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.

![This former notorious red-light district is now one of the world’s top AI hubs | TechCrunch
What every U.K. AI startup wants to know these days is, how can I get office space in King’s Cross?
The area is so hot that a VC firm allegedly recently won a deal by promising a founder office space in the neighborhood. “We stop at nothing to win deals [for] and to support” founders, “including helping them source office space when needed,” the firm told me when asked about the rumor, declining to confirm or deny any details.
The neighborhood’s popularity began back in 2016 when DeepMind — then newly acquired by Google — moved in. Soon after, a flood of AI startups followed, wanting to be around the Google DeepMind magic. Today, they hope to take advantage of the cluster of AI talent there.
This has transformed King’s Cross into one of the world’s top AI hubs, rivaled only by San Francisco and Beijing. Around London, it’s known by the sobriquet “Knowledge Quarter,” as it’s home to names like OpenAI, Meta, Isomorphic Labs, Cusp AI, Wayne, Recursive, and, a little farther down the road, Synthesia and Anthropic. The European Technology Network (ETN) just moved into a glossy new office nearby, while University College London sits around the corner.
Mixed in with the new developments are trendy food spots like Hoppers and BAO. Hop a train from King’s Cross, and founders can be in Cambridge in 45 minutes to source talent or can be in Paris in two hours to strike a deal.
Who would have guessed that a little more than 20 years ago, this was one of the seediest areas in London?
“In the ’80s, crack and heroin made the area a major narcotics market,” Hussein Kanji, an investor at Hoxton Ventures, said, recalling syringes in tree trunks and gangs patrolling the streets. “In 1982, the local church was occupied by the English Collective of Prostitutes for 12 straight days.” Then, in the early 2000s, a real estate developer had a dream and, well, “now it is the AI hotbed of the United Kingdom,” Kanji said. “What a change.” Around 18 months ago, his portfolio company BioCorteX moved from the neighborhood Holborn to the Jellicoe building in King’s Cross, hoping to be near the action. “Lots going on in London right now,” Nik Sharma, co-founder of BioCorteX, told me. “Lots of hyperscalers moving in.” That includes, reportedly, Jeff Bezos’ AI company Prometheus, which is also said to be in talks to move into the Jellicoe.
There are around 3,600 AI startups in London, which, together, have raised around .1 billion out of the .8 billion raised in the city since late July, according to Dealroom. Since the start of June, AI-related startups have leased more than 1 million square feet of office space in London, according to the real estate firm Knight Frank. With that, prime rents in King’s Cross have risen 18% over the past three years, Chris Dunn, a commercial insight associate at the firm, told me. That percentage represents only the largest leases encompassing at least 10,000 square feet, like the ones OpenAI and Prometheus are signing. The shorter deals go for even more, he said, and now the vacancy rate for conventional office space is just 0.9%. “Demand has outstripped supply,” he continued.
Today, one of the big topics of the area is sovereignty. It was a wake-up call for many when Anthropic shut off access to Mythos and Fable this summer, leaving some in the ecosystem to conclude: “We’d better look after ourselves,” Saul Klein, co-founder of the VC firm Phoenix Court, told me.
Phoenix Court is located in the King’s Cross area and has three portfolio companies in the vicinity, including Olix (which just announced a .3 billion valuation), Early Health and CoMind. Robin Klein, co-founder of the firm, said the shutdown of Fable and Mythos access was a “small but sharp reminder that Europe can’t simply rent its AI capabilities and capacity; it needs to build and hold some of its own.” King’s Cross, he said, is where much of this building is actually happening.
“The bigger question,” he continued, “is whether the U.K. builds the infrastructure, compute, energy, capital, to make this self-reliance durable, rather than just hosting outposts of U.S. labs.”

Top founders want to stay
Simon Kohl, founder of Latent Labs, has offices in King’s Cross and San Francisco. The London office, at the moment, is growing faster, and he’s more bullish than ever on the ecosystem, he said. “The mood right now feels less like London trying to catch up and more like London becoming one of the default places to start a serious AI company,” he said. Look around and you are likely to see Wayve testing its autonomous cars. Founded in 2017 by co-founder Alex Kendall, the unicorn is one of London’s biggest success stories.
“Ten years ago, building a frontier AI company from London felt like an unusual choice,” Kendall told me. “Now it feels like an obvious one.” Wayve moved into King’s Cross in 2018 looking for a space that could double as a garage — “a rare combination in Central London,” Kendall said. He has watched the ecosystem mature around him — and it’s now evident that a startup can stay in London, raise serious capital, hire world-class AI talent, and remain globally competitive, he said. Down the street from Anthropic’s new 158,000-square-foot office is the AI agent builder Sierra and the AI video platform Synthesia.
Laura Gonzalez Florez, Synthesia’s chief of staff and head of people, says the company moved into its glossy new office building a year ago to accommodate its growing team. They were drawn to the area for the same reason as everyone else: “It’s very close to the airport … very close to where a lot of investors are,” she said.

Around two-thirds of Synthesia’s engineers are remote, Gonzalez Florez said, letting the company tap into an affordable, international, and diverse talent pool and helping it scale faster. “From London, we can hire and work, without any problem, people from anywhere, from Slovenia to Portugal,” she said.
Unsurprisingly, London’s AI boom is also causing a talent war.U.K. AI job postings have skyrocketed in the past few years, per data from PwC. When Anthropic announced it moved into town earlier this year, it listed, for example, a salary range of £260,000 to £630,000 for a machine learning research engineer when the average salary in London for the same role is around £102,000. Some founders in the U.K., like those in Silicon Valley, are being forced to raise more and bigger rounds to keep up.
“The real test is whether more globally significant AI companies are founded, funded, and scaled from the U.K., while continuing to attract the world’s best talent to build them here,” Zain Ali, founder of the King’s Cross-based AI legal firm Centuro, told me. “If that continues to happen, King’s Cross won’t just be an AI hub. It’ll become one of the U.K.’s most important strategic assets.”
