The smart ring world just got a major shake-up. On May 28, 2026, Oura officially unveiled the Oura Ring 5 — its most ambitious wearable yet — and it is already turning heads. Smaller than ever, packed with clinical-adjacent health features, and available to pre-order right now, the Ring 5 is shaping up to be a landmark moment for consumer health technology. Here is everything you need to know.
What Is the Oura Ring 5?
The Oura Ring 5 is the fifth-generation smart ring from Finnish health-tech company Oura Health. Announced on May 28, 2026, and set to ship on June 4, 2026, the Ring 5 arrives far sooner than analysts expected — many had predicted a late 2027 release. Oura is billing it as the “world’s smallest smart ring,” and with a redesigned titanium body, upgraded sensors, and a brand-new health monitoring platform called Health Radar, it is more than just a cosmetic refresh.
Oura Ring 5 Design: 40% Slimmer Than Its Predecessor
Perhaps the biggest headline is the size. The Oura Ring 5 is 40% smaller overall than the Ring 4, measuring just 6.09mm wide and 2.28mm thick — down from 7.90mm and 2.88mm on the previous model. The lightest sizes start at just 2 grams, giving the Ring 5 the look and feel of an ordinary wedding band rather than a bulky fitness tracker.
The outer surface features a slightly more curved profile, and the transition to the synthetic resin inner band is noticeably more seamless. Six finish options are available: Silver, Black, Brushed Silver, Gold, Stealth, and the all-new Deep Rose. The design shift is deliberate — Oura has been steadily positioning its rings as luxury jewellery as much as health devices, a strategy backed by celebrity fans including Prince Harry, Jennifer Aniston, Gwyneth Paltrow, and Mark Zuckerberg.
Oura Ring 5 Health Features: Hypertension and Sleep Apnea Detection
This is where the Ring 5 makes its boldest leap forward. Oura is introducing Health Radar, an upgrade to its existing Symptom Radar platform, with two powerful new capabilities:
1. Blood Pressure Signals (Hypertension Detection) The Ring 5 does not measure blood pressure the way a traditional arm cuff does. Instead, it uses its LED sensors to track changes in blood flow and blood vessel behaviour that are correlated with high blood pressure — a condition that affects hundreds of millions of people worldwide and often goes undetected for years. This Blood Pressure Signals feature is available in the US, India, and UAE starting June 2026.
2. Nighttime Breathing (Sleep Apnea Detection) The Ring 5 uses its sensor suite to monitor blood oxygen levels during sleep. Significant drops in blood oxygen can indicate breathing disturbances consistent with sleep apnea. Users receive a 30-day view of their nighttime breathing patterns, helping them identify trends over time. If the ring detects concerning patterns, it can refer users to medical professionals — a collaboration made possible through Oura’s partnership with ResMed, a global leader in sleep health.
As Oura’s Chief Medical Officer Dr. Ricky Bloomfield explained: many people live for years with unrecognized sleep and breathing issues, and by pairing continuous insights with expert sleep partnerships, the Ring 5 gives users clearer tools to spot when something might be off and to access care more easily.
Oura Ring 5 Battery Life and Charging
Despite being 40% smaller, the Oura Ring 5 still manages to deliver up to seven days of battery life — broadly in line with the Ring 4 — thanks to more efficient internals and optimized power draw. Oura achieved this partly by reducing the size of the battery pack while improving energy efficiency.
A brand-new wireless charging case is available as an optional accessory for $99. The case can hold up to four full charges for the ring, making it ideal for travel. It is made from recycled aluminium, is splash-resistant, and charges via USB-C.
Oura Ring 5 Price and Availability
The Oura Ring 5 is available for pre-order now, with shipping beginning June 4, 2026. Pricing is as follows:
- $399 / £399 / €429 — Silver and Black finishes
- $499 / £499 / €529 — Brushed Silver, Gold, Stealth, and Deep Rose finishes
This represents a $50 price increase over the Oura Ring 4, which launched at $349. The ring is available in sizes 6 to 13 and requires an Oura Membership subscription at $5.99/month to access the full suite of health metrics and insights.
Oura Ring 5 vs Ring 4: What Has Actually Changed?
| Feature | Oura Ring 4 | Oura Ring 5 |
|---|---|---|
| Width | 7.90mm | 6.09mm |
| Thickness | 2.88mm | 2.28mm |
| Starting Price | $349 | $399 |
| Battery Life | ~8 days | ~7 days |
| Blood Pressure Monitoring | No | Yes (Health Radar) |
| Sleep Apnea Detection | Basic | Enhanced (30-day view) |
| Charging Case | Sold separately ($99) | Sold separately ($99) |
| Colours | 6 options | 6 options (new Deep Rose) |
The Ring 5 also brings improved sensor accuracy for overnight heart rate, workout heart rate, and overall signal quality, along with live workout tracking and improved automatic activity detection for over 40 activity types.
AI-Powered Health Insights with Health Radar
The new Health Radar platform goes beyond raw data collection. It uses AI-powered health insights to analyze the more than 50 biometrics the ring continuously tracks — including sleep quality, stress levels, physical activity, skin temperature, heart rate variability, and menstrual cycle monitoring — and surfaces personalised, actionable recommendations. This AI insight layer is one of the most significant software upgrades Oura has brought to a new device.
Oura Health Records: Connecting with Your Doctor
A new feature called Oura Health Records allows members to connect eligible healthcare providers to import diagnosed conditions, medications, lab results, and more directly into the Oura app. This turns the Ring 5 into a genuine bridge between everyday wellness tracking and formal medical care. Note that this feature is currently available in 43 US states only.
Oura Ring 5 vs the Competition
The Ring 5 launches into an increasingly competitive smart ring market. The Samsung Galaxy Ring ($399) offers no subscription fee and deep integration with Galaxy phones. The RingConn Gen 2 ($299) boasts a 12-day battery with zero monthly fees. And Ultrahuman’s Ring Pro has been making inroads at a similar price point.
Oura’s answer to all of this is simple: depth. No competitor currently offers the combination of blood pressure signals, sleep apnea detection, AI health insights, healthcare provider integration, and the brand prestige that comes with an $11 billion valuation and a global celebrity following. The Ring 5 is not the cheapest option — but it may well be the most capable one.
Who Should Buy the Oura Ring 5?
The Oura Ring 5 is ideal for:
- Health-conscious individuals who want clinical-adjacent insights from a discreet, comfortable device
- People at risk of hypertension who want passive, continuous monitoring between doctor visits
- Anyone concerned about sleep quality, including potential sleep apnea sufferers
- Frequent travellers who will appreciate the new portable charging case
- Fitness enthusiasts who want accurate workout tracking without wearing a bulky smartwatch
If the $399 starting price plus the $5.99/month subscription is a stretch, the Oura Ring 4 remains an excellent alternative at a discounted price now that the Ring 5 has launched.
Final Verdict: Is the Oura Ring 5 Worth It?
The Oura Ring 5 is a meaningful evolution, not a revolution — but it is exactly the right kind of evolution. By making the hardware significantly smaller and more comfortable while adding genuinely useful health detection features for hypertension and sleep apnea, Oura has strengthened its position as the premium choice in the smart ring category. The integration of AI-powered insights and healthcare provider connectivity pushes the Ring 5 firmly into territory that no other smart ring has yet occupied.
If you have been on the fence about smart rings, or if you are upgrading from an older Oura model, the Ring 5 makes a compelling case for itself.
