10 Best Heart Monitor Watches 2025 in the United States

The Apple Watch Series 11 (GPS 46mm) is a strong choice for anyone interested in a heart-monitor watch with lots of health features packed in a sleek, lightweight design. It offers advanced heart rate monitoring, including notifications for high or low heart rates, irregular rhythms, and hypertension signs, which can be helpful for users wanting detailed heart health insights. The watch also tracks sleep quality and offers a unique sleep score, plus it can detect possible sleep apnea—features not always found in other heart monitors.

GPS tracking is built-in and reliable, supporting various global systems, making it suitable for outdoor activities and workouts. Battery life allows for up to 24 hours of normal use, which covers a full day but might require daily charging if used extensively—though fast charging helps with this. Water resistance up to 50 meters and dust resistance (IP6X) mean it’s durable enough for swimming and everyday wear without worry.

Compatibility with iPhones ensures smooth connectivity for calls, texts, music, and Siri, but it is limited if you don’t use an iPhone. The watch adds safety features like fall and crash detection, which can be a real bonus. Some health functions like ECG or blood oxygen readings are not a replacement for professional medical tools and require you to carefully follow usage guidelines. If you want a reliable, stylish heart-monitor watch that also supports fitness tracking and everyday smart features, the Series 11 is a solid pick—just keep in mind the battery life and iPhone-only compatibility.

The Apple Watch Series 10 stands out as a robust choice for those seeking a heart-monitor watch with added features. Its heart rate monitoring is comprehensive, offering ECG capabilities and alerts for irregular heart rhythms, making it an excellent health companion. The integration with Apple's ecosystem ensures seamless compatibility for iPhone users, enhancing its usability.

In terms of GPS tracking, the watch excels, supporting multiple satellite systems for precise location tracking. This is particularly beneficial for outdoor activities like running, hiking, and cycling. Its water resistance up to 50 meters also makes it suitable for swimming and other aquatic sports.

Battery life, while decent, is where some users might find a drawback. With up to 18 hours of regular use, it may require daily charging, though the fast-charging feature mitigates this by reaching 80% in about 30 minutes. For extended battery life, the low power mode provides up to 36 hours, which can be handy during longer excursions.

The design of the Series 10 is sleek and comfortable, with a larger display that enhances readability and interaction. The array of health metrics, including sleep tracking and menstrual cycle insights, offer comprehensive health management.

On the downside, its advanced features are primarily accessible within the Apple ecosystem, which could limit its appeal to non-iPhone users. Additionally, the premium build and features come with a higher price tag, which might not fit every budget.

In conclusion, the Apple Watch Series 10 is well-suited for those invested in the Apple ecosystem looking for a multi-functional heart-monitor watch that goes beyond basic fitness tracking. Its design, advanced health insights, and connectivity options make it a versatile device for tech-savvy users prioritizing health and fitness.

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.
