COVID-19 Symptom Tracker App

Posted on: Thursday 16 April 2020

The Welsh Government and NHS Wales are appealing to the Welsh public to download a new COVID Symptom Tracker app to help the NHS response to COVID-19 in Wales.

The app is available to download from the Apple App Store and Google Play from the links at

People across Wales are being asked to log their daily symptoms to help build a clearer picture of how the virus is affecting people. The app is for everyone, not just those who are experiencing symptoms.

Developed by researchers at King’s College London and healthcare science company, ZOE, the COVID-19 Symptom Tracker is already being used by more than 38,000 people in Wales, and over 2 million across the UK. People are using the app to track their daily health and any potential COVID-19 symptoms. It is also being used by healthcare and hospital workers.

Data from the COVID-19 Symptom Tracker app will be shared daily with the Welsh Government and NHS Wales.

Scientists from Kings College London and the Secure Anonymised Information Linkage (SAIL) Databank at Swansea University will work with the Welsh Government to analyse the data to inform modelling and understand and predict the developing situation of the disease in Wales and give early indications of where future hospital admissions are going to be.

The research team at King’s College London and ZOE are also analysing the data to generate new insights about the disease.

An interactive map allowing anyone to see the distribution of COVID in their area is available at as well as frequent science updates.
