The Best Waterproof Fitness Trackers for Swimming: Reviewed and Ranked

Swimming is one of the best full-body workouts you can do. It builds endurance, strength and cardiovascular fitness. It also helps maintain a healthy weight, boost mood, and reduce stress.

If you want to get the most out of your swim sessions, using a waterproof fitness tracker can be extremely beneficial. These devices allow you to closely monitor metrics like lap count, distance, strokes, pace and more. Having access to this data makes it easier to structure your workouts, set goals, and track your performance over time.

But with so many swimming trackers now available, it can be tricky to determine which is right for your needs and budget. This guide will overview the top waterproof fitness trackers in 2023 specifically designed for tracking swim workouts and offer advice to help you find your perfect match.

How to Choose the Best Waterproof Swim Tracker

Here are the key factors to consider when selecting a waterproof fitness tracker for swimming:

Water Resistance

Since these devices are worn in the water, it‘s crucial to pick one with adequate water resistance. Most trackers designed for swimming have waterproof ratings between 5ATM (safe for showering and surface swimming) up to 10ATM for recreational scuba diving. Be sure to verify the exact depth rating before purchase.


To provide useful swim data, the tracker needs to accurately record metrics like lap count, stroke type, distance, pace, heart rate and more. GPS can assist with elements like distance and speed. Look for sensors capable of tracking advanced swim metrics.

Battery Life

Frequent charging will be inconvenient with aquatic activities. Seek out trackers offering battery life of 5-7 days minimum, or those with power-saving modes. Charging time is also worth noting.

Display Readability

You need to be able to view your real-time data easily while swimming, so the display must be sufficiently large and bright enough to see underwater. Color screens are ideal.

Swim-Specific Features

Many fitness trackers have pre-set activity modes for swimming and pool workouts. This allows the device to automatically detect and record swimming-related data. Other useful features include open water tracking, drill logging, etc.


Swimming trackers range from $100 to $800+ depending on the brand and included capabilities. Set your budget then seek out devices matching your needs at that price point.

Now let‘s review the top waterproof fitness trackers recommended specifically for tracking swimming exercises and monitoring performance.

Tune the settings – Initially, take some time to personalize your device settings like inputting accurate personal stats, selecting preferred units of measurement, enabling needed smartphone connections and more. Refer to the product manual for specifics.

Learn the metrics – Understand what metrics like pace, distance per stroke, efficiency score, heart rate zones and more are telling you about the intensity and quality of your workout. Use this data to structure optimal swim sessions.

Analyze the app data – Sync your tracker with the compatible mobile app or online dashboard after each session. Review your performance across multiple parameters over time to quantify improvement. Gauge where you still need work.

Use alerts & pacing – Take advantage of alerts that can notify you when you hit targeted pace, distance or heart rate zones. Pacing features are particularly useful for interval training.

Experiment with drills – Logging kick, pull or stroke modification drills is supported by some devices. Isolate aspects needing improvement then check if the focused work leads to better overall session metrics down the line.

Customize displays – For ease of use in the water, set your primary exercise display(s) to prominently showcase the 1-3 metrics most important to your training goals via large numerical readouts without scrolling through lots of data.

Conserve battery – Limit battery drain by enabling low power modes, disabling unneeded sensors, reducing unnecessary smartphone syncing and more. Plan charging around your swim schedule.
