The Covid Symptom Tracker App is available via https://covid.joinzoe.com/. It provides a way for everyone to contribute to research to better understand symptoms and the spread of COVID-19.

The App has been designed by a genetic epidemiologist at King's College London and researchers from St Guy's and St Thomas' Hospital and is supported by the National Institute for Health Research. Please sign up if you can and spend about 1 minute per day updating your data and to help tackle this virus.
