10 Best Heart Rate Monitor For Swimming 2025 in the United States

The Polar H10 Heart Rate Monitor is a strong choice for swimmers and other athletes looking for an accurate and versatile heart rate tracking solution. Its waterproof design ensures it can handle the rigors of swimming, making it suitable for those who want to monitor their heart rate during water-based activities. One of its standout features is the supreme accuracy of heart rate tracking, which is especially appreciated by professional athletes. It pairs seamlessly with a variety of devices, including major sports watches and fitness apps—this means you can easily integrate it into your existing workout routine.

Comfort is often a concern with heart rate monitors, but the Polar H10 comes with a pro strap that has improved electrodes and a comfortable fit, allowing you to focus on your performance rather than your equipment. Its internal memory feature is a great bonus, as it lets you store data for one training session without needing to connect to a device.

There are a few drawbacks to consider. While it does boast excellent connectivity options, some users may find the initial setup a bit complicated, especially if they are not tech-savvy. Additionally, while the battery life is generally good, users should be aware that frequent use may require regular battery replacements. The strap size is limited to M-XXL, which could be a concern for those outside this range.

The LIVIKEY Fitness Tracker Watch is designed to offer a comprehensive range of features for those who lead active lifestyles. Its standout feature is the 5ATM waterproof rating, which makes it suitable for use in wet conditions, such as swimming or rainy workouts. However, it's important to note that while it's water-resistant, it doesn't specify suitability for deep diving or extended underwater use, which might be a consideration for serious swimmers.

In terms of heart rate monitoring, the watch provides continuous tracking throughout the day with an option for manual checks via an app. This feature is beneficial for users looking to keep an eye on their heart health both during workouts and rest periods. The sleep monitoring function adds another layer of health insight, offering a breakdown of sleep stages. However, the accuracy of data, particularly underwater, isn't specified, which might impact those looking for precise measurements during swim sessions.

Comfort and fit are crucial for wearables, and while this watch is lightweight at 2.39 ounces, the fit may vary depending on individual wrist sizes. The watch also boasts a decent battery life of 5-7 days on a full charge, which is convenient for regular users who prefer not to charge frequently.

Connectivity through Bluetooth allows users to receive notifications from their smartphones, but it's limited to viewing notifications only, as the watch doesn't support making calls or texting. With compatibility across both Android and iOS devices, it appeals to a wide audience, but the lack of GPS might be a downside for those who need location tracking during their activities.

The watch encompasses multiple fitness modes, but its additional features like smart notifications, sedentary alerts, and breathing guides might be more appealing to general fitness enthusiasts rather than specialized swimmers. Those seeking a dedicated swimming heart rate monitor might need to consider other options that offer enhanced accuracy and functionality specifically for aquatic environments.

The Polar Verity Sense is a solid choice for anyone seeking a heart rate monitor specifically designed for swimming. One of its standout features is its water resistance, which ensures it functions well in the pool, tracking your heart rate, distance, and pace automatically. The comfort factor is impressive too; it can be worn on your arm or attached to your goggles, allowing for a free range of movement while swimming. With its lightweight design at just 19 grams, it won’t feel bulky during your workouts.

When it comes to heart rate tracking technology, the Verity Sense uses optical sensors that provide good accuracy for most users, though some swimmers may find the readings slightly less precise compared to chest strap monitors, especially during intense activities. Battery life is decent, allowing for multiple swimming sessions, and it charges easily with the included unit.

The connectivity options are a significant plus; it supports both Bluetooth and ANT+, allowing you to connect to various devices and apps like Peloton and Zwift, making it versatile for different sports beyond swimming. You can monitor your heart rate in real-time or record your session for later review, catering to different preferences. However, while the device is compatible with many platforms, some users might find the lack of built-in display a bit inconvenient, as they need to rely on connected devices to view their stats immediately. Additionally, the size range might not fit everyone perfectly, as it is designed for M-XXL, which could limit options for those outside this range.
