Although wearable devices have received significant attention for their ability to track an individual’s physical activity, most smartphone applications are just as accurate, according to new research. The study tested 10 of the top-selling smartphone apps and devices in the United States by having 14 participants walk on a treadmill for 500 and 1,500 steps, each twice (for a total of 56 trials), and then recording their step counts.
