Best Activity Tracker Buying Guide

Last Updated on September 12, 2021 by Karen Maldonado

What does an activity tracker do?

Activity trackers come in many styles and can improve your overall wellness by tracking your exercise activity, fitness levels, sleep, and calorie consumption. By understanding these trends, users can monitor and adjust behaviors that influence overall health and well-being.


How does it work?

Most activity trackers monitor every detail of your day with sophisticated motion sensors. Activity trackers can automatically sync your information to PCs, Macs, and select Bluetooth Smart Ready devices. Depending on the model, sensors will detect walking, twitches during sleep, and even heart rate. Data from these events is transmitted to a smartphone or computer via a Bluetooth or Wi-Fi connection. Whether you’re interested in your sleep quality or the number of calories burned canoeing, data from these events is literally at your fingertips with the tracker’s companion smartphone app.


How is an activity tracker different from a smart watch?

Although, in some instances, both devices can tell time, activity trackers are primarily dedicated to monitoring biometric data and physical activity. Smart watches leap beyond fitness, enabling users to check email, answer calls, and much more. Besides differences in function, activity trackers come in different forms; some of which include bands, necklaces, and inserts.


What about compatibility?

Customers should consider two factors before making a purchase: operating system (OS) and Bluetooth version. Typically, activity trackers are designed to work with a specific OS, such as Android or Apple iOS. Selecting a tracker compatible with both operating systems is wise if you’re undecided about your future smartphone. Additionally, certain trackers are only compatible with a particular version of Bluetooth. You can learn more about compatibility in the “Product Features and Technical Details” section of each product page.
