So wearable fitness trackers are on your radar, but you haven't figured out if they are right for you. Read on to learn about what it is they do, plus get the lowdown on three popular options.
In general, a fitness tracker's goal is to help you actively monitor your health using the latest and greatest technology.
You wear it -- some must stay on your wrist, others can clip into your clothing or be worn as jewelry -- and it, at minimum, automatically tracks your daily steps, plus distance and calories burned. The tracker then uploads that information to an associated smartphone app, where you can access it, set and track goals, compete with friends, and otherwise use it to better your overall health.
Those are just the basics, however. Additional qualities depend on the tracker you select, and can include physical draws, such as the ability to wear it up to 50 meters underwater or go long periods without charging. Performance perks can include monitoring heart health and waking you up at an optimal point in your sleep cycle.
Here are three popular wearable fitness trackers, and the defining qualities of each.
