

Battery life is where the Oura Ring 5 quietly rewrites expectations for ring battery life. Officially, the company estimates six to nine days per charge, already an improvement over the Ring 4’s five to eight days. In real-world testing, it ran for 10.5 days on two separate rundown tests with typical usage, beating both its own estimate and the previous model. That also outlasts the Fitbit Air wristband, which managed 8.5 days in similar testing. This matters because health tracking is most insightful when you never take the device off; having a ring that can cover a full week plus workdays, then recharge during a short break, means fewer gaps in your sleep and vitals history. Given the extra-thin frame, a drop in endurance would have been understandable, but Oura has instead delivered “even more battery life into the petite Oura Ring 5.”

Health and Sleep Tracking: Deep, Daily Insights in the Oura App

The Oura Ring 5 is built for holistic smart ring health tracking rather than gym metrics. It monitors more than 50 health metrics, including daily movement, various exercises, sleep duration and stages, and stress levels. Over time, it builds long-term views of cardio capacity, cardiovascular age, and sleep regularity, turning nightly data into trend lines. New with this generation are overnight blood-pressure monitoring for signs of hypertension, long-term breathing-pattern tracking, and even tools to follow the effects of GLP-1 weight-loss medications. The app’s Today tab surfaces scores for sleep, activity, and stress, and dynamically highlights what matters most at different times of day—your sleep score in the morning, activity in the afternoon if you are behind, or stress if you need to unwind. For users focused on wearable sleep monitoring and overall wellness, this ring-plus-app combination feels more like a quiet health companion than a fitness coach.

Price, Membership, and Market Position: Premium and Subscription-Bound

All this refinement comes with a clear cost. The Oura Ring 5 starts at USD 399 (approx. RM1,840), which is USD 50 (approx. RM230) more than the base Ring 4 that still offers the same tracking features. Core finishes are black or silver, while brushed silver, deep rose, gold, and stealth are available at USD 499 (approx. RM2,300). On top of the hardware, an annual membership of USD 69.99 (approx. RM320) is required to unlock most features in the app. Altogether, this makes it the most expensive smart ring tested, even edging out the Samsung Galaxy Ring at USD 399.99 (approx. RM1,840), which does not require a subscription. In the broader wearable market, wrist-based trackers like the Fitbit Air at USD 99 (approx. RM460) offer better exercise tracking with no mandatory subscription. The Oura Ring 5 is therefore best seen as a high-end wellness investment, not a budget fitness device.
