To change the app icon, click the Browse button to launch the Media Library and upload a square image. Drag and drop it onto the Icon placeholder and close the Media Library. Enter a short name (12 characters or less) to label your app on the home screen of mobile devices.
Tip: Click the Help tab under any of the menu items, for more information on image sizes and options.
Tip: Due to the limitation of mobile devices, users who install your app before you make changes to the Home Screen Image and Name will have to re-install the app to see the update. So ensure you’re happy with the Home Screen Image and Name before sending the app to clients, customers, staff etc.
