Fitbit’s activity-tracking wearable devices are already being used by a number of academic institutions to determine if they might be able to contribute to the early detection of COVID-19 and the flu, and now Fitbit itself is launching its own dedicated Fitbit COVID-19 Study, which users can sign up for from within their Fitbit mobile app.

The study will help the company figure out if it can successfully develop an algorithm to accurately detect a COVID-19 infection before the onset of systems. In order to gather the data needed to see if they can do this, Fitbit is asking users in either the U.S. or Canada who have either had or currently have a confirmed case of COVID-19, or flu-like symptoms that might be an indicator of an undiagnosed case, to answer some questions in order to contribute to its research.
