The Best Waterproof Fitness Trackers We’ve Tested for 2025

Apple’s flagship smartwatch, the Series 11, has a WR50 rating, meaning it’s water-resistant to 164 feet and suitable for shallow-water activities, such as swimming in a pool or the ocean close to shore. It’s also safe to wear in the shower or a hot tub. Its Workout app offers separate tracking options for pool and open-water swimming, as well as a multisport mode for triathletes. The Series 11 also has an IP6X certification, meaning it’s totally dustproof and immune to damage from sand, making it ideal for beach wear. This model also includes Apple’s excellent Depth app and a water temperature sensor, features that were previously limited to the Ultra series. The Series 11’s big, bright screen makes it very easy to see your real-time depth, even in murky water conditions. 5G connectivity will allow you to leave your phone behind on beach day and still benefit from speedy performance.

The Apple Watch Series 11 is an excellent option for those seeking a smartwatch that tracks swimming and keeps you connected outside the water. It requires an iPhone 11 or later running iOS 26 or higher, so it’s not an option if you use Android. Note that the Series 11 is not safe for scuba diving, waterskiing, or other activities involving high-velocity water or deep submersion.

Fitbit’s most popular fitness tracker, the Charge 6, is water resistant to 164 feet and safe to wear in the rain or pool. The Exercise app offers a tracking option for swimming, and the device features a Water Lock setting, which prevents the screen from activating when you’re in the water. The Water Lock automatically turns on when you start a swim in the Exercise app, or you can enable it anytime via the Quick Settings menu. Additionally, Fitbit’s SmartTrack feature automatically recognizes and records certain types of workouts, including swimming.

The Charge 6 is an excellent investment for casual swimmers and anyone who wants to improve their health without spending a bundle. Note that Fitbit cautions against regularly wearing the Charge 6 in the shower, as exposure to soaps and conditioners may diminish its water resistance. It’s not safe for the hot tub or sauna, either. Regular beachgoers and outdoor adventurers should consider a more rugged device because the Charge 6 has no dust protection rating.

Just because you’re swimming doesn’t mean you need to sacrifice your sense of fashion. Like many other models on this list, the Garmin Lily 2 has a 5ATM water resistance rating, so you can safely swim with it to a depth of 164 feet. It includes an exercise mode for pool swimming and tracks a variety of other health attributes like sleep, heart rate, and SpO2 when you’re not doing laps. Beyond the useful functionality, what this watch really has going for it is a chic design and a large variety of interchangeable straps.

The Garmin Lily 2 is a top pick for women, specifically given its size and swagger, but it’s one of the best fitness trackers out there for anyone with small wrists or a penchant for style. It can’t track open-water swimming, but it’ll look good while you’re putting in those pool laps.

The Garmin Venu Sq 2 has a 5ATM water-resistance rating, meaning it can withstand pressure at depths of up to 164 feet and is safe to wear in the shower or pool. It offers over 25 built-in indoor and GPS profiles, including pool swimming, rowing, and SUP. For swimming, it tracks metrics including underwater heart rate, stroke type, and SWOLF (a measure of swimming efficiency). 

The Venu Sq 2 is a top choice if you need a waterproof fitness tracker with long battery life. In testing, it ran for around nine days. It doesn’t track open water swimming, but it’s reasonably priced and practical in design.

The Samsung Galaxy Fit3 is both attractively priced and highly adept at tracking exercise. During workouts, it tracks heart rate as accurately as devices that cost several times more. It can track over 100 different types of workouts, and it’s water-resistant to 164 feet deep.

If you have an Android phone and don’t need something fancy, the Galaxy Fit3 works well and is safe to wear in the water. It can even automatically track swimming and other high-movement activities.

The Galaxy Watch FE is an affordable Android smartwatch that features 5ATM and IP68 ratings, so it’s waterproof to depths of 164 feet and can withstand dust, dirt, and sand. It also meets the MIL-STD-810H standard, so it should survive extreme temperatures and other environmental stressors such as vibration and shock. The Watch FE offers more than 90 activity options, including aqua aerobics, beach volleyball, kayaking, rowing, snowshoeing, swimming, and water skiing. It also features a Water Lock mode to prevent the screen from activating when you’re in the water. Finally, access to the Google Play Store means you can download a wide selection of apps.

The Samsung Galaxy Watch FE is best for Android users who need a waterproof smartwatch with robust connectivity and health features. It’s a nice option for pool and open water swimmers, even if it’s not rugged enough for diving or high-velocity water sports. The Galaxy Watch FE is exclusive to phones running Android 10.0 (or newer), though you get even more features like snoring detection if you pair it with a Samsung phone specifically.

The Oura Ring 4 tracks activity, sleep, and stress from the tiny, accurate sensors embedded in its stylish frame. It fits comfortably and excels at compiling holistic health insights like cardiovascular age, sleep regularity, and more over time. Additionally, it’s water resistant to depths of 328 feet and suitable for shallow water sports, and it tracks up to 40 different types of exercise.

If you want to track your heart rate during a swimming workout, but don’t like the feel of a wrist-based tracker in the water, the Oura Ring 4 will give you the data you need from its discreet spot on your finger. It doesn’t offer much in the way of workout details, but it tracks the basics and offers excellent holistic health insights.

The Watch SE 3 is Apple’s smallest and most affordable smartwatch, featuring the same processor as Apple’s flagship model, along with extended battery life. It needs to be used with care around sand because it lacks a dust-resistance rating, but thanks to its WR50 rating, it’s safe to wear while swimming or showering.

The Apple Watch SE 3 will monitor your water activities on a budget. It offers pool swimming, open-water swimming, and multisport (triathlon) tracking options.

Apple’s rugged Watch Ultra 3 has a WR100 rating, which means it can withstand depths of up to 328 feet, and it’s durable enough for high-speed water sports like kitesurfing, wakeboarding, and jet skiing. It also meets the EN13319 international standard for dive computers and gauges and is safe for recreational scuba diving down to 130 feet. The Ultra 3 has MIL-STD 810H certification, meaning it can withstand high altitudes, extreme temperatures, freezing/thawing, blowing sand, and other environmental stressors, including vibrations and shocks. It features a bright screen that is easy to read, even in direct sunlight, thanks to its wide-angle OLED technology, which enhances visibility. 5G connectivity keeps it feeling speedy when away from your phone, and Emergency Satellite Connectivity allows you to signal for help even when off the grid with no service.

With long battery life, military-grade durability, and satellite connectivity for emergencies, the Ultra 3 is the best Apple Watch for outdoor adventurers, endurance athletes, and ocean enthusiasts. Thanks to its depth gauge and water temperature sensor, it’s also a nice option for scuba divers. Divers should check out the Oceanic+ app, which turns the Ultra 3 into a dive computer.

The Fitbit Versa 4 is water-resistant to 164 feet, which means you can wear it in the shower or while you swim (even in salt water) without issue. Fitbit advises against bringing it into a hot tub or sauna, however. The Versa 4’s Exercise app offers a tracking option for swimming and supports SmartTrack automatic exercise recognition. It also provides helpful heart rate zone alerts to let you know when you reach a target zone during exercise.

The swim-friendly Versa 4 is a compelling option for Fitbit fans as it’s both affordable and offers multi-day battery life.

The Fitbit Ace 3 is a swim-friendly fitness tracker for children. It’s water-resistant up to 164 feet and can withstand cannonballs. Outside the water, it tracks your little one’s active minutes, hourly movement, sleep, and step count.

The Ace 3 is ideal for children ages six and up. It offers an impressive eight days of battery life, just note that it doesn’t have any kind of location tracking or apps.
