It is official. After months of leaks, Oura just launched the Ring 5, and it is a genuine watershed moment for the smart ring. The new ring is 40 percent smaller than the last one, it added blood pressure signals, the battery lasts longer, and the sensors are the most accurate Oura has ever shipped. It also costs more. If you have been curious about putting a tiny health tracker on your finger, or you own an older Oura and are wondering whether to upgrade, this is the breakdown you need. Here is what the Oura Ring 5 is actually like and whether it is worth it.

The single biggest change with the Ring 5 is how small it is. Oura unveiled the fifth generation of its popular smart ring on Thursday, starting at $399. The Ring 5, which Oura describes as the world's smallest smart ring, arrives just a year and a half after the company launched the Ring 4. The Ring 5 is 40% smaller than its predecessor. youtube

The numbers are genuinely impressive. It's 6.09mm wide and 2.28mm thick, and it weighs from just 2g if you pick one of the smaller sizes. Even the largest Ring 5 only tips the scales at 2.69g. For context, that is lighter than a single sheet of paper folded a few times. The complaint about every previous Oura ring has been that it feels chunky on your finger. The Ring 5 effectively eliminates that complaint. Tech Startups

Crucially, Oura did not just shrink the old ring. "We didn't just shrink Oura Ring 4; we re-engineered it from the ground up." This is made possible in part by new low-profile sensor domes and a brand-new battery design. It means the frame could be made smaller overall, and as a bonus, Oura says it's more durable than its predecessor. The ring is built to take a beating too. The Ring 5 has a non-allergenic titanium interior and exterior with a new, extra-strong physical vapor deposition coating which enhances scratch resistance. It's also rated for 100m water resistance. fintechfutures + 2

The whole point of an Oura ring is accuracy. It tracks your sleep, heart rate, body temperature, and recovery, and those readings are only useful if they are precise. The Ring 5 made meaningful improvements here. Oura Ring 5 features precision-engineered, low-profile sensor domes for better skin contact and clearer, more consistent readings, while 12 signal pathways deliver greater accuracy across more finger types and skin tones. fintechfutures

The "more finger types and skin tones" detail matters more than it sounds. Optical sensors that read your pulse through light have historically been less accurate on darker skin tones and on certain finger shapes. Oura says it has reengineered its sensors for better skin contact and added more powerful LEDs in an effort to increase accuracy across a wider range of finger sizes and skin tones. Making the technology work well for more people is a genuine improvement, not just a marketing line. youtube

Battery life also got better, which has always been one of the Oura ring's strongest features compared to smartwatches that need daily charging. The Ring 5 can last between six to nine days, compared to the five to eight days on the Ring 4. This chemical and mechanical redesign improved the efficiency, durability and longevity of the battery, and comes with specialized firmware to optimize for battery. youtubefintechfutures

There is also a new charging accessory worth knowing about. With the Oura Ring 5 Charging Case (sold separately), you can stay powered up for up to one month of battery and wireless charging on-the-go. The matchbox-sized case is made of the highest grade recycled aluminum and easily fits into your pocket, carry-on, or gym bag. Think AirPods case, but for your ring. It is the kind of thing that sounds unnecessary until you are traveling and never have to think about charging. fintechfutures

This is the most important addition, and the one with the biggest long-term implications. The Ring 5 is launching alongside new software updates that include blood pressure signals, live activity tracking, on-demand care, and other features that will also roll out to the Oura Ring Gen3 and later. youtube

Blood pressure tracking from a ring is something the entire wearable industry has been racing toward. High blood pressure affects more than a billion people and is the leading risk factor for heart disease, but most people who have it do not know, because it has no symptoms and you only catch it if you happen to measure. A ring that quietly monitors blood pressure signals while you sleep and during the day could catch hidden hypertension that would otherwise go undetected for years. Oura has been building toward this for a while. Oura launched a Blood Pressure Profile study to explore how its smart ring could help detect hidden hypertension risks. StorageReview

The software story is bigger than any single feature, though. Oura Ring 5 connects your daily health signals with longer-term insights. Our latest generation also launches alongside new Oura software that moves from daily health tracking to providing members with a more comprehensive, predictive view of their health. The shift from "here is what happened last night" to "here is what is likely coming and what you should do about it" is the direction the whole product is heading. The ring is becoming less of a fitness gadget and more of an early-warning health system. fintechfutures

One important note: the software features are not exclusive to the Ring 5. The features will also roll out to the Oura Ring Gen3 and later. So if you own a Ring 3 or Ring 4, you will get blood pressure signals and the new software too, which softens the case for upgrading purely for features. youtube

Here is the money breakdown. The Oura Ring 5 starts at £399/$399/€429 for the cheapest model, but this is just if you're happy with the Silver or Black finishes. That is a $50 increase over the Ring 4's $349 starting price. You also still pay for the Oura membership, which runs $5.99 per month, to access the full feature set. And the charging case is sold separately. So the real first-year cost is closer to $470 plus the case. Tech Startups

There are six finishes to choose from. It comes in six finishes, including a redesigned Gold with a truer gold tone, an updated Deep Rose with a copper-like look, plus Silver, Brushed Silver, Black, and Stealth. It's available in sizes 6 to 13. The new smart ring is available for preorder starting today and will start shipping on June 4. youtube + 2

So who should buy it? If you own a Ring 4, the upgrade case is weak. The new software features are coming to your existing ring anyway, so unless the smaller size genuinely matters to you, skip it. If you own a Ring 3 or older, this is a more meaningful jump in comfort, accuracy, and battery, and a reasonable time to upgrade. And if you have never owned an Oura and have been waiting for the right moment, the Ring 5 is the best version yet, and the dramatically smaller size removes the main reason people found the older rings annoying to wear all day.

The honest summary: the Ring 5 is the most significant smart ring upgrade Oura has ever shipped, mostly because of the size reduction and the blood pressure signals. It is more expensive, and the subscription requirement remains a real ongoing cost. But for a device you wear 24 hours a day that quietly tracks your health and may one day catch a serious problem before you would have noticed it yourself, a lot of people will find it worth the price. The smart ring just grew up, and the Ring 5 is the clearest proof yet.

We will keep tracking the smart ring space and bring you the next chapter as it lands. Stay healthy out there.
