10 Best Smartwatch That Works Without Phone 2025 in the United States

The Apple Watch Series 10 (GPS + Cellular 42mm) is a strong choice if you want a smartwatch that works well without needing your phone nearby. Thanks to its cellular connectivity, you can send texts, make calls, and stream music directly from the watch. The battery life offers up to 18 hours of normal use, which covers a full day, and it charges quickly—80% in about 30 minutes—so it's convenient for daily wear. It runs on watchOS, providing smooth performance and access to many apps, especially if you're already using other Apple devices.

Health and fitness tracking is a major plus here. You get advanced features like ECG, heart rate alerts, sleep tracking with apnea notifications, and support for a wide variety of workouts, including swimming, thanks to its 50m water resistance. Safety features like fall detection and crash detection add peace of mind. The always-on Retina display is bright and clear with a bigger screen area than before, making it easy to read notifications and track your activity.

Durability is solid with crack-resistant glass and dust resistance (IP6X), suitable for active lifestyles. AppleCare+ adds extra protection against accidental damage, which could be worth considering given the premium price. The battery life, while decent, may require daily charging for heavy users. Also, the watch is designed primarily to work best with iPhones (models Xs and newer), so it’s not the best fit if you use Android phones. Finally, the cost is quite high, but you get a feature-rich, reliable device that excels in health monitoring and seamless integration with Apple services. For those invested in the Apple ecosystem seeking a high-quality, standalone smartwatch with excellent health and safety features, the Series 10 presents a compelling option.

The Apple Watch Series 10 is a feature-rich smartwatch that offers impressive functionality, particularly for those who want a device that works well without the need for a phone. Its cellular connectivity allows users to send texts, make calls, and receive notifications even when away from their iPhone. The always-on Retina display provides excellent visibility, which is particularly useful during workouts or outdoor activities. The health and fitness tracking capabilities are standout features, including an ECG app, heart rate monitoring, and various workout tracking options. Users will appreciate the extensive app ecosystem, especially with the complimentary access to Apple Fitness+ for three months.

On the durability front, the watch boasts a robust design with IP6X dust resistance and a water resistance rating of 50 meters, making it suitable for various sports and even swimming. The battery life can last up to 18 hours with regular use, and the fast charging feature enables a quick boost, providing 80% charge in about 30 minutes.

There are some drawbacks. First, the Apple Watch Series 10 is primarily optimized for iPhone users; its full range of features is not available for Android users, which limits its appeal. The battery life, while decent, may fall short for users who need a multi-day performance, especially if using features like sleep tracking extensively. Moreover, the premium pricing might deter some potential buyers, particularly those looking for more budget-friendly options.

The Apple Watch Series 10 is well-suited for fitness enthusiasts and those who want a reliable smartwatch that operates independently. It excels in health tracking and cellular connectivity, but its compatibility limits and pricing could be potential factors to consider for some users.

The Fitbit Versa 4 Fitness Smartwatch is designed for users seeking a functional smartwatch that operates without the constant need for a smartphone. One of its key strengths is its cellular connectivity, allowing for on-wrist calls and notifications, which makes it convenient for those who prefer to keep their phone out of reach during workouts or daily activities. With a built-in GPS and over 40 exercise modes, it caters well to fitness enthusiasts by providing real-time stats and automatic exercise tracking.

Battery life is impressive, lasting over six days, which is beneficial for users who want a device that can keep up with their busy routines without frequent charging. The health and fitness tracking features are robust, including heart rate monitoring, sleep tracking, and stress management tools, making it a great option for individuals focused on wellness.

However, there are some drawbacks to consider. While the smartwatch is water-resistant up to 50 meters, the durability and build quality may not be as premium as some competitors in the market. The display quality, while adequate, may not stand out compared to more advanced smartwatches. Additionally, the app ecosystem is somewhat limited when compared to other brands, which might be a concern for users looking for a wide range of applications. The Fitbit OS supports essential functionalities but could lack some advanced features found in other operating systems. Compatibility with Apple and Android devices is a plus, but some features, like Google Maps for iOS, are still pending release.

The Fitbit Versa 4 is a solid choice for fitness-focused individuals looking for a smartwatch that can operate independently from their phones. It combines essential health tracking, good battery life, and cellular capabilities but may lag in premium build quality and app variety.
