iPad and iPhone apps
The App Store is a digital distribution platform, developed and maintained by Apple Inc., for mobile apps on its iOS & iPadOS operating systems.
Apps can be downloaded on the iPhone smartphone, the iPod Touch handheld computer, or the iPad tablet computer, and some can be transferred to the Apple Watch smartwatch or 4th-generation or newer Apple TVs as extensions of iPhone apps.
Android is a mobile operating system based on a modified version of the Linux kernel and other open source software, designed primarily for touchscreen mobile devices such as smartphones and tablets. Android is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google.
