10 Best Fitness Tracker Smart Watches 2025 in the United States

The Apple Watch Series 10 (GPS, 46mm) is a strong choice if you're looking for a fitness tracker smartwatch that blends health insights with smart features. It offers precise heart rate monitoring, including ECG capabilities and alerts for unusual heart rhythms, which is excellent for people who want detailed heart health data. The built-in GPS is reliable for tracking outdoor activities like running, cycling, and swimming, and it includes extra sensors for water temperature and depth, making it suitable for swimming and other aquatic workouts.

Battery life is decent for everyday use, lasting about 18 hours, which means you’ll likely need to charge it daily, but the fast charging feature is helpful if you’re in a hurry. Its water resistance up to 50 meters and dust resistance make it durable for active lifestyles. The always-on Retina display is bright and large, providing clear visibility even outdoors, which many users will appreciate. Sleep tracking includes detection of sleep stages and signs of sleep apnea, offering useful wellness data beyond basic activity tracking. Compatibility is limited to iPhone XS or newer with iOS 18+, so it won’t work with Android devices or older iPhones, which is important to consider if you don’t use Apple products.

The watch also stands out with safety features like fall and crash detection, making it not just a fitness tracker but a helpful companion for emergencies. The 18-hour battery life means it’s not the best option if you want multi-day use without charging. Additionally, this model is on the pricier side, which might not fit all budgets, and it is designed primarily for Apple users, so compatibility with other phones is very limited. If you have an iPhone and want a comprehensive device that tracks your fitness accurately while offering advanced health and safety features, the Apple Watch Series 10 is a compelling pick. Its high-quality display, robust activity tracking, and smart connectivity features make it more than just a fitness tracker—it’s a versatile smartwatch for an active lifestyle.

The Apple Watch SE (2nd Gen) is a solid choice if you want a fitness tracker that also keeps you connected without needing your iPhone nearby, thanks to its cellular option. It includes built-in GPS, so you can accurately track outdoor workouts like running or cycling. The heart rate monitor is reliable and works alongside safety features like Fall and Crash Detection, giving extra peace of mind. Sleep tracking is included, helping you understand your rest patterns, though it’s not as detailed as some specialized sleep devices.

The battery life typically lasts a full day, which is enough for daily use but requires nightly charging. With a 50-meter water resistance, you can swim or shower worry-free. Compatibility is best if you already use Apple devices, as it integrates smoothly with the iPhone and Apple services. The display is bright and sharp with a 40mm screen, easy to read during workouts or daily use. Activity tracking covers various workouts with detailed metrics, and the included Apple Fitness+ subscription adds extra motivation.

While the battery might not satisfy those who want multi-day use without charging, and it’s not compatible with Android phones, this smartwatch is a fashionable and functional option for Apple users focused on fitness, safety, and staying connected on the go.

The Apple Watch Series 10 is a strong choice for anyone looking for a well-rounded fitness tracker and smartwatch. It offers advanced health features like ECG and blood oxygen monitoring, plus alerts for abnormal heart rates, which can help you stay on top of your health easily. Its built-in GPS is accurate and supports a wide variety of workouts including swimming and outdoor activities, thanks to 50-meter water resistance and additional sensors like depth and water temperature. The always-on Retina display is bright and clear, making it easy to check stats during exercise.

Battery life supports up to 18 hours of regular use and can recharge quickly, though you might still need to charge it daily if you use it heavily. It tracks sleep comprehensively, even detecting signs of sleep apnea, which is a bonus for those focused on rest quality. Compatibility is limited to iPhones (Xs or newer) running iOS 18 or later, so Android users won’t be able to use it. Safety features such as fall and crash detection add peace of mind during workouts and daily life.

The design is lightweight and comfortable, with many band options for personalization. This watch is a premium product with a higher price point, and features like cellular connectivity require an additional plan. If you want a stylish, highly capable fitness companion tightly integrated with Apple devices, this watch fits well. However, if you prefer longer battery life or use a non-Apple phone, other trackers might serve you better.
