What Oura Ring 5 Is and Why Its New Design Matters
Oura Ring 5 is a health tracking ring that combines a dramatically thinner physical design with upgraded sensors and app-based insights to improve long-term sleep, activity, and recovery monitoring on your finger. The headline change is size: Oura says the new ring is 40% smaller than Oura Ring 4, with thickness cut to 2.28 mm and width reduced to 6.09 mm. That makes it much closer to everyday jewelry than earlier, bulkier generations of smart rings. At the same time, Oura claims better battery life, extending from a previous 5–8 days to 6–9 days between charges. In a category where comfort and discretion often decide whether people wear devices every day, the Oura Ring 5 design aims to solve one of the biggest complaints about health tracking wearables: feeling like a gadget instead of a ring.
Thinner Than the Competition: How the New Design Competes
The new Oura Ring 5 design is not only slimmer than Oura’s previous models, it is positioned as the thinnest health tracking ring on the market. One reviewer notes that earlier models measured about 8 mm wide, compared with roughly 7 mm for RingConn; at 6 mm, Oura Ring 5 undercuts both. That change matters because smart rings have long felt chunky compared with traditional jewelry. According to press materials cited by Lifehacker, Oura is confident this thinner profile will set the standard for thin wearable technology in its category. At the same time, Oura has tweaked the interior shape. After smoothing the inner surface on Ring 4, Ring 5 brings back smaller sensor bumps to keep the electronics closer to the skin, which should enhance signal quality without adding bulk.
Sensor Upgrades and a Redesigned Health Tracking Architecture
Oura Ring 5 is not only slimmer; it also introduces a new sensing architecture designed to raise accuracy in core smart ring features. Oura describes this as its “most accurate generation yet,” pairing more powerful LEDs with a more efficient sensor layout and optimized placement closer to the skin. The ring uses 12 optimal signal pathways to maintain performance across different fingers and skin tones. Oura reports a 12% improvement in overnight HRV accuracy compared with Oura Ring 4 for the average member. Workout tracking sees a bump too, with a 24% improvement in signal quality for exercise heart rate, translating to a 19% increase in accuracy for activities like running, cycling, and walking. Taken together, these hardware and algorithm changes aim to make the thinner form factor an upgrade in reliability rather than a compromise.
New App Health Radar: From Sleep Trends to Risk Alerts
To match the slimmer hardware, Oura is rolling out new app-based health features that try to turn raw data into actionable guidance. The standout is Health Radar, which watches for unusual patterns in your biometrics and flags potential concerns. Lifehacker reports that Health Radar is designed to alert you when readings suggest signs of high blood pressure or “breathing disturbances,” Oura’s term that points toward possible sleep apnea. The app will not diagnose conditions, but it can nudge users to talk with a professional if trends look off. This builds on the existing Symptom Radar and recent partnerships with sleep technology providers like ResMed. Oura is also adding richer workout metrics inside the app, aiming to make the health tracking ring more useful for people who want to see detailed exercise data without moving to a full smartwatch.
Pricing, Subscription, and the Value Case for Ring 5
Oura Ring 5 comes with a noticeable price increase but makes its case through thinner design and expanded smart ring features. Droid-Life notes that the lowest-priced model is Silver at USD 399 (approx. RM1,860), while other colors such as Black, Stealth, Brushed Silver, Gold, and Deep Rose cost USD 499 (approx. RM2,325). Lifehacker lists Silver and Black at USD 399 (approx. RM1,860) and all other finishes at USD 499 (approx. RM2,325), with improved scratch resistance on the metallic options. As before, full access to insights requires an Oura membership at USD 5.99 (approx. RM28) per month or USD 69.99 (approx. RM325) per year. With the thinner Oura Ring 5 design, longer battery life, and new Health Radar, the question becomes whether users see enough added comfort and intelligence to justify higher hardware and ongoing subscription costs.
