The Amazfit Helio Ring is the first smart ring from Chinese tech company Amazfit, best known for its budget-friendly fitness trackers, like the Amazfit Active 2 and its new open-ear earbuds, the Amazfit Up. Staying true to its brand, the Helio Ring undercuts the competition on price, offering a more affordable alternative to rivals like Oura with no added subscription fee.
The design is sleek and minimalist, with a titanium outer shell, and the ring is very comfortable to wear all day and night – possibly the most comfortable smart ring I've tested. The downside? It comes in just one finish and only three size options at the time of writing, which significantly limits your choice compared to competitors.
Functionally, the Helio Ring is built for sleep and wellness tracking. It offers in-depth sleep insights, heart rate monitoring, and energy tracking. There's no auto-detection for workouts and there are only four workout modes to pick from. But, if one of those is your exercise of choice, you do get comprehensive data after each workout – and heart rate tracking as you exercise is accurate, too.
Having said that, if you're looking for a fully-fledged fitness tracker, this isn't it. Most smart rings out there can't compete with fitness watches in those stakes – but that's never been the point of them. Amazfit does say that the ring would work very well if you pair it with one of its smartwatches, and this will be too much hassle and expense for some, but if you're already in the Amazfit ecosystem, it'll make a lot of sense.
Overall, the Amazfit Helio Ring is a solid choice for sleep tracking and general wellness monitoring. While it lacks some of the refinement of its more premium rivals, especially in terms of battery life and app experience, it's a welcome new option in the smart ring space. It'll especially appeal to those already in the Amazfit ecosystem – or anyone looking for a more affordable yet equally capable alternative to some of the best smart rings on the market.
Launch price of $299.99 / £269 / AU$399
Official price now of $199.99 / £169 / AU$269
No subscription required
The Amazfit Helio Ring originally retailed at $299.99 / £269 / AU$399 in 2024. But now you'll find it for $199.99 / £169 / AU$269 on the Amazfit website and some regions also stock it on Amazon. For example, you'll find it on Amazon in the UK right now for a slightly cheaper £149.
How does that stack up against the competition? The Oura Ring 4 starts at $349 / £349 for some designs and colors, but others cost much more. For example, the rose gold version is $499 / £499. Not only is the latest Oura Ring significantly more expensive than the Helio Ring, you'll also need an Oura Ring Membership to unlock its potential, which is $5.99 / £5.99 a month.
For comparison, the Samsung Galaxy Ring is our top smart ring pick at the moment and that currently costs the most at $399 / £399 / AU$749, but that doesn't need an additional subscription.
When the Amazfit Helio Ring first launched, some features required an additional payment. Fortunately, Amazfit appears to have removed that model, making the device even more appealing. With no subscription fees, it stands out from Oura.
Whether the Amazfit Helio Ring offers good value depends entirely on what you need from a wearable. At a lower price point than the Oura Ring, and with no must-buy subscription, it's a solid choice for those focused on sleep and recovery tracking.
If sleep tracking is your top priority, the Helio Ring offers strong value. However, if you're looking for comprehensive workout tracking, a smartwatch or fitness tracker is likely a better buy. Smart rings, this one included, aren't designed to replace a sports watch, and the Helio Ring's limited workout modes prove that. But for those seeking a sleek, comfortable sleep and wellness tracker at a lower cost than the best in the game, it's a strong contender.
Value score: 4/5
My favorite smart ring in terms of design
Only three sizes
Only one finish (but I love it)
The Amazfit Helio Ring is one of my favorite smart rings in terms of design. It's sleek, lightweight, and comfortable. It has a titanium alloy exterior, giving it a more high-end feel than its price suggests. While the inner side (where the sensors sit) is plastic and comfortable. It's impressively slim at just 2.6mm and light at 3.65g. This is very similar to the Oura Ring, which is 2.88mm thick and weighs from 3.3g to 5.2g depending on the size. In short, there's not much in it, so don't assume affordability means bulkier or heavier.
However, where it does fall short is the Helio Ring comes in only one finish, a brushed silver with tiny dots on the front, which I personally love. The popular matte black options from other brands tend to scratch easily, and gold versions can be too flashy and shiny for me to wear everyday. Of course, this is all down to personal preference, and if you want something that looks different, Oura and Samsung offer more color choices.
Fit-wise, there are just three sizes available (8, 10, and 12), which is far more limited than other smart rings that offer a wider range of sizes. Oura offers 12 different sizes. If one of these fits you, great – but if not, you're out of luck.
Another big plus is durability. Some smart rings I've tested got scuffs within hours, especially those with matte finishes, but the Helio Ring has held up well with only minor scratches after several weeks.
The Amazfit Helio Ring is rated at 10 ATM water resistance, meaning it can handle surface swimming and snorkeling, but not scuba diving. In practical terms, it's safe for most daily water exposure, including showers, workouts, and casual swims.
A small vertical line on the exterior of the ring marks the sensor placement, which should face the inside of your finger for the best tracking. Unlike some other smart rings, Amazfit makes this clear, which is a nice usability touch.
This is one of the best-designed smart rings I've tested. It's slim and lightweight, subtly stylish, and surprisingly scratch-resistant. The limited sizes and finishes might be a drawback for some, but if the fit works for you, it's a great-looking, comfortable option.
Design score: 4 / 5
Excels at sleep and general wellbeing tracking
Limited workout tracking
App is simple but works well
For a more affordable smart ring, the Amazfit Helio Ring packs in plenty of features. Sleep tracking is where this ring shines. You get everything you'd expect, sleep stages, duration, and detailed metrics presented in easy-to-read charts.
But it also monitors breathing, skin temperature, heart rate variability, and resting heart rate while you sleep. All this data is used to generate a morning readiness score, telling you how well you've recovered, how much energy you have, and what kind of activity you're primed for.
There's also an EDA sensor (electrodermal activity), which, combined with heart rate data, aims to track stress and emotional responses throughout the day.
Unlike fitness watches, smart rings aren't designed for workouts, and the Helio Ring is no exception. It only offers four workout modes, which is a bit disappointing. But if you mostly run or walk, you'll still get solid data like workout time, speed, heart rate, VO2 max, calories burned, and GPS-tracked routes.
Amazfit suggests pairing the ring with an Amazfit smartwatch – the idea being that the watch handles workouts, while the ring tracks sleep and recovery. Both sync seamlessly in the Zepp app, making it a well-rounded system if you're in the Amazfit ecosystem.
There are a couple of other features here worth mentioning, like PAI (Personal Activity Intelligence). This is your unique cardiovascular fitness score based on heart rate and daily activity. At first, it felt like just another number, but PAI actually provides a useful gauge of overall fitness. As someone shifting from a weightlifting and yoga focus to more cardio, I found it surprisingly helpful.
You can also track your menstrual cycle from within the Zepp app, which works similarly to period apps like Flo or Clue, predicting cycles and sending reminders. I didn't test this, but it's a solid addition if you want all of your health and fitness data in one place.
With all this data, a good app is crucial. The Zepp app has improved recently and while it's not as sleek as Oura's, it's clean, intuitive, and lets you find key insights quickly. Personally, I prefer a simple interface over something overly designed anyway.
At launch, some features within the app required a Zepp Aura subscription, this is Amazfit's extra sleep and recovery assistant, this included deeper sleep insights, relaxation tracking, and personalized sleep music. But they're now all free to Helio Ring users.
Features score: 4 / 5
Solid at sleep tracking
Really comfortable to wear
Won't replace your fitness tracker
Amazfit claims the Helio Ring lasts up to four days, but in real-world use, I got closer to three-and-a-half days with all health tracking features turned on. That's noticeably less than the six days you'll get from the Oura Ring and the seven days from the Samsung Galaxy Ring. Charging is quick, taking about an hour and a half via a USB-C wireless charging plinth.
In terms of comfort, this is one of the most wearable smart rings I've tested. The lightweight, slim design makes it easy to forget you're even wearing it. The size 8 fit perfectly on my index finger, making it feel seamless throughout the day and night. However, with only three sizes available (8, 10, and 12), finding the right fit might be tricky for some. Hopefully, future versions will offer more size options.
Sleep tracking is where the Helio Ring really stands out. It provides a detailed breakdown of sleep stages alongside heart rate and breathing monitoring. The data syncs quickly to the Zepp app, where you can view trends and graphs over time. Compared to other wearables, the sleep tracking felt mostly accurate, though it occasionally overestimated my sleep by a few minutes. One feature I particularly liked was nap tracking, which tends to be hit-or-miss with other devices, but as long as I napped for more than 20 minutes the Helio Ring picked it up accurately.
One of its standout features is how sleep data influences readiness, exertion, and recovery scores, giving you real insights into how well your body has recovered overnight. You can even toggle off certain metrics, like hypopnea (airway obstruction) detection for sleep apnea risk if they're not relevant to you, which helps conserve battery life.
For me, the recovery tracking was especially useful. Not just physically as I recover from a back injury, but also mentally, after dealing with seasonal depression earlier in the year. If you're in a similar situation – trying to rebuild fitness or improve sleep – this kind of data can be genuinely helpful. On the other hand, if you're already in peak shape, I'm not sure these insights would add much value.
When it comes to workout tracking, there are some limitations. Unlike smartwatches or fitness trackers, it doesn't auto-detect workouts and only supports manual tracking for running, walking, cycling, and treadmill sessions. This was frustrating, as my fitness routine includes a lot of yoga and strength training, neither of which are supported. However, for the workouts it does track, the data is solid. When I took the Helio Ring for a run, I could see everything I needed in the Zepp app, including workout time, average speed, heart rate, VO2 max, calories burned, and GPS-tracked routes.
So while it's not a dedicated fitness tracker, it does a decent job for running and walking. For more complete sports tracking, pairing it with an Amazfit smartwatch is the best way to get a broader picture of both fitness and recovery.
Performance: 4 / 5
You already have a watch in the Amazfit ecosystemThe ideal setup is a smartwatch for fitness and daytime tracking and a smart ring for sleep and recovery at night.
Sleep tracking is your top priorityThe Helio Ring excels at sleep monitoring, using data like heart rate, temperature, and breathing patterns to inform your Readiness and Exertion scores.
You find other wearables uncomfortableThis is one of the most comfortable smart rings I've tested. If you've struggled with wristbands or smartwatches for sleep tracking, this could be the perfect solution.
You're willing to pay more for a premium experienceIf budget isn't a concern, the Oura Ring offers a more refined experience, plus better battery and size and finish options – just expect to pay extra, both upfront and for the subscription.
You need a strong workout tracker If all you need is tracking for walking and running, you do get good data. But for anything beyond that, there are limited workout modes.
The sizes don't work for youThe Helio Ring only comes in three sizes (8, 10, and 12). If your index finger (the most comfortable placement) doesn't match one of these, you'll need to look elsewhere.
Oura Ring 4If you're looking for a more refined experience with a wider range of colors and sizes, as well as a better battery the latest Oura Ring is a great choice. Just be prepared to pay more upfront – and for the ongoing subscription to unlock full featuresRead our full Oura Ring 4 review
Ultrahuman Ring AirPricier than both the Oura and Helio Rings at the time of writing, but it comes without a subscription. If you want more finish and size options with no additional monthly costs and a solid battery, this is a strong alternative.Read our full Ultrahuman Ring Air review
Worn 24/7
Tested for several weeks
Lots of expertise testing smart rings to compare
I tested the Amazfit Helio Ring for three weeks, pairing it with an iPhone 14 Pro. Aside from taking it off for charging and showers (it's waterproof, but I was cautious about soap and shampoo), I wore it 24/7 – through outdoor runs, gym sessions, long workdays in coffee shops, evenings at home, and, of course, while sleeping. It's been put through its paces in a wide range of real-world environments.
As someone who has reviewed numerous wearables over the years, I've tested a variety of smart rings – including models from Ultrahuman, Motiv, Ringconn, Evie, multiple generations of the Oura Ring, and more. The smart ring market is only just breaking into the mainstream, but having worn so many, I have a solid sense of what to expect, how they should feel, and what makes a great user experience.
