Apps in Fulcrum support having a custom image or icon to use to give them an identity or brand, whether viewed on the web or a mobile device. It makes it easier for users on mobile devices when there is an app image for each app.
To add an icon for your app:
Go to the app designer of the app you want to add an image.
On the right side of the app designer will be an App Image option.
Clicking on the plus icon will ask to upload an image.
NOTE: It's best to upload a JPEG or PNG that's at least 512x512. Images will be cropped to a square.
After the icon is added you will see the app icon on the homepage and the app pickers on the mobile apps.
