A thorough yet straightforward review on the best waterproof fitness tracker of 2021

Are you a swimming athlete? Or are you just a regular jogger? Either way, you might want a fitness tracker to keep up your game and track your health condition every time you workout. If that’s the case, then you are in the right place. In this article, you will find a list of the best waterproof fitness trackers of 2021.

What is a Fitness Tracker?

Before getting to the list, it might also be good to know what a fitness tracker is. To simply put, a fitness tracker is a wearable device similar to a watch. But, the technology difference is this device can not only track time but also monitor and track your physical fitness, such as your heartbeat, blood pressure, calories, length of workout time, etc.

The Advantages of Having a Fitness Tracker

With the many features of a fitness tracker, there are some advantages you can get by wearing one, such as:

  • Maintain your healthy habits – Establishing a healthy habit can be very difficult. Maintaining one will need a lot more effort in the long run. The fitness tracker will help you stay motivated and make sure to keep you on that healthy lifestyle.
  • A Universal Fitness Tool – Equipped with an accelerometer, a fitness tracker can measure many fitness-related activities, such as burning calories, counting steps, measuring heart rate, etc.
  • Monitor Your Sleep – A good night’s sleep helps you be more productive the next day. Hence, the fitness tracker monitors your sleep routine to enhance your sleep quality.
  • In Line With Your Fashion – The design of fitness trackers is similar to a bracelet. They are thin and light and often come in several choices of colors so you can match them with your outfit.

Now all of those advantages would be useless if the device itself can’t keep up with the weather. In addition to the advantages, a waterproof feature is also equally important. So that you can still monitor your progress underwater or even under the rain.

The following three waterproof fitness trackers featured in this article will be equipped with several key features, such as:

  • High Accuracy Measurement – Measuring walking steps, monitoring heart rate, counting calories burned, and tracking sleep routine.
  • Swimproof – Usable underwater and on rainy days.
  • Long battery life – Up to 7-15 days of daily usage and fast-charged.
  • Bluetooth sync – Compatible with iOS and Android devices.
  • Stylish – Slim and comfortable design, compete ably with smartwatches.

These features are the most important things to consider when buying a fitness tracker. With that in mind, let’s get into the list.
