About our COVID-19 research

Health science company Zoe has developed a COVID-19 Symptom Tracker app with input from King’s College London and Massachusetts General Hospital. The app tracks in real time how the disease progresses. The aim of the app is to help slow the outbreak, by helping researchers identify:

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


The app is available for both TwinsUK members and the general public to use. Participants using the app will record information about their health on a daily basis, including temperature, tiredness and symptoms such as coughing, breathing problems or headaches.
