Covid-19 Symptom Tracker

We Want to Know...

The COVID-19 Symptom Tracker is a novel app for mobile devices designed to specifically capture self-reported information regarding symptoms associated with COVID-19 during the current COVID-19 pandemic. These data will help us better track how and how fast the virus is spread. It will give us critically valuable information about 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.

The COVID-19 Symptom Tracker has been developed by Zoe Global, Ltd in collaboration with Dr. Timothy Spector, at King’s College in London. All data are for non-commercial purposes to help fight the COVID-19 pandemic. The app is currently in use in the UK, and we would like to extend participation to the US.

Eligible Participants

All adults (18 years or older) are invited to use the COVID-19 Symptom Tracker.
