MetricWire is an easy-to-use platform that allows researchers to design complex studies and provides participants with the option of responding using their smartphones and other electronic devices. With MetricWire, researchers from any industry can gather high quality data on the real-world behaviours of study participants without writing a single line of code. Among the many features of the app is the ability for researchers to passively track your location, both as a recall aide for Time Use surveys, as well as for research purposes. This feature only applies if the researcher enables it for a study you participate in. This feature may be disabled at any time within the app's settings page. Continued use of GPS running in the background can dramatically decrease battery life.
