You can help the NHS build a better understanding of Coronavirus with just one minute of your time each day.

All you need to do is download the new COVID Symptom Tracker app and use it each day to report your health. Using the app to log your daily symptoms will help build a clearer picture of how the virus is affecting people. The app is for everyone, not just those who are experiencing symptoms.


First Minister, Mark Drakeford, and NHS Wales are appealing to the Welsh public to download the new app to help the NHS respond to COVID-19 in Wales.

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. It will give early indications of where future hospital admissions are going to be.

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.

Cllr Mark Pritchard, Leader of Wrexham County Borough Council, said: “I would urge everyone who is able to download this app to do so. It is free and using it will mean that NHS Wales will have a clearer picture of how fast the virus is spreading and where the hotspots are.”

Ian Bancroft, Chief Executive of Wrexham County Borough Council, said: “Building a picture of how the virus is developing in the local area is important for our service delivery and those who are delivering that service. If you want to help during this difficult time, this is one way that you can.”

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

First Minister, Mark Drakeford said: “Having a range of evidence and data is crucial in helping us build a clear picture of how the virus is behaving and affecting everyone’s lives. Crucially this app can help us anticipate potential COVID hot spots and get our NHS services ready. I’m asking everyone in Wales to download the new COVID Symptom Tracker app, so you can help protect our workers and save lives. Together we can build the best scientific picture so we are better armed to fight this terrible disease.

“The research team at King’s College London and ZOE are 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.”

Lead researcher Professor Tim Spector from King’s College London, says: “Accurate real-time data is essential if we are to beat this disease. Without accurate and wide spread testing it’s essential that we have much data as possible to help us predict where we are going to see the next spikes in demand so that resources can be effectively deployed ahead of time to meet the needs of the patients. The support of the Welsh Government and NHS Wales is an incredibly positive step in the right direction and we hope to see other NHS groups coming on board in the coming days.

“We would like to take this opportunity to thank every single person who is already participating, and would urge everyone else to download the app and check in every day, whether you are experiencing any symptoms or feeling fine.”
