10 Best Fitness Trackers 2025 in the United States

The Apple Watch Series 11 GPS 46mm is a strong choice if you want a fitness tracker that goes beyond basic activity monitoring. It offers comprehensive health tracking, including detailed heart rate monitoring, ECG readings, blood oxygen levels, and even hypertension and sleep apnea notifications, which is quite advanced. The sleep tracking with a sleep score helps you understand and improve your rest. Its built-in GPS ensures accurate workout and location tracking, ideal for running or outdoor exercise. The watch is water resistant up to 50 meters and dust resistant, making it durable enough for swimming and everyday wear. The always-on, bright Retina OLED display is easy to read during workouts or day-to-day use.

Battery life delivers about 24 hours under typical use, covering a full day but meaning you’ll likely need to charge it nightly; however, fast charging helps if you’re in a hurry. Compatibility is designed primarily for iPhone users, so it works best if you already have an iPhone. The lightweight, thin design makes it comfortable to wear all day, including while sleeping for continuous tracking. Safety features like fall and crash detection add extra peace of mind.

This smartwatch suits those who want an extensive health and fitness tool combined with smart features and are invested in the Apple ecosystem. While battery life might be a limitation if you prefer longer use without daily charging, and the price point tends to be higher than simpler fitness bands, it offers significant value for users seeking advanced monitoring and seamless integration.

The Apple Watch SE 3 is a strong choice for those looking for a fitness tracker packed with useful health and safety features. It offers reliable activity and heart rate tracking, along with detailed sleep monitoring that includes sleep scores and apnea alerts, which is quite valuable for users wanting deeper insights into their health. The built-in GPS is accurate and helpful for tracking outdoor workouts without needing your phone. The always-on Retina display makes it easy to glance at your stats or the time without moving your wrist, which works well during exercise.

Battery life supports about 18 hours of typical use, which covers a full day, and it charges quickly—getting 8 hours of use from just 15 minutes of charging. While this is sufficient for daily workouts, heavy users who track activities overnight might need to charge daily. The watch is water resistant, suitable for swimming or sweaty workouts. It connects seamlessly with iPhones and offers extras like emergency fall detection and crash alerts, adding peace of mind.

A few things to consider: while the watch has many sensors, it might feel a bit complex for people not used to smart devices, and some advanced health features require an iPhone to unlock their full potential. Also, the 40mm size fits most wrists comfortably but may be small for larger wrists. This Apple Watch SE 3 fits well for fitness enthusiasts who want a smartwatch that tracks workouts, heart rate, and sleep effectively, provides smart notifications, and prioritizes safety features, especially if you already use an iPhone. It balances functionality with ease of use, though daily charging might be needed if you use all features extensively.

The Garmin Venu 4 is a solid choice if you're looking for a fitness tracker that feels more like a full-featured smartwatch. Its bright, colorful 1.4-inch round display is easy to read, and the stainless steel build adds a nice premium touch. It covers all the fitness essentials, including accurate heart rate monitoring, sleep tracking with personalized coaching, and built-in GPS for outdoor activities. You also get advanced health features like Body Battery energy levels and stress tracking, which help you understand how your body is doing throughout the day.

The device supports over 80 sports apps and offers daily workout suggestions and personalized training plans, making it great for users who want guided fitness support. Battery life is impressive, lasting up to 12 days, so you won’t need to charge it frequently. It also lets you make and take phone calls and respond to messages right from your wrist when paired with your smartphone. One standout is the built-in flashlight, a handy feature for low-light conditions.

The watch works well with both iPhone and Android devices. If you want a smartwatch that balances serious fitness tracking with useful everyday features and a long-lasting battery, the Garmin Venu 4 is worth considering.
