Covid Symptoms Study

The ZOE COVID 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 4.7 million contributors globally, the Study is the world’s largest ongoing study of COVID-19 and is led by ZOE Co-Founder, Tim Spector.

Design & Build as part of ZOE team

The story

In March 2020, Tim Spector, a genetic epidemiology professor at King's College London and a co-founder of ZOE proposed to build a tool to help with the research of new coronavirus spreading around the world. Initially, the goal was to create an internal tool for ZOE research participants to report & study the symptoms of Covid-19. Towards the end of the development cycle, (5 days, which is exceptionally fast for any digital product release), we've made a decision to pivot away from internal testers & release the app publicly to maximize the learnings from incoming data.
By the end of day 1, the app was going viral on social networks and was downloaded over 1 million times. The story was picked up by all major news outlets and online publications. To date, there are over 65K press articles covering this product. The Covid Symptoms Study app was ranked number 1 on App Store and Google Play Store list of most downloaded health apps in the UK.  

The project received support from the UK Department of Health & UK government. It is endorsed by NHS Wales and NHS Scotland. The app was later extended to cover US and Sweden territories. All data is analysed by a joint team from ZOE and King’s College London.
