10 Best Heart Monitor Watches 2025 in the United States

The Garmin vívoactive 5 is a feature-rich health and fitness GPS smartwatch that stands out in the heart-monitor-watches category. It boasts an AMOLED display, which is bright and colorful, providing clear visibility. The heart rate monitoring is reliable and offers a comprehensive overview of your health by tracking various metrics like sleep, stress, and workouts. One of the most impressive aspects is its battery life, which can last up to 11 days in smartwatch mode, reducing the need for frequent charging.

The watch supports multiple sports and activities, including a unique wheelchair mode, making it suitable for a wide range of users. Water resistance allows for use during swimming, and the built-in GPS is great for outdoor activities like running and cycling. Connectivity options like Bluetooth, Wi-Fi, and USB ensure easy data syncing and access to music downloads from popular services like Spotify.

On the downside, the 1.2-inch display might be a bit small for users who prefer larger screens, and the 4 GB storage could be limiting for those who want to store a lot of music or apps directly on the watch. Additionally, while the watch offers extensive health monitoring features, the data presented aims to be a close estimation rather than absolute precision. These factors should be considered, but the Garmin vívoactive 5 is a fantastic choice for users looking for a versatile and long-lasting smartwatch with robust health and fitness tracking capabilities.

The Apple Watch Series 11 is a strong choice if you're looking for a heart monitor watch that goes beyond basic tracking. It offers advanced heart health features like ECG readings, notifications for irregular rhythms, high and low heart rates, and even hypertension warnings. Sleep tracking with a Sleep Score and sleep apnea notifications adds valuable insights into your rest quality.

The built-in GPS and multiple workout metrics make it a capable fitness companion, while the design is slim, lightweight, and comfortable enough to wear all day and night. Battery life supports about 24 hours of regular use, which means daily charging is needed, but fast charging helps top it up quickly. Its water resistance up to 50 meters and dust resistance make it durable for everyday use, including swimming. Compatibility is seamless for iPhone users, with features like calls, texts, Siri, and Apple Fitness+ integration boosting the experience.

A potential downside is that the 24-hour battery life may feel limiting compared to some competitors offering longer use, and it requires an iPhone to unlock its full potential. While the price tends to be higher than basic heart watches, the Apple Watch Series 11 offers a comprehensive package for those wanting detailed health monitoring combined with smart features and stylish design.

The Fitbit Charge 6 Fitness Tracker is a robust choice for anyone looking to enhance their fitness routine with advanced health monitoring features. One of its biggest strengths is the comprehensive heart rate monitoring, which not only tracks your heart rate 24/7 but also displays it in real-time when linked with compatible exercise machines. This feature is particularly useful for those who want to keep a close watch on their cardiovascular health during workouts. Additionally, the built-in GPS ensures accurate tracking of your outdoor activities, providing turn-by-turn directions via Google Maps, which is a significant plus for runners and cyclists.

The device also includes a range of health metrics such as stress management scores, sleep tracking, and daily readiness scores, giving users a well-rounded view of their health. With water resistance, the Fitbit Charge 6 allows users to wear it confidently during various activities, including swimming. Compatibility with both iOS and Android devices makes it accessible to a wide range of users. The design is sleek and comfortable, with the inclusion of both S and L bands to ensure a good fit for different wrist sizes.

The 1.04-inch screen might be considered small by some users, which could affect readability. A standout feature is the integration with Google apps, including Google Wallet for contactless payments and YouTube Music controls, enhancing its functionality beyond just fitness tracking. The Fitbit Charge 6 is well-suited for fitness enthusiasts who want a comprehensive health monitoring tool with the convenience of smart features, though the screen size and potentially frequent charging could be minor drawbacks.
