10 Best Heart Monitors 2026 in the United States

The Apple Watch SE 3 is a well-rounded heart monitor packed inside a smartwatch. It uses a second-generation optical heart sensor that provides solid accuracy for heart rate tracking, along with notifications for unusual heart rhythms and high or low heart rates, which can be vital for health awareness. Its GPS and multiple connectivity options (Bluetooth, Wi-Fi) keep you connected when paired with an iPhone, although it relies on that connection for many features.

Battery life lasts about 18 hours, enough for daily use but requiring nightly charging, though fast charging is a helpful plus. The always-on, bright OLED display makes it easy to check your stats anytime without lifting your wrist. Comfort-wise, the lightweight aluminum case and soft sport band suit daily wear, fitting various wrist sizes.

Beyond heart monitoring, it includes extras like temperature sensing, sleep tracking with sleep apnea alerts, fall and crash detection, and mindfulness apps. While its fitness tracking is versatile, it might be more than needed if you only want a basic heart monitor. For best experience, using an iPhone is usually necessary. This device is ideal for users seeking a multi-functional, stylish smartwatch with reliable heart monitoring integrated into a broader health and safety toolkit.

The Samsung Galaxy Watch 7 40mm LTE is a solid choice for people looking for a smartwatch that combines heart-monitoring with everyday fitness and wellness tracking. It offers improved heart rate tracking that uses AI to filter out movement, aiming for more accurate readings during workouts. This is a big plus if you want reliable insights into your heart health while exercising. The watch also monitors sleep patterns and can detect signs of moderate to severe sleep apnea, which adds valuable health information beyond just heart rate.

It connects via Bluetooth and cellular, allowing for freedom from your phone during activities, and includes built-in GPS for outdoor tracking. At 28.8 grams and with a lightweight design, it’s comfortable to wear all day and night, which is important since consistent usage improves data accuracy. Battery life specifics aren't detailed here, but Samsung smartwatches typically last about a day or two under normal use. The watch’s Energy Score and Wellness Tips features provide personalized guidance, helping users stay motivated and informed about their health trends.

On the downside, the watch runs on Samsung's Tizen OS, which may have fewer third-party apps compared to other platforms like Apple Watch. Also, battery life might not meet the needs of users wanting extended use without frequent charging. This smartwatch suits fitness enthusiasts and health-conscious users who want detailed heart monitoring alongside sleep and energy tracking, wrapped in a comfortable and stylish device with strong connectivity options.

The Samsung Galaxy Watch 7 44mm LTE is a versatile smartwatch that includes advanced heart-monitoring features suitable for users interested in tracking their heart health alongside general wellness. It offers improved heart rate tracking using AI to filter out movement, providing more accurate readings during workouts. With cellular connectivity, you can stay connected without needing your phone nearby, although it lacks built-in GPS, which might be a downside if you want detailed route tracking for runs or bike rides.

The watch's battery life is moderate, supported by an alkaline cell with 100mAh capacity, so it may require daily charging depending on usage. Comfort-wise, it’s lightweight and has a 44mm round touchscreen, making it comfortable for most wrists and easy to use. Additional features like sleep monitoring that detects potential sleep apnea, personalized energy scores, and wellness tips add value by giving you insights beyond just heart data.

This watch suits fitness enthusiasts or anyone wanting a smartwatch with strong heart health features and AI-driven wellness insights, but those needing GPS tracking or longer battery life might want to consider other options.
