Oura Ring 4 review: premium sleep tracking, premium price

Is the OURA Ring 4 worth buying? Yes, if you want a discreet sleep and recovery tracker and are happy to pay £349 for a ring-sized wearable. The current price is £349.00, which is also the lowest ever recorded, and its 4.2/5 rating from 6,713 reviews suggests broad satisfaction rather than universal love.

First impressions

The OURA Ring 4 is designed for people who want health tracking without a watch face on the wrist. At Size 8 in Silver, it is compact, wearable all day, and aimed at sleep tracking first, fitness tracking second. That matters because the ring form factor is usually more comfortable overnight than a smartwatch, especially for side sleepers or anyone who finds wrist wear annoying.

The big appeal here is simplicity: no screen, no constant notifications, and a strong focus on sleep patterns, heart rate and activity tracking through the companion app. The listing also highlights up to 8 days of battery life and wireless charging, both of which are genuinely useful for a device meant to be worn continuously.

What does the OURA Ring 4 do well?

The strongest feature is the combination of compact design and detailed health monitoring. Oura’s app integration is the real product, not just the ring itself: the wearable collects data, and the app turns it into sleep and activity analytics. For buyers who care about overnight recovery, consistency and trends rather than step-count vanity metrics, that is the right approach.

Battery life is another major plus. Up to 8 days means you are not charging every night, which is important because sleep tracking only works if you actually keep wearing the device. Wireless charging also reduces friction compared with fiddly proprietary cables on some wearables.

The product’s 72 available variations across colours, sizes and storage options also suggest a mature ecosystem, and the fact that Size 7, Size 8 and Size 9 are all listed at £349.00 shows the pricing is consistent across the core range.

How does it perform against alternatives?

Compared with the Withings ScanWatch Nova at £464.89, the Oura Ring 4 is cheaper by £115.89 and far less bulky for sleep wear. The Withings watch offers ECG, SpO2, temperature monitoring, respiratory health, cycle tracking and a claimed 30-day battery life, so it is the better pick if you want a watch-style device with broader visible functionality. Oura’s advantage is comfort and discretion: for sleep tracking, that can matter more than extra sensors.

Against other Oura sizes at the same £349 price, the decision is less about value and more about fit. The ring only works well if the sizing is right, so the Size Before You Buy approach is important. A poorly fitting ring will undermine comfort and data quality, especially overnight.

Is it good value for money?

At £349, this is not a cheap wearable, and the 4.2-star average shows that some buyers will feel the price is high for something without a display. The value case depends on whether you will use the sleep and recovery insights consistently. If you mainly want basic fitness tracking, there are cheaper options; if you want a comfortable, always-on sleep tracker, the Oura Ring 4 makes more sense.

The good news is that the current price is at the all-time low, with an average price of £349.00 and no premium above that average. That makes this a better buy now than it would be at a higher launch-style price.

What should buyers watch out for?

The main warning is that a ring is not a smartwatch replacement. You do not get a screen, and the product is only as useful as the app insights you actually check. Another limitation is that the listing data does not provide technical detail such as sensor accuracy percentages, so buyers should avoid assuming lab-grade precision from marketing language alone.

There is also a fit risk: unlike a watch, a ring must be sized correctly, and that matters for comfort, battery life and sensor contact. Finally, while 6,713 reviews is a strong sample size, a 4.2/5 score means this is good rather than flawless.

Bottom line

The OURA Ring 4 is best for people who want discreet sleep tracking, all-day comfort and a strong app-led health overview. It is less compelling for buyers who want a full-featured fitness device, a screen, or maximum value per pound.

Is the OURA Ring 4 worth buying in 2026?

Yes, if your priority is sleep tracking and recovery data, because the OURA Ring 4 has a strong 4.2/5 rating from 6,713 reviews and is currently £349.00. That price is also the all-time low, which improves the buying case. It faces credible competition from the Withings ScanWatch Nova at £464.89, but Oura is the better comfort-first option for overnight wear.

How does the ring’s battery life help in real use?

Up to 8 days of battery life makes the OURA Ring 4 easier to wear consistently than many smartwatches that need charging every 1-2 days. That matters because sleep tracking is only useful when the device stays on overnight. Wireless charging also makes topping up simpler.

How does this compare to the Withings ScanWatch Nova?

The OURA Ring 4 is £115.89 cheaper than the Withings ScanWatch Nova, which is listed at £464.89. Withings offers ECG, SpO2, temperature monitoring and a claimed 30-day battery life, so it is the stronger all-round health watch. Oura wins if you want a smaller, less intrusive device focused on sleep and recovery.

What are the main complaints about this product?

The biggest complaints are likely to centre on price, the lack of a screen, and the fact that a ring format is not ideal for everyone. A 4.2/5 rating suggests most buyers are happy, but some will still feel the device is expensive for what it does. Fit and expectation mismatch are the other common issues: people wanting a smartwatch may be disappointed.

Who should avoid it?

Avoid it if you want a budget fitness tracker, a smartwatch with notifications and apps, or a device with broad medical-style features. It is also not the best fit if you dislike wearing rings overnight or if you want maximum hardware value rather than sleep-focused analytics.
