+title: Get help while using the NHS App 
+description: Use the app help button to let users access help information while they use the NHS App.  
+backlogID: 447
+tags:
+  - helpUsers
+---
+
+This helps users overcome problems they experience in the app without having to contact their GP or the app support team.
+
+![The top navigation menu. The NHS logo is on the left and a button with the text app help is on the right.](/assets/images/top-navigation-2026.png)
+
+## When to use
+
+The button is part of the [top navigation]([../components/top-navigation) menu. It can be accessed from almost every screen of the app.
+
+When a user is accessing NHS App services through a web browser, the help button is part of the persistent [header (web)](../components/header-web) menu.
+
+## How to use
+
+Use the button to open a help page hosted on the NHS website. In the mobile app the page opens in a web browser overlay.
+

+
+This overlay pattern is being reviewed. We are looking to [improve how NHS website and third-party pages open from the app](https://github.com/nhsuk/nhsapp-frontend/issues/450).
+
+In the web browser version of the NHS App, help pages open in a new browser tab.
+
+### Which page to open
+
+Take users to a help topic menu page that's relevant to where they are in the app. For example, [Help with prescriptions in the NHS App](https://www.nhs.uk/nhs-app/help/prescriptions/) or [Help with appointments in the NHS App](https://www.nhs.uk/nhs-app/help/appointments/).
+
+If there is not a relevant topic menu page, take users to the main [Help with using the NHS App](https://www.nhs.uk/nhs-app/help/) menu page.
+
+## How not to use
+
+Do not route the app help button to a particular article page. Users may need help with something other than the screen they are on in the app.
+
+Showing users a menu page gives them various options that may be relevant to their problem.
+
+## Research
+
+“App help” was well understood as a label. People were consistently able to find and use the button.
+
+There were some issues with user experience when users were using the browser overlay. Some people:
+
+- navigated to other parts of the NHS website from within the browser overlay and lost their bearings
+- thought they were still inside the app while using the browser overlay
+
+We have made content changes to make it clearer when users are viewing help information and not acting inside the NHS App. This includes adding an "NHS App help" sub-heading on help article pages.
+
+We are [exploring how NHS website and third-party websites open from the app](https://github.com/nhsuk/nhsapp-frontend/issues/450).
+
+## Accessibility
+
+The button has been tested with visually impaired users. We found it to be accessible for screen readers.
