Smart rings that can track your sleep, fitness, and could save your life
While smartwatches have reigned supreme as a wearable tech for the past few years, smart rings are all the rage now. Samsung’s Galaxy Ring was the first of the major smartphone manufacturers to add to the smart ring space, and while it’s the first major brand, it’s not the first smart ring to hit the market. A few smart rings, like the Oura Ring, have been out for a few years, which means they are largely free of bugs and tried and tested in 2024.
Smart rings track the same things smartwatches do, such as steps, sleep and a general overview of your overall health. They tend to have significantly more battery life than smartwatches, with no distracting screen. Like smartwatches, the best smart rings on the market can even help save your life with proper vitals tracking and notification systems to alert you when something is wrong.
Here are my three favorite smart rings that can track your fitness and could even save your life.

OUR TOP RECOMMENDATIONS FOR KIDS’ SMARTWATCHES AND TRACKING TOOLS
The best ring for most people
Oura Ring 4
If you’re looking for one of the best smart rings on the market that will do everything you want with a simple setup, consider the Oura Ring 4. It’s a brand-new release that began shipping Oct. 15 and can be ordered for $350, which is $50 more expensive than the prior Oura Ring 3. It comes in four different colors and four different size options.
WHAT IS ARTIFICIAL INTELLIGENCE (AI)?

The Oura Ring 4 packs a suite of fitness-focused features such as a workout heart rate tracker, which can be synced with Oura’s desktop and mobile app to show detailed analysis of your burned calories, active and inactive time, and heart rate. One of the most celebrated features of the Oura Ring 4 is its outstanding sleep tracking, which can measure and log your nighttime temperature changes, blood oxygen levels, and sleep cycle stages.
It does come at an expensive price point, though, at $350. We’ve seen Oura Ring prices go up every revision, and I think Oura has done an excellent job justifying the new price point with new features. It’s worth considering it’s only a $50 price increase from the Oura Ring 3, and it’s the better ring. One downside, however, to the Oura Ring 4 is you will need to pay an additional $6 for the Oura Ring subscription service, which is how you store your ring’s analytics.

The best smart ring for Android phone users
Samsung Galaxy Ring
If you own an Android phone, the Samsung Galaxy ring is the best option for a smart ring. Priced at $400, Samsung’s Galaxy Ring was released in the summer of 2024, and it has many of the same features as the Oura Ring 4. However, unlike the Oura Ring 4, the Galaxy Ring takes sleep tracking a step further. Samsung has developed its own AI algorithm to determine your sleep patterns, all while offering a daily sleep score.

Your health data will be stored in the Galaxy Health App, which you can use directly from your Android smartphone. It’s important to note that the Galaxy Ring is only compatible with the Android operating system. IOS owners, unfortunately, don’t have access to the Galaxy Health app. The Galaxy Ring is compatible with other devices in the Samsung gadget ecosystem. This means that if you have a Samsung smartwatch, it will share data with your Galaxy Ring. However, this compatibility comes at a cost, and this is the most expensive smart ring on this list, at $400.
SKYROCKET TO A HEALTHIER LIFESTYLE WITH THIS GEAR IN 2024
The best smart ring on a budget
RingConn Gen 1
The RingConn Gen 1 offers some of the high-end features of the Oura rings without the monthly subscription fee. It’s also the cheapest smart ring on this list, at $280, but it’s frequently on sale. It comes in three different colors and 10 different sizing options, allowing it to be worn on fingers of all sizes.

The RingConn Gen 1 features stress and general wellness tracking. It also has a sleep tracker, activity counter and vitals tracking, such as a heart rate tracker, a blood oxygen monitor and temperature sensors. Reviewers have noted that while the health information tracking with the RingConn Gen 1 is great, the activity tracker could be more exact. You also don’t get as many features as you would with the competing Oura brand of smart rings, but you also save a bit of money off the top and the subscription fee.
Overall, the RingConn Gen 1 is a great entry-level smart ring. It’s not as feature-packed as some of the competitors, but it’s priced well and is an excellent way to see if a smart ring is for you. You can always upgrade to a different smart ring if you like the RingConn Gen 1, but I think it’s a great starting point for most people in the world of smart rings.

Defense secretary Pete Hegseth designates Anthropic a supply chain risk
This week, Anthropic delivered a master class in arrogance and betrayal as well as a textbook case of how not to do business with the United States Government or the Pentagon.
Our position has never wavered and will never waver: the Department of War must have full, unrestricted access to Anthropic’s models for every LAWFUL purpose in defense of the Republic.
Instead, @AnthropicAI and its CEO @DarioAmodei, have chosen duplicity. Cloaked in the sanctimonious rhetoric of “effective altruism,” they have attempted to strong-arm the United States military into submission – a cowardly act of corporate virtue-signaling that places Silicon Valley ideology above American lives.
The Terms of Service of Anthropic’s defective altruism will never outweigh the safety, the readiness, or the lives of American troops on the battlefield.
Their true objective is unmistakable: to seize veto power over the operational decisions of the United States military. That is unacceptable.
As President Trump stated on Truth Social, the Commander-in-Chief and the American people alone will determine the destiny of our armed forces, not unelected tech executives.
Anthropic’s stance is fundamentally incompatible with American principles. Their relationship with the United States Armed Forces and the Federal Government has therefore been permanently altered.
In conjunction with the President’s directive for the Federal Government to cease all use of Anthropic’s technology, I am directing the Department of War to designate Anthropic a Supply-Chain Risk to National Security. Effective immediately, no contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic. Anthropic will continue to provide the Department of War its services for a period of no more than six months to allow for a seamless transition to a better and more patriotic service.
America’s warfighters will never be held hostage by the ideological whims of Big Tech. This decision is final.

What Trump’s ‘ratepayer protection pledge’ means for you
NEWYou can now listen to Fox News articles!
When you open a chatbot, stream a show or back up photos to the cloud, you are tapping into a vast network of data centers. These facilities power artificial intelligence, search engines and online services we use every day. Now there is a growing debate over who should pay for the electricity those data centers consume.
During President Trump’s State of the Union address this week, he introduced a new initiative called the “ratepayer protection pledge” to shift AI-driven electricity costs away from consumers. The core idea is simple.
Tech companies that run energy-intensive AI data centers should cover the cost of the extra electricity they require rather than passing those costs on to everyday customers through higher utility rates.
It sounds simple. The hard part is what happens next.

Why AI is driving a surge in electricity demand
AI systems require enormous computing power. That computing power requires enormous electricity. Today’s data centers can consume as much power as a small city. As AI tools expand across business, healthcare, finance and consumer apps, energy demand has risen sharply in certain regions.
Utilities have warned that the current grid in many parts of the country was not built for this level of concentrated demand. Upgrading substations, transmission lines and generation capacity costs money. Traditionally, those costs can influence rates paid by homes and small businesses. That is where the pledge comes in.
What the ratepayer protection pledge is designed to do
Under the ratepayer protection pledge, large technology companies would:
- Cover the full cost of additional electricity tied to their data centers
- Build their own on-site power generation to reduce strain on the public grid
Supporters say this approach separates residential energy costs from large-scale AI expansion. In other words, your household bill should not rise simply because a new AI data center opens nearby. So far, Anthropic is the clearest public backer. CyberGuy reached out to Anthropic for a comment on its role in the pledge. A company spokesperson referred us to a tweet from Anthropic Head of External Affairs Sarah Heck.
“American families shouldn’t pick up the tab for AI,” Heck wrote in a post on X. “In support of the White House ratepayer protection pledge, Anthropic has committed to covering 100% of electricity price increases that consumers face from our data centers.”
That makes Anthropic one of the first major AI companies to publicly state it will absorb consumer electricity price increases tied to its data center operations. Other major firms may be close behind. The White House reportedly plans to host Microsoft, Meta and Anthropic in early March to discuss formalizing a broader deal, though attendance and final terms have not been confirmed publicly.
Microsoft also expressed support for the initiative.
“The ratepayer protection pledge is an important step,” Brad Smith, Microsoft vice chair and president, said in a statement to CyberGuy. “We appreciate the administration’s work to ensure that data centers don’t contribute to higher electricity prices for consumers.”
Industry groups also point to companies such as Google and utilities including Duke Energy and Georgia Power as making consumer-focused commitments tied to data center growth. However, enforcement mechanisms and long-term regulatory details remain unclear.

How this could change the economics of AI
AI infrastructure is already one of the most expensive technology buildouts in history. Companies are investing billions in chips, servers and real estate. If firms must also finance dedicated power plants or pay premium rates for grid upgrades, the cost of running AI systems increases further. That could lead to:
- Slower expansion in some markets
- Greater investment in renewable energy and storage
- More partnerships between tech firms and utilities
Energy strategy may become just as important as computing strategy. For consumers, this shift signals that electricity is now a central part of the AI conversation. AI is no longer only about software. It is also about infrastructure.
The bigger consumer tech picture
AI is becoming embedded in smartphones, search engines, office software and home devices. As adoption grows, so does the hidden infrastructure supporting it. Energy is now part of the conversation around everyday technology. Every AI-generated image, voice command or cloud backup depends on a power-hungry network of servers.
By asking companies to account more directly for their electricity use, policymakers are acknowledging a new reality. The digital world runs on very physical resources. For you, that shift could mean more transparency. It also raises new questions about sustainability, local impact and long-term costs.

What this means for you
If you are a homeowner or renter, the practical question is simple. Will this protect my electric bill? In theory, separating data center energy costs from residential rates could reduce the risk of price spikes tied to AI growth. If companies fund their own generation or grid upgrades, utilities may have less reason to spread those costs among all customers.
That said, utility pricing is complex. It depends on state regulators, long-term planning and local energy markets.
Here is what you can watch for in your area:
- New data center construction announcements
- Utility filings that mention large commercial load growth
- Public service commission decisions on rate adjustments
Even if you rarely use AI tools, your community could feel the effects of a nearby data center. The pledge is intended to keep those large-scale power demands from showing up in your monthly bill.

Kurt’s key takeaways
The ratepayer protection pledge highlights an important turning point. AI is no longer only about innovation and speed. It is also about energy and accountability. If tech companies truly absorb the cost of their expanding power needs, households may avoid some of the financial strain tied to rapid AI growth. If not, utility bills could become an unexpected front line in the AI era.

Here’s your first look at Kratos in Amazon’s God of War show
Amazon has slowly been teasing out casting details for its live-action adaptation of God of War, and now we have our first look at the show. It’s a single image but a notable one showing protagonist Kratos and his son Atreus. The characters are played by Ryan Hurst and Callum Vinson, respectively, and they look relatively close to their video game counterparts.
There aren’t a lot of other details about the show just yet, but this is Amazon’s official description:
The God of War series storyline follows father and son Kratos and Atreus as they embark on a journey to spread the ashes of their wife and mother, Faye. Through their adventures, Kratos tries to teach his son to be a better god, while Atreus tries to teach his father how to be a better human.
That sounds a lot like the recent soft reboot of the franchise, which started with 2018’s God of War and continued through Ragnarök in 2022. For the Amazon series, Ronald D. Moore, best-known for his work on For All Mankind and Battlestar Galactica, will serve as showrunner. The rest of the cast includes: Mandy Patinkin (Odin), Ed Skrein (Baldur), Max Parker (Heimdall), Ólafur Darri Ólafsson (Thor), Teresa Palmer (Sif), Alastair Duncan (Mimir), Jeff Gulka (Sindri), and Danny Woodburn (Brok).
While production is underway on the God of War series, there’s no word on when it might start streaming.
