The COVID Symptom Study app is a not-for-profit initiative that was launched at the end of March 2020 to support vital COVID-19 research. The app was launched by health science company ZOE with scientific analysis provided by King’s College London. With over 4 million contributors globally, the Study is the world’s largest ongoing study of COVID-19 and is led by ZOE Co-Founder and King’s College Professor, Tim Spector.
By using this app you're helping and contributing to advance vital research on COVID-19. By combining your reports with software algorithms, we are able to predict who has the virus and so track COVID infections across the UK and now other countries (see COVID Data). Your daily reporting is also being used to generate new scientific understanding of the very different symptoms the virus causes in different people. We are also studying the way that risks vary between individuals because of their own personal characteristics. Visit the News and Research section to read about the research, listen to webinars, and read the academic papers that are being produced entirely because of your contributions.
