If you’re into fitness and love to hit the gym on your weekends, you’ll easily be able to get your hands on a fitness tracker that caters to your favorite activity (such as running) – but that’s not always the case for swimmers. Due to logistics, swimmers can all too often find themselves stuck with limited options due to the fact that electronic devices usually spell a recipe for disaster when paired with water.

With that being said, there are a whole host of manufacturers that create fitness trackers that can take to the water - with Fitbit offering some of the very best! 

If you want to level up your swim workout or performance, you definitely need to pick a Fitbit because not only is it suitable to be used in water, it will also be able to track your performance and help you level up your performance and hit new goals.

Each Fitbit we’ve included in this article is suitable for swimming and each offers their own individual benefits. This means that it can survive soaking, it’s sealed, and has excellent tracking features like pool and open water swim GPS. 

In order to help you get the best value for money, we’ve picked our favorite five Fitbit designs that we’re going to be reviewing to help you get an idea for which might suit your needs the best. As well as this, we’ve also included a buyer’s guide and a F.A.Q section to answer any questions you might have before making a purchase.

If you’re in a hurry and want a great ‘all in one’ that you can put your confidence in, we think that you’ll love the Fitbit Ionic. It’s a lightweight yet durable model that comes complete with  a high res square face that you can use to check your progress while in the water, including the strokes performed, meters swum and your heart rate in order to help you keep track of your performance statistics.

As well as this, its screen is also scratch-proof, which is handy for those moments when you find yourself absent-mindedly swimming into the lane divider on accident or knock it on the edge of the pool as you reach for a drink.

Here’s why it stands apart from the other Fitbits:

  • The watch is rated as waterproof up to 50m which is really impressive considering that most waterproof wearables are typically only waterproof up to 3m.

  • You’ll be able to keep track of your performance data while swimming in order to help you unlock your potential and reach new heights

  • The touch screen is deactivated when you are swimming so that you aren’t getting false results from the watch touching the water while carrying out your laps.

Our Top Pick

Our rating

This is the first-ever smartwatch made by Fitbit! It’s a fitness watch at its heart. It has an aluminum chassis which makes it lighter and robust. The bands are made of plastic and leather. The watch is particularly light, ensuring it is comfortable to wear without weighing you down.

The watch looks mediocre. It has thick bezels on all sides. The LCD display is great for swimmers and is perfect for you to check your progress. It will be able to accurately gather data for your strokes, meters swum, your heart rate and the time. The aluminum frame is very thick and resilient so it can easily take a few knocks here and there. 

Not just for swimming, this fitness-centred smartwatch is also suitable for running, cycling and just about any other type of fitness activity. The heart rate tracker built into the Ionic is one of the best out of all the Fitbit models. It also has an excellent built GPS system which is ideal for pool or open swimming.

The Fitbit Ionic has three gigs of internal storage so that you can store almost three hundred songs on it. Once you have music on your watch, you can pair it with any Bluetooth headset and head to the gym without your mobile.


  • Durable and resilient design
  • Superb battery that can last up to 3-4 days

  • Easy to read LCD display

  • It comes with both small and large sized wrist straps


  • Higher price point

The Fitbit is a simple yet totally resilient model. It is a slim and water-resistant fitness tracker that is always ready to go. It automatically tracks your activity and shows how you slept last night, so it’s ideal for everyday use, too.

When working out, it is able to figure out the exercise and displays the records for you and  a single charge will last for 2-3 days on average. How impressive is that?

You can set your daily goal and the five LEDs will let you know your progress. It can track your laps when swimming and provide basic swim metrics. However, there is no GPS built into this model, which is a factor worth considering if you want to swim in the sea or an open body of water, for example. On the flipside, it does offer heart-rate tracking which is helpful for swimmers to keep track of.

Alongside this, The LED displays can be color-coded for particular notifications while its sleep tracking mode can provide you with information on how well you slept. You can even set an alarm that will wake you up with a small vibration.


  • Great budget option for swimmers
  • Can be used for different types of workouts like running or cycling

  • Neat, smart design


  • A more basic design compared to other Fitbits

The next model on our list is the Fitbit Charge 4! Though the Fitbit Charge 4 looks almost identical to its predecessor (the Charge 3), including the grayscale touchscreen, it comes with a bunch of innovative features that make it great for all types of exercise, including swimming. 

For starters, thanks to the addition of an all new built-in GPS it’s ideal for open water swimming, while its swim metrics mode allows you to track your swims with ease, especially thanks to it being water resistant to 50M. It’s interface is intuitive and easy to read, with only the touchscreen and a discrete button on the left-hand edge as controls. Due to this, you’ll save time in between laps - simply scroll through menus by swiping left and right across the screen to access different options. 

The Fitbit Charge 4 is slim, measuring 35.8mm x 22.7mm x 12.5mm, and so light you'll easily forget you're wearing it! We think this is a real pus when you’re swimming because you won’t feel off balance while stroking.


  • Slim and lightweight design
  • GPS tracker

  • Easy to read display screen


  • Expensive

Next up? The Fitbit Versa 2 Smartwatch. Now, though this Fitbit model is suitable for just about all types of fitness activities including running and cycling, it’s also been designed for swimming! In fact, unlike its predecessor, the Fitbit Versa 2 comes with improved swim metrics and has the ability to count lengths, measure your heart rate and recognise different types of strokes – even those far-from-perfect ones. Plus, thanks to its larger LCD display, your swim metric information is always just a quick glance away.

The length of the pool setting has also been improved. Rather than having to select from pre-programmed options, this feature is now customizable to as little as 10 metres which comes in handy if you find yourself swimming frequently in different sized pools. Alongside this, the Versa 2 will also keep track of your heart rate while in the water.

As well as this, it also comes with a whole host of other cool features! You can control your Spotify app, get calls and texts directly to your smartwatch and even track how well you slept. We think it’s a great choice if you’re looking for a fitness tracker that you can use in everyday life, too.


  • Elegant design
  • Affordable

  • Swim mode that will equip you with information on your swimming performance


  • May not offer enough swim metrics for advanced swimmers

If you’re considering an alternative, a nice option for swimming is the Garmin Vivosmart 4. The great thing about pretty much all Garmin wearables is that they all carry the same waterproof certification. But if you don't fancy one of its sports watches to swim with, you could always opt for the Vivosmart 4 instead.

While generally Garmin's fitness trackers have featured waterproof designs, the Vivosmart 4 is one of the first to actually provide detailed swim metrics. It will only do that in a swimming pool, however, so you won't get that data hit in the open water.

In terms of the data you'll see in the pool, the super slim tracker will auto-track activity offering data but you can manually do it too. From the device you can set pool size and select your skill level. You'll be able to view swim intervals or pool lengths, which is displayed at the top of the touchscreen display.

Your swim data is synced to Garmin's Connect app which can be accessed via your smartphone. In our opinion, the Vivosmart 4 is one of the lightest and slimmest fitness trackers you can take to the water with!


  • Lightweight and slim
  • Superb swim metrics

  • Great value for money


  • Swim data is easier to view via the app, which may be tedious for some users who want to view their data solely from the watch face

Best Fitbit for Swimming - Buyers Guide

Now that you’ve reached the end of this article, we’re hoping that you’ve gained an insight into the different types of Fitbit models available on the market today that are ideal for swimming. 

As more companies create their version of the waterproof fitness tracker for swimming, picking the best device can be difficult. However, there are some standard features to look out for when on the hunt for the best waterproof fitness tracker for swimming. But, if you do still want to take to the internet yourself and compare and contrast your own options, here are some factors to consider:


This is the most important factor when it comes to swimming! You need to ensure that your fitness tracker is going to be waterproof (each model we have included in this review is waterproof). However, if you’re ever unsure, we recommend checking the IP rating of the device you are considering.

The IP rating will indicate the waterproof rating while the ATM shows the pressure it can withstand. We recommend you get a watch with the highest possible IP rating you can afford and one with a high ATM. A lower IP-rated device is easily affected by issues such as rain and sweat. A highly rated device, on the other hand, can withstand the pool and even being rained on.


If you’ve found yourself reading this article, then you’re primarily going to be focused on a model that can offer you swimming metrics. However, you may also find benefit from choosing a device that can be used for all different types of exercise, too! Fitbits are great all-rounders when it comes to fitness and you can use them for just about any type of fitness workout you can imagine (including running, cycling and even hiking). Some of the more expensive models also come equipped with sleep tracking, the ability to take calls and texts from your watch and even to control your music apps.


Whether you are a casual user or a professional, we’re confident you will appreciate accurate data! Whether you’re learning about the distance you swam or wanting to keep an eye on your heart rate during those more intense swim sessions, it’s important that you can have faith that the data you are receiving is correct and accurate. 

For this reason, you will be better able to adjust your workout to meet your goals and figure out your different strengths and weaknesses. 

Battery Life and Charging

Finally, you should always consider the battery life and how long it will take to charge. Luckily for us, most Fitbits will last for a few days when fully charged, which is not only excellent value for money but really helps you to focus on your swimming goals and want you want to accomplish - especially if you find yourself on a swimming trip with limited access to a charger.

Frequently Asked Questions

Why should I have a Fitbit for swimming?

  • It will provide you with swimming data that can help you reach your goals quicker! Whether it’s an interval, a time for a long, unbroken set of straight swimming, or hitting a number of reps swimming a particular time, tracking our swimming gives us measurables to track and compare that will all help you reach your goals quicker.
  • It will give you motivation in the water. This is really important in our opinion, particularly for swimmers who train on their own and need a little extra ‘oomph’ sometimes to complete their workout. Having results of your swim workout right in front of you will push you to train a little harder, while also giving you the satisfaction of knowing that you accomplished something measurable in the water that day. It’s almost like you have a mini personal trainer on your wrist!
  • Keeps you disciplined. With the addition of a Fitbit or fitness tracker, you’ll be provided with metrics on your laps that will inspire you to go the extra distance. 
  • Helps plan your training around your different strengths and weaknesses. No matter whether you’re swimming for fun or for a competition, it’s always helpful to have information on your swimming performance, even if it’s just out of curiosity! It’s helpful to know where you are at so that you can better plan your training sessions to help you accomplish your goals and take your swimming level up a notch.

Do I have to be a good swimmer to use a Fitbit device?

No, not at all! Your Fitbit device records your swims even if you’re a novice swimmer, meaning you can swim about 6 to 12 lengths of the pool without stopping to rest. If you’re unable to swim this distance, you may notice inconsistencies in your swim data including some lengths not counted, but as your swimming endurance improves you’ll notice more accuracy.
