Are you looking for an easy way to track your important health data but don’t want to wear an unsightly wristband? A smart ring is a simple recommendation.
Not only are the smart rings designed to blend in and not draw too much attention to themselves but, according to Oura, the veins in the finger provide light sensors with a pure heartbeat signal that is 100 times stronger than in the wrist. With this in mind, a smart ring is undoubtedly a good choice, but how do you choose between the options?
We compared the recently announced Oura Ring 5 with the Ultrahuman Ring Pro, as both devices promised to provide reliable, accurate and in-depth tracking. While we haven’t reviewed them yet, we’ve checked out their specifications and noted the key differences (and any notable similarities) between the two below.

Price and Availability
At the time of writing, both the Oura Ring 5 and the Ultrahuman Ring Pro are available for pre-order. The Oura Ring 5 will be officially launched on June 4th, while the Ultrahuman Ring Pro will launch later on July 15th.
The Oura Ring 5 comes in a choice of six colours, with the cheapest options being Silver and Black starting at £399. Alternatively you can choose from Stealth, Brushed Silver, Gold and Deep Rose starting at £499.

In comparison, the Ultrahuman Ring Pro comes in a choice of four finishes: Bionic Gold, Raw Titanium, Space Silver and Aster Black – all starting at £429.
The Oura Ring 5 is touted as the world’s smallest smart ring
If you’re looking for a light and compact ring, the Oura Ring 5 is an easy recommendation. Weighing in at a paltry 2g and just 2.28mm thick, the Oura Ring 5 is hailed as the “world’s thinnest smart ring” – and it’s 40% smaller than the Oura Ring 4 too.
Since we haven’t reviewed the Oura Ring 5 yet, we can’t confirm how it actually feels in use. However, considering that we found the larger Oura Ring 4 to sit comfortably on the finger and felt light as well, we expect the Oura Ring 5 to be even more comfortable.
However, that doesn’t mean the Ultrahuman Ring Pro is too big. In fact, it starts at just 2.65mm thick.
Oura Ring 5 requires a monthly subscription to view data
Unlike other fitness trackers, the Oura Ring 5 requires users to sign up for a subscription to really benefit from the tracking data. At £5.99/$5.99 per month, it’s one of the cheaper subscriptions, but there’s still another cost to factor in.
Oura membership allows you to see your health and fitness metrics, which are promised to be more accurate than ever thanks to new signal structures and more powerful LEDs. This means you should expect consistent readings and more accurate job detection than ever before.
In addition, Oura Ring 5 can reveal how well you sleep and give you a corresponding Sleep Score, alongside Readiness and Activity Scores. There is also heart rate monitoring, blood oxygen sensing, stress levels and the ability to set personal activity goals.
In comparison, Ultrahuman Ring Pro does not require additional registration to access many of its tracking features. This means you can access sleep and recovery data, activity results and more without the need to pay any additional fees.
However, you can bundle third-party subscriptions with Ring Pro which may charge you an additional fee. Not only that, but there are also Ultrahuman PowerPlugs which are additional applications that you can pick and choose from, depending on your health and lifestyle. For example, you can track the results of taking GLP-1s, use migraine management tools and track your vitamin D. Some PowerPluses are completely free, while others are an additional fee for the app.
The Ultrahuman Ring Pro also includes a Pro charging case
The Ultrahuman Ring Pro will ship with a Pro Charging Case that not only offers wireless charging, but also stores ringing data for up to one year. In addition, the charging case is designed to preserve the long-term performance of the Ring Pro battery, as it uses an energy-saving method that generates less heat than conventional wireless charging.
A case can also be easily located through Find My Case in the Ultrahuman app, where you can get quick updates, diagnostics and troubleshooting as well.
Otherwise, the Oura Ring 5 comes with a size-specific charger powered by a USB-C connection. Although it also supports wireless charging, you’ll need to buy a compatible charger separately and that’ll set you back £99.
Ultrahuman Ring Pro supports the world’s first biointelligence AI
The Ring Pro is equipped with what Ultrahuman describes as “the world’s first real-time biointelligence AI”. Coined Jade, the AI connects ring data and tags from across the Ultrahuman ecosystem to generate “unprecedented insights”. Ultrahuman explains that unlike conventional LLMs, Jade is able to pull “tangible real-time data” such as or trigger Afib detection.
Ultrahuman also says that, in the future, Jade will be able to order food, change the temperature of your room and flag health issues before they happen – acting as an “independent health agent”. We’re interested to see how this ends up working overtime, but we’ll have to wait and see.
The Ultrahuman Ring Pro promises up to 15 days of battery life
Ultrahuman says the Ring Pro will see up to 15 days of battery life. That’s not even including the Pro charging case that lasts up to 45 days to charge while on the go.
That’s not to say the Oura Ring 5 is a slouch by any means. Sure, it’s shy of the Ultrahuman Ring Pro’s 15-day promise, but Oura’s week-long claim is still a solid effort. It’s just a shame that the Oura Ring 5 doesn’t come with a convenient wireless charger.
Preliminary Decision
Since we are yet to review the Oura Ring 5 and the Ultrahuman Ring Pro, we will refrain from giving a definitive verdict. However, as the “world’s smallest smart ring”, with an easy-to-use app and promising to be the most accurate Oura ever, the Ring 5 is undoubtedly an exciting prospect. Having said that, it is not cheap to buy outright and you will need to balance the monthly costs.
In comparison, the Ultrahuman Ring Pro doesn’t require a monthly subscription fee, and still promises to deliver accurate tracking with a lightweight design. We also appreciate the inclusion of PowerPlugs, which allow you to track specific metrics depending on what’s really important to you.
