Looking for an easy way to track your key health data but don’t want to wear an unsightly wrist strap? A smart ring is an easy recommendation.
Not only are smart rings designed to blend in and not draw too much attention to themselves but, according to Oura, arteries in the finger give optical sensors a cleaner pulse signal that is up to 100 times stronger than at the wrist. With this in mind a smart ring is undoubtedly a great choice, but how do you choose between the options?
We’ve compared the recently announced Oura Ring 5 to the Ultrahuman Ring Pro, as both devices are promised to offer reliable, accurate and in-depth tracking. While we haven’t reviewed either yet, we’ve assessed their specs and noted the key differences (alongside any noteworthy similarities) between the two below.
Otherwise, make sure you visit our round up of the best smart rings and best fitness trackers, while our Oura Ring 5 vs Ring 4 and Oura Ring 5 vs Ring 3 guides explain what’s new with the latest generation.
Price and Availability
At the time of writing, both the Oura Ring 5 and Ultrahuman Ring Pro are currently available to pre-order. The Oura Ring 5 will officially launch on June 4th, whereas the Ultrahuman Ring Pro will launch a bit later on July 15th.
The Oura Ring 5 comes in a choice between six colours, with the cheapest options being Silver and Black which start at £399. Alternatively you can opt for Stealth, Brushed Silver, Gold and Deep Rose which starts 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 of which start at £429.
Oura Ring 5 is hailed as the world’s smallest smart ring
If you want the lightest and thinnest possible ring, then the Oura Ring 5 is an easy recommendation. Weighing from a teeny 2g and at just 2.28mm thick, the Oura Ring 5 is hailed as being the “world’s smallest smart ring” – and it’s 40% smaller than the Oura Ring 4 too.
As we haven’t reviewed the Oura Ring 5 yet, we can’t verify how it really feels in use. However, considering we found the larger Oura Ring 4 sat well on the finger and felt light too, we expect the Oura Ring 5 to be even more comfortable.
However, that’s not to say the Ultrahuman Ring Pro is particularly hefty. In fact, it starts with a thickness of just 2.65mm.
Oura Ring 5 requires a monthly subscription to see data
Unlike other fitness trackers, the Oura Ring 5 requires users to sign up to a subscription to really benefit from the data tracking. At £5.99/$5.99 a month, it’s one of the cheaper subscriptions, but it is still another cost to factor in.
An Oura membership allows you to actually see your health and fitness metrics, which are promised to be more accurate than ever before thanks to new signal architecture and more powerful LEDs. This means you should expect more consistent readings and more accurate activity detection than its predecessors.
In addition, the Oura Ring 5 can reveal how well you slept and provide you with a relevant Sleep Score, alongside Readiness and Activity Scores. There’s also heart rate monitoring, blood oxygen sensing, stress levels and the ability to set personalised activity goals too.
In comparison, the Ultrahuman Ring Pro does not require an additional subscription to access its plethora of tracking features. This means you can access sleep and recovery data, activity results and more without needing to pay any extra fees.
However, you can pair third-party subscriptions with the Ring Pro which may charge you an additional fee. Not only that, but there are also Ultrahuman PowerPlugs which are add-on apps that you can pick and choose from, depending on your health and lifestyle. For example, you can track the effects of taking GLP-1s, use migraine management tools and even track your vitamin D too. Some PowerPlus are completely free, while others are an additional fee via the app.
Ultrahuman Ring Pro includes the Pro Charging Case
The Ultrahuman Ring Pro will be shipped with the Pro Charging Case which not only provides convenient wireless charging, but also stores up to one year of ring data too. In addition, the charging case is designed to preserve the long-term performance of the Ring Pro’s battery, as it uses an energy-efficient mechanism that generates less heat than conventional wireless charging.
The case can also be easily located via Find My Case in the Ultrahuman app, where you can also receive faster updates, diagnostics and troubleshooting too.
Otherwise, the Oura Ring 5 comes with a size-specific charger that’s powered via USB-C connection. While it does also support wireless charging, you will 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 fitted with what Ultrahuman describes as the “world’s first real-time biointelligence AI”. Coined Jade, the AI connects ring data with markers from across the Ultrahuman ecosystem to produce “unprecedented insights”. Ultrahuman explains that unlike normal LLMs, Jade is able to pull “real-time actionable insights” such as or triggering Afib detection.
Ultrahuman also claims that, in the future, Jade will be able to order food, change your room temperature and flag health issues before they even occur – acting as an “autonomous health agent”. We’re intrigued to see how this really ends up working overtime, but we’ll have to wait and see.
Ultrahuman Ring Pro promises up to 15 days of battery life
Ultrahuman claims that the Ring Pro will see up to a whopping 15 days of battery life. That’s not even factoring in the Pro Charging Case which stores up to a whopping 45 days for topping up while you’re on the move.
That’s not to say the Oura Ring 5 is a slouch by any means. Sure, it’s a bit shy of the Ultrahuman Ring Pro’s promise of 15 days, but Oura’s claim of up to a week is still a solid effort. It’s just a shame the Oura Ring 5 doesn’t come equipped with a more convenient wireless charger.
Early Verdict
As we’re yet to review the Oura Ring 5 and Ultrahuman Ring Pro, we’ll refrain from giving a conclusive verdict. However, as it’s the “world’s smallest smart ring”, has an easy-to-use app and promises to be the most accurate Oura ever, the Ring 5 is undoubtedly an exciting prospect. Having said that, it’s not cheap to purchase outright and you will need to factor in the monthly cost.
In comparison, the Ultrahuman Ring Pro doesn’t need a monthly subscription fee, and still promises to deliver accurate tracking in 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.
