Do fitness trackers really help people move more?

Physical activity monitors, such as smart watches and fitness trackers, may help people get more exercise, such as extra daily steps and more moderate-to-vigorous activity per week. But the long-term durability of this behavior change is unknown. Using a fitness tracker requires more than just moving more; people also have to remember to keep the tracker charged, wear it consistently, and check their data. But for some people, the day-to-day feedback on their progress may help keep them engaged.
