You must also know that buying a waterproof fitness tracker does not mean that it can be used to track your swimming activities.

For example, Fitbit Ace is a waterproof wearable device, but you cannot swim with Fitbit Ace as it is not designed for swimming. 

What Fitness Trackers Measures While you swim?

Five metrics assess the quality of swim. If you are looking for a smartwatch that measures all these five metrics, then you have to get an advanced smartwatch. But unless you are not a professional swimmer, then you do not need such an advanced swim tracking smartwatch.

Before you jump into the list of swim watch, let us have a look into these five crucial swim metrics.

  • Speed: It is an essential metric that is tracked by every swim-proof smartwatches and fitness trackers. It uses a sensor called an accelerometer to measure the pace in the pool or open water.
  • Distance: Distance is another vital swim metrics measured by a swim watch. Most of the fitness trackers and smartwatches are calibrated for  25M and 50M pools. On the other hand, some models of  Fitbit Trackers allow us to enter pool length manually. These Fitness trackers are suitable for closed water or pool swimming only.

    If you want to track open water or sea swimming, then you must go for an advanced smartwatch for swimming with an in-built GPS. Obviously, it will cost you more money. Make sure you enter the distance correctly to avoid any error in tracking lap and speed.
  • Stoke Count: As the name suggests, stroke count is the number of strokes that you take to cover a particular distance. It is an important metric to measure your performance in the water.
  • Type of Stroke: It is an advanced feature available only in premium swimming watches. It measures the type of stroke that you have taken in the water. You should not bother about this if you are not preparing for a swimming competition. 

    Freestyle stroke, Backstroke, Breaststroke, Butterfly stroke, and Sidestroke are the different types of strokes for swimming.
  • SWOLF: It is a calculated metric measured by calculating the stroke count per distance. It is also called as Swim Golf.

    A SWOLF score of 35-45 in a 25m distance is considered as excellent, and any score above 50 means that you need more improvement.

    It is also an advanced feature and does not need to measure this if you are not a professional swimmer.

Swimming Watch Buying Guide

So we have already discussed the best fitness tracker and smartwatches for swimming. If you are still confused, then please refer to this fitness tracker buying guide to choose one of the best smartwatches for swimming.

First of all, I want to ask you a question. It is nothing but important. Here is my question.

Why do you want to buy a fitness tracker for swimming? Is it just for fun, or are you a professional swimmer or preparing for a swimming competition?

If your answer is just for fun, then you do not need to invest more money into an advanced smartwatch. For you, basic features such as lap, speed, distance, and stroke count are enough. And obviously, calorie tracking is essential for you too, and all smartwatches have this feature.

Moov Now, Fitbit Versa 2, etc. would be a better choice for you. If you have a little more budget, then you can go for multi-tasking watches such as Apple Watch or Garmin Series. You can go for the Garmin Forerunner series if you are a professional runner and also like water-based activities.

Now, if you are a professional swimmer and need to track every activity in the water, then you must need an advanced Smartwatch like Garmin Swim 2 or Apple Watch 5 Series.

Make sure you choose an advanced swim watch that tracks lap count, distance, pace, stroke count, stroke style, SWOLF, and also calorie tracking.

You can become a better swimmer by improving these metrics for sure. After you swim, go to the companion app to get more detailed data about your swim and discuss it with your swimming coach to identify the area of improvement.

Advanced swim watches also have the features to set new goals based on the previous data and help you to keep motivated and break new records in the pool.

Now let us other features that you should take care of while choosing a fitness tracker for swimming.


Always go for a smartwatch with a sleek design and light-weight. Because it will be more comfortable while swimming rather than using a bulky smartwatch during the swim.


You should also take care of display while selecting a smartwatch. If you are looking for a smartwatch for water-based sports, then make sure that it has a brighter screen so that you can see your metrics even underwater.

Some advanced smartwatch like Apple Series 5 watch offers a screen lock feature, which helps to avoid any unnecessary tap on the screen when it comes in contact with water. In Apple Watch Series 5, this feature automatically turns on when you activate the swimming mode.


Make sure that the Smartwatch which you are going to buy is compatible with the smartphone that you are using. Also, make sure that the companion app is compatible with your smartphone. You possibly do not face an issue of you are using an advanced latest fitness tracker.

However, these app and device compatibility checks help you to save your hard-earned money.

Heart Rate Monitoring

Even advanced smartwatches do not track heart rate accurately underwater. Most of the watch automatically turns off the heart rate monitor at the moment you turn on the swimming mode.

If you want heart rate monitoring while swimming, previously, it was expensive. Thank you, Garmin, for crafting Garmin Swim 2! It is the only watch that tracks heart rate underwater by using its advanced heart rate sensors.

Before that, you had to use HRM-Tri or HRM-Swim heart rate monitor along with your compatible Garmin Smartwatch.

SUUNTO Spartan Trainer also can track heart rate in water. But it is not accurate as Garmin Swim 2 watch.

Battery Life

Battery life is vital for any electronic gadget. I prefer a smartwatch with longer battery life rather than choosing a smartwatch with a lot of features and less battery back-up.

By keeping this in mind, I created this list with devices with good battery life.


I think this Fitness Tracker review has helped you to choose the best fitness tracker or Smartwatch for swimming. All the fitness trackers and fitness trackers listed here can track not only the swimming activity but also can track many activities such as running, heart rate monitoring, calorie tracking, etc.

If you have any queries or if you feel to add more smartwatches into the list, then feel free to comment below. You can also contact us through our social media channels for an instant replay.
