The Apple App Store is a digital distribution platform where customers can buy and download digital software and applications. Apps (short for applications) are software tools that provide additional functionality to an operating system. Apps purchased from the App Store are stored in iCloud for easy access from any signed-in device. Apple maintains that it holds a trademark on the term "app store," but the term is used to reference any platform where apps are sold. Examples of other app stores are Google's Google Play, the Amazon Appstore, and Microsoft's Windows Store.
