Oura just dropped the Ring 5 on May 28, 2026 and it might be the most important wearable launch of the year. Not because it reinvents health tracking, but because it quietly fixes every single reason you weren't already wearing a smart ring. It's smaller, more accurate, longer-lasting, and now comes packed with features that rival full-blown medical devices. Let's break it all down.

First Impressions: This Doesn't Look Like a Tracker Anymore
The biggest shift with the Oura Ring 5 is one you notice immediately: it looks like a ring. Not a gadget, not a fitness band, not a medical device a ring.
At just 6.09mm wide and 2.29mm thick, it's 40% smaller than the Ring 4. That's not a minor tweak. Oura completely redesigned the mechanical, electrical, optical, battery, and sensing architecture to get there. The result is something that sits on your finger like a wedding band, disappears into daily life, and tracks your health around the clock without anyone knowing.
Early hands-on impressions from reviewers confirm the difference is immediately noticeable. One reviewer noted it looks like jewelry now not a wearable which will open Oura up to an entirely new audience that found previous generations too bulky.
Available finishes: Silver and Black (base, $399) and Gold, Stealth, Brushed Silver, and Deep Rose (premium, $499).
What's New in Oura Ring 5
1. 40% Smaller Without Sacrificing Battery
This is the headline. Getting 40% smaller while maintaining the same ~1-week battery life (6–9 days vs. Ring 4's 5–8 days) required a ground-up engineering overhaul. Battery life actually improved despite the smaller chassis.
2. 12-Signal Sensing Architecture
Oura has completely rebuilt the sensing system with precision-engineered sensor domes for better skin contact, more powerful LEDs, and 12 signal pathways all designed to deliver greater accuracy across a wider range of finger types and skin tones. This is a meaningful step forward in inclusivity and reliability.
3. Blood Pressure Signals During Sleep
This is the headline health feature. The Ring 5 can now detect blood pressure patterns during sleep, which Oura says can flag warning signs of cardiovascular risk. This is especially significant for users who don't regularly monitor their blood pressure.
4. Nighttime Breathing Analysis
Building on its existing sleep tracking, the Ring 5 now monitors breathing disturbances during sleep a key indicator of conditions like sleep apnea and overall respiratory health.
5. GLP-1 Insights
Oura is one of the first wearable companies to address the GLP-1 medication trend directly. The Ring 5 (and existing Gen 3+ rings) will offer dedicated tracking insights for users on medications like Ozempic and Wegovy helping them monitor how their bodies respond over time.
6. Health Radar
Oura's revamped proactive health feature continuously monitors key biometric signals body temperature, respiratory rate, and more and alerts users when it detects significant deviations. Think of it as a personal early-warning system.
7. AI-Powered Medical Guidance via Counsel Health
In partnership with Counsel Health, Oura is launching on-demand, personalized AI-enabled medical guidance directly in the app. This moves Oura from being a tracker to being something closer to a preventive health platform.
8. Live Activity Tracking
For fitness users, the Ring 5 now supports real-time pace, distance, and workout tracking for running, cycling, and strength training viewable directly from your phone during the workout.
9. Women's Health Updates
New menopause insights and hormonal birth control tracking have been added, with global availability from June 4, 2026.

Performance & Accuracy
Oura has always led the smart ring category in sleep tracking accuracy and Ring 5 pushes that further. The 12-pathway sensor system addresses a long-standing criticism: inconsistent readings on different skin tones and finger shapes. The redesigned sensor domes improve contact consistency, which translates directly into more reliable heart rate, HRV, SpO₂, and temperature readings.
The blood pressure trend detection is new territory for Oura. It's worth noting this is pattern-based and intended as an early signal not a replacement for a clinical blood pressure monitor. But for daily awareness and trend detection, it's a genuinely useful addition.
| Metric | Score |
|---|---|
| Sleep Tracking | 9.8 |
| Heart Rate / HRV | 9.5 |
| Activity Tracking | 8.7 |
| Blood Pressure Signals | 8.2 (new feature, promising) |
| Battery Life | 9.4 |
| Comfort & Wearability | 9.9 |
| App & Insights | 9.0 |
| Value for Money | 8.5 |
Oura Ring 5 vs. Ring 4: Should You Upgrade?
| Oura Ring 4 | Oura Ring 5 | |
|---|---|---|
| Size | 7.99mm × 2.88mm | 6.09mm × 2.29mm (40% smaller) |
| Battery | 5–8 days | 6–9 days |
| Blood Pressure | ✗ | ✓ |
| Nighttime Breathing | Limited | ✓ Enhanced |
| GLP-1 Tracking | ✗ | ✓ |
| Live Activity Tracking | ✗ | ✓ |
| Health Radar | Basic | ✓ Expanded |
| Price | $349 | $399 |
Verdict on upgrading: If you're on Ring 4, the upgrade is compelling but not urgent. The size difference alone may be enough for users who found Ring 4 slightly bulky. If you're on Ring 3 or older or new to Oura the Ring 5 is the definitive version to buy.
Oura Ring 5 vs. The Competition
The smart ring market has heated up significantly. Samsung Galaxy Ring, RingConn Gen 3, and Ultrahuman Ring Pro are all credible alternatives. Here's how Oura stacks up:
- vs. Samsung Galaxy Ring: Samsung has the advantage of deep Galaxy ecosystem integration. Oura wins on health depth, accuracy, and now with Ring 5 design.
- vs. RingConn Gen 3: RingConn is subscription-free, which is a big deal for budget-conscious buyers. But Oura's health analytics, AI insights, and clinical partnerships are in a different league.
- vs. Ultrahuman Ring Pro: Ultrahuman is also subscription-free and excellent for fitness tracking. Oura's sleep science and medical-grade feature set remain the gold standard.
Pros
- 40% smaller actually looks like jewelry now
- Battery life improved despite smaller size (6–9 days)
- Blood pressure trend detection during sleep
- 12-pathway sensor system with better accuracy across skin tones
- GLP-1 medication insights a first in the smart ring category
- Live activity tracking finally arrives
- AI-powered on-demand health guidance via Counsel Health
- New women's health features: menopause + birth control tracking
- Six beautiful finish options
Cons
- Requires ongoing Oura membership subscription (monthly cost)
- • The $399 base price is a step up from Ring 4's $349.
- The blood pressure feature is trend-based, not a clinical measurement.
- No GPS on-device (relies on phone)
- Not compatible with older Oura Ring generations (Gen 1/2)
Who Should Buy the Oura Ring 5?
The Oura Ring 5 is for anyone who wants serious health data without the screen fatigue of a smartwatch. It's ideal for:
- Health-conscious users who want sleep, HRV, and cardiovascular trend data without wearing a watch to bed
- GLP-1 medication users who want a dedicated tracker for how their body is responding
- Women looking for the most comprehensive hormonal health tracking in a wearable
- Minimalists who want a device that disappears on their finger
- Existing Oura Ring 3 users Ring 5 is a major generational leap worth the upgrade.
If you hate subscriptions and primarily want step/activity tracking, a Samsung Galaxy Ring or RingConn Gen 3 might suit you better at a lower total cost. But for depth of health insights, nothing in the smart ring category comes close.
Final Verdict
The Oura Ring 5 is the best smart ring ever made and arguably the most refined health wearable of 2027. Oura took what was already a category leader, made it 40% smaller, added genuinely meaningful new health features, and improved battery life. That's a rare combination.
At $399, it's not cheap. The subscription adds to the cost. But if you're serious about tracking your health over time sleep quality, cardiovascular signals, recovery, and metabolic health the Oura Ring 5 is worth every rupee (or dollar).
