Smartphone apps just as accurate as wearable devices for tracking physical activity 

From the 11 February 2015 Penn State press release

JAMA Paper Among the First to Compare Smartphone App vs. Wearable Device Accuracy

PHILADELPHIA — 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 a new research letter in JAMA. 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. Led by researchers at the Perelman School of Medicine and the Center for Health Incentives and Behavioral Economics at the University of Pennsylvania, this study is a follow-up to a recent JAMA viewpoint suggesting that there’s little evidence that wearable devices alone can change behavior and improve health for those that need it mos

“Since step counts are such an important part of how these devices and apps measure physical activity, including calculating distance or calories burned, their accuracy is key,” said senior author Mitesh S. Patel, MD, MBA, MS, assistant professor of Medicine and Health Care Management at Penn and an attending physician at the Philadelphia VA Medical Center. “Compared to the one to two percent of adults in the U.S. that own a wearable device, more than 65 percent of adults carry a smartphone. Our findings suggest that smartphone apps could prove to be a more widely accessible and affordable way of tracking health behaviors.”
