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.

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.

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.
