What is a Fitness Tracker?

A fitness tracker is a device, mostly in the size and shape of a watch that you can similarly wear on your wrist. What makes it different from a standard watch is that it has a plethora of other functions, primarily for convenience when it comes to monitoring and tracking fitness and health. Thus, these can be called a ‘fitness watch’ in a way too.


How to set up a Fitness Tracker?

The Setup system differs from brand to brand, but overall is a simple three-step system.

  • To set up your Fitness Tracker you will have to download a companion app that will connect to your watch through pairing.
  • Most apps require you to Sign-Up or create an account before you proceed.
  • They will additionally ask for your health and fitness details to provide you with accurate tracking.
  • Once set up and linked with your smartphone you can monitor your stats and even customize your Fitness Tracker.


10 Key Features to look out for in a Fitness Tracker

A fitness tracker or a fitness watch should ideally be versatile and ideally possess most of these features

  1. Heart rate monitor: To measure the heart rate during your rest and active state.
  2. OS friendly: A fitness tracker should ideally be able to connect with the OS you are using through a companion app.
  3. Respiratory monitor: Useful for people and professionals with respiratory issues.
  4. GPS: Very useful for long-distance walking, jogging and running. Great tool for setting a virtual track in terms of distance to cover.
  5. Calorie Tracking: Helps you to average out daily burnt calories to plan your exercise and diet better.
  6. Sleep tracking: Sleep is vital for good health. A proper sleep tracker lets one know the duration of the REM cycle and sleep quality.
  7. Workout Reminder: Helps you schedule your daily exercise.
  8. Silent alarm: A vibrational alarm would be much better than a loud sound that disturbs others.
  9. Movement reminders: Sitting still and working for too long isn’t good for health. Remembering to move will help you maintain better health.
  10. Support for swimming: Most trackers are just sweatproof, but the ones designed for swimming are also water-resistant LCD. Ensure that you choose per your functionality.

How to choose a Fitness Tracker?

Choosing a fitness tracker from an ocean of options can be overwhelming. To narrow down the options, look for one that supports your lifestyle.

If you’re a sportsperson, a sport-oriented multi-functional fitness tracker would be fantastic. If you just want a device for monitoring, a less expensive version would suffice. If you’re adventurous and like to explore, one with GPS functionality would be desirable.

It can come in price ranges as low as under $200, all the way to above $500. Sometimes more. Keep your budget in mind before choosing one.

With that being said, we’ve done some homework for you. Here’s a list of 10 excellent fitness trackers when it comes to combining functionality, quality, and value. The list is in no specific order as each one has its perks and downsides. So have a look and choose wisely!
