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 Apple Watch SE (2nd Gen) is a solid choice for those looking for a smartwatch that can operate without being tethered to a phone. With cellular connectivity, it allows you to stay in touch through calls, texts, and music streaming, making it highly functional for those who want to remain connected while on the move. The watch is powered by watchOS 11, which enhances personalization and connectivity, bringing a user-friendly experience. The health and safety features are impressive, including heart rate monitoring, fall detection, and emergency SOS—great for anyone prioritizing fitness and safety.

Battery life is decent, but like many smartwatches, heavy use of cellular features may require more frequent charging. The display quality is excellent, featuring a Retina display that is bright and clear for easy visibility. Durability is another strong point, with water resistance up to 50 meters, making it suitable for swimming and other outdoor activities.

One of the standout features is its compatibility with Apple devices, allowing for seamless integration with services like Apple Pay and automatic unlocking of your Mac. However, it’s worth noting that while the watch can function on its own, some features are still reliant on having an iPhone nearby, especially for initial setup and certain app functionalities. The app ecosystem is robust, but users who prefer non-Apple devices may find limited options for compatibility. Customization options for watch faces and bands are plentiful, which is a plus for those who want a personalized look. The price may be a consideration for some, as it sits higher than many competitors in the market. Additionally, for those not in the Apple ecosystem, the benefits might be diminished. The Apple Watch SE (2nd Gen) is a great option for fitness enthusiasts and those who value connectivity, particularly if they are already using Apple products.
