10 Best Swimming Activity Trackers 2026 in the United States

The SUUNTO Ocean Dive Computer is a strong choice for serious swimmers and divers who want a device tailored for underwater activities. It offers excellent water resistance suitable for diving up to 100 meters and supports various dive modes like freediving, snorkeling, and multigas diving, making it versatile for different underwater experiences. The watch’s AMOLED touchscreen is bright and clear even underwater, which makes it easier to read your stats during a dive. It also has a built-in heart rate monitor that works throughout the day, helping track your fitness beyond swimming.

Battery life is impressive, lasting up to 40 hours in dive mode and up to 26 days in standby, with fast charging to minimize downtime. Its route tracking and dual-band GPS provide reliable navigation and underwater route recording, a significant advantage for those who enjoy exploring and want detailed logs of their dives. On the comfort side, while the watch is made with durable materials like sapphire crystal and stainless steel and weighs just under 100 grams, some users may find it bulkier compared to simpler swim trackers.

Connectivity is strong with Bluetooth and compatibility with the Suunto app, allowing syncing workouts and sharing dive logs easily. Beyond swim and dive features, it has over 95 sport modes and an AI coach to help monitor training and recovery. The advanced features cater to serious underwater activities and multisport tracking, but this device might be more than casual swimmers need, and the price and complexity could be considerations for those wanting basic swim tracking.

The Garmin Descent™ G1 is designed primarily as a rugged dive computer, making it highly suitable for serious divers. It features a sapphire lens and silicone bands, which ensure durability and a comfortable fit. The device offers multiple dive modes, making it versatile for different types of diving, including recreational, technical, and free diving. Its water resistance is top-notch, essential for underwater activities, though this might be more advanced than necessary for casual swimmers who just want basic swim tracking features.

Swim tracking and activity monitoring are robust with over 30 built-in sports apps, and it includes advanced training features such as VO2 Max, providing detailed insights into physical performance. Heart rate monitoring is available 24/7 along with other health metrics like Pulse Ox and sleep score, although it should be noted that Pulse Ox is not available in all countries and the device is not a medical tool. Battery life is impressive, lasting up to 21 days in smartwatch mode and 26 hours in GPS mode, which is convenient for extended usage without frequent recharging.

Connectivity and compatibility are solid, with support for Bluetooth, GPS/GLONASS/Galileo, and smart notifications when paired with a compatible smartphone. Garmin Pay and app personalization through Connect IQ add extra smartwatch functionalities. However, the monochrome display might not be as visually appealing as color screens, and the focus on advanced diving features might be excessive for general swimming activity tracking needs. In summary, the Garmin Descent™ G1 is ideal for dedicated divers seeking comprehensive underwater functionality, while casual swimmers may find its advanced features and rugged design beyond their requirements.

The Samsung Galaxy Fit 3 is a solid choice if you want a fitness tracker that’s swim-friendly and covers many exercise types. Its IP68 and 5ATM water resistance means it can handle swimming and daily water exposure without issues. The 1.6-inch AMOLED screen is bright and colorful, making it easy to check your stats even underwater or in bright sunlight. Battery life is impressive, lasting up to 14 days on a single charge, which is great for long-term use without frequent recharging. The Fit 3 tracks over 100 workout modes with automatic detection, including basic swim tracking, heart rate, sleep, and blood oxygen levels. However, it lacks more advanced swim-specific data like stroke count or lap detection, which serious swimmers might miss. Another point is there’s no built-in GPS, so distance tracking during open water swims won't be available.

Comfort-wise, its lightweight design and silicone band make it easy to wear all day and night. Connectivity is solid with Bluetooth compatibility for both Android and iOS devices, but Samsung Pay is not supported. Note that this international model comes without a US warranty, which might be a consideration. In summary, the Galaxy Fit 3 works well for casual swimmers and general fitness tracking, offering strong battery life and a clear display, but it’s not tailored for advanced swim metrics or outdoor swim tracking.
