How Do Fitness Trackers Track Steps

Fitness trackers have grown in popularity in the last five years. Today, around one in five U.S. adults say they often use a wearable fitness tracker or smartwatch to count their steps. How do fitness trackers track steps? Are they accurate? What are the benefits of wearing these devices, and are they affordable? Let’s take a look.

What is a Fitness Tracker?

There are dozens of fitness trackers on the market today. These devices have exploded in popularity as tools to help people lose weight, stay fit, or simply get moving during a sedentary lifestyle.  PC Magazine defines fitness trackers as “A wrist-worn device that can detect some combination of walking steps, running distance, heart rate, sleep patterns, and swimming laps.” But this definition is slightly incorrect; today, we have fitness tracking devices that can be worn on your finger, like the Motiv ring. New devices are being created all the time, like the Fitbit Zip that clips to your clothing.
