When you’re arranging icons on your iOS home screen, tap-and-drop one app icon to another will create a new folder. iOS by default will use the app category as a suggested name for the folder, and you can edit and change the folder name at will. But there is no way to leave the folder name as blank.
Well this trick will help you create a folder with no name. First you need the Starbucks app that you can download free from the App Store. Call it a bug or clever hack, you need the Starbucks app for this trick to work, and only that app. When you tap-and-drop the Starbucks app icon to another app, you will notice that the suggested folder name is empty. That’s it.
