If enough Americans share daily how they feel, even if they're well, this app can provide the healthcare system with critically valuable information.

This app-based study is a way to find out where the COVID hot spots are, new symptoms to look out for, and might be used as a planning tool to target quarantines, send ventilators and provide real-time data to plan for future outbreaks.
