Help slow the spread of COVID-19 by self-reporting your symptoms daily, even if you feel well.
Join millions of people supporting scientists at King’s College London to help our health services by identifying:
* How fast the virus is spreading in your area
* High-risk areas in the UK
* Who is most at risk, by better understanding symptoms linked to underlying health conditions
You will contribute to advance research on COVID-19 in partnership with leading scientific institutions like King’s College London and TwinsUK, one of the most clinically detailed studies in the world.
This app (formerly known as the Covid Symptom Tracker) allows you to help others, but does not give health advice. If you need health advice please visit the NHS website at: https://www.nhs.uk/conditions/coronavirus-covid-19/
This app is designed by doctors and scientists at King's College London, Guys and St Thomas’ Hospitals and Zoe Global Limited, a health technology company.
If you would like to help out in this difficult time, then you can. Download the app and share daily your own status, even if you are well. With your help we can understand much better the situation up and down the country, how the disease presents itself to different people, and how it progresses.
This is a new virus which the UK has never seen before. There are a wide range of symptoms, which differ between people. With your help we can understand better how the disease presents itself depending upon individual factors such as health and age.
No information you share will be used for commercial purposes.
There are two parts to the app:
You will be asked to share some general information, such as your age and some health information, such as whether you have certain diseases.
We will ask you every day to let us know how you feel, so you can share your symptoms. We will also ask whether you have visited the hospital, what treatment you received there, and whether you have been tested for COVID-19 (Coronavirus).

Great to help sort fact from fiction
My only problem is that I went down with Covid on 20th March when tests were only available for Clinical Staff in hospitals. The 111 doctor who phoned me back thought I had Covid because 2days before I went down with it a paper in the American Journal of Gastroenterology from Wuhan had said that in a third of patients the presenting symptoms was diarrhoea. I had this and a high temperature and two days later the cough started and the loss of taste, dreadful headaches and a hoarse voice. Although I was quite poorly for 2weeks I did not get breathless enough to require hospital admission. My decision as I had worked in respiratory disease in Pharma for 40 + years and my late husband was a chest physician. Two months after this I spent a day in our local hospital with a diagnosis on CT scan of non Covid pneumonia. I honestly believe I had Covid as I have had post viral muscle fatigue and it has affected my brain. I should have an antibody test but that may prove negative as reports from Wuhan indicate that only those requiring hospital treatment continue to produce antibodies after 2 to 3 months. Catch 22!
Great idea but a little flawed.
I find the idea of this app fantastic! It will be extremely helpful in tackling this disease and documenting lots of data. My main issue and area for suggestion is for the questions relating to whether you think you have had it. I myself believe my partner and I have had Covid-19 but despite me coming into possible contact with the disease I was not deemed ‘high risk’ by NHS 111 and was therefore not tested. This is where I think the app falls short of being incredibly helpful to scientists and data analysts. Where you ask ‘do you think you have had Covid-19?’ You should then ask what symptoms the person had, how long they lasted for, had they come into potential contact with someone with Covid-19 and how long before symptoms started presenting, and ask for a quick diary of events and a summary as to why they think they had it. The reason for this is you will get a better picture of incubation time, access fully the extent of how many were a 90%+ sure they had it, how many it may have been a cold, and based on age range, location, underlying illness you can find out survival statistics, severity of symptoms and get a rough idea of possible herd immunity going on. Basically your data would be more thorough, extensive and she’s better light on this disease which may be useful to the NHS, scientists and government. With all that said I still encourage people to use this app and keep up to date with how they feel in these uncertain times!
Further questioning needed
A great idea and in theory would be great to help and offer insight but as many have commented already, it would be useful to ask whether anyone has already had any symptoms, how long for and have options to add in extra information besides just ticking boxes.
I am currently on day 20 of feeling ill, having been through cold symptoms which got better to flu symptoms within about 5 days which lasted approx 3-4 days to a delaying congestion and headache, reoccuring sore throat and cold like symptoms again and had other symptoms not listed in your options given.
Also although I understand your medical 'questionnaire' asks these particular questions to reach desired data collected some of the questions didn't allow but just yes or no answers and there may be more to a person's circumstances like the questions if you have particular conditions like kidney failure, no but I have one kidney, have you been to hospital no but spoke to a gp who suspects i have covid 19, have you been tested no because my symptoms weren't urgent enough.. Some widening of your questions and more options and / or free text boxes for answers may give you a lot more insight into people's actual experiences with or without symptoms. Equally though, I hope whatever you do manage to collect serves some purpose to help understand this virus better to be able to find ways to beat it.
