### **Accessing App Builder**
1. From the Event Backend, expand **Mobile App** in the left navigation menu.
2. Click **App Builder**.
This opens the Mobile App Builder where you can customize the appearance, navigation, and content displayed in your app.
### **App Theme**
Expand the **App Theme** section to customize your app branding.
#### **Event Logo**
Upload your event logo.
- Recommended size: **200 × 200 px**
- Supported formats: **JPEG, PNG**
#### **Event Thumbnail**
Upload the banner that appears on the app home screen.
- Recommended size: **1600 × 900 px**
- Supported formats: **JPEG, PNG, GIF, MP4**
- Multiple files can be uploaded to create a carousel
#### **App Title**
Enter the title that will appear on the app home screen.
#### **Accent Color**
Select the **Accent Color** for your mobile app.
This color is used throughout the app to maintain consistent event branding.
**Note:** In the Legacy App Builder, there were two additional color options available:
- Primary Color
- Secondary Color
These options have been removed in the new App Builder to better support **Dark Mode** in the new mobile app.
Dark Mode was not available in the legacy mobile app. Since the new app now supports both Light and Dark themes, using multiple custom color layers could negatively impact UI consistency, readability, and overall appearance in Dark Mode.
To provide a more consistent user experience across themes, the new App Builder now uses a single Accent Color configuration.
### **Quick Links**
Quick Links are the menu items displayed on the home screen that provide attendees with quick access to app features and content.
#### **Adding a Quick Link**
1. Expand the **Quick Links** section.
2. Click **Add Link**.

Click the Edit icon to configure the Quick Link. Available options include:

Some Quick Links may also include additional settings that are specific to that menu item. For example, certain Quick Links allow you to select which content, categories, groups, or records should be displayed when attendees open that menu item.
These settings vary depending on the selected Quick Link.
Click **Save Changes** after making updates.
#### **Managing Quick Link Order and Hierarchy**
To learn how to reorder Quick Links or create nested menu items, refer to:
