Oura Ring 5 review: Refined hardware keeps the brand ahead of the competition

I must confess, the Oura Ring 5 launch caught me by surprise. I’m used to the company tweaking its software and features for a while before moving on to launch new hardware. After all, there was a nearly three-year gap between the release of the Oura Ring Gen 3 and Oura Ring 4.

The new smart ring arrived less than two years after its predecessor (a year and eight months, to be precise), marking a much faster release cycle than we're used to from Oura. As a result, this is more of an evolutionary update than a revolutionary one, with a handful of notable hardware refinements rather than a wholesale redesign.

All of this makes reviewing the Oura Ring 5 something of a balancing act. With relatively few new features, I didn't need months to get familiar with the hardware or software. The harder part was deciding whether those refinements are enough to justify a new generation, especially in a smart ring market that's become far more competitive since the Ring 4 launched.

The good news is that the Oura Ring 5 is still the best smart ring on the market, but if you have the Oura Ring 4 (or the Oura Ring 4 Ceramic) and don’t mind its ‘heft’, there is no need to rush and order the new ring. What are the new features and how do they affect the user experience? Let’s find out.

Oura Ring 5 review

Price and availability

The Oura Ring 5 was announced in May 2026 and is now available to buy at Oura, starting at £399 / $399 / €429 / AU$649 for Silver and Black finishes, and rising to £499 / $499 / €529 / AU$799 for premium colours, including Gold, Stealth, Brushed Silver, and Deep Rose.

This makes the new wearable more expensive than its predecessor, which retailed for £349 / $349 / €399 / AU$569 at launch. These days, you can find plenty of deals on both the Oura Ring 4 and the Oura Ring 4 Ceramic, making them a lot more affordable.

Even though Oura’s products can be used without a subscription, you’ll need Oura Membership to enjoy the full benefits of the system. It costs £5.99 / $5.99 / €5.99 / AU$9.99 a month or £69.99 / $69.99 / €69.99 / AU$109.99 annually. Oura remains the only major smart ring brand to require a membership from its users.

Design and build quality

In the intro, I mentioned a “handful of notable hardware refinements,” which might have undersold the Oura Ring 5. The new ring is 40% smaller than the Oura Ring 4 and looks and feels very much like a standard jewellery ring when worn.

The Oura Ring 5 is 6.09mm wide and 2.28mm thick across its full size range, which makes especially larger models, including my size 12, look rather dainty. The ring comes in six colours, including two basic colours (Silver and Black), and four premium finishes (Brushed Silver, Stealth, Gold and Deep Rose).

The last two are either new (Deep Rose) or redesigned (Gold). I opted for the Deep Rose model to see how it looks in real life, and, more specifically, how it compares to the Rose Gold colourway it replaces. I’d say it looks more like a deep gold, slightly darker than your average gold jewellery but without the pink undertone of the Rose Gold version.

The Oura Ring 5 is not only slimmer but also a lot lighter than the Oura Ring 4. The weight range is 2.0–2.7g – compare it with the Oura Ring 4’s 3.3–5.2g. It’s worth noting that the new model comes in fewer sizes (6–13 vs 4–15). I’m sure a few Oura Ring users with larger / petite hands will be disappointed to hear this. The majority of Oura users will probably be fine, though.

The company redesigned the sensor paths, reducing the number from 18 to 12. Despite the fewer optical paths, the new ring is said to provide more accurate readings, thanks to the brighter LEDs and – I assume – a refined algorithm that analyses the data.

One thing I forgot to mention (and glad to see and feel the return of) are the notches inside the ring. The Oura Ring 4 was slimmer than the Oura Ring 3 and reduced the bumps to almost nothing.

Now that the Oura Ring 5 is even slimmer, the notches are back, making it much easier to rotate the ring into the correct position without looking. The bumps are nowhere near as pronounced as on the Oura Ring 3, but detectable enough to help you find how the ring should sit on your finger.

The brand says the Oura Ring 5's revised PVD coating is more durable than before, and my experience backs that up. Despite wearing it during kettlebell workouts, the ring emerged without any visible scuffs or scratches.

Features

Oura announced a few new features with the launch of the Oura Ring 5, but most aren’t available in all markets yet due to regulatory hurdles in certain countries. Chiefly among these is Health Radar, which continuously analyses multiple biometric signals to spot changes in your physiology before you notice symptoms yourself.

Health Radar builds on the older Symptom Radar feature but is much broader in scope. At launch, it offers Blood Pressure Signals, which examine long-term patterns that may indicate elevated cardiovascular strain, and Nighttime Breathing, which provides a rolling 30-day view of breathing disturbances during sleep.

It’s somewhat risky for Oura to offer blood pressure-related health features, given that Whoop got in trouble with the FDA for rolling out a similar feature in the US, but brand representatives were confident that Oura's approach is different. Living in the UK, I haven’t been able to test Health Radar yet.

Oura Advisor, the company’s AI chatbot, is now said to be more helpful. Admittedly, the brand focuses on women’s health improvements, but the bot can also give you more usable answers about other health metrics. I asked it why the app said I fell asleep too quickly (3-minute latency), given that I have a steady sleep schedule and excellent sleep scores, and it said there is nothing wrong with me. Thanks!

One area where Oura’s ecosystem has some serious catching up to do is activity tracking. Passive tracking is excellent, and the algorithm will recognise a bunch of popular sports, but historically, Oura Ring hasn’t been anyone’s first choice to track runs with. Now, the app can provide real-time heart rate and pacing feedback on runs via a smartphone widget.

This is commendable, but more of a first step rather than a replacement for Garmin watches. Of course, Oura never claimed it was coming after running watches, but the fact that the company now offers live tracking shows it’s aware of its system's shortcomings.

I imagine most Oura users run with their phones, so having access to live workout data is handy. However, the ring + smartphone setup won’t replace a watch for ‘proper’ training, not to mention the lack of training data, something the Oura ecosystem can’t provide.

As for passive health tracking such as sleep, the Oura Ring 5 is still my top choice. Stress tracking could be better (I ranted about this before), but even that issue won’t push the ring off my finger. There is also the community element; my wife always wants to know how our sleep compares and how many calories we burned during the same walk, for example, which makes me want to wear the ring.

As for accuracy, which Oura claims has improved with the fifth-generation ring, I found it difficult to notice any meaningful difference, purely because the Oura Ring 4 is pretty accurate for sleep tracking as is. Workout tracking is accurate enough, but as I mentioned above, only basic fitness data is being collected, which isn’t much to go on. The ring feels accurate for what it’s worth.

Battery life and charging

The company claims the Oura Ring 5 can last up to nine days on a single charge, depending on ring size and usage, and my experience suggests that's a realistic estimate.

Starting from a full battery, the ring still had 15% charge remaining after almost nine days of continuous wear, including 24/7 health tracking, sleep monitoring and workout logging.

While I didn't let it run completely flat (the app would prompt you to charge when the battery hits 15%), the results indicate the Ring 5 is more than capable of matching Oura's official figures under typical day-to-day use.

Better still, charging is remarkably quick. During testing, the battery climbed from 15% to around 50% in just 25 minutes, making it easy to top up while showering or getting ready in the morning rather than leaving it on the charger overnight.

Verdict

The Oura Ring 5 is an easy product to recommend, but perhaps not for the reasons Oura would like. It isn't a dramatic leap over the Ring 4, nor does it fundamentally change what the Oura ecosystem offers.

Instead, it refines an already excellent formula with a noticeably smaller and lighter design, a more durable finish and slightly longer battery life, all while retaining the outstanding sleep and recovery tracking that has made Oura the benchmark for smart rings.

Most of the headline software features are also rolling out to older rings, meaning existing Ring 4 owners aren't missing out on much. If you're happy with your current ring, there's little reason to upgrade, especially given the higher asking price and ongoing membership fee.

However, if you're buying your first smart ring, or upgrading from an older generation, the Oura Ring 5 is the one to get. No rival combines comfort, polished hardware, insightful health tracking and a mature app ecosystem quite as well.

Activity tracking still lags behind dedicated sports wearables, and the subscription remains a sticking point, but neither detracts from the fact that this is currently the most complete smart ring on the market.
