Increased physical activity facilitated by these devices could lead to clinical benefits not realized by low adoption of pedometers.

Results should be confirmed in other settings and with other devices. Our study is limited by being conducted with young, healthy volunteers in a controlled setting with a convenience sample of a small number of applications and devices. Underlying differences in device accuracy may be compounded in these measures. Step counts are often used to derive other measures of physical activity, such as distance or calories burned. Wearable devices differed more and 1 device reported step counts more than 20% lower than observed. Data from smartphones were only slightly different than observed step counts, but could be higher or lower. We found that many smartphone applications and wearable devices were accurate for tracking step counts. The mean step count and standard deviation for each device was estimated using Excel (Microsoft). In rare instances that a device was not properly set to record steps (8 of 560 observations), these data were not included. In the other pants pocket, each carried the Galaxy S4 (Samsung Electronics) running 1 Android application: Moves (ProtoGeo Oy).Īt the end of each trial, step counts from each device were recorded. In one pants pocket, each carried an iPhone 5s (Apple) simultaneously running 3 iOS applications: Fitbit (Fitbit), Health Mate (Withings), and Moves (ProtoGeo Oy).

On the wrist, each wore 3 wearable devices: the Flex (Fitbit), the UP24 (Jawbone), and the Fuelband (Nike). On the waistband, each participant wore the Digi-Walker SW-200 pedometer (Yamax), which has been well validated for research, 6 and 2 accelerometers: the Zip and One (Fitbit). This study was approved by the University of Pennsylvania institutional review board.Ī convenience sample of 10 applications and devices was selected from among the top sellers in the United States. An observer (M.A.C.) counted steps using a tally counter in August 2014. Participants gave verbal informed consent to walk on a treadmill set at 3.0 mph for 5 steps, each twice, for no compensation. This prospective study recruited healthy adults aged 18 years or older through direct verbal outreach at a university. Shared Decision Making and Communication.
