An activity tracker is an electronic device or app that measures and collects data about an individual's movements and physical responses, towards the goal of monitoring and improving their health, fitness, or psychological wellness over time.
Activity trackers are a more sophisticated version of the pedometer; in addition to counting steps, they contain additional sensors such as accelerometers and altimeters to collect or estimate measures including the speed and distance travelled, heart rate, calorie expenditure, or the duration and quality of sleep. Unlike smartwatches, activity trackers tend to be simpler in function and are typically less expensive.
