In a recent paper by Drs. Dominick, Winfree, Pohlig, and Papas, we asked the question of “What is the accuracy of that Fitbit in an ecologically valid setting?”

Wearable activity monitors such as Fitbit enable users to track various attributes of their physical activity (PA) over time and have the potential to be used in research to promote and measure PA behavior. However, the measurement accuracy of Fitbit in absolute free-living conditions is largely unknown.
