Use the Mobile App Builder to assign your Next Experience themes.

## Before you begin

Role required: admin

To use Next Experience theming, you must have Next Experience enabled
on your instance. For activation instructions and more information on Next Experience, see [Exploring themes in Next
Experience](https://www.servicenow.com/docs/access?context=next-experience-theming&version=xanadu&pubname=xanadu-platform-user-interface&ft:locale=en-US).  
Note:  
If you are a new customer starting with the Xanadu release, Next Experience is active by default on your instance. No activation is required, and your mobile apps use the Polaris theme automatically.

## Procedure

1. Open the Mobile App Builder by navigating to AllSystemMobile App Builder.
2. Select the application that contains the mobile app you want to theme.  
   For example, Now Mobile.
3. In the menu on the left side of the screen, select Mobile app configs
4. Select the mobile app you want to theme from the list.
5. In the Mobile theme section, select a theme from the list.  
   With Next Experience enabled, your instance uses the
   Polaris by default. If you want to continue to
   use this theme, you do not need to update this field. You will only need to
   change this field if you have a custom theme you want to apply to the app,
   or if you had previously opted out of Next Experience.

   For information on creating your own themes, see [Exploring themes in
   Next Experience](https://www.servicenow.com/docs/access?context=next-experience-theming&version=xanadu&pubname=xanadu-platform-user-interface&ft:locale=en-US).
6. Click the Save button in the upper right corner of the screen to save your changes.  
   Your new theme is applied immediately, logged in users will see the new theme the next time the app refreshes.
