COVID Symptom Tracker

By downloading and using the 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.

Take 1-minute to self-report daily, even if you are well.

Help their scientists identify:

  • High-risk areas in the UK.
  • Who is most at risk, by better understanding symptoms linked to underlying health conditions.
  • How fast the virus is spreading in our area.
