Who is this app for?

This app is for people who have had COVID-19 (with or without a positive COVID-19 test) and have symptoms that last more than four weeks, including:

  • adults
  • young people
  • children.

It may also be helpful for:

  • parents of children who have had COVID-19
  • other family members, partners, friends and carers.


What is this app about?

This app is based on a patient information booklet which explains the recommendations in a guideline produced by the National Institute for Health and Care Excellence (NICE), the Royal College of General Practitioners (RCGP) and the Scottish Intercollegiate Guidelines Network (SIGN) on managing the long-term effects of COVID-19..

The app explains:

  • common symptoms of long COVID
  • how you would be assessed if you have new or ongoing symptoms after having COVID-19
  • tests that may be part of your assessment
  • how your care will be planned and who will be involved in your care
  • what can help
  • where you can find more information about your recovery
  • how you will be followed up.

Long COVID is a new illness that healthcare professionals are still learning about. Most of the recommendations are based on the experience and expert knowledge of healthcare professionals. Research is taking place and the guidance may change when its results are known.

NICE, RCGP and SIGN are developing the guideline using a ‘living’ approach, which means that the guideline will be reviewed and updated when new research comes out. The patient information booklet and this app will be updated at the same time.


This app has been developed by the SIGN (Scottish Intercollegiate Guidelines Network) team within Healthcare Improvement Scotland, in collaboration with the Digital Health & Care Innovation Centre (DHI). 

Special thanks are due to the NHS Greater Glasgow and Clyde Knowledge Services team, who provided knowledge management support in creating the app structure and adding the content.

SIGN and DHI would also like to thank the people with lived experience of long COVID who advised on the design and content of this app.
