The best smartwatch for fitness in 2024 combines advanced health tracking, precise workout metrics, and all-day wearability. The Apple Watch Ultra 2 stands out as the top overall choice for fitness enthusiasts, offering the most comprehensive sensor suite, solid battery life, and seamless integration with iOS. However, the best choice depends on your specific needs—Garmin dominates for serious athletes, while Samsung and Fitbit offer excellent alternatives for Android users and those focused on wellness tracking.
Before diving into specific models, it’s worth understanding what separates a good fitness tracker from a great one. The core elements include accurate heart rate monitoring, GPS tracking, water resistance, and robust workout app ecosystems. Beyond these basics, newer smartwatches increasingly offer blood oxygen monitoring, ECG capabilities, skin temperature tracking, and sleep analysis.
Battery life remains a critical differentiator. Many fitness-focused users find that daily charging becomes tedious, especially when tracking multi-hour activities. This is where dedicated fitness watches like Garmin and Coros often outperform general-purpose smartwatches. The processing power and app ecosystem of Apple and Samsung watches bring convenience, but often at the cost of requiring more frequent charging.
Software support and update cycles matter too. A smartwatch is an investment you’ll likely keep for three to five years, so understanding which manufacturers commit to long-term software updates becomes essential for long-term value.
Apple’s second-generation Ultra represents the company’s most serious attempt at capturing the fitness market. Released in late 2023, the Ultra 2 builds on its predecessor with a brighter display, the new S9 SiP processor, and Apple’s familiar watchOS ecosystem.
The 49mm titanium case houses an array of sensors that rival dedicated medical devices. The optical heart rate sensor works alongside an electrical heart sensor for ECG, while blood oxygen monitoring provides peace of mind during intense workouts. The precision GPS tracks your routes with impressive accuracy, and the 36-hour battery life (extending to 72 in low-power mode) addresses one of the original Ultra’s few weaknesses.
What sets the Ultra 2 apart is its breadth. Whether you’re running, swimming, cycling, or hiking, the device handles it all with aplomb. The depth gauge and water temperature sensors make it suitable for scuba diving up to 40 meters. For triathletes, the multisport workout mode seamlessly transitions between disciplines.
The main consideration is ecosystem lock-in. The Ultra 2 works best with iPhones, and while it technically functions with Android, you lose significant functionality. The starting price of $799 also places it firmly in premium territory.
“The Apple Watch Ultra 2 represents a shift in philosophy for Apple—rather than a general-purpose smartwatch with fitness features, this feels like a fitness tool that happens to be a smartwatch.”
For many users, the Series 9 hits the sweet spot between capability and price. Released alongside the Ultra 2 in September 2023, the Series 9 introduces the Double Tap gesture, a faster processor, and a brighter display while maintaining the familiar 41mm and 45mm case sizes.
The health tracking capabilities match the Ultra 2 for everyday use. Heart rate monitoring, ECG, blood oxygen, and sleep tracking all work reliably. The Workout app provides extensive exercise type support, and Apple Fitness+ offers guided sessions if you want structured training.
Battery life remains the Series 9’s limitation. Expect roughly 18 hours of use between charges, though this improves with the new Low Power Mode that can extend to 36 hours. Heavy GPS workout tracking will drain the battery faster, meaning some users need to charge daily.
At $399 for the GPS model, the Series 9 costs significantly less than the Ultra 2 while delivering 90% of the fitness functionality for most users. If you don’t need the Ultra’s extended battery, dive computer features, or titanium construction, the Series 9 makes more financial sense.
Samsung’s 2023 flagship watches brought meaningful improvements in health tracking and processing power. The Galaxy Watch 6 introduced the BioActive sensor, which combines optical heart rate, electrical heart (ECG), and bioelectrical impedance analysis for body composition metrics.
The rotating bezel on the 6 Classic remains a distinctive feature that many users prefer for navigation and app interaction. The physical dial provides tactile feedback that touch-only interfaces can’t match, and it genuinely helps during workouts when your fingers might be sweaty.
GPS performance has improved substantially over previous generations. Route tracking feels accurate, and the workout detection works reasonably well for automatically starting exercise sessions. Samsung Health provides a comprehensive fitness ecosystem, though it doesn’t quite match the breadth of Apple’s Workout app for exercise variety.
Battery life varies significantly between usage patterns. A typical day with mixed use gets you through 24 hours, but heavy GPS tracking will have you reaching for the charger earlier. The faster charging speeds (10W versus previous generation’s 5W) help mitigate this somewhat.
One advantage Samsung holds is broader compatibility. While the best experience comes with Samsung phones, the Galaxy Watch 6 works reasonably well with any Android device, giving users more flexibility than Apple’s ecosystem-locked offerings.
Garmin has long dominated the serious fitness watch market, and the Forerunner 965 continues that tradition. This is a watch designed primarily for athletes rather than general consumers, and everything about it reflects that focus.
The 1.4-inch always-on AMOLED display is large and readable in direct sunlight. The titanium bezel keeps weight manageable at around 53 grams while adding durability. Battery life stretches to 23 days in smartwatch mode and 31 hours in GPS mode—numbers that put Apple and Samsung to shame.
The training readiness score analyzes your sleep, recovery, and recent workout intensity to tell you whether you’re ready for a hard session or should take it easy. This kind of analytics-focused approach appeals to athletes looking to optimize their training rather than simply track it.
GPS accuracy matches or exceeds any consumer smartwatch on the market. Garmin’s multi-band GPS technology provides exceptional positional accuracy, even in challenging environments like dense urban areas or covered trails.
The trade-off is general smartwatch features. Notifications work, but the user experience feels clunkier than Apple or Samsung. Music storage and payment capabilities exist but aren’t as polished. If you primarily want a smartwatch that happens to track fitness, look elsewhere. If you want a fitness tool that handles basic smartwatch tasks, the Forerunner 965 excels.
The Fenix 7 Pro represents Garmin’s flagship multisport watch, designed for adventurers who need exceptional durability alongside comprehensive training features. The solar-charging sapphire crystal display option adds practical functionality for extended expeditions.
Build quality exceeds anything from Apple or Samsung. The fiber-reinforced polymer case with metal rear cover survives impacts that would crack lesser watches. Water resistance to 10ATM means you can swim, surf, and snorkel without worry. This is a watch built to last years of serious abuse.
Training features overlap substantially with the Forerunner 965, including the training readiness score, performance metrics, and recovery suggestions. The Fenix adds topographic maps and multi-GNSS support that athletes venturing into remote areas will appreciate.
The price reflects this durability and feature set. The 7X Pro solar model commands $1,000, making it an investment. For most users, the Forerunner 965 provides similar fitness functionality in a lighter package at a lower price. The Fenix makes sense for mountaineers, ultra-marathoners, and anyone who needs maximum durability.
Fitbit’s approach to fitness tracking emphasizes holistic wellness rather than hardcore athletic metrics. The Sense 2, released in late 2022 with subsequent updates, continues that tradition while adding Google integration.
The stress management features stand out. Continuous cEDA (electrodermal activity) sensors detect potential stress events, and the daily readiness score helps you understand whether your body is prepared for exercise. Sleep tracking remains class-leading, with detailed breakdown of sleep stages and personalized recommendations.
Health sensors include ECG, blood oxygen, and skin temperature variation. The Amazon Alexa integration (or Google Assistant on the latest models) provides voice assistant capability that some users find valuable.
Battery life reaches about six days with typical use, falling to around three days with always-on display and heavy tracking. This still beats Apple and Samsung but falls short of Garmin’s endurance.
The Google acquisition has brought some uncertainty. Fitbit’s separate ecosystem increasingly merges with Google services, which raises questions about long-term data policies and feature roadmaps. Current owners report the experience remains solid, but the future direction warrants watching.
Not everyone needs premium pricing. Several options provide solid fitness tracking at more accessible price points.
The Amazfit GTR 4 offers impressive battery life (14 days), accurate GPS, and comprehensive health monitoring at roughly $200. The Zepp app provides data analysis, though it doesn’t quite match the polish of Apple Health or Samsung Health. For budget-conscious users who prioritize battery and basic fitness tracking, Amazfit delivers reasonable value.
Garmin’s own Venu 3 sits between the Forerunner and lifestyle-focused lines. It provides solid fitness tracking with better smartwatch features than the Forerunner, though at $449, it’s not quite budget-friendly.
The Apple Watch SE (2023) brings most Series 9 fitness features at $249, making it the most affordable Apple Watch option. You lose always-on display, blood oxygen, ECG, and temperature sensing, but core workout tracking remains solid.
Battery performance varies dramatically across these devices, often determining which watch fits your lifestyle.
Garmin leads decisively here. The Forerunner 965 and Fenix 7 Pro can go weeks without charging, transforming how you use a smartwatch. Long-distance runners and multi-day hikers rarely need to think about battery life.
The Apple Watch Ultra 2 improves dramatically over standard Apple Watch, achieving 36 hours in normal use and up to 72 hours in Low Power Mode. Most users will charge every two to three days rather than daily.
Samsung Galaxy Watch 6 manages a full day with moderate use but struggles with extended GPS workouts. If you marathon train regularly, keep the charger nearby.
The Fitbit Sense 2 lasts four to six days depending on features enabled, sitting comfortably in the middle ground.
Your smartphone operating system significantly impacts which smartwatch makes sense.
iPhone users have three strong options: Apple Watch Series 9 for most buyers, Apple Watch Ultra 2 for serious athletes, and potentially the Samsung Galaxy Watch 6 if you want variety (though integration is weaker). The Garmin ecosystem also works fine with iPhones.
Android users face a more interesting choice. Samsung Galaxy Watch 6 offers the tightest integration with Samsung phones, but works well with other Android devices. Garmin provides the best fitness experience regardless of phone platform. The Fitbit Sense 2 integrates with Google services, which may appeal or concern depending on your privacy preferences.
Windows and feature phone users should lean heavily toward Garmin. The Forerunner and Fenix lines operate largely independently of phone ecosystems, offering full functionality even when not paired.
The right fitness smartwatch depends entirely on your priorities.
Choose Apple Watch Ultra 2 if you want the most complete package—exceptional fitness tracking, beautiful design, and full smartwatch capabilities work together seamlessly. Budget around $800 and accept daily charging.
Choose Apple Watch Series 9 if you want nearly all the fitness features at a lower price. The $399 starting price makes this accessible, and the smaller case fits more wrists comfortably.
Choose Samsung Galaxy Watch 6 Classic if you prefer Android and value the rotating bezel and Samsung’s health sensors. The $399 price tag is competitive with Apple.
Choose Garmin Forerunner 965 if you’re a serious athlete prioritizing training analytics and battery life over smartwatch features. The $600 price is justified if you train multiple times weekly.
Choose Garmin Fenix 7 Pro if you need maximum durability and expedition features. The $600 to $1,000 investment makes sense for outdoor adventurers.
Choose Fitbit Sense 2 if holistic wellness tracking and sleep analysis matter more than athletic performance metrics. The stress management features are genuinely useful for busy professionals.
The fitness smartwatch market has matured significantly. Every option listed here provides capable workout tracking, reliable heart rate monitoring, and useful health insights. The differentiation comes in the details—battery life, ecosystem integration, software polish, and specific athletic features.
Rather than overthinking the choice, consider your primary use case. Runners should look at Garmin. iPhone users generally fare best with Apple Watch. Android enthusiasts have legitimate options in Samsung and Garmin. The “best” smartwatch is simply the one that fits your lifestyle and encourages you to stay active.
Expect continued improvement in health sensors, particularly for blood glucose monitoring, which several manufacturers are working toward. Battery technology advances will also gradually reduce the charging frequency burden that affects most current smartwatches.
