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

The Samsung Galaxy Watch 7 44mm Bluetooth AI Smartwatch is a robust option for those seeking a smartwatch that can function independently of a phone. One of its standout features is its advanced tracking capabilities, including Energy Score, heart rate monitoring, and sleep tracking, which are all enhanced by Galaxy AI. This makes it a strong choice for fitness enthusiasts and those who want detailed health insights.

The watch offers Bluetooth connectivity, which is useful, but it lacks explicit mention of cellular connectivity, a critical feature for true phone independence. The watch has a sleek and durable build quality, and the touchscreen interface should be user-friendly. Samsung typically offers high-quality screens, which should translate into a good viewing experience.

The app ecosystem would largely depend on Samsung's Tizen OS or Wear OS, which are known for their robust app support. If you need a smartwatch for health and fitness tracking with some phone-independent features, this could be a good choice.

The Fitbit Sense 2 is a robust option for those seeking a smartwatch that functions well without a phone. One of its key strengths is the comprehensive health and fitness tracking capabilities, such as the ECG app for atrial fibrillation assessment, SpO2 monitoring, 24/7 heart rate tracking, and stress detection tools. This makes it particularly beneficial for users focused on maintaining or improving their health and fitness levels. Additionally, the built-in GPS is ideal for tracking outdoor activities without needing to carry a phone.

The Fitbit Sense 2 also excels in sleep tracking with features like personalized Sleep Profile, daily sleep stages, and a smart wake alarm, which can help users improve their sleep quality. The battery life, lasting over 6 days, is impressive and ensures users don’t need to charge it frequently. However, there are some limitations. While the Fitbit Sense 2 offers on-wrist Bluetooth calls and notifications, it relies on a phone for full functionality, which may not align perfectly with those looking for a completely independent device.

The app ecosystem, while growing, is still behind some competitors, limiting the variety of apps available. The durability is good with water resistance up to 50 meters, but the build quality, being lightweight at 1.3 ounces, may not feel as premium as other high-end smartwatches. The display quality is decent with a 1.69-inch screen, but it doesn’t stand out in the market crowded with higher resolution screens. For someone prioritizing health tracking, long battery life, and basic connectivity features, the Fitbit Sense 2 is a solid choice.

The Apple Watch Series 10 (GPS + Cellular, 46mm) is a strong choice for users seeking a smartwatch that works independently of their phone. Its built-in cellular connectivity allows you to make calls, send texts, and stream music without having your iPhone nearby, which is ideal for staying connected on the go. The watch runs on Apple’s latest operating system, ensuring smooth performance and access to a wide range of apps.

Battery life offers up to 18 hours under regular use, covering a full day, and it charges quickly, reaching 80% in about 30 minutes. However, heavy use of cellular features might drain the battery faster. The display is bright and sharp with an always-on Retina screen, making it easy to see in various lighting conditions. For fitness and health, it offers comprehensive tracking including ECG, sleep stages, heart rate alerts, and sleep apnea notifications, providing detailed health insights. It supports a variety of workouts and includes useful safety features like fall and crash detection.

The watch is durable with water resistance to 50 meters and dust resistance, making it suitable for outdoor activities and swimming. It works best within the Apple ecosystem, requiring an iPhone (Xs or newer) for setup and full functionality, which could be limiting if you don’t already have one. While the battery life may feel short with heavy GPS or cellular use, the Apple Watch Series 10 is a premium, well-rounded smartwatch ideal for iPhone users wanting a device capable of handling calls, fitness, and health monitoring without their phone nearby.
