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 Apple Watch Series 9 (GPS, 41mm) is an excellent fitness tracker for iPhone users who want a feature-rich and stylish smartwatch. It works seamlessly with iPhones (XS or later), offering smooth integration with apps and services like Apple Pay and Fitness+. The watch features a bright Always-On Retina display which is easy to see during workouts or daily wear. Battery life generally lasts about a day, so you’ll likely need to charge it overnight, which is typical for smartwatches with many features.

For fitness and health tracking, it covers all the essentials: accurate heart rate monitoring, built-in GPS for tracking outdoor activities, and detailed sleep tracking that shows different sleep stages. It also includes advanced health features like ECG and temperature sensing, which can provide deeper insights into your wellbeing beyond just basic step counting. The device is swimproof with 50m water resistance and dust resistant, making it durable enough for various environments. Safety features like Fall Detection and Crash Detection add extra peace of mind, especially if you’re active or spend time outdoors.

You’ll also stay connected with notifications, calls, texts, music control, and Siri voice control right on your wrist, so you don’t have to pull out your phone constantly. The watch is customizable with different bands and faces to match your style, and the lightweight aluminum case is comfortable for everyday wear. While it packs many advanced features, the battery life might feel short if you use GPS and health sensors heavily throughout the day. As a premium Apple product, it’s priced higher than basic fitness trackers. If you’re an iPhone user looking for a versatile, highly capable fitness tracker that doubles as a stylish smartwatch with deep health insights, the Apple Watch Series 9 is a strong choice. For those seeking simpler tracking or longer battery life, other options might be more suitable.

The Fitbit Versa 4 Fitness Smartwatch is a solid choice for iPhone users seeking a comprehensive fitness tracker. It excels in several key areas: compatibility, battery life, and heart rate monitoring. The watch works seamlessly with iPhones and offers robust connectivity through Bluetooth. With a battery life of over six days, it's reliable for long-term use without frequent charging. The heart rate monitoring is available 24/7, providing valuable insights into your fitness and health levels.

Additionally, the built-in GPS allows you to track your runs and outdoor activities accurately, without needing to carry your phone. The watch is water-resistant up to 50 meters, making it suitable for swimming and other water activities, and it includes 40+ exercise modes to cater to various workouts. Sleep tracking is another strong point, providing detailed analysis and personalized sleep profiles. The display is clear and customizable, making it easy to view stats and notifications at a glance. You can also receive smartphone notifications, make Bluetooth calls, and use built-in features like Amazon Alexa and Fitbit Pay.

However, there are a few drawbacks to consider. The product dimensions might not be comfortable for everyone, especially those with smaller wrists. Additionally, some features, such as Google Maps integration, are not yet available for iOS users but are expected in future updates. The initial six-month premium membership is a nice addition, but ongoing access will require a subscription. Despite these minor issues, the Fitbit Versa 4 offers a comprehensive set of features for fitness enthusiasts looking to track their health and stay connected on the go.
