10 Best Fitness Tracker For Iphones 2025 in the United States

The Fitbit Inspire 3 offers impressive compatibility with iPhones through Bluetooth connectivity, ensuring seamless integration with your device. Its standout feature is the comprehensive health monitoring, including 24/7 heart rate tracking, stress management, and sleep tracking, making it a valuable tool for those keen on maintaining their well-being. The addition of a Daily Readiness Score and personalized Sleep Profiles further enhances its usability for fitness enthusiasts.

With GPS tracking available via smartphone, it efficiently supports outdoor activities, although it lacks built-in GPS which might be a downside for serious runners or cyclists who prefer leaving their phone behind. The battery life is commendable, lasting up to 10 days, reducing the hassle of frequent charging. The tracker is also water-resistant up to 50 meters, adding durability and making it suitable for swimming or showering.

However, the small screen size (0.76 inches) may limit ease of use for those who prefer larger displays, and its lightweight design (3.8 ounces) ensures comfort during extended wear. Smartphone notifications, including calls and texts, keep you connected on the go. The included Premium membership offers advanced analytics and insights but requires activation within 60 days of device activation. The Fitbit Inspire 3 is thus ideal for users looking for a reliable and feature-rich fitness tracker that integrates well with iPhones, though those requiring built-in GPS might need to consider other options.

The Garmin vívoactive 5 is a solid fitness tracker, particularly compatible with iPhones and Android devices. It boasts an impressive battery life of up to 11 days in smartwatch mode, which means less frequent charging and more time tracking your activities. The bright and colorful AMOLED display makes the data easy to read and engaging. The device offers comprehensive health monitoring, including wrist-based heart rate, Body Battery energy monitoring, sleep tracking with personalized coaching, and stress tracking.

Additionally, it features advanced training options and more than 30 built-in sports apps, covering a wide range of activities including running, swimming, and even wheelchair-specific workouts. The built-in GPS is a great feature for outdoor activities, providing accurate location tracking without needing to carry your phone. Water resistance ensures you can use it while swimming or in the shower without worry. For music lovers, the ability to download playlists and listen phone-free is a convenient feature.

However, some weaknesses include a relatively small screen size at 1.2 inches, which might be less appealing for users who prefer larger displays. Additionally, while it offers extensive functionalities, the vast array of features might be overwhelming for users who prefer simpler, more straightforward devices. Finally, the need to manage another app (Garmin Connect) might be seen as a minor inconvenience for some users. Despite these minor drawbacks, the vívoactive 5 is a strong contender in the fitness tracker market, especially for users looking for a detailed health monitor with robust sports tracking capabilities.

The Garmin Forerunner 55 is a solid choice for iPhone users who want a straightforward fitness tracker with strong running and activity features. It pairs easily with iPhones via Bluetooth and offers up to two weeks of battery life in smartwatch mode, which means less frequent charging. The built-in GPS accurately tracks your runs without needing your phone, and the wrist-based heart rate monitor provides continuous heart rate data, although it’s not a medical device. It supports a variety of activities beyond running, like swimming and cycling, making it versatile for fitness enthusiasts.

The display is clear and easy to read, and the watch delivers useful smartphone notifications to keep you connected. Helpful training tools like suggested workouts, PacePro for pacing, and race time predictions can guide you to improve, which is great if you’re serious about your running goals. Water resistance means you can wear it while swimming or in the rain without worry. Sleep and stress tracking add valuable health insights.

The screen is on the smaller side at just over an inch, and navigation relies on buttons rather than touch, which some may find less intuitive. Also, certain advanced features like PacePro don’t work with all courses directly on the device, which might be limiting for some. While it isn’t packed with every smartwatch feature, the Forerunner 55 focuses well on core fitness tracking and training support, making it a reliable companion for those who want to track their workouts and health without getting overwhelmed by extras.
