Best Smart Ring 2025: Top rings for tracking your health and fitness

Pros

Cons

One of the very first companies to show the world what a smart ring could be, Oura has an outstanding reputation for making some of the best smart rings we’ve ever tested, and the Oura Ring 4 continues that trend brilliantly.

The main reason why Oura’s rings are a step above the competition is that the data collected is accurate and presented in a way that’s easy to understand for both newcomers and seasoned fitness enthusiasts alike. At a glance, the accompanying Oura app can show you any changes to your key health metrics that might signal underlying issues, as well as long-term trends indicating whether you are meeting or missing your fitness goals.

While workout tracking is solid here, the real star of the show is the Oura Ring 4’s sleep tracking. Just like the Whoop MG, the Oura Ring goes all in on rest and recovery, with detailed information about your sleep stages so that you can find out right away if your body is struggling to settle into REM sleep, or the deeper stages of the circadian rhythm, which can point you in the right direction of where (and how) you need to improve.

Also like the Whoop Strap, the Oura Ring 4 requires both an initial upfront payment (starting at £349/$349) and a monthly subscription cost of £4.99/$5.99. This will more than likely put it out of the budgets of most consumers, but given the amount of insight the ring provides into your overall wellbeing, we’d argue that it’s worth the expense for anyone who’s serious about trying to outdo their personal bests and set some records.

Although it might be hard to tell at first glance, the design has been slightly overhauled to make it much more comfortable to wear. The Ring 4 is lighter than its predecessor, so you’ll barely notice its presence when in use, and the material of the interior has changed from resin to titanium, which just feels much nicer against your skin.

Pros

Cons

Ultrahuman has emerged in the last few years to stake its claim in the smart ring market, taking more established brands like Oura to task. What’s impressive is that, in spite of its relative ‘newcomer’ status, Ultrahuman has managed to hit the ground running with its Ultrahuman Ring Air, which really impressed our team of experts.

In terms of the design, Ultrahuman absolutely understood the assignment here. With its very minimalist look, the Ring Air could easily be mistaken for a traditional piece of jewellery until further inspection, which is exactly why smart rings are so appealing compared to smartwatches in the first place. There are quite a few colour options available, including Raw Titanium, Matte Grey and the more recent Brushed Rose Gold edition.

Of course, the Ring Air wouldn’t have made it to this list if it had only stuck the landing where the design was concerned. When it comes to fitness tracking, there’s a lot to love here. The ring can discreetly track your effort throughout the day, using its sensors to monitor your heart rate levels, blood oxygen and more, so that, much like the Whoop MG, you can better understand how much rest you need to get in to accommodate your routine.

Speaking of rest, the sleep tracking on the Ultrahuman Ring Air is also excellent. You can clearly see how much time your body is spending in the different sleep zones, which gives you an idea of what you can do throughout the day to try to accommodate a better night’s sleep. The sleep index score is great in this regard, providing a quick understanding of whether your body is fully rested and ready for a challenging workout.

The accompanying Ultrahuman app is well built, with a modern aesthetic that makes the process of monitoring your health feel a bit more exciting. In what is sure to please more budget-conscious buyers, the Ring Air has no subscription fees whatsoever, so you’ll only have to part with the initial £329/$349 asking price for the pleasure of using it.

Pros

Cons

As much as we love the Oura Ring 4, its subscription model can make it a bit too costly over time. To that end, the RingConn Gen 2 is the ideal alternative, offering much of the same features as Oura, but for just £349/$359 and with no subscription in sight.

Even though RingConn is a lesser-known entity in this market than Oura, the Gen 2 smart ring is still an excellent option for general workout and sleep tracking. It can pick up on all of the key metrics that you’d want to know about, including SpO2 level, your heart rate variability (which signals how well rested you are) and your stress levels. It’s all fairly comprehensive and well laid out in the accompanying app.

What really separates the RingConn Gen 2 from the Oura Ring and all other competitors on the market is that it absolutely reigns supreme when it comes to battery life. Given how small smart rings are, most of them tend to suffer from lacklustre longevity, but this pick can run for up to 12 days on a single charge. That’s more than most smartwatches, and it means you won’t have to worry quite so often about crucial data being missed.

Circling back to sleep tracking, another ace up the Gen 2’s sleeve is the addition of sleep apnea detection. Given just how damaging sleep apnea can be in reducing your chance of having a solid night’s sleep, it’s no wonder that plenty of wearables have started to accommodate for it in their tracking, and it’s great to see RingConn do the same.

As you may have already noticed, RingConn’s wearable is also a stylish bit of kit. You can buy the ring in four unique colours, with a total of nine size options available for each. This makes it easy to find the right combination that’s both comfortable for daily use and fashionable enough to complement your wardrobe.

Pros

Cons

The standard RingConn Gen 2 is already a bit of a bargain compared to the Oura Ring 4, but if the £349/$359 asking price was still just a bit too far out of your remit, then you’ll be glad to know that the company has a more affordable alternative in the RingConn Gen 2 Air. Despite its more affordable £239/$199 price tag, the Gen 2 Air still packs all of the key features that you’d want from a smart ring.

When it comes to the core fitness and sleep tracking experience, there’s very little that differentiates the Gen 2 Air from the full-fat Gen 2. For instance, these smart rings share the same sensors, which means that on the Gen 2 Air, you’re still getting access to your heart rate, blood oxygen levels, stress and more.

The only major feature that’s missing from the Gen 2 Air is sleep apnea tracking. While we won’t deny that it’s a useful feature to have, it’s far from being essential if you’re someone who has either already gone through the necessary steps to determine whether you have sleep apnea, or doesn’t have any major issues with getting to sleep, which would otherwise indicate that you don’t have sleep apnea.

Given that this is a more budget pick within RingConn’s range, we would have understood if the materials for the Gen 2 Air needed to be scaled back quite a bit to help reduce the price, but that isn’t the case here. Instead of a titanium build, the Gen 2 Air uses stainless steel, a significant improvement over plastic, which is more commonly associated with fitness wearables.

You needn’t worry about durability either, as the watch can survive being submerged in depths of up to 10ATM, which means that it’s more than ready for a dip at the local pool.

RingConn hasn’t skimped on its greatest offering of battery life either. The Gen 2 Air can run for a total of up to 10 days on a single charge, which runs rings about the five-day longevity of the Oura Ring 4.

Pros

Cons

Although Samsung was far from the first company to dive into the smart ring market, the Galaxy Ring has shown that it’s still a force to be reckoned with, offering up a genuine alternative to more established picks from the likes of Oura and Ultrahuman.

As much as we love those other smart rings, the Samsung Galaxy Ring is easily the go-to pick for anyone who currently uses one of the best Samsung Galaxy smartphones.

Because this is a Samsung device, the Galaxy Ring is designed with the company’s ecosystem in mind, and if you already use the Samsung Health App as a means of keeping tabs on your fitness levels, then bringing the Ring into the mix is a no-brainer. Even if you already use a Samsung Galaxy Watch, having the ring in tow means that you can leave your watch at home on occasion when you want to travel light (or would just prefer not to wear a watch to bed).

In fact, we’d argue that weaning the Galaxy Ring overnight is a smart idea given just how great its sleep tracking actually is. Far too often, we see sleep data collected and then simply regurgitated as a series of numbers and charts that don’t really mean all that much to most people – Samsung’s Ring, on the other hand, goes down a more practical route by offering tangible advice.

The sleep coaching will offer actionable ways to improve the quality of your rest, and you’ll also be assigned a sleep animal, which is a fun way to better understand your nighttime habits. The data is also funnelled into an Energy Score so you can know right away whether or not your body is ready to take on a more challenging day.

Because the Samsung Galaxy Ring doesn’t work with iPhones, Apple users will need to check out the other options on this list if they are set on buying a smart ring. For Android users, it’s a great option, especially since it doesn’t require a subscription like the Oura Ring 4, and the ring itself is often available at a discount. The catch is that some features require a Samsung phone to work.

Pros

Cons

Anyone who’s been reading our coverage of fitness trackers for some time will no doubt be familiar with the brand Amazit. The company has already released many great yet affordable smartwatches, including the Amazfit Active 2. Now, with the Amazfit Helio Ring, it has finally entered the world of smart rings, offering a more budget-friendly alternative to the competition.

With an original launch price of £269/$199, the Helio Ring was already cheaper than most other smart rings, but in the time since it came to market, the device has seen several price cuts making it easy to find at around the £110/$150 mark. When compared to the mounting costs of the Oura Ring 4, which features both an upfront cost and a monthly subscription, Amazfit’s Helio Ring packs astonishing value.

In spite of its affordable price tag, the Helio Ring still packs a punch where it counts. The optical sensor is capable of tracking your heart rate and sleep cycle, while the EDA sensor can keep tabs on your emotions and stress levels (always handy if you find yourself getting overwhelmed at work and need some guidance).

The ring can also track your skin temperature, which is crucial for women’s health and keeping tabs on the menstrual cycle. Again, for a budget upfront cost, it’s incredible what Amazfit can provide here, and it’s hard to imagine that any adopters of the Helio Ring will feel shortchanged on the value.

All of the health data that’s collected can be easily read in the accompanying Amazfit app, and it’ll tell you right away if any of your baseline metrics are off course, which could signal a broader issue at play. The only reason why you might opt for the RingConn Gen 2 Air instead is that it provides a longer battery life than the up to four-day stint offered by Amazfit.

Still, given just how much money you’re saving at the checkout, having to charge the ring a little more often is hardly a major trade-off.
