The best smart rings for tracking sleep and health

Published

on

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.

Ronnie Sheth, CEO, SENEN Group: Why now is the time for enterprise AI to ‘get practical'

Published

on

Before you set sail on your AI journey, always check the state of your data – because if there is one thing likely to sink your ship, it is data quality.

Gartner estimates that poor data quality costs organisations an average of $12.9 million each year in wasted resources and lost opportunities. That’s the bad news. The good news is that organisations are increasingly understanding the importance of their data quality – and less likely to fall into this trap.

That’s the view of Ronnie Sheth, CEO of AI strategy, execution and governance firm SENEN Group. The company focuses on data and AI advisory, operationalisation and literacy, and Sheth notes she has been in the data and AI space ‘ever since [she] was a corporate baby’, so there is plenty of real-world experience behind the viewpoint. There is also plenty of success; Sheth notes that her company has a 99.99% client repeat rate.

“If I were to be very practical, the one thing I’ve noticed is companies jump into adopting AI before they’re ready,” says Sheth. Companies, she notes, will have an executive direction insisting they adopt AI, but without a blueprint or roadmap to accompany it. The result may be impressive user numbers, but with no measurable outcome to back anything up.

Even as recently as 2024, Sheth saw many organisations struggling because their data was ‘nowhere where it needed to be.’ “Not even close,” she adds. Now, the conversation has turned more practical and strategic. Companies are realising this, and coming to SENEN Group initially to get help with their data, rather than wanting to adopt AI immediately.

“When companies like that come to us, the first course of order is really fixing their data,” says Sheth. “The next course of order is getting to their AI model. They are building a strong foundation for any AI initiative that comes after that.

“Once they fix their data, they can build as many AI models as they want, and they can have as many AI solutions as they want, and they will get accurate outputs because now they have a strong foundation,” Sheth adds.

With breadth and depth in expertise, SENEN Group allows organisations to right their course. Sheth notes the example of one customer who came to them wanting a data governance initiative. Ultimately, it was the data strategy which was needed – the why and how, the outcomes of what they were trying to do with their data – before adding in governance and providing a roadmap for an operating model. “They’ve moved from raw data to descriptive analytics, moving into predictive analytics, and now we’re actually setting up an AI strategy for them,” says Sheth.

It is this attitude and requirement for practical initiatives which will be the cornerstone of Sheth’s discussion at AI & Big Data Expo Global in London this week. “Now would be the time to get practical with AI, especially enterprise AI adoption, and not think about ‘look, we’re going to innovate, we’re going to do pilots, we’re going to experiment,’” says Sheth. “Now is not the time to do that. Now is the time to get practical, to get AI to value. This is the year to do that in the enterprise.”

Apptio: Why scaling intelligent automation requires financial rigour

Published

on

Greg Holmes, Field CTO for EMEA at Apptio, an IBM company, argues that successfully scaling intelligent automation requires financial rigour.

The “build it and they will come” model of technology adoption often leaves a hole in the budget when applied to automation. Executives frequently find that successful pilot programmes do not translate into sustainable enterprise-wide deployments because initial financial modelling ignored the realities of production scaling.

“When we integrate FinOps capabilities with automation, we’re looking at a change from being very reactive on cost management to being very proactive around value engineering,” says Holmes.

This shifts the assessment criteria for technical leaders. Rather than waiting “months or years to assess whether things are getting value,” engineering teams can track resource consumption – such as cost per transaction or API call – “straight from the beginning.”

The unit economics of scaling intelligent automation

Innovation projects face a high mortality rate. Holmes notes that around 80 percent of new innovation projects fail, often because financial opacity during the pilot phase masks future liabilities.

“If a pilot demonstrates that automating a process saves, say, 100 hours a month, leadership thinks that’s really successful,” says Holmes. “But what it fails to track is that the pilot sometimes is running on over-provisioned infrastructure, so it looks like it performs really well. But you wouldn’t over-provision to that degree during a real production rollout.”

Moving that workload to production changes the calculus. The requirements for compute, storage, and data transfer increase. “API calls can multiply, exceptions and edge cases appear at volume that might have been out of scope for the pilot phase, and then support overheads just grow as well,” he adds.

To prevent this, organisations must track the marginal cost at scale. This involves monitoring unit economics, such as the cost per customer served or cost per transaction. If the cost per customer increases as the customer base grows, the business model is flawed.

Conversely, effective scaling should see these unit costs decrease. Holmes cites a case study from Liberty Mutual where the insurer was able to find around $2.5 million of savings by bringing in consumption metrics and “not just looking at labour hours that they were saving.”

However, financial accountability cannot sit solely with the finance department. Holmes advocates for putting governance “back in the hands of the developers into their development tools and workloads.”

Integration with infrastructure-as-code tools like HashiCorp Terraform and GitHub allows organisations to enforce policies during deployment. Teams can spin up resources programmatically with immediate cost estimates.

“Rather than deploying things and then fixing them up, which gets into the whole whack-a-mole kind of problem,” Holmes explains, companies can verify they are “deploying the right things at the right time.”

When scaling intelligent automation, tension often simmers between the CFO, who focuses on return on investment, and the Head of Automation, who tracks operational metrics like hours saved.

“This translation challenge is precisely what TBM (Technology Business Management) and Apptio are designed to solve,” says Holmes. “It’s having a common language between technology and finance and with the business.”

The TBM taxonomy provides a standardised framework to reconcile these views. It maps technical resources (such as compute, storage, and labour) into IT towers and further up to business capabilities. This structure translates technical inputs into business outputs.

“I don’t necessarily know what goes into all the IT layers underneath it,” Holmes says, describing the business user’s perspective. “But because we’ve got this taxonomy, I can get a detailed bill that tells me about my service consumption and precisely which costs are driving  it to be more expensive as I consume more.”

Addressing legacy debt and budgeting for the long-term

Organisations burdened by legacy ERP systems face a binary choice: automation as a patch, or as a bridge to modernisation. Holmes warns that if a company is “just trying to mask inefficient processes and not redesign them,” they are merely “building up more technical debt.”

A total cost of ownership (TCO) approach helps determine the correct strategy. The Commonwealth Bank of Australia utilised a TCO model across 2,000 different applications – of various maturity stages – to assess their full lifecycle costs. This analysis included hidden costs such as infrastructure, labour, and the engineering time required to keep automation running.

“Just because of something’s legacy doesn’t mean you have to retire it,” says Holmes. “Some of those legacy systems are worth maintaining just because the value is so good.”

In other cases, calculating the cost of the automation wrappers required to keep an old system functional reveals a different reality. “Sometimes when you add up the TCO approach, and you’re including all these automation layers around it, you suddenly realise, the real cost of keeping that old system alive is not just the old system, it’s those extra layers,” Holmes argues.

Avoiding sticker shock requires a budgeting strategy that balances variable costs with long-term commitments. While variable costs (OPEX) offer flexibility, they can fluctuate wildly based on demand and engineering efficiency.

Holmes advises that longer-term visibility enables better investment decisions. Committing to specific technologies or platforms over a multi-year horizon allows organisations to negotiate economies of scale and standardise architecture.

“Because you’ve made those longer term commitments and you’ve standardised on different platforms and things like that, it makes it easier to build the right thing out for the long term,” Holmes says.

Combining tight management of variable costs with strategic commitments supports enterprises in scaling intelligent automation without the volatility that often derails transformation.

IBM is a key sponsor of this year’s Intelligent Automation Conference Global in London on 4-5 February 2026. Greg Holmes and other experts will be sharing their insights during the event.

FedEx tests how far AI can go in tracking and returns management

Published

on

FedEx is using AI to change how package tracking and returns work for large enterprise shippers. For companies moving high volumes of goods, tracking no longer ends when a package leaves the warehouse. Customers expect real-time updates, flexible delivery options, and returns that do not turn into support tickets or delays.

That pressure is pushing logistics firms to rethink how tracking and returns operate at scale, especially across complex supply chains.

This is where artificial intelligence is starting to move from pilot projects into daily operations.

FedEx plans to roll out AI-powered tracking and returns tools designed for enterprise shippers, according to a report by PYMNTS. The tools are aimed at automating routine customer service tasks, improving visibility into shipments, and reducing friction when packages need to be rerouted or sent back.

Rather than focusing on consumer-facing chatbots, the effort centres on operational workflows that sit behind the scenes. These are the systems enterprise customers rely on to manage exceptions, returns, and delivery changes without manual intervention.

How FedEx is applying AI to package tracking

Traditional tracking systems tell customers where a package is and when it might arrive. AI-powered tracking takes a step further by utilising historical delivery data, traffic patterns, weather conditions, and network constraints to flag potential delays before they happen.

According to the PYMNTS report, FedEx’s AI tools are designed to help enterprise shippers anticipate issues earlier in the delivery process. Instead of reacting to missed delivery windows, shippers may be able to reroute packages or notify customers ahead of time.

For businesses that ship thousands of parcels per day, that shift matters. Small improvements in prediction accuracy can reduce support calls, lower refund rates, and improve customer trust, particularly in retail, healthcare, and manufacturing supply chains.

This approach also reflects a broader trend in enterprise software, in which AI is being embedded into existing systems rather than introduced as standalone tools. The goal is not to replace logistics teams, but to minimise the number of manual decisions they need to make.

Returns as an operational problem, not a customer issue

Returns are one of the most expensive parts of logistics. For enterprise shippers, particularly those in e-commerce, returns affect warehouse capacity, inventory planning, and transportation costs.

According to PYMNTS, FedEx’s AI-enabled returns tools aim to automate parts of the returns process, including label generation, routing decisions, and status updates. Companies that use AI to determine the most efficient return path may be able to reduce delays and avoid returning things to the wrong facility.

This is less about convenience and more about operational discipline. Returns that sit idle or move through the wrong channel create cost and uncertainty across the supply chain. AI systems trained on past return patterns can help standardise decisions that were previously handled case by case.

For enterprise customers, this type of automation supports scale. As return volumes fluctuate, especially during peak seasons, systems that adjust automatically reduce the need for temporary staffing or manual overrides.

What FedEx’s AI tracking approach says about enterprise adoption

What stands out in FedEx’s approach is how narrowly focused the AI use case is. There are no broad claims about transformation or reinvention. The emphasis is on reducing friction in processes that already exist.

This mirrors how other large organisations are adopting AI internally. In a separate context, Microsoft described a similar pattern in its article. The company outlined how AI tools were rolled out gradually, with clear limits, governance rules, and feedback loops.

While Microsoft’s case focused on knowledge work and FedEx’s on logistics operations, the underlying lesson is the same. AI adoption tends to work best when applied to specific activities with measurable results rather than broad promises of efficiency.

For logistics firms, those advantages include fewer delivery exceptions, lower return handling costs, and better coordination between shipping partners and enterprise clients.

What this signals for enterprise customers

For end-user companies, FedEx’s move signals that logistics providers are investing in AI as a way to support more complex shipping demands. As supply chains become more distributed, visibility and predictability become harder to maintain without automation.

AI-driven tracking and returns could also change how businesses measure logistics performance. Companies may focus less on delivery speed and more on how quickly issues are recognised and resolved.

That shift could influence procurement decisions, contract structures, and service-level agreements. Enterprise customers may start asking not just where a shipment is, but how well a provider anticipates problems.

FedEx’s plans reflect a quieter phase of enterprise AI adoption. The focus is less on experimentation and more on integration. These systems are not designed to draw attention but to reduce noise in operations that customers only notice when something goes wrong.
