# Mobile support

When you develop a mobile-first solution, consider the following mobile app best practices.

***

## Create responsive designs

* The app UI should adjust automatically to fit a smaller mobile screen to ensure a consistent experience on any device.
* Prioritize vertical scroll over horizontal scroll, and avoid using any horizontal scrolling elements if possible.

***

## Ensure core features are available

* The core functionality of the app or theme should be available using a mobile device.
* Apps should notify users when features are not available on mobile.

***

## Provide seamless setup

* Apps that require theme setup should use [theme app extension](https://shopify.dev/docs/apps/build/online-store/theme-app-extensions) [app blocks](https://shopify.dev/docs/apps/build/online-store/theme-app-extensions/configuration#app-blocks-for-themes) and [app embed blocks](https://shopify.dev/docs/apps/build/online-store/theme-app-extensions/configuration#app-embed-blocks) so that the user doesn’t need to manually make changes to their theme’s code.
* Configuration and onboarding should be easy to follow and primarily take place inside the app.
* Minimize the number of external web properties users are redirected to post installation.
