Most Fitbits are designed to be swim-proof, so they can safely join you while doing laps at the pool or in the ocean. However, when you’re searching for the best Fitbits for swimming, you’ll first want to decide if you want just a fitness tracker or if you’d like smartwatch capabilities as well. Features such as built-in GPS, heart rhythm tracking, and the ability to make and receive Bluetooth calls are what sets the models apart. They also come in a variety of styles and price points, so it’s easy to find the perfect one.

What to consider when choosing a Fitbit for swimming

Most Fitbits on the market are water-resistant up to 50 meters (164 feet), and they’ll automatically track your swim lengths, distance, duration, and pace. Additionally, many Fitbits have the ability to connect to your phone’s GPS to provide lap and distance readings. However, certain models on this list, including the Versa 3, Sense 2, and Charge 5, have built-in GPS systems that can track these stats without having your phone with you — making them ideal for open-water swimming.

You can also choose between two designs: a tracker or a smartwatch. Trackers mainly focus on providing health and fitness data, while smartwatches also offer many of the same features as your smartphone — such as sending texts and receiving app alerts — but often come with a higher price tag.

Beyond swim tracking, consider the Fitbit’s full range of capabilities when shopping. For example, most Fitbits offer continuous heart rate monitoring but only certain models, such as the Sense 2 and Charge 5, are compatible with an ECG app that alerts you if there are abnormalities in your heart rhythm. Another nice feature to have is the ability to make and receive Bluetooth calls without having to reach for your phone.

With these considerations in mind, check out the best Fitbits for swimming on Amazon — plus one Fitbit alternative that’s also worth considering.

1. The overall best Fitbit smartwatch

Why it’s great:

• Has a built-in GPS
• Features a built-in mic and speaker for Bluetooth calls
• Compatible with Alexa and Google Assistant

The Fitbit Versa 3 takes the spot for the overall best Fitbit smartwatch for swimming due to its impressive extras, such as a built-in GPS, the ability to receive Bluetooth calls, and enhanced heart rate tracking stats. Like most Fitbits, this water-resistant watch has 24/7 heart rate tracking and an “Active Zone Minutes” feature that gauges your exercise effort based on your resting heart rate, alerting you when you’ve successfully increased the intensity of your workout. However, this model doesn’t provide electrodermal activity (EDA) stress tracking like some other Fitbits and does not have an ECG app and high/low heart rate alerts. But it does come with a six-month free-trial membership to Fitbit Premium, so you’ll have access to advanced health data and other cool features like sleep and daily readiness scores.

One reviewer wrote: “Wear mine all day every day! Love the features and the display screen on this watch! Wear mine swimming, in the shower and during aqua aerobics… no issues! Water proof and fully functional when wet! I use the watch to see text messages and answer calls! Sound is clear and hands are free! Love this watch!”

For a water-resistant smartwatch that has it all, consider this splurge-worthy Fitbit Sense 2.

It can even track your skin temperature and estimate your average blood oxygen saturation (SpO2). The watch will also enable you to receive Bluetooth calls, texts, and notifications and has built-in Alexa for voice commands. Plus, the Sense 2 also features built-in GPS to track activity maps, pace, and distance stats without your phone, as well as an EDA sensor that can detect stress. A six-month trial membership to Fitbit Premium is also included.

One reviewer wrote: “My favorite FitBit so far! Love this watch! It’s interesting to track your sleep, stress levels, body readiness and more. It’s light on the wrist and easy to use. Would definitely buy another one for me or for a gift for someone else.”

However, it’s not compatible with Alexa and Google Assistant for voice commands.

It also has sleep-tracking capabilities and will send call, text, and app notifications from your phone. Additionally, this pick comes with a one-year free trial of Fitbit Premium and has an impressive battery life of 10 days. However, it doesn’t have more advanced features, such as built-in GPS, an ECG app, or an EDA sensor, and it’s not compatible with Alexa and Google Assistant.
