About this app

Help critical research into major health conditions by reporting how you feel each day in the app, even if you feel well.

Join over 800,000 people in supporting scientists to help our national health services fight the biggest health issues of our generation. Millions joined ZOE to fight COVID-19 with their mobile phones from home. Why stop there?

The ZOE Health Study is an evolution of the ZOE COVID Study, which has data quoted in thousands of news stories and published in dozens of scientific papers. We’ve already proven that our approach can rapidly advance scientific understanding and public knowledge.

With our technology and dedicated Contributors, our research will look at how altering your day-to-day behaviour could impact your immune system and reduce the risk of developing major diseases from cancer to dementia. You will be directly helping us to develop an early warning system for disease detection which will help to save lives.

This app (formerly known as the ZOE COVID Study) allows you to help others but does not give health advice. If you need health advice please visit the NHS website.

DATA

The data that you give us for our research into diseases other than COVID-19 will be restricted to King’s College London and ZOE only unless you opt-in to share it more widely in the future.

Your data is protected under GDPR, and can only be used for the purpose that you consent to.

We’ll never sell your data and we’ll be transparent about developments we make to products that advance human health. Please read our privacy policy for more information.

HEALTH INFORMATION

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

DAILY SYMPTOM TRACKING

We will ask you to set up your ‘Usual Self’, this is your personal health baseline and will indicate any symptoms you may frequently suffer from. By telling us how you feel each day and reporting any changes in your usual symptoms, we will be able to relay valuable data to scientists.

ADDITIONAL RESEARCH STUDIES

We’ll conduct voluntary participant studies to see how lifestyle changes might work for you as individuals. We’ll play back insights from the studies to the community that will enable you to live your healthiest life and reduce your risk of developing major diseases.

In-depth studies into issues such as menopause and cancer will uncover detailed new findings to advance our understanding of major conditions and diseases. This app is designed and built by ZOE Global Limited, a health science start-up, in partnership with doctors and scientists at King's College London.

Update July 2022: reminders have disappeared again. Update 22 December: reminders have disappeared again. I have been using this app since it was released. The update caused two problems. One is having to relog into the app, with which some reviewers are having problems. The second glitch is the loss of reminder notifications. I have notifications allowed on my phone, but it appears the app is not sending them.

Currently i.e. this morning the app won't open up and get the message 'COVID Symptom Study keeps stopping' and 'close app' and 'send feedback' - Have tried several times and get the same message, and have sent feedback twice. The problem persists as I daily try to start the app, it stops and I send feedback. I tried again yesterday (July 3rd) and it worked, and again earlier today.

Mostly great. My only real feedback is that the location appears to determine the language and that makes the app less accessible. 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. It would be better if users could select from several languages. This would also increase data from vulnerable demographics.
