10 Best ECG Watches 2025 in the United States

The Apple Watch Series 10 is a versatile smartwatch that excels in the ECG category, making it a strong choice for fitness enthusiasts and health-conscious users. One of its standout features is the ECG accuracy, allowing users to take heart readings anytime, which can be invaluable for monitoring heart health. The watch also provides notifications for irregular heart rhythms and abnormal heart rates, enhancing its health-tracking capabilities.

Battery life is decent, with fast charging capabilities, allowing users to recharge 80% in about 30 minutes. However, heavy users who frequently engage with features like GPS and health tracking might find the need to charge it daily. Its water resistance of up to 50 meters is a significant plus, making it suitable for swimmers or those who enjoy water sports.

The larger and higher-quality display improves usability and visibility, especially when interacting with various apps and notifications. Compatibility with Apple devices is seamless, allowing for easy integration into an Apple ecosystem, which is great for existing Apple users. The watch's additional health features, like tracking sleep and menstrual cycles, cater to a broad range of health needs. Individuals who do not own an iPhone might find this watch less useful, as many of its features are optimized for iOS. The customization options for watch faces and bands add a personal touch, but finding a variety of third-party apps can be limited compared to other platforms. Additionally, the watch's higher price point could be a drawback for budget-conscious consumers.

The Fitbit Sense 2 is a solid choice for those looking for an advanced ECG watch that doubles as a comprehensive health and fitness tracker. Its ECG accuracy is commendable, allowing users to monitor their heart health effectively, which is crucial for those at risk of atrial fibrillation. The watch also boasts a long battery life, typically lasting over six days, reducing the hassle of frequent recharging. Additionally, it's water-resistant up to 50 meters, making it suitable for swimming or other water activities.

The display quality is sharp and user-friendly, featuring a 1.69-inch touchscreen that enhances interaction. Beyond heart monitoring, the Sense 2 includes additional health features like SpO2 tracking, stress management tools, and a detailed sleep analysis system. These can be particularly beneficial for anyone looking to improve their overall wellness.

However, there are some drawbacks to consider. While the ECG app is useful, it may not be as comprehensive as those found in other high-end medical-grade devices, which could limit its appeal for users needing more extensive heart health monitoring. Also, while compatibility with both iOS and Android is a plus, some features, like Google Maps, are only available on Android for now, which could alienate iPhone users. Ease of use is generally good, but setting up some advanced features may require a bit of a learning curve for less tech-savvy individuals. Lastly, while a six-month Premium membership is included, continuous access to advanced features afterward may incur additional costs, which could be a downside for some users.

The Fitbit Sense 2 is ideal for fitness enthusiasts and individuals looking to manage their health proactively, but those needing extensive medical-grade ECG monitoring or who prefer a no-cost service might find it lacking.

The Apple Watch Series 9 is a top contender in the ECG-watch category, designed for those who prioritize health and fitness tracking. One of its strongest features is ECG accuracy, allowing users to take heart readings at any time and receive alerts for irregular rhythms. Coupled with advanced health metrics like sleep tracking and temperature sensing, it offers a comprehensive view of your wellbeing.

Battery life is generally good, but heavy users may find themselves needing to recharge frequently, especially with the always-on display feature. The display quality is impressive; the S9 chip enables a bright and responsive interface that enhances usability. The watch is also water-resistant to 50 meters, making it suitable for swimming and workouts, which is a significant advantage for fitness enthusiasts.

In terms of compatibility, it works seamlessly with newer Apple devices, but users with older iPhones may find it less useful, as it requires an iPhone XS or later. This can be limiting for those who are not fully integrated into the Apple ecosystem. While the Apple Watch Series 9 is customizable with various bands and watch faces, some users might prefer more traditional designs or additional features that other brands offer.

Ease of use is a highlight, thanks to its intuitive interface and voice control features. However, the advanced features may be overwhelming for users who are not tech-savvy. The watch offers a range of additional health features, including a workout app and safety alerts like fall detection, making it a reliable companion for fitness and health tracking.

The Apple Watch Series 9 excels in ECG capabilities and integrated health insights, but its dependency on the Apple ecosystem and relatively frequent recharging may discourage some users. For those seeking a comprehensive health companion who already uses Apple products, it stands out as an excellent choice.
