In 2025, you might wonder if Fitbit is still relevant. Despite getting acquired by Google, Fitbit remains one of the most recognizable names in the industry. Fitbit trackers aren’t meant for the most hardcore of athletes, but they’re still excellent devices for tracking overall activity as well as monitoring certain health and wellness metrics like EKGs and blood oxygen levels.
That said, this is a transitional period from the Fitbit of old to whatever Fitbit will be in the future. 2023, in particular, was a messy year. There were multiple Fitbit server outages, and I wasn’t impressed with the decision to sunset legacy community features like challenges or the fact that all Fitbit accounts will soon require you to log in via Google. Speaking of which, the Fitbit-to-Google account migration started in 2023 and is required if you buy newer products like the Fitbit Charge 6 or Google Pixel Watch 3. The Fitbit app also got a new, more Google-like makeover, which didn’t go over well with many users. (Google has since made adjustments based on feedback.) And in 2024, much of Fitbit’s leadership, including co-founders James Park and Eric Friedman, left the company as roughly a thousand Google employees were laid off.
What I’m looking for
Fitness trackers allow you to track your health and activity. We conduct a mix of real-life testing, including napping and sleeping with them, taking them out on runs, walks, and hikes, and working out at the gym. We also evaluate how easy fitness trackers pair with iPhones and Android devices, their durability, accuracy, battery life, and performance. In cases where we test models designed for children, we test them on our own children and incorporate their feedback.
Fitbits tend to have longer battery life than more advanced smartwatches. Most are estimated to last around five days, but we’ve found that some features like an always-on display can drastically impact the time between charges. So I’m looking to see what you can realistically expect with “average” use.
Most Fitbits share the same basic feature set like steps, timers, and notifications. However, not every model is capable of EKG or real-time stress tracking. The same goes for built-in GPS. Does the feature set make sense given the price? Is it missing something that it shouldn’t be?
Fitbit has often been a more affordable alternative to smartwatches, but this space has changed quite a bit in the last few years. There are more options than ever, so does this device offer good value?
This encompasses a lot, but especially in terms of the overall form factor. If it’s for a casual user, is the design versatile enough for a variety of occasions? If it’s aimed at kids or athletes, are the straps durable enough?
You can look at how Google has handled the Nest acquisition as a road map to how things are going. The Googlefication of Fitbit will continue, but there are reasons to stick with its trackers in the meantime. Fitbit trackers are relatively affordable, especially since they often go on sale. All the devices also come with a free trial to Fitbit Premium, the company’s subscription service that adds guided workouts, meditations, and access to more in-depth metrics. So far, it appears Google takes its Pixel Watch lineup seriously, too. With the Pixel Watch 2, the company expanded extended warranty access and improved replacement options. You just have to go in with eyes wide open.

$350
The Good
- We finally get a bigger size!
- Moderate battery improvements
- Lots of neat Google integrations
- Good running updates
- Readiness and Cardio Load scores not locked behind paywall
The Bad
- It’s best with a Pixel phone
- Loss of Pulse detection is Europe-only for now
The existence of the Pixel Watch, now in its third generation, has thrown a wrench into Fitbit’s smartwatch lineup. Technically, it’s a Google product, but Google owns Fitbit, so they’re all Google products now. Fitbit powers all of the Pixel Watch’s health and fitness features. But really, this is the smartwatch that Fitbit never could manage to build on its own.
The Pixel Watch 3 is a significant update over its predecessors. It finally feels like Google’s no longer playing catch-up to its rivals. This year, the screens are brighter, the bezels are smaller, and there’s now a 45mm size for larger wrists. The larger size doesn’t look chunky, either. Internally, the processor and health sensors are the same as last year, though the third-gen device has an ultra wideband chip that allows you to unlock Pixel phones and some BMW car models.
It’s got the same beautiful design with a circular domed display that looks way more elegant than the squircle Versa or Sense smartwatches ever did. On your wrist, it looks like a watch, not a tracker dressed up as one. The display is a bit fragile for our taste, but as 2023, you can get a Preferred Care extended warranty in the US and Canada. This is one reason we recommend the Pixel Watch 3 over the original since at least you have a more affordable fallback should something happen to your display. Google also announced an option where you can skip customer support and mail in broken, out-of-warranty Pixel Watch devices for discounted replacements.
As for fitness features, the Pixel Watch 3 is much better for runners than it used to be. It includes a new running dashboard, advanced form analytics, custom running workouts, and even AI-generated workout suggestions. It’s also introduced a new metric called Cardio Load, which measures the intensity of your workouts and suggests a target based on your fitness goals. It’s conceptually similar to Garmin’s Training Load. The Daily Readiness Score has also been revamped and is no longer locked behind the Fitbit Premium paywall. On the health front, European users now have Loss of Pulse. If the watch detects you’ve lost your pulse, it’ll call emergency services on your behalf. The feature isn’t available yet in the US, though, as FDA clearance is still pending.
Additionally, Google has strengthened the watch’s integrations with its own services as well as other Pixel devices. For instance, you have offline Google Maps and a Google Home Tile. You can view your Nest Doorbell camera feed or control your Google TV from your wrist, and there’s also the option to record audio with the Recorder app and transfer it to your phone. With Call Assist, you can use your watch to tell anyone calling you need an extra second to pick up the phone.
If all you want is a fitness tracker that looks like a smartwatch, you can consider the $229 Versa 4 since it’s the more budget-friendly option. But there’s no real point in the Sense 2 since the Pixel Watch 3 can do all the same things — and more.

$80
The Good
- Good entry-level fitness & sleep tracker
- Bright OLED display
- Lightweight
The Bad
- Huge bezels
- Limited features compared to cheaper Amazfit Band 7
The Inspire line hasn’t always felt, well, inspired. But the $99.95 Inspire 3 is different. With a color OLED display, it’s reminiscent of the Fitbit Luxe of 2021, only with a matte black plastic case instead of a metal one. It’s a great throwback to classic Fitbits for people who only want the basics.
The Inspire 3 doesn’t overcomplicate things. It’s a fitness band. You won’t get built-in GPS, contactless payments, or digital assistants. Still, what it lacks in smarts it makes up for with Fitbit’s advanced sleep tracking, stress management features, and irregular heart rate notifications. The OLED display is also a step up from the Inspire 2’s monochrome screen, and you still get 10 days of battery life. (Though it’s more like two to three if you enable the always-on display.)

The Inspire 3 has a variety of accessories, including a clip attachment if you want to track steps discreetly. There’s even a gold or silver mesh strap if you want to dress it up a bit.
To be honest, the Inspire 3 and Luxe are quite similar, and they’re often around the same price. It’ll boil down to whether you think the Luxe’s nicer case is worth trading half the battery life for — the Luxe gets an estimated five days instead of 10.

Best Fitbit fitness tracker


$110
The Good
- Solid fitness and health tracking feature set
- It’s $20 cheaper!
- Adds more apps
- Can broadcast HR to fitness equipment
- The haptic button is better than the groove
The Bad
- YouTube Music is the only option and that’s $11 monthly
- The Fitbit-Google transition is a lil bumpy
- It’s not a physical side button
The Charge series has always been popular, and the $159.95 Charge 6 is no exception. It’s Fitbit’s higher-end fitness band but easily competes with the more expensive Versa 4 on features. It features a color OLED screen plus an EKG and EDA sensor. You also get built-in GPS, NFC payments, and SpO2 sensors — the only thing you’re really missing is a digital assistant.
The only qualm we have with the Charge 6 is the always-on display. While it’s beautiful, it’s a major battery drain. The Charge 6 has an estimated seven days of battery life, but that dwindles down to about two if you have the always-on display enabled. This is the same issue that we had with the Charge 5, but it’s fairly typical for Fitbit trackers these days.
Altogether, though, you’re getting a hell of a lot for the price. It’s the only FDA-cleared EKG wearable you can find for under $200, and the only other Fitbits capable of EKG and EDA readings are the Sense, Sense 2, and the Pixel Watch 2. So unless you’re dead set on the smartwatch form factor, the Charge 6 is the better overall deal.

Compared to its predecessor, the Charge 6 also adds an improved heart rate algorithm, Bluetooth compatibility with some gym equipment, and a few apps — namely Google Maps, Google Wallet, and YouTube Music. While YouTube Music works well, I’m not stoked that it requires an additional $11 monthly subscription. That said, it’s better than nothing, as Fitbit discontinued onboard music a while back.
In terms of hardware, the Charge 6 also features a haptic button instead of an inductive groove. It’s not a physical button, which is a little disappointing, but it’s more reliable thus far than the inductive groove, so I would count this as a net positive.
You could technically get the Charge 5 at a discount. However, I’d only do that if it’s significantly cheaper and price is your main consideration. The haptic button, while not what I wanted, is far better than the inductive groove and you have more app options. Turn-by-turn navigation is also handy for walks, and it at least offers some form of music playback.

$140
The Good
- Great build quality for a kids’ watch
- Cross platform
- Fun games that require physical activity to unlock
- Voice calls and text messaging with preselected contacts
- Family group chat
The Bad
- You’ll have to charge it every night
- Only two color options (but multiple band options)
The $179.99 Fitbit Ace LTE isn’t really a traditional fitness tracker, though it does track active minutes. Instead, it’s a smartwatch with a mix of kid-friendly games and activities and thoughtful, family-oriented communication features. It’s a walled garden, but an adorable one.
Instead of rigorously tracking health stats, the Ace LTE tracks “active minutes,” which fill a cute progress meter called a Noodle that runs around the face of the watch. Active minutes earn time with the Ace LTE’s built-in games that, combined with activities, unlock customizations for your kid’s avatar (called an Eejie) that lives in the watch, as well as its little house. You can also unlock different games and virtual items by connecting different watch straps.
With a $10/month subscription, you get real-time location tracking and both voice and text messaging to preselected contacts through the Fitbit Ace app (rather than the standard messaging and phone apps). As of November 2024, that includes other family members with Ace LTE watches, as well as a family group chat between parents and kids.

I like that the Ace LTE is built more like a cross-platform smartwatch for adults than other kid watches we’ve used, like the plasticky Garmin Bounce. It uses the same charger as the Pixel Watch 3, and gets about a day’s worth of battery on a charge. My kids enjoy it but aren’t obsessed with it — though they have been known to run laps up and down the hallway to earn more game time.
Google says the Ace LTE is best suited for kids aged 7 to 11, and that sounds right. My oldest is 10 now, and she’s been using an Ace LTE for about a year. Once she hits middle school, I think she’ll be frustrated that she can’t use it to talk to her friends. But for now it’s great. We recently got one for our 8-year-old, and it’s wild that they can text each other from their watches. It also means my 8-year-old can spam the group chat with emoji, but that’s fine too.

Should you even buy a Fitbit right now?
Fitbit officially became part of Google in 2021. Nothing changed overnight, but technically, it’s Fitbit by Google now. The Fitbit-to-Google migration started in earnest in the summer of 2023, and new users will be asked to log into Fitbit using their Google accounts. In 2025, this will be mandatory for everyone. In February 2023, Google angered longtime Fitbit users by shuttering longtime social features like Challenges and removing step streaks. (Step streaks have since been added back and expanded to Android.) Meanwhile, the Versa 4 and Sense 2 weren’t as feature-rich at launch compared to their predecessors, leading some to feel that Google purposefully did this to put the spotlight on its Pixel Watch. There were also multiple major server outages in 2023.
There’s some tension here and the future of Fitbit hardware is murky. Especially given the fact that Google laid off about a thousand employees from its hardware departments spanning Pixel, Fitbit, and Nest. If you’re buying a tracker for the first time and want it to last you a while, it might make more sense to opt for a Garmin or Amazfit tracker. Similarly, if you’re looking to upgrade to an older Versa or Sense smartwatch, you might want to see where the dust settles. However, if you know you want a Fitbit, then go ahead. If you’re not in a rush or are undecided, now is not a bad time to sit back and observe.
Update, July 7th: Added Fitbit Ace LTE as best Fitbit for kids, replacing Fitbit Ace 3. Adjusted pricing and availability.

![Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica
The East Antarctic Ice Sheet is almost unfathomably huge. Covering about 75% of the entire frigid continent (nearly everything on its side of the Transantarctic Mountains), the sheet covers about 3.9 million square miles (10.2 million square kilometers) and extends down 1.4 miles (2.2 km), on average, before coming into contact with Earth’s surface. At its deepest, the ice plunges down over 3 miles (4.9 km). For decades, scientists assumed that this literally continent-sized block of ice rested on an expansive and stable chunk of Earth’s crust known as a craton. A team of researchers has now complicated that picture—mapping a vast, interconnected geological structure that fans out from a troubling “tectonic deformation.” Beneath this ice sheet, thinner and more geologically recent slices of crusty lithosphere fan out into hidden valleys called “pull-apart basins.” These basins—30 elongated wedge-shaped valleys in total—constitute an entirely new, continental-scale geological region underneath Antarctica, in fact, one which the researchers have named the East Antarctic Fan-Shaped Basin Province (EAFBP). But it’s how they likely formed that has now caught researchers’ attention.
To put it bluntly, it turns out that about 90% of the planet’s fresh water ice may not be on solid ground. Geologist John Goodge called the team’s findings “provocative” in an independent commentary on the new study, published Thursday in the journal Nature Geoscience.
“East Antarctica is typically considered from seismic tomography and geodetics to be ancient and generally stable,” according to Goodge, who studies continental tectonics with the nonprofit Planetary Science Institute. “[But] something else is going on at depth.” Continental divides Goodge speculates that this seemingly “coherent pull-apart system,” as presented in the new study, might help explain a variety of mysterious heat and water flows beneath this ice sheet’s surface, like that enormous subglacial lake identified in 2016 or some of the hundreds more like it.
The study’s authors, led by geophysicist Egidio Armadillo at the University of Genoa in Italy, agreed: “Because these basins underlie about half of the East Antarctic Ice Sheet, they are likely to heavily influence both ice-flow and landscape evolution,” the researchers wrote in their study, also published Thursday in Nature Geoscience. Armadillo’s team, coordinating across Europe and the U.K., developed their new understanding of Antarctica’s hidden bedrock via an exhaustive set of sensory data. Gravitational and magnetic anomalies were mapped via low-altitude airborne surveys. Ground surface features were mapped with seismic tools, using sound waves that vibrate through the ice and ping back information about subglacial landscapes in 3D. The grey, magenta, and cyan lines represent the apparent new fault lines discovered. Credit: Nature Geoscience All of this data—the fruits of “multi-national efforts to image within and below the ice sheet,” as Goodge put it—had already revealed that regions of the continent were “undergoing more rapid movement and ice-mass loss than previously recognized.” Armadillo’s team merely helped to explain why.
The mechanism Armadillo and his colleagues proposed for the formation of these fan-shaped basins is called “distributed rotational extension.” It involves points called Euler poles around which tectonic plates pivot or rotate rather than smash into each other or pull apart. The result is a bit like decks of cards being spread out on a table, thinning out the stack of Earth’s crust as it moves. An icy situation Goodge took pains to spell out the basins’ implications for melting Antarctic ice due to climate change and the risk of rising global sea levels.
The mere existence of these basins, he wrote, “could introduce widespread, systemic instability to the East Antarctic Ice Sheet” via thinner layers of Earth’s crust and more heat flow from below. On top of that, a series of fault-line “troughs” documented between the basins appear “tailor-made to promote outward flow of ice streams from the interior” into the world’s oceans, he said. That said, the team’s findings are unlikely to end this debate. As Goodge noted, Antarctica is “the last continental frontier of scientific exploration.” It’s still a very mysterious place, one that’s challenging to study given its inhospitable temperatures and extreme geography. Its “cryptic subglacial geology” might stay that way for a while. #Scientists #ContinentSized #Geological #Structure #Hiding #Beneath #AntarcticaAntarctica,Geology,mapping,Plate tectonics Scientists Found a Continent-Sized Geological Structure Hiding Beneath Antarctica
