The information you give us is essential to understand COVID-19. We take the trust you've granted us very seriously and have rigorous steps in place to ensure your information is secure. This is why public health and other authorities are working with us. We are also working hard to improve the app based on your feedback. This is a non-profit initiative so please bear with us.
By using this app you're contributing to advance vital research on COVID-19. The app will be used to study the symptoms of the virus and track how it spreads.
This research is led by Dr Tim Spector, professor of genetic epidemiology at King’s College London and director of TwinsUK a scientific study of 15,000 identical and non-identical twins, which has been running for nearly three decades.
The COVID Symptom Tracker was designed by doctors and scientists at King's College London, Guys and St Thomas’ Hospitals working in partnership with ZOE Global Ltd – a health science company.
