The Bitcoin Spot ETFs continue to witness a volatile start to 2026, with back-to-back weeks showing sharply contrasting performance. After netting a staggering $1.42 billion in weekly netflows on January 16, market momentum soon swung the opposite way in line with a Bitcoin decline, forcing a net outflow of $1.33 billion over the last week. A similar phenomenon was seen in the first two weeks of the year, after an initial net deposit of $458.77 million by January 2 was followed by a net outflow of $681.01 million by January 9. This investor behavior suggests a highly reactive market with little long-term confidence.
No Positive Performance In Bitcoin Spot ETF Market Onslaught
In analyzing the most recent wave of withdrawals in the Bitcoin Spot ETF market, data from SoSoValue shows that the fourth trading week of January recorded no single day with a positive netflow. The heaviest outflows totaled $708.71 million on January 21, followed by the smallest daily outflow of $32.11 million on January 22.
Looking at individual funds, BlackRock’s IBIT, the market leader, suffered the largest net outflows valued at $537.49 million. As usual, Fidelity’s FBTC ranks a close second with redemptions surpassing deposits by $451.50 million. Other Bitcoin Spot ETFs with heavy net outflows also included Grayscale’s GBTC, Bitwise’s BITB, and Ark Invest’s ARKB, which suffered losses estimated at $172.09 million, $66.25 million, and $76.19 million, respectively.
Meanwhile, VanEck’s HODL, Valkyrie’s BRRR, and Franklin Templeton’s EZBC also experienced net outflows between $6 million and $11 million. Notably, Grayscale’s BTC, Invesco’s BTCO, WisdomTree’s BTCW, and Hashdex’s DEFI recorded the least activity with zero netflows. At press time, total net assets for the Bitcoin Spot ETFs stand at $115.88 billion, with BlackRock’s IBIT accounting for over 54% of these holdings, as the undisputed market leader. Meanwhile, total cumulative net inflow is presently valued at $56.49 billion.
Ethereum Spot ETFs Register $611M Outflows In Market Bloodbath
According to more data from SoSoValue, the Ethereum Spot ETFs also witnessed massive levels of redemptions in the last trading week, resulting in a net outflow of $611.17 million. Similar to its Bitcoin counterpart, the BlackRock ETHA also produced the largest net withdrawals valued at $431.50 million. Presently, the total net assets for the Ethereum Spot ETFs are valued at $17.70 billion, representing 4.99% of Ethereum’s market cap. Meanwhile, the cumulative total net inflow is valued at $12.30 billion.
CIO magazine reports that "the push toward in-person work environments will make it more difficult for IT leaders to retain and recruit staff, some experts say."
"In addition to resistance, there would also be the risk of talent turnover," [says Lawrence Wolfe, CTO at marketing firm Converge]... "The truth is, both physical and virtual collaboration provide tremendous value...." IT workers facing work-from-office mandates are two to three times more likely than their counterparts to look for new jobs, according to Metaintro, a search engine that tracks millions of jobs. IT leaders hiring new employees may also face significant headwinds, with it taking 40% to 50% longer to fill in-person roles than remote jobs, according to Metaintro. "Some of the challenges CIOs face include losing top-tier talent, limiting the pool of candidates available for hire, and damaging company culture, with a team filled with resentment," says Lacey Kaelani, CEO and cofounder at Metaintro...
There are several downsides for IT leaders to in-person work mandates, [adds Lena McDearmid, founder and CEO of culture and leadership advisory firm Wryver], as orders to commute to an office can feel arbitrary or rooted in control rather than in value creation. "That erodes trust quickly, particularly in IT teams that proved they could deliver remotely for years," she adds. The mandates can also create new friction for IT leaders by requiring them to deal with morale issues, manage exceptions, and spend time enforcing policy instead of leading strategy, she says. "There's also a real risk of losing experienced, high-performing talent who have options and are unwilling to trade autonomy for proximity without a clear reason," McDearmid adds. "When companies mandate daily commutes without a clear rationale, they often narrow their talent pool and increase attrition, particularly among people who know they can work effectively elsewhere."
McDearmid has seen teams "sitting next to each other" who collaborate poorly "because decisions are unclear or leaders equate visibility with progress... Collaboration doesn't automatically improve just because people share a building."
And Rebecca Wettemann, CEO at IT analyst firm Valoir, warns of return-to-office mandates "being used as a Band-Aid for poor management. When IT professionals feel they're being evaluated based on badge swipes, not real accomplishments, they will either act accordingly or look to work elsewhere."

Bitcoin’s price is fluctuating below the $90,000 mark as volatility increases across the entire cryptocurrency market. During the bearish price action, attention is now being shifted to the cautious signal from the Bitcoin Open Interest in BTC terms, which has remained below past all-time high in years.
Open Interest Tells A Different Story When Measured In BTC
Amid the ongoing volatile action of the crypto market, the derivatives market for Bitcoin is providing a more subdued message. This message is unfolding on the Bitcoin Open Interest (OI) in BTC terms as outlined in a recent research by Joao Wedson, a market expert and founder of the Alphractal analytics platform.
In the report shared on the X platform, the market expert highlighted that the open interest measured in BTC terms has failed to reach new all-time highs since 2022. The BTC-based perspective shows a more restricted usage of leverage over cycles, whereas dollar-denominated measures frequently climb in tandem with price.
On Thursday, the metric experienced a bounce, but Wedson stated that the upward move was mainly in USD-dominated open interest. This pattern suggests that traders are becoming more cautious in the market by allocating capital more carefully as opposed to putting it all into risky positions.
According to the expert, the trend simply suggests that speculation is present in the market and it’s currently expanding. However, the chart shows that the broader market is still far from any form of extreme or irrational euphoria.
Not Enough Profit To Trigger A Bullish Recovery
BTC’s inability to produce another major rally is linked to the level of investors in profit. Darkfost stated that there are still not enough investors in profit to hope for a sustainable bullish recovery. Thus, it is crucial to understand that latent profits are not harmful to a market; it is quite the opposite.
When investors are most in profit, the situation is much more comfortable, which motivates them to hold. However, this only holds up to a certain point. Also, when the supply in profit surpasses 95% or even 100%, latest profits begin to impact the market and may trigger essential corrective phases.
The ongoing correction remained moderate with a drawdown to around 31%, but it was able to sharply reduce the percentage of supply in profit, suggesting very late entry by many investors. Currently, over 71% of BTC is in profit after dropping as low as 64%, a very concerning level that has typically been observed only when Bitcoin was entering a bear market.
However, in Darkfost’s view, the market must reclaim above 75% supply in profit to regain a more stable structure. As long as it stays above this level, the supply in profit has historically been associated with positive periods, as shown in the chart.
With the recent price rebound, the supply in profit saw a brief climb back to 75% before getting rejected. Meanwhile, many BTC investors possibly used this opportunity to exit at break-even or to cut their losses.
One of the more seamless aspects on a recent trip to Japan was being able to simply “tap” my iPhone to pay for subway rides in Tokyo. That frictionless transit payment capability, common in many major cities worldwide, isn’t available in Seattle. But that’s about to change.
Seattle’s ORCA transit system is rolling out an upgrade that will let riders pay fares by tapping their credit card or smartphone — no dedicated ORCA card required.
The new “Tap to Pay” feature will let riders across the Seattle region use Visa, Mastercard, Discover, or American Express cards, as well as mobile wallets such as Apple Pay, Google Pay, and Samsung Pay.
A soft launch is scheduled to begin Feb. 2 on the G Line, a bus rapid transit route, before expanding system-wide later in February — in advance of this summer’s World Cup in Seattle, as well as the debut of the new light rail line across Lake Washington connecting the region’s tech hubs.
The Tap to Pay rollout was formally briefed to the ORCA Joint Board during its meeting this week.
The technical upgrade is aimed at making transit easier for occasional riders, tourists, and anyone who doesn’t already carry an ORCA card — while modernizing fare payment across the region’s patchwork of transit agencies.
ORCA’s operations team worked with German tech company Init to implement Visa’s Mass Transit Transaction (MTT) payment model, which allows ORCA fare readers to function as point-of-sale devices capable of securely processing contactless credit card payments in real time.
During the soft-launch phase, riders who tap a personal credit or debit card will be charged a flat $3 adult fare and won’t be able to transfer to other transit services outside the G Line. Once the feature launches across the full ORCA system, transfers will work the same way they do today for ORCA card users, including the standard two-hour transfer window across most participating agencies, according to ORCA officials.
The system will support one rider per card and adult fares only, meaning reduced-fare programs such as ORCA LIFT, Senior, Disabled, and Youth cards won’t be available through Tap to Pay.
Fare inspectors will be able to validate contactless payments by asking riders to show whatever card they used to pay.
In a statement to GeekWire, ORCA officials emphasized that the new payment option is additive, not a replacement. Riders who receive employer-subsidized ORCA cards or rely on discounted fares are encouraged to continue using traditional ORCA cards. Cash and physical tickets will still be accepted.
Tap to Pay also won’t be available on every service. The feature will not initially work on Washington State Ferries, the Seattle Monorail, Community Transit DART, ZIP, or Pierce Transit Runner, according to board presentation slides.
Some users on Reddit this week complained about needing to remove their physical ORCA card from their wallet to avoid getting a credit card charge when tapping at a reader.
Notably, using an ORCA card inside Apple Wallet is a separate feature and is not part of this launch. ORCA officials said they remain committed to mobile payment options but declined to share additional details or timelines. ORCA launched a Google Wallet feature for Android users in 2024.
Side note: Apple Wallet has a feature called Express Mode that lets transit riders pay for fares without waking or unlocking their device.
And for those who want to purchase tickets via an app: Transit GO allows iOS and Android users to pay fares on King Country Metro buses, Sound Transit trains, and other regional transit services using in-app ticketing.

The date is set for a transportation milestone that could impact how thousands of Seattle-area commuters travel between home and work, especially at the region’s major tech hubs.
Sound Transit announced Friday that the “Crosslake Connection” of the Link light rail system will open to the public on March 28.
The route will carry light rail passengers across a floating bridge for the first time, serving as a 7.4-mile extension of the 2 Line and ultimately connecting downtown Seattle to downtown Bellevue and the Redmond Technology station at Microsoft’s headquarters campus.
Are you a tech worker looking forward to using light rail to commute between Seattle and the Eastside? We’d love to hear from you: tips@geekwire.com
Testing of trains on the bridge, between new stations at Mercer Island and Judkins Park, began in September. A 6.6-mile East Link segment of the 2 Line, including eight stations, opened last April.
The entire Seattle-Eastside line — plagued by planning, construction and cost issues — has taken nearly 18 years to deliver, The Seattle Times noted after a test ride this week.
The region has changed substantially in that time.
The tech boom and subsequent population explosion in Seattle clogged area roadways, turning a roughly 13-mile commute between Seattle and Microsoft HQ into an often time-consuming headache.
Bellevue has also grown, thanks in part to Amazon, as the tech giant has shifted thousands of workers to various buildings in that city. Roughly 50,000 corporate employees work in Seattle.
While Microsoft, Amazon, Expedia and other companies run private buses between offices in Seattle and Eastside cities for their employees, light rail service adds another wrinkle to the commute landscape.
Sound Transit projects that the fully integrated 2 Line will serve about 43,000 to 52,000 daily riders in 2026.
Trains over Lake Washington will operate at speeds of 55 mph, running every 10 minutes from approximately 5 a.m. to 1 a.m., Monday – Saturday and from 6 a.m. to midnight on Sundays.
It’s no small engineering feat to run tracks and get a train to cross a floating bridge. The Seattle Times explained some of the challenges related to fluctuating lake levels and existing bridge infrastructure. This video also breaks down what goes into it:

Bitcoin is facing a critical test as volatility returns and price action remains unstable around the $90,000 level. Bulls are attempting to defend this psychological zone after recent turbulence, but confidence across the market is still fragile. With uncertainty dominating short-term sentiment, many traders are treating every bounce as a potential trap rather than the start of a confirmed recovery.
According to top analyst Darkfost, the market is still missing a key ingredient for a sustainable bullish continuation: a broad base of investors sitting in profit. He argues that despite Bitcoin’s resilience, there are not yet enough participants in positive territory to build the kind of structural comfort that fuels long-lasting uptrends.
This matters because latent profits are not inherently bearish. In healthy conditions, when most holders are in profit, the market tends to stabilize. Investors feel less pressure to sell, panic fades, and holding becomes easier. That environment often supports stronger trend development and reduces the risk of sharp downside reactions.
Still, Darkfost warns that profit dynamics only help up to a point. When unrealized gains become extreme across the entire market, they can eventually turn into overhead supply, triggering corrective phases.
Bitcoin’s Profit Structure Still Isn’t Bullish Enough
Profit distribution across holders can become a double-edged sword for Bitcoin. When the supply in profit climbs above 95% and approaches 100%, unrealized gains stop being supportive and begin turning into overhead pressure. At those extremes, investors have little incentive to hold through volatility, and even small shocks can trigger profit-taking that fuels corrective phases.
From a structural perspective, Darkfost argues the market needs to reclaim the 75% supply-in-profit threshold to rebuild a healthier foundation. Historically, Bitcoin has tended to sustain bullish conditions when this metric holds above that level, as most participants remain comfortable and less reactive to downside volatility.
Right now, however, the market sits near 71%, after dropping as low as 64%. Darkfost notes that readings this low have often appeared near the early stages of bear markets, even when the headline drawdown looks relatively contained. In this case, the decline of roughly 31% was enough to push a large portion of recent buyers underwater, suggesting many entered late in the move.
The recent rebound briefly lifted supply in profit back to 75%, but it failed to hold. That rejection likely reflects investors using the bounce to exit at breakeven or reduce losses. Going forward, reclaiming 75%–80% would signal stabilization, while further weakness could amplify panic-driven selling.
Volatility Keeps Bulls on the Defensive
Bitcoin is attempting to stabilize near the $90,000 mark after a volatile correction that reshaped the market structure over the past few months. The chart shows BTC printing a major peak around $125,000 before rolling over into a sharp selloff. Accelerating into November and eventually finding a local floor near the mid-$80,000s. That drop marked a decisive break in momentum and triggered a shift toward a lower range, where price has struggled to regain prior support levels.
Since the rebound off the lows, Bitcoin has moved into a consolidation phase, repeatedly testing resistance around $92,000–$95,000 but failing to generate sustained continuation. Each recovery attempt has been met with selling pressure, suggesting that short-term supply is still active near former breakdown zones. The latest bounce back toward $90,000 signals buyers are defending the level. But the structure still looks fragile without a clean breakout.
Volume also reflects uncertainty, with higher activity during selloffs and more muted participation during rebounds. Bulls likely need to hold $88,000–$90,000 and reclaim the $92,000 region with conviction.

The project developer for one of the Internet’s most popular networking tools is scrapping its vulnerability reward program after being overrun by a spike in the submission of low-quality reports, much of it AI-generated slop.
“We are just a small single open source project with a small number of active maintainers,” Daniel Stenberg, the founder and lead developer of the open source app cURL, said Thursday. “It is not in our power to change how all these people and their slop machines work. We need to make moves to ensure our survival and intact mental health.”
Manufacturing bogus bugs
His comments came as cURL users complained that the move was treating the symptoms caused by AI slop without addressing the cause. The users said they were concerned the move would eliminate a key means for ensuring and maintaining the security of the tool. Stenberg largely agreed, but indicated his team had little choice.
On Tuesday, eBay updated its User Agreement to explicitly ban third-party "buy for me" agents and AI chatbots from interacting with its platform without permission, first spotted by Value Added Resource. On its face, a one-line terms of service update doesn't seem like major news, but what it implies is more significant: The change reflects the rapid emergence of what some are calling "agentic commerce," a new category of AI tools designed to browse, compare, and purchase products on behalf of users.
eBay's updated terms, which go into effect on February 20, 2026, specifically prohibit users from employing "buy-for-me agents, LLM-driven bots, or any end-to-end flow that attempts to place orders without human review" to access eBay's services without the site's permission. The previous version of the agreement contained a general prohibition on robots, spiders, scrapers, and automated data gathering tools but did not mention AI agents or LLMs by name.
At first glance, the phrase "agentic commerce" may sound like aspirational marketing jargon, but the tools are already here, and people are apparently using them. While fitting loosely under one label, these tools come in many forms.
NASA's first astronauts to fly to the Moon in more than 50 years will pay tribute to the lunar and space exploration missions that preceded them, as well as aviation and American history, by taking with them artifacts and mementos representing those past accomplishments.
NASA, on Wednesday, January 21, revealed the contents of the Artemis II mission's Official Flight Kit (OFK), continuing a tradition dating back to the Apollo program of packing a duffel bag-sized pouch of symbolic and celebratory items to commemorate the flight and recognize the people behind it. The kit includes more than 2,300 items, including a handful of relics.
"This mission will bring together pieces of our earliest achievements in aviation, defining moments from human spaceflight and symbols of where we're headed next," Jared Isaacman, NASA's administrator, said in a statement. "Historical artifacts flying aboard Artemis II reflect the long arc of American exploration and the generations of innovators who made this moment possible."
There’s little about building spacecraft that anyone would call simple. But there’s at least one element of designing a vehicle that will operate outside the Earth’s atmosphere that’s fairly easier to handle: aerodynamics. That’s because, at the altitude that most satellites operate at, drag can essentially be ignored. Which is why most satellites look like refrigerators with solar panels and high-gain antennas attached jutting out at odd angles.
But for all the advantages that the lack of meaningful drag on a vehicle has, there’s at least one big potential downside. If a spacecraft is orbiting high enough over the Earth that the impact of atmospheric drag is negligible, then the only way that vehicle is coming back down in a reasonable amount of time is if it has the means to reduce its own velocity. Otherwise, it could be stuck in orbit for decades. At a high enough orbit, it could essentially stay up forever.
Launched in 1958, Vanguard 1 is expected to remain in orbit until at least 2198
There was a time when that kind of thing wasn’t a problem. It was just enough to get into space in the first place, and little thought was given to what was going to happen in five or ten years down the road. But today, low Earth orbit is getting crowded. As the cost of launching something into space continues to drop, multiple companies are either planning or actively building their own satellite constellations comprised of thousands of individual spacecraft.
Fortunately, there may be a simple solution to this problem. By putting a satellite into what’s known as a very low Earth orbit (VLEO), a spacecraft will experience enough drag that maintaining its velocity requires constantly firing its thrusters. Naturally this presents its own technical challenges, but the upside is that such an orbit is essentially self-cleaning — should the craft’s propulsion fail, it would fall out of orbit and burn up in months or even weeks. As an added bonus, operating at a lower altitude has other practical advantages, such as allowing for lower latency communication.
VLEO satellites hold considerable promise, but successfully operating in this unique environment requires certain design considerations. The result are vehicles that look less like the flying refrigerators we’re used to, with a hybrid design that features the sort of aerodynamic considerations more commonly found on aircraft.
ESA’s Pioneering Work
This might sound like science fiction, but such craft have already been developed and successfully operated in VLEO. The best example so far is the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE), launched by the European Space Agency (ESA) back in 2009.
To make its observations, GOCE operated at an altitude of 255 kilometers (158 miles), and dropped as low as just 229 km (142 mi) in the final phases of the mission. For reference the International Space Station flies at around 400 km (250 mi), and the innermost “shell” of SpaceX’s Starlink satellites are currently being moved to 480 km (298 mi).
Given the considerable drag experienced by GOCE at these altitudes, the spacecraft bore little resemblance to a traditional satellite. Rather than putting the solar panels on outstretched “wings”, they were mounted to the surface of the dart-like vehicle. To keep its orientation relative to the Earth’s surface stable, the craft featured stubby tail fins that made it look like a futuristic torpedo.
Even with its streamlined design, maintaining such a low orbit required GOCE to continually fire its high-efficiency ion engine for the duration of its mission, which ended up being four and a half years.
In the case of GOCE, the end of the mission was dictated by how much propellant it carried. Once it had burned through the 40 kg (88 lb) of xenon onboard, the vehicle would begin to rapidly decelerate, and ground controllers estimated it would re-enter the atmosphere in a matter of weeks. Ultimately the engine officially shutdown on October 21st, and by November 9th, it’s orbit had already decayed to 155 km (96 mi). Two days later, the craft burned up in the atmosphere.
JAXA Lowers the Bar
While GOCE may be the most significant VLEO mission so far from a scientific and engineering standpoint, the current record for the spacecraft with the lowest operational orbit is actually held by the Japan Aerospace Exploration Agency (JAXA).
In December 2017 JAXA launched the Super Low Altitude Test Satellite (SLATS) into an initial orbit of 630 km (390 mi), which was steadily lowered in phases over the next several weeks until it reached 167.4 km (104 mi). Like GOCE, SLATS used a continuously operating ion engine to maintain velocity, although at the lowest altitudes, it also used chemical reaction control system (RCS) thrusters to counteract the higher drag.
SLATS was a much smaller vehicle than GOCE, coming in at roughly half the mass. It also carried just 12 kg (26 lb) of xenon propellant, which limited its operational life. It also utilized a far more conventional design than GOCE, although its rectangular shape was somewhat streamlined when compared to a traditional satellite. Its solar arrays were also mounted in parallel to the main body of the craft, giving it an airplane-like appearance.
The combination of lower altitude and higher frontal drag meant that SLATS had an even harder time maintaining velocity than GOCE. Once its propulsion system was finally switched off in October 2019, the craft re-entered the atmosphere and burned up within 24 hours. The mission has since been recognized by Guinness World Records for the lowest altitude maintained by an Earth observation satellite.
A New Breed of Satellite
As impressive as GOCE and SLATS were, their success was based more on careful planning than any particular technological breakthrough. After all, ion propulsion for satellites is not new, nor is the field of aerodynamics. The concepts were simply applied in a novel way.
But there exists the potential for a totally new type of vehicle that operates exclusively in VLEO. Such a craft would be a true hybrid, in the sense that its primarily a spacecraft, but uses an air-breathing electric propulsion (ABEP) system akin to an aircraft’s jet engine. Such a vehicle could, at least in theory, maintain an altitude as low as 90 km (56 mi) indefinitely — so long as its solar panels can produce enough power.
Both the Defense Advanced Research Projects Agency (DARPA) in the United States and the ESA are currently funding several studies of ABEP vehicles, such as Redwire’s SabreSat, which have numerous military and civilian applications. Test flights are still years away, but should VLEO satellites powered by ABEP become common platforms for constellation applications, they may help alleviate orbital congestion before it becomes a serious enough problem to impact our utilization of space.

If you're looking to get fit, sleep better or just keep a closer eye on your health, a fitness wearable is a great place to start. Whether you're into intense workouts or just want to hit your step goal each day, the best fitness trackers available today can offer loads of helpful features, from sleep tracking and resting heart rate monitoring to built-in GPS and stress tracking. Some are even subtle enough to wear 24/7, like smart rings, while others double as stylish smartwatches.
There are great options out there for beginners as well as more advanced users, and the variety of features means there’s something for every lifestyle and budget. In this guide, we’ll walk you through the best fitness trackers you can buy right now, and explain who each one is best suited for.
Best fitness trackers for 2026
What do fitness trackers do best?
The answer seems simple: Fitness wearables are best at monitoring exercise, be it a 10-minute walk around the block or that half marathon you’ve been diligently training for. Obviously, smartwatches can help you reach your fitness goals too, but there are some areas where fitness bands and smart rings have proven to be the best buy: focus, design, better battery life, durability and price.
When I say “focus,” I’m alluding to the fact that fitness trackers are made to track activity well; anything else is extra. They often don’t have the bells and whistles that smartwatches do, which could distract from their advanced health tracking abilities — things like all-day resting heart rate monitoring, stress tracking, and even detailed sleep tracker insights. They also tend to have fewer sensors and internal components, which keeps them smaller and lighter. Fitness trackers are also a better option for those who just want a less conspicuous gadget on their wrists all day.
Battery life tends to be better on fitness trackers, too. While most smartwatches last one to two days on a single charge, fitness bands offer between five and seven days of battery life — and that’s with all-day and all-night use even with sleep tracking features enabled. Many fitness trackers also slot nicely into your existing ecosystem, syncing seamlessly with your smartphone, other fitness apps and cloud storage to keep all your data in one place.
When it comes to price point, there’s no competition. Most worthwhile smartwatches start at $175 to $200, but you can get a solid smart band starting at $70. That makes them a great entry point for beginners who want to track their progress without committing to a full smartwatch. Yes, more expensive bands and smart rings exist (and we recommend a few here), but you’ll find more options under $150 in the fitness tracker space than in the smartwatch space.
When to get a smartwatch instead
If you need a bit more from your wearable and don’t want to be limited to a fitness or activity tracker, a smartwatch may be the best buy for you. There are things like on-watch apps, alerts and even more robust fitness features that smartwatches have and the best fitness trackers don’t. You can use one to control smart home appliances, set timers and reminders, check weather reports and more. Some smartwatches let you choose which apps you want to receive alerts from, and the options go beyond just call and text notifications. Just make sure your smartwatch is compatible with your Android or iPhone, however, before purchasing, as not all of them work with both operating systems.
But the extra fitness features are arguably the most important thing to think about when deciding between a fitness tracker and a smartwatch. The latter devices tend to be larger, giving them more space for things like GPS, barometers, onboard music storage and more. While you can find built-in GPS on select fitness trackers, it’s not common.
If you’re someone who’s seriously training — say for a race or an endurance challenge — a dedicated running watch may be worth considering. These often provide more in-depth cardio analytics, recovery insights, and real-time pace data that go beyond what standard trackers can deliver.
Other fitness trackers we've tested
Fitbit Inspire 3
The Fitbit Inspire 3 strips out all the luxury features from the Charge 6 and keeps only the essential tracking features. You won’t get built-in GPS tracking or Fitbit Pay or Spotify control but you do get solid activity tracking, automatic workout detection, smartphone alerts and plenty more. The updated version has a sleeker design and includes a color touch display and connected GPS, the latter of which lets you track pace and distance while you run or bike outside while you have your phone with you. When compared to the Charge 6, the Inspire 3 is more fashionable, too. Its interchangeable bands let you switch up the look and feel of your tracker whenever you want, and it’s slim enough to blend in with other jewelry you might be wearing. We were also impressed by its multi-day battery life: Fitbit promises up to 10 days on a single charge, and that checked out for us. After four days of round-the-clock use, the Inspire 3 still had 66 percent battery left to go.
Fitness tracker FAQs
How long do fitness tracker batteries last?
The battery life of fitness trackers can vary depending on the model and its features. On average, most fitness trackers last between five to seven days on a single charge. Basic models with limited features could stretch up to 10 days or more. However, more advanced trackers with features like continuous heart rate monitoring, GPS, or always-on displays may need recharging after one to three days. If you're using GPS or streaming music through your fitness tracker, you'll find that this drains the battery faster. By using these features less, or turning them off, you'll extend battery life.

Saga said it stopped the chain at block height 6593800 after identifying a security incident on Jan. 21, and it has kept the network paused “out of an abundance of caution” while it validates the full impact and patches the weakness and reinforces the system.
“We recognize that a pause is disruptive. We made this decision because the safety of our community comes first,” the team said Wednesday in its blog. “Once remediation is complete, we will publish a more comprehensive technical post-mortem.”
SagaEVM remains paused while we finalize the results of our investigation into the Jan 21 exploit.
We’re working with partners on remediation and will publish a post-mortem once findings are fully validated. $7M of USDC was bridged out and converted to ETH.
In its investigation update, Saga said nearly $7M in USDC, yUSD, ETH, and tBTC were transferred to the Ethereum Mainnet, and it identified the wallet it was extracted to.
The team said it is coordinating with exchanges and bridge operators to blacklist the attacker’s address and support recovery efforts, while it continues forensic analysis using archive data and execution traces.
Saga described the attack as a coordinated sequence involving contract deployments and cross-chain activity that ended in rapid liquidity withdrawals.

Reports on the incident also said the attacker bridged assets to Ethereum and converted proceeds into ETH via swaps.
Saga said the incident affected the SagaEVM chainlet along with Colt and Mustang, but it did not affect the Saga SSC mainnet, the protocol’s consensus, validator security, or other Saga chainlets. It also said it found no evidence of validator compromise, signer key leakage, or consensus failure.
Saga has paused its SagaEVM chain following a smart contract exploit that resulted in the loss of approximately $7 million in bridged assets. Saga has halted its SagaEVM chain after bridged assets were lost due to a smart contract exploit.…
Websites that authenticate users through links and codes sent in text messages are imperiling the privacy of millions of people, leaving them vulnerable to scams, identity theft, and other crimes, recently published research has found.
The links are sent to people seeking a range of services, including those offering insurance quotes, job listings, and referrals for pet sitters and tutors. To eliminate the hassle of collecting usernames and passwords—and for users to create and enter them—many such services instead require users to provide a cell phone number when signing up for an account. The services then send authentication links or passcodes by SMS when the users want to log in.
Easy to execute at scale
A paper published last week has found more than 700 endpoints delivering such texts on behalf of more than 175 services that put user security and privacy at risk. One practice that jeopardizes users is the use of links that are easily enumerated, meaning scammers can guess them by simply modifying the security token, which usually appears at the right of a URL. By incrementing or randomly guessing the token—for instance, by first changing 123 to 124 or ABC to ABD and so on—the researchers were able to access accounts belonging to other users. From there, the researchers could view personal details, such as partially completed insurance applications.
