10 Best Fitness Trackers 2026 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 WHOOP Peak is a fitness tracker designed for people who want detailed health insights beyond basic step counting. It offers continuous monitoring of key health metrics such as sleep quality, heart rate, blood oxygen levels, stress, and menstrual cycles, making it ideal for users interested in tracking overall wellness and recovery rather than just workouts. The device comes with a 12-month membership that includes personalized coaching and health recommendations to help users improve their habits over time.

The tracker boasts an impressive battery life lasting over two weeks on a single charge and supports wireless charging for convenience. It is waterproof, allowing you to wear it during swimming or in wet conditions. Compatibility with smartphones and tablets enables easy data syncing. The WHOOP Peak does not include built-in GPS, which may be a drawback for those seeking detailed route tracking for running or cycling without carrying a phone.

If your focus is on health monitoring, sleep analysis, and recovery guidance, the WHOOP Peak provides a comprehensive package supported by strong battery life and a robust app experience. However, users mainly interested in fitness metrics like pace and distance with direct GPS tracking may find this device less suited to their needs.

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.
