10 Best Heart Rate Monitor Watches 2025 in the United States

The Apple Watch Series 11 GPS 42mm is a strong choice for anyone looking for a smartwatch that excels in heart rate monitoring and comprehensive health tracking. It features advanced sensors including electrical and optical heart sensors, blood oxygen, and temperature sensors, which allow it to detect high and low heart rates, irregular rhythms, sleep apnea, and even signs of hypertension. The addition of ECG capabilities and a comprehensive sleep score makes it an excellent health companion beyond just fitness tracking.

Battery life supports about 24 hours of regular use, with a helpful low power mode extending it to 38 hours. Fast charging is a plus—it can provide up to 8 hours of use in just 15 minutes. The watch is water resistant up to 50 meters and dust resistant (IP6X), making it durable for swimming and outdoor activities. Connectivity options are extensive, including GPS (with support for multiple satellite systems), 5G, LTE, Wi-Fi, and Bluetooth 5.3, ensuring reliable syncing and navigation. The built-in GPS supports accurate tracking for runs and other workouts.

Design-wise, it is thin, lightweight, and comfortable to wear all day and night, ideal for continuous health monitoring. The always-on Retina display is bright and clear, with durable glass that resists scratches well. The watch offers many useful features like fall and crash detection, emergency SOS, mindfulness apps, and medication reminders, making it a comprehensive health and safety device. Some drawbacks include the 24-hour battery life necessitating daily charging for heavy users and the requirement of an iPhone for full functionality of some advanced health notifications. The price tends to be higher compared to simpler heart rate monitors. This watch is best suited for users seeking a multifunctional smartwatch with top-tier health and fitness tracking, strong safety features, and excellent connectivity in a stylish, comfortable design.

The Apple Watch SE 3 (GPS, 44mm) is a strong choice if you're looking for a heart-rate monitoring watch that fits well into everyday life and fitness routines. Its heart rate sensor is accurate enough for most users, offering helpful alerts for high, low, or irregular heart rhythms, which adds peace of mind about your health. The watch also includes temperature sensing and sleep tracking with useful insights like sleep scores and sleep apnea notifications, making it more than just a basic heart rate monitor.

Battery life lasts about 18 hours with normal use, which should comfortably cover a full day, and it charges quickly - 15 minutes of charging can give you up to 8 hours of use. This is convenient if you want to top up during short breaks. The watch is water resistant, so you can wear it while swimming or in the rain without worry. Built-in GPS and support for multiple satellite systems provide reliable outdoor navigation and workout tracking without needing your phone nearby. It connects seamlessly with your iPhone for calls, texts, music, and Siri, but it does not have cellular capability in this GPS-only model, so you need your phone nearby for full connectivity.

Design-wise, the 44mm aluminum case and sport band offer a comfortable fit for most wrists, and the always-on Retina display keeps the screen visible without needing to lift your wrist. While it covers a wide range of health and fitness features and has a user-friendly interface, the battery life is not the longest compared to some other brands focused solely on sports. Some advanced health features like ECG or blood oxygen monitoring are not included in this SE model. This makes the Apple Watch SE 3 a versatile, stylish smartwatch with reliable heart rate monitoring, solid fitness tracking, and smooth integration with an iPhone, especially suitable for casual fitness enthusiasts and Apple users.

The Fitbit Inspire 3 is a well-rounded heart-rate-monitor watch, designed to help users stay active and manage their health. One of its key strengths is its accurate heart rate monitoring, which works 24/7 to provide real-time insights. The device also tracks various health metrics, such as stress levels, sleep patterns, and menstrual health, making it a comprehensive tool for overall wellness.

The battery life is impressive, lasting up to 10 days on a single charge, ensuring you won't need to charge it frequently. Additionally, it boasts water resistance up to 50 meters, making it suitable for swimming and other water activities. The watch is lightweight and comes with both S and L bands, ensuring a comfortable fit for most users. Connectivity is handled through Bluetooth, and it supports notifications for calls, texts, and apps, which is handy for staying connected without needing to check your phone constantly.

However, its GPS capability is reliant on your smartphone, which might be a drawback for those who prefer a standalone GPS feature. The small screen size of 0.76 inches may also be a concern for users who prefer larger displays. Despite these minor drawbacks, the Fitbit Inspire 3 offers a robust set of features at a competitive price, making it a great choice for anyone looking to monitor their heart rate and overall health.
