Oura Ring 5 just dropped — and it’s turning heads. Announced on May 28, 2026, this is the most significant redesign the smart ring has seen in years. If you’ve been waiting to jump into health tracking wearables, or you’re thinking about upgrading from an older model, this is the right moment to pay attention.
This guide covers everything you need to know: design, features, price, who should buy it, and whether it’s worth the upgrade.
What Is the Oura Ring 5?
The Oura Ring 5 is the fifth generation of Oura’s flagship smart ring. It’s a small, titanium ring you wear on your finger 24/7 to track your health — sleep quality, heart rate, activity, stress, blood pressure trends, and much more.
Unlike a smartwatch, there’s no screen. It sits quietly on your finger, collects data around the clock, and sends insights to your phone through the Oura app.
The Ring 5 ships on June 4, 2026, starting at $399.
Design: 40% Smaller Than Before
The biggest headline? Size. Oura calls this the “world’s smallest smart ring” — and the numbers back that up.
- Width: 6.09mm (down from 7.99mm on Ring 4)
- Thickness: 2.28mm (down from 2.88mm)
- Weight: starts at just 2g for smaller sizes
That’s a 40% reduction in overall size compared to the Oura Ring 4. Oura achieved this by redesigning the battery, the sensor architecture, and the internal electronics from scratch.
The result looks and feels much closer to a traditional wedding band. If you found earlier Oura rings bulky or obvious, the Ring 5 is a serious improvement.
Materials and Durability
The Ring 5 is built from aerospace-grade titanium — both inside and outside. It comes with a new physical vapor deposition (PVD) coating that improves scratch resistance compared to previous models.
It’s also rated 100m water resistant, so swimming and showering are no problem.
Color Options
The Ring 5 comes in six finishes:
- Silver ($399)
- Black ($499)
- Stealth ($499)
- Brushed Silver ($499)
- Gold ($499)
- Deep Rose ($499)
The Silver option is the entry-level price. Every other finish adds $100 to the base cost.
Health Tracking: What It Actually Monitors
The Oura Ring 5 tracks over 50 health metrics and insights. Here’s a breakdown of what matters most.
Sleep Tracking
Sleep has always been Oura’s strongest suit, and Ring 5 continues that tradition. The ring tracks:
- Sleep stages (light, deep, REM)
- Total sleep time
- Sleep efficiency
- Resting heart rate
- Breathing rate during sleep
- Body temperature variation
Oura claims its sleep detection now hits 95% accuracy. For a wrist-free device, that’s impressive.
Heart Rate Monitoring
The heart rate sensor in Ring 5 has been rebuilt with more powerful LEDs and better skin contact geometry. Oura claims 99% accuracy for heart rate tracking.
The redesigned sensors also work more reliably across a wider range of skin tones and finger sizes — an issue that has affected some users with earlier models.
Blood Pressure Signals (New)
This is one of the most talked-about new features. The Ring 5 introduces Blood Pressure Signals — a tool that monitors your blood pressure patterns during sleep and can flag potential warning signs of cardiovascular risk.
Important note: this feature is launching in the US, India, and UAE first (starting June 2026). It’s not available everywhere yet.
Nighttime Breathing Analysis (New)
Also new is Nighttime Breathing analysis. The ring detects disruptions in your breathing patterns during sleep — useful context for anyone concerned about sleep apnea or related issues.
This data feeds into the broader Health Radar feature (more on that below).
Activity and Fitness Tracking
The Ring 5 supports:
- Step counting
- Calorie burn estimation
- Activity detection
- VO2 Max estimation
- Cardiovascular Age metric
Live workout tracking is also new. Through a connected phone, you can see real-time pace, distance, and heart rate during runs or workouts.
GLP-1 / Ozempic Tracking (New)
Oura is partnering with health companies to offer GLP-1 medication tracking — a feature aimed at people using drugs like Ozempic or Wegovy. The ring helps track how your body is responding to these medications through biometric signals like recovery, heart rate variability, and activity levels.
This reflects a broader trend: Oura is moving from a fitness tracker into a preventative health platform.
Health Radar: Oura’s New AI Health Layer
Health Radar is the new software layer that sits on top of all the raw data the ring collects. It works in the background, monitoring your biometrics continuously and surfacing patterns worth paying attention to.
Think of it less like a fitness dashboard and more like a quiet health watchdog. It doesn’t just log your data — it looks for deviations and flags things before they become problems.
Health Radar launches with two core features:
- Blood Pressure Signals
- Nighttime Breathing
More capabilities will roll out over time. These software features will also be available to Oura Ring 3 and Ring 4 users — not just Ring 5 owners.
Battery Life
Battery life has improved over the Ring 4:
- Ring 5: 6 to 9 days per charge
- Ring 4: 5 to 8 days per charge
Real-world battery life will vary depending on ring size, usage, and settings. Larger rings tend to have slightly more battery capacity.
Oura is also launching an optional Oura Ring 5 Charging Case (sold separately). It’s made from recycled aluminum, fits in your pocket, and can extend battery life up to one month total — ideal for travel.
Price and Subscription
Here’s the full cost breakdown:
| Item | Cost |
|---|---|
| Oura Ring 5 (Silver) | $399 |
| Oura Ring 5 (all other colors) | $499 |
| Monthly membership | $5.99/month |
The monthly membership unlocks all your health insights, AI features, and Health Radar. Without it, the ring still collects data but you lose most of the value.
This is a $50 price increase over the Oura Ring 4, which started at $349.
Oura Ring 5 vs Oura Ring 4: Is It Worth Upgrading?
Here’s a quick comparison:
| Feature | Ring 4 | Ring 5 |
|---|---|---|
| Width | 7.99mm | 6.09mm |
| Thickness | 2.88mm | 2.28mm |
| Battery life | 5–8 days | 6–9 days |
| Blood Pressure Signals | No | Yes |
| Nighttime Breathing | No | Yes |
| GLP-1 tracking | No | Yes |
| Live workout tracking | No | Yes |
| Starting price | $349 | $399 |
If comfort is your main concern, the Ring 5 is a clear upgrade. The 40% size reduction is not a minor tweak — it’s a fundamentally different wearing experience.
If you’re happy with your Ring 4 and don’t care about the new features, the Ring 4 still works well. Many of the software updates (Health Radar, Blood Pressure Signals, Nighttime Breathing) are rolling out to Ring 3 and 4 devices as well.
Who Should Buy the Oura Ring 5?
Buy it if you:
- Want the most discreet, comfortable health tracker available
- Care about long-term health monitoring, not just step counts
- Are interested in sleep quality, heart health, or recovery
- Found previous Oura rings too bulky
- Take GLP-1 medications and want biometric feedback
Skip it if you:
- Need a GPS watch for running or cycling
- Want a screen with notifications
- Don’t want to pay a monthly subscription
- Are happy with your Ring 4 (most software features will update automatically)

Final Thoughts
The Oura Ring 5 is the most refined version of the Oura Ring yet. The size reduction alone makes it feel like a genuinely new product — not just an incremental update. Combined with better battery life, more accurate sensors, and new health tracking capabilities, it’s a strong package for anyone serious about understanding their body.
It’s not cheap. At $399 plus a monthly subscription, it’s firmly premium. But for what it delivers — 24/7 health tracking in something that looks like a plain ring — there’s nothing quite like it on the market right now.
If you’ve been on the fence, 2026 might be the year to finally try it.
