10 Best Swimming Activity Trackers 2026 in the United States

The COROS VERTIX 2S is a rugged adventure watch designed for outdoor enthusiasts, offering features that appeal to swimmers seeking a durable, multi-sport tracker. It has an impressive battery life, running up to 40 days on regular use and 118 hours with full GPS, reducing the need for frequent charging. The watch includes accurate heart rate monitoring with a next-generation optical sensor, which helps track fitness progress even during swimming.

While specialized swimming metrics like stroke count or lap tracking are not explicitly detailed, the watch's robust water resistance and strong build—featuring a sapphire screen and titanium bezel—make it well suited for water exposure and tough conditions. Tactile buttons and a large display facilitate easy operation under wet conditions or when wearing gloves, benefiting swimmers training in colder environments. Bluetooth connectivity allows data syncing, and on-wrist global maps support navigation for open water swimming.

The watch might lack some swim-specific features such as detailed swim analytics or automatic pool length detection found in dedicated swim trackers. It is relatively lightweight at under 9 ounces, although its size may feel bulky on smaller wrists. This makes the COROS VERTIX 2S a suitable choice for swimmers seeking a durable, long-lasting GPS watch with solid heart rate tracking and multi-sport capabilities, while casual swimmers primarily interested in swim-specific tracking might find it more than necessary.

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 Samsung Galaxy Fit 3 is a solid choice if you want a fitness tracker that can handle swimming and daily activities. Its 5ATM and IP68 water resistance means you can wear it in the pool without worry, making it swim-ready. It supports over 100 exercise modes with automatic workout detection, which likely includes swimming, though it doesn’t have built-in GPS if you are looking to track your swim routes or outdoor activities precisely.

The bright 1.6-inch AMOLED screen is easy to read underwater or in bright sunlight, and the lightweight design (just 36.8 grams) offers a comfortable fit for extended wear. Heart rate monitoring and advanced health features like SpO2 and sleep coaching add extra value for those who want more than just swim tracking. Battery life is impressive, lasting up to 14 days on a single charge, so you won’t need to recharge frequently. It connects via Bluetooth to both Android and iOS devices, though Samsung Pay is not supported.

The lack of a warranty in the US might be a concern for some buyers. If you want a budget-friendly, swim-ready activity tracker with long battery life and good health monitoring, the Galaxy Fit 3 fits well. However, if you need GPS tracking or US warranty support, you might want to consider other options.
