Let's Recruit 1M People! Join COVID-19 Citizen Science Study

We invite every adult with a smartphone to combat the COVID-19 pandemic by contributing their data for science! Please join the COVID-19 Citizen Science Study, a fully remote, mobile-app based study developed and run by UCSF investigators. You can text COVID to 41411 or download the app (note: you must access this website using a computer; entering your phone number will send a download link to your smartphone). We encourage everyone to spread the word, as UCSF researchers hope to enroll at least a million people from all over the world.
