Fitness Tracker: a high-tech health-monitoring device to wear on your body to enable you to track overall movement, calories burned, sleep patterns, etc.
These devices keep track of your health and fitness goals by constantly reminding you of what you are doing, what you are not doing, and what you should be doing in order to better succeed in your quest to a healthy well-being. Ben Taylor, who writes for TIME, released an excellent article comparing the various fitness trackers in the marketplace.
"Fine. You didn't buy a smartwatch. You were never going to anyway. Meet the fitness tracker: a less expensive, more immediately useful tech product that might actually help get your lazy self in shape."
