So, you’re thinking of buying a smart ring. Well, some good news. Picking the best of the lot is incredibly easy right now. The “bad” news is that, as far as trustworthiness and reliability, your choices are somewhat limited, as this is still a niche and emerging gadget category.
Smart rings are in the middle of a resurgence. That means a lot of experimental ideas and newcomer tech brands you’ve probably never heard of. Enough competitors have cropped up that I spent the better part of last summer rocking six rings like a high-tech mafia don. While these aren’t necessarily bad products (some are pretty good), many aren’t as polished as what you’d see in more mature categories like smartwatches, headphones, and smartphones.
Speaking of which, there are a few things to know about the category. Currently, these devices are primarily health trackers. Their benefit is that they’re more discreet and better suited to sleep tracking than a smartwatch. However, the vast majority don’t include smart alarms or push notifications. This makes them best suited for casual athletes or more wellness-minded people. In most cases, hardcore athletes would be better served by a smartwatch or fitness tracker, with a smart ring serving as a supplementary source of data. (But that’s quite an expensive endeavor.) Smart rings are also ill-suited for weightlifters, as they can easily scratch against equipment.
With that in mind, here’s the best smart ring for most people in 2025 — and a handful of runners-up worth highlighting for the more tech-adventurous.
What I’m looking for
Smart rings are meant to be a stylish and discreet alternative to traditional fitness trackers. That requires a combination of experiential testing and benchmarks. We wear them daily for weeks to see how well they accommodate bloated fingers and temperature changes. We don’t take them off in the shower or to wash dishes to test waterproofing. And we compare them to a smartwatch, the Oura Ring, and a smart bed to gauge sleep and health tracking accuracy. Other factors we consider are size ranges, sizing kits, app design, syncing times, and, of course, battery life.
Your fingers will bloat. How accommodating is the design? What’s the size range offered? (Some of us have tiny fingers!) How easy is it to return?
Many people want a smart ring to double as a piece of jewelry. Is it comfortable to wear 24 / 7? Is the design versatile for all sorts of events? Will you get compliments for wearing it?
Does the finish scuff? Will you see visible scratches if you wear other rings alongside it?
Rings are easy to lose. Does it have a charging case or does it use a charging dock that a cat can easily knock off your nightstand? Sleep tracking is one of the most popular use cases for a smart ring, and for that you need good battery life. How much do you get on a single charge?
Many smart ring companies are newcomers. The hardware can be nice, but it means nothing if the app is a nightmare. How easy is the ring to update and sync? Does it sync with larger platforms like Apple Health or Google Health Connect?
Best smart ring for most people

$342
The Good
- More sizes
- Slimmer design
- Expanded auto workout detection
- Redesigned app
- Better battery life
The Bad
- Subscription required to get all features
- I still wish this had a charging case
Surprising no one, it’s the Oura Ring 4.
I can already hear some of you shouting, “But what about the subscription!” And I agree. Even Oura’s relatively affordable $5.99 monthly fee can feel more like $100 when you consider the sheer number of apps, gadgets, and services asking for a chunk of your monthly paycheck. However, Oura is still the best in terms of hardware, size range, features offered, app, dedication to research, and experience in the field. Many of the smart rings available today follow the example Oura set this past decade.
The upgrades from the Oura Ring Gen 3 to the Oura Ring 4 were mostly software-based, with minor hardware refinements. You can read more in my review, but the gist is a more accurate heart rate and blood oxygen algorithm, improved automatic activity detection, and an expanded range that spans size 4 to 15. The app has been redesigned to be less cluttered, and in the last few months, Oura added AI-powered meal logging and glucose tracking, the latter of which requires Oura users to purchase a Dexcom Stelo CGM ($99). It also recently launched an AI chatbot. (Of the AI chatbots in health trackers I’ve tested, this one is among the more polished implementations — though it often feels like Captain Obvious-level insights.)
I’ve been long-term testing three iterations of the Oura Ring since 2018. Accuracy, design, and comfort have improved with each generation. The company continues to frequently and clearly communicate research and scientific developments. Third-party retail options have expanded, and I’ve seen investment pour into Oura. In an emerging category, these things matter. A lot. While I believe some of Oura’s newer competitors do some things better or have more creative ideas, Oura is the one I continually recommend for its combination of reliability, accuracy, and experience.
Read my full Oura Ring 4 review.
If subscriptions are an absolute dealbreaker, you’ll find zero protest here. In that case, here are the best alternatives to the Oura Ring.


$286
The Good
- Excellent hardware
- Long battery life
- Slim, lightweight design
- No subscription
The Bad
- Android only
- Better if used with Samsung products
- Accuracy is a mixed bag
The $400 Samsung Galaxy Ring nails the hardware. Its charging case is more elegant than the Oura Ring’s, and I prefer the slightly concave design for comfort. It also has the second widest size range. If you’re already all-in on a Samsung Galaxy Watch 7 or Ultra, you get the added benefit of extended battery life. If you have the latest Galaxy Z Flip 6 or Z Fold 6, Samsung also has gesture controls for the ring so you can control the camera.
There are a lot of interesting ecosystem-centric ideas that Samsung has for its Galaxy Ring, but while there’s no subscription (yet), it’ll cost you a pretty penny to unlock the ring’s full potential. Without discounts, we’re talking about $1,800 to nearly $3,000 for the phone, watch, and ring. The Galaxy Ring is also a first-gen device with some first-gen quirks, too. Samsung is still catching up with sleep tracking accuracy, and its Galaxy AI-powered health features are rather hit or miss.


$299
The Ultrahuman Ring Air is a subscription-free alternative to the Oura Ring that offers a more fitness-focused experience.
I’m also keen on the $350 Ultrahuman Ring Air. It gave the Oura Ring an honest run for its money when I tested six smart rings at once last year. It’s not quite as good with accuracy, but it’s on par with comfort and design. The app has much more of a fitness focus than wellness. Instead of a subscription, it has “PowerPlugs.” You can think of them as add-on features. Some are free, like smart alarms and cycle tracking. Others will come with an additional fee, like a planned atrial fibrillation detection PowerPlug and a cardio adaptability metric, which currently costs $2.90 a month.


$199
A lighter, entry-level version of RingConn’s latest smart ring. It offers roughly 10 days of battery life, AI features, and basic health and sleep tracking.
Lastly, I’ve been testing the RingConn Gen 2 Air, a slimmer, entry-level version of its Gen 2 ring. At $200, it’s the most affordable smart ring I’ve tested but looks and feels a lot nicer than the original RingConn I tested last summer. I had issues with the RingConn’s squarish shape, but it’s much less noticeable this time around and more comfortable. It’s broadly accurate, and the app goes heavy on AI, to middling effect. It has great battery life. I’ve gotten around eight to nine days on a single charge — far better than any other smart ring I’ve tested.
Update, July 21st: Updated to reflect current pricing and availability.

![‘Witch Hat Atelier’ Creator, Coco Star on How the Anime Exceeded Expectations
As far as contemporary anime is concerned, the “big three” fantasy series have finally been christened, thanks to the wondrous arrival of the last in its holy trinity on Crunchyroll: Bug Films’ absolutely magical adaptation of Kamome Shirahama‘s beloved manga, Witch Hat Atelier. At Anime Expo 2026, io9 got to speak with Shirahama and Coco’s Japanese voice actor, Rena Motomura, about how Bug Films utilized its production delay to deliver an adaptation that honored, and occasionally outshone, the artistry of its source material, what keeps the anime community’s newly adopted daughter so optimistic in an insane world, and whether Pointed Cap witches or Brimmed Caps have the best sense of fashion. Kamome Shirahama’s Brushbuddy. © Isaiah Colbert/io9 Isaiah Colbert, io9: During the anime’s delay, Bug Films announced that certain scenes needed additional time and attention, hoping the anime would be as big as The Lord of the Rings for anime fans. What scenes from this season exceeded your expectations?
Rena Motomura: There are so many scenes that exceeded my expectations. But in episode one, at the end, when Coco’s screaming, “Mom,” and then Qifrey takes her up into the sky as the magic is being triggered, they’re skyward and having that moment together—I saw a bit of it in the teaser—but when I saw it in the anime episode, it made me so emotional. I saw exactly how my sensei’s world was being brought to life in anime form, and how the frames were coming together to tell this story. That’s when I knew with great conviction that we were going to have something really special on our hands.
[embed]https://www.youtube.com/watch?v=ZSGVFk9w5qA[/embed] Kamome Shirahama: This was really talked about a lot, but episode five, for me personally, when I saw it, I was super wowed. It made me really feel like I was watching a film in the theater. [embed]https://www.youtube.com/watch?v=E9URbx38AIY[/embed] io9: Shirahama‑sensei, your live‑tweeting during the broadcast has delighted fans—especially when you pose questions about characters as if you didn’t write them. Which aspects of the anime were your favorites to see realized on screen—and for Motomura‑san, which scenes were the most memorable or rewarding for you to record as Coco?
Shirahama: Yeah, for sure. There’s things that you can see in the anime that the manga doesn’t contain—certain elements that make the world more expansive, more brilliant, more rich, and colored. Those are the things I was looking forward to the most. Motomura: For me, it’s the last scene in the dragon maze when Coco has this realization that her actions have put everyone into danger and she’s tearing up, saying, “I’m really sorry that this happened.” Up until that point, she’s been really cheerful. Really sort of outgoing. But then you realize that deep inside her heart, she’s been carrying a lot of this anxiety and worry that’s just piling up. As I was playing the character through the scene, it reminded me of how, through episodes one to three, there must have been a lot of internal thoughts—a lot of anxiety and worry. And that part I empathize with. I started tearing up doing the scene. And even when I look back on it now, I start tearing up. io9: For many, Coco embodies hope and determination, even when the world around her feels overwhelming or insane. How does each of you interpret the way her character maintains that sense of glowing optimism, and what does she represent to you within the story?
Shirahama: Coco’s greatest motivation is her love for magic. Even when she faces situations that are fearful or scary, she knows that’s not all there is to magic. And she knows that there’s hope. And she holds on to that hope as her core belief. And that’s what moves her forward. Motomura: Coco has this enormous admiration for magic. I think as long as she holds on to that admiration, she’ll be able to keep moving forward. In the story, I believe her existence is like the mast of a ship. She is a very certain presence in the story, and deep inside her heart—at her core—she holds on to this admiration for magic that’s going to carry everything forward.
[embed]https://www.youtube.com/watch?v=jA1sPU4F1n4[/embed] io9: This season introduced a variety of intricate, hand-drawn spells. Of the spells featured so far, which one stands out as your personal favorite, and why? Motomura: For me, it’s the very first spell that Coco came up with for herself—the straight arrow that carries her up into the sky in her time of need as she’s flying upwards. I really felt like this spell was an embodiment of her personality. In this moment, she has nothing. She has no skills, no knowledge, nothing. But she has to do something. So she comes up with this spell to help her get out of a tough situation. The name, too, is super cute. I believe Shirahama-sensei named it 空すっ飛び (sorasuttobi/Skysoaring Seal) in Japanese. Shirahama: For me, it’s the spell that Qifrey casts in episode six when they’re trying to have a picnic in the rain, so he creates this bubble where the rain can’t touch them. I’m so jealous because we get a lot of rain in Japan, and I feel like that would be a great spell to have when you have to walk your dog in the rain.
[embed]https://www.youtube.com/watch?v=Yu0qoRHqDt8[/embed] io9: If you had to choose—based on fashion alone, no morals at play—would you see yourselves more as the Pointed Cap witches in Witch Hat Atelier or one of the Brimmed Caps? Motomura: Oh! That’s a very difficult question. But personally, I have a bit of an ambition for the Brimmed Caps because ever since I was a child, I thought those kinds of hats were very cool. And then when I came into the world of Witch Hat Atelier, the fact that they cover their face so they can practice forbidden magic, I was like, “Oh, that is so cool.” I know that, morally speaking, as Coco, it’s a questionable answer. But I really like the Brimmed Caps…just as fashion! Shirahama: (Laughs) I feel like the Brimmed Caps might be more popular in a place like California, where you guys get so much sun. For me, personally, I really like the silhouette of the Pointed Caps, so I prefer those.
Witch Hat Atelier is streaming on Crunchyroll, and season two is in production. io9 is on the ground at Anime Expo 2026. We’ll be bringing you updates on all the biggest panels, screenings, and announcements, plus exclusive one-on-one interviews with the people behind some of the best and most popular anime around.
