Choosing between Garmin and Fitbit? This guide covers everything you need to know.
Garmin and Fitbit are two premier fitness wearable brands, making it challenging to decide between them. But while they may seem similar on the surface, there are some significant differences.
This decision ultimately comes down to the type of data you want. Once you work that out, picking between the two becomes much more straightforward.
Garmin is a natural choice for those who want to track sports, with its features generally geared toward delivering tip-top accuracy in the outdoors and detailed training feedback. Compared to its rival, Garmin also has a broader range of watches and price points, which can be handy for those seeking a device to grow into.
Fitbit, meanwhile, has expanded beyond basic step tracking in the last few years. Yet, it remains the better choice for those more interested in their overall health and well-being than hardcore fitness enthusiasts. It features an intuitive app, numerous motivational tools, and is generally available at more affordable entry-level prices, making it the perfect brand for those just starting their fitness journey.
That’s the skinny. But there’s a lot more to cover, so, below, we’ve covered the key areas—hardware, features, apps, and fitness tracking—to help you understand how the two compare.

An overview of Fitbit smartwatches and fitness trackers
Fitbit has six main wearables – all with clear remits:
Versa and Sense smartwatches
The Versa 4 smartwatch and the Fitbit Sense 2 are the brand’s latest smartwatches, released in 2022. They’re also the last Fitbit smartwatches, with Google quietly confirming in 2024 that there won’t be any new models produced.
However, they are still available (for now) and are solid wearables to consider. Think of them as Fitbit trackers in a watch form factor rather than top smartwatches in their own right, since they don’t come close to offering the features of an Apple Watch or Google Pixel Watch.
The Versa 4 and Sense 2 look identical, but the latter offers serious health sensors such as ECG, skin temperature, and a specific EDA sensor that tracks stress. The Versa 4 still has SpO2, GPS, and heart rate monitoring, but is simpler and cheaper.
It should also be noted that all Fitbit devices will now scan for heart rate rhythm irregularities using the optical heart rate monitor, which means there’s less emphasis on ECG.
Google Pixel Watch 3 – the unofficial Fitbit
Google has incorporated Fitbit’s tracking into the new Pixel Watch 3 (and the previous generations).
This is a ‘proper’ smartwatch, with an AMOLED display and access to the Google Play Store’s third-party apps and the brand’s services, such as Wallet and Maps. It packs in all the sensors and analysis of the Sense 2 and is the true Fitbit smartwatch option.
The downside? It only has a day of battery life if you choose the 41mm version, though the bigger 45mm model offered at least double that in our testing (even with the always-on display enabled.
Charge, Luxe & Inspire trackers
These are the classic, wristband-style fitness tracker devices Fitbit is best known for.
The Fitbit Inspire 3 is its entry-level tracker. It’s brimming with features, including heart rate, SpO2, temperature sensor, and a color screen. It offers plenty of bang, for a sub-$100/£100 buck.
The most advanced is the Charge 6, the flagship fitness tracker. It brings all the features from the Sense 2 (GPS, ECG, stress tracking, skin temperature), puts it in a wristband form factor, and adds integrated Google services (Pay/Maps) over its predecessor.
Then there’s the aging Fitbit Luxe, a fitness tracker that’s a bit of a throwback to the Fitbit Alta with its slim, fashion-focused design and is the only Fitbit fitness tracker to include a color touchscreen display. It also features core fitness tracking features, a heart rate monitor, and a SpO2 sensor.
An overview of Garmin’s watches
Garmin has over 30 different sports watches, and the differences can be quite obscure. As you ascend in price, you get more sensors and more complex data and analysis. Its watches cover options designed for runners, swimmers, triathletes, and even outdoor adventurers.
Garmin Forerunner
These running and triathlon-focused watches range are available between around $150-$600 / £150-£600. As the prices rise, you get more features, insights into your sports, and longer battery life.
The entry-level Forerunner 165 (above) offers a solid display and is an ideal starting point for those new to tracking their runs. The upper mid-range Forerunner 265 and 570, as well as the flagship Forerunner 965 and 970 devices, are watches designed for more advanced runners and triathletes seeking detailed sports science and recovery data.
Garmin Fenix
The Fenix family is Garmin’s all-action sports and outdoor watches. They have all the features and metrics imaginable but cost top dollar. The Fenix 8 is the latest generation, available in AMOLED or Solar editions, in multiple case sizes, and with various upgrades on offer materials and watch bands.
The price, as we say, is whopping. So, if you want a cheaper alternative, the last-gen Fenix 7 Pro and Epix Pro (Gen 2) still boast the brand’s latest HR sensor and solar/flashlight features across every model.
Garmin’s smartwatch lines
The company’s mid-range smartwatch, the Garmin Venu 3 (below), is a fantastic option that was only superseded in 2025 by the Venu X1. It features a sleek design, an impressive screen, and excellent tracking accuracy and wellness insights.
Meanwhile, the Vivoactive 6 is a pared-down version of the Venu, offering numerous trackable sports and smartwatch features, as well as good battery life. However, its tracking lacks the detail of pricier models. The design, screen, and heart rate technology aren’t as good as those of the Venu 3, but the features are mostly the same.
The Vivomove is a hybrid smartwatch with analog hands but fitness tracking in the background, though devices in this range haven’t been updated in many years. There’s also the Garmin Lily 2 and Lily 2 Active, the company’s 34mm fitness watches aimed at women.
Garmin fitness trackers and specialist watches
The Vivosmart 5 is the company’s latest fitness tracker. It features a slightly larger screen and tracks all the main Garmin health and wellness metrics, including sleep, stress, blood oxygen, and energy levels. However, there’s no built-in GPS.
Then there’s a myriad of others: Approach golf watches, Instinct outdoors watches, and many other spin-offs of the Fenix range.
Fitness and wellness tracking
Garmin’s fitness tracking is excellent, with steps, sleep, and activity minutes all logged by its devices. But in the last year, its wellness tracking has soared, too.
It has brought Body Battery energy tracking across its range, with newer devices (Venu 3/Vivoactive 6/Forerunner 975/570/165) all getting a vastly improved version of Body Battery. It will also track your heart rate 24/7, just like Fitbit.
Heart rate variability is also a focus, with the HRV Status now an ever-present among its range. Training Readiness is a top feature that indicates how well-prepared your body is for training, but it’s only available on high-end devices.
Of course, fitness tracking is Fitbit’s bread and butter. Updates to the Health Metrics dashboard, now open to non-premium users, make the Fitbit ecosystem even more interesting, regardless of your fitness level. The dashboard displays your resting heart rate, body temperature, SpO2, and HRV, along with how they compare to your baseline from the previous night’s sleep. If you have a Pixel Watch, you can also enjoy features like Cardio Load.
It’s a great touchpoint for wellness and a true indicator if you’re sick, overtired, or ready to perform. Garmin doesn’t have anything nearly as wellness-focused, though it does have an equivalent – Training Readiness – on some pricier models.
Fitbit is still our preferred ecosystem to track your general activity levels, but the gap is narrower than ever.
Winner: Fitbit
Heart health
In terms of general wellness, we think Fitbit has the edge here thanks to the simplicity of the data and the way resting heart rate is presented – although you won’t miss out on any data if you choose Garmin.
The Fitbit Sense 2 and Charge 6 now have an ECG sensor that offers medical-grade reading. It also packs a temperature sensor and provides additional insights to make it a potentially valuable health monitoring device.
Fitbit has also added a new continuous Afib detection feature that will scan your heart rate for signs of atrial fibrillation and alert you if you need to get checked out without the new to-spot check. That’s going to most devices across its range, even the entry-level Inspire 3.
Certain premium Garmin watches offer ECG if you live in the right region, but it’s not a feature that’s as well integrated as Fitbit.
However, Garmin has the upper hand (by some distance) when tracking heart rate during exercise, as we’ll detail more below. More emphasis is placed on accuracy, heart rate zones, and VO2 max – while more advanced data spins this into training effect, load, stress, and recovery data.
Winner: Fitbit (for general wellness features)
Sleep tracking
Fitbit certainly has the edge when it comes to nightly tracking. Fitbit’s sleep tracking accuracy is one of the most reliable and is much more than just a record of how well/badly you slept.
Users can also see oxygen variation (which could reveal sleep apnea symptoms), and the excellent Health Metrics dashboard is populated by nighttime biometrics.
Garmin used to lag badly in sleep tracking, but it has caught up somewhat. It will show light, deep, and REM sleep, as well as factors in respiration rate and skin temperature (depending on the device). Most watches will let you track blood oxygen at night, too, and Garmin has also added nap tracking in recent models.
Our testing has found Garmin’s tracking slightly generous in calculating sleep duration and less sensitive to wakeups. We’d say Fitbit still has the edge when it comes to sleep.
Winner: Fitbit
Stress and recovery
What’s also interesting to note is the approach of the two companies to stress tracking.
Fitbit uses Relax, which leverages the onboard heart rate monitor, along with HRV monitoring, to detect changes in heart rate and provide personalized breathing options.
The Stress Management Score is also offered across its devices, offering a single score generated from resting heart rate, sleep, and activity logged.
Fitbit’s Sense 2, Charge 6, and the Google Pixel Watch 2/3 up the ante with an EDA sensor and scan app that can detect electrodermal activity, which may indicate your body’s response to stress. It will also flag any instances of high stress that you can tag – and long-term use may reveal trends about stressful triggers. However, we do question how useful and user-friendly this is.
Garmin’s stress tracking is available on every current smartwatch and tracker. It’s less intrusive, is a simple stress score in any given moment, and shows physiological stress across the day. However, the data isn’t meaningfully presented and becomes another score out of 100. We found the data relatively meaningless.
Fitbit has jumped ahead again with the Daily Readiness Score (Premium only), which melds workouts, daily activity, sleep, and heart rate data to tell you how rested you are and how ready you are for another workout. It will even go further and suggest workouts suited to your physiological state.
Garmin has also aped this with Training Readiness, which does much the same thing. This score is only presented on its top-tier watches, such as Fenix/Forerunner. Some watches also have HRV Status, which checks if the biometric is affected by overtraining. It requires a considerable amount of user knowledge to interpret, though.
Winner: Fitbit
Female health tracking
Garmin and Fitbit offer female health tracking features, allowing users to log cramps and headaches. Fitbit uses that data to analyze your menstrual cycle and can predict when the next one will occur.
Garmin allows users to track their cycle, log symptoms, receive cycle predictions and fertile window notifications, and gain educational insights through their Garmin Connect app. It will also track daily physical and emotional symptoms to pay closer attention to fluctuations in sleep, mood, appetite, and athletic performance.
Garmin has also launched a pregnancy mode, which adds context to the physiological changes your wearable will record.
Winner: Garmin
Sports tracking compared
As you may have already gathered, those with ambitions to track a broader range of activities and receive deeper insights should consider Garmin. But how big is the gap between the two groups when tracking various sports?
GPS tracked workouts
Garmin has always been the king of GPS, but the feature is no longer exclusive to its devices.
Fitbit’s Versa 4, Sense 2, and Charge 6 fitness bands all have GPS – and Fitbit has been busy adding the feature over the past few years. However, we have found accuracy issues with the Fitbit Charge 5 and Charge 6.
The post-workout feedback aid is more basic, and the Fitbit app isn’t the best place to absorb your performance. It will connect to Strava, at least, so you can view activities there.
Almost every Garmin device has GPS – except lifestyle devices such as the Vivomove 3, Vivosmart 5, and Garmin Lily 2.
In addition, some of its devices feature GPS-based sports profiles, such as hiking, trail running, open water swimming, ultrarunning, and triathlon.
If you push into the upper echelons of Garmin’s range, you can adjust the accuracy and frequency of GPS activities to get up to 70 hours of tracking. Garmin Connect is geared toward evaluating your workouts—this is its strongest feature.
Winner: Garmin
Swimming
The Fitbit Charge 6, Inspire 3, Luxe, and Versa are all set for the pool, and the devices can be calibrated to specific pool lengths. However, the data is more basic, and there are no open-water options.
Garmin’s entire range is water resistant, and even basic running watches have pool swimming capabilities. If you’re into pool sessions, Garmin tends to be more reliable accuracy-wise for longer sessions, more metrics, and swimming-focused features.
Winner: Garmin
Heart rate in workouts
Heart rate is a staple of both sets of devices, but there’s no arguing with Garmin in sports tracking.
Both Fitbit and Garmin track your heart rate through sessions, offering information on your zone and improvements over resting heart rate—an indicator of improving fitness. Score draw here.
Fitbit and Garmin devices will also track VO2 max, called Cardio Fitness Score in Fitbit devices – although our testing found it to be a little high. Advantage Garmin. However, you will get more data with the Garmin mid-range Forerunners (or Fenix).
That VO2 max score will feed into things like Training Effect and race predictors, a step above for those training for half and full marathons.
All Garmin watches let you hook up a chest strap, which is not an option on Fitbit trackers. That lends to more accurate data and improved latency, especially during HIIT sessions.
Top-end Garmin’s can also adapt your heart rate zones by using your Lactate Threshold scores determined from fitness tests with a chest strap – a level of detail beyond most users’ needs, and also Fitbit’s skill set.
Winner: Garmin
Fitbit app for iOS and Android
Fitbit still offers one of the more rounded and easy-to-use fitness platforms.
This is particularly the case for beginners, who can dive into trends, dedicated workouts, sleep tracking, and social aspects, such as linking with friends and challenges.
The app is much more pleasing, easy to digest your stats, and given a redesign in 2023.
Some features are still behind the Fitbit Premium paywall, such as the wealth of fitness workouts and guided breathing content. That’s something that Garmin can’t match.
However, Health Metrics – the feature that shows deeper health stats such as heart rate variability, blood oxygen, temperature, resting heart rate, and breathing rate in one place – is now available to all Fitbit users. This data can show if you’re getting sick or under the weather.
Many third-party apps will shake hands with Fitbit, allowing you to pass data for workouts, calories, and other information. Strava is a good example of this, letting you feed your runs into your daily Fitbit stats, while any Fitbit activities will also show in the Strava app.
However, under Google’s ownership, the company has been stripping Fitbit smartwatches of their smartest features, including music playback and app integrations. It seems Google sees that as a threat to its Pixel Watch, which features Fitbit tracking built in.
Garmin Connect app
Garmin Connect is the home for your data. It’s rich with graphs and stats but not as easy to digest. It’s undoubtedly one for athletes and purists. In early 2025, the brand also introduced a Connect+ tier for those seeking additional insights.
Garmin has a Coach feature that offers workout suggestions for various goals. You can follow these live on almost all of its sports watches. The workouts will adapt to your training load and fitness and can be turned off if you don’t want them.
Then there’s the Connect IQ, the store for you to pick up (basic) apps, new watch faces, and new data fields for sports tracking. As with Fitbit, we’ve dived deep into how to run better with Garmin Connect and a Garmin Connect IQ app store guide.
The companion app, compatible with all Garmin devices and available on desktop, allows you to plan, track, and review your workouts. It’s not a great place to visualize wellness data, but Garmin Connect is far better for workout analysis, as you might expect.
Verdict: Garmin or Fitbit?
Why choose Fitbit?
Fitbit’s Versa 4 and Sense 2 are weaker than Garmin’s hardware. That means you should consider the Inspire 3, Charge 6, or Pixel Watch 3.
For classic-style activity bands, Fitbit remains king. However, even in this area, we have reservations about the accuracy of tracking features compared to Garmin. The truth is that fitness trackers aren’t a priority for many brands in 2025, which means the quality and competition are relatively weak compared to watches, rings, and other form factors.
Yet, we have no qualms about recommending the Pixel Watch 3—it’s an outstanding smartwatch with apps, payments, cellular support, and excellent build quality. The battery life on the 45mm model is also particularly impressive, reaching two or three days.
With Fitbit, you receive a 24/7 lifestyle option that can weave between the different aspects of your daily life. Chances are, if you’re looking to dip into this area, you’re more focused on health and wellness than personal bests.
The Health Metrics Dashboard is a great daily wellness companion, and the company’s excellent sleep tracking (and sleep apnea and atrial fibrillation detection) makes for a solid experience.
While Fitbit is diminishing as a hardware brand under Google’s ownership, it still offers excellent health and wellness features. However, Garmin has hugely closed the gap.
Why choose Garmin?
Choosing a Garmin watch over one from Google/Fitbit is the right decision if you’re looking for a device primarily for workout tracking.
Almost all the brand’s devices excel in outdoor tracking accuracy and advanced metrics. Plus, there are tons more designs and price points to work from. And virtually all modern Garmin watches score highly in our independent reviews, meaning you don’t have to be as selective as with Fitbit.
Garmin is also constantly improving in some of its traditionally non-priority areas—sleep, health, and innovative features. The strength of these subsections varies dramatically depending on the watch you select, but the general standard is as close to Fitbit in 2025 as ever.
Overall, Garmin’s UI and app experience aren’t as friendly for beginners—and there’s less emphasis on general well-being. However, if you want a device you can begin a running/cycling journey with and grow into the analysis over a few years, it’s the best brand to consider.
