About COVID Symptom Study

1. In the US the app is being used by the Nurses' Health Study to identify symptoms in active healthcare workers who are treating people with COVID across the country and risking their own health to help us.

2. You will contribute to advance research on COVID-19 in partnership with leading health researchers globally like TwinsUK, one of the most clinically detailed studies in the world.

3. This app (formerly known as the Covid Symptom Tracker) allows you to help others, but does not give health advice.

4. It was designed by doctors and scientists at King's College London, Guys and St Thomas’ Hospitals and Zoe Global Limited, a health technology company.

5. With your help we can understand better how the disease presents itself depending upon individual factors such as health and age.

6. With your help we can understand much better the situation across the nation, how the disease presents itself to different people, and how it progresses.

7. You will be asked to share some general information, such as your age and some health details, such as whether you have certain diseases.

8. In response to recommendations by Stand Up To Cancer (SU2C), the app also includes questions for cancer patients and survivors, such as if they are living with cancer, what type of cancer and what treatment they are receiving.

9. There are a wide range of symptoms, which differ between people.

10. No information you share will be used for commercial purposes.

11. We will ask you every day to let us know how you feel, so you can share your symptoms.

COVID Symptom Study Customer Insights

1. I'm going to have to uninstall because the daily notifications are just frustrating if I can't then report.Overall, a very good app and excellent that scientists are using this app to honestly gather information that can help safely end this pandemic sooner! That (and to a significantly lesser extent, the clean visual design) is what the five stars are for.

2. After finishing the process in spite of known errors/omissions I'vr not found any way to correct or edit my profile after registered.The app has always been easy to use, and the latest update seems to successfully fix crashes in it.

3. On an 8GB phone, that’s quite a lot of the available storage! Could it be made less space-hungry please? Since late 2022 the UI has been incredibly slow to use, taking 5s to respond to touch input.

4. I have notifications allowed on my phone, but it appears the app is not sending them.This app could use some improvements in these areas: After having logged a day's symptoms, there is no go to the main menu, save and quit type option.

5. Keep up the good work and wear a mask!!!The initial install was a little confusing as it looked like the install(android) didn't work, however it is just the way the app appears.

6. Might be a valuable dataset for diagnosing people at home.Update July 2022: reminders have disappeared again.

7. This leads to my 2nd suggestion, it's logging my responses somewhere...cant there be a screen that shows my responses? Id be much more interested in continuing this, if i could see a record of my general health.

8. Please fix this!I've been participating for two years now but my new Pixel 6 freezes on the splash screen after I click the notification.

9. I live in Sweden but am not a fluent Swedish speaker, which means I'm either spending a lot of time looking up words or taking educated guesses.

10. More...Recommended by California Teachers Study, in which I've been a participant for at least a decade.

11. My only real feedback is that the location appears to determine the language and that makes the app less accessible.
