An app store is a distribution system through which users can find and install applications for supported devices and accounts. Listings, availability and purchase conditions can depend on platform, model, region and publisher choices. A store account or app purchase is separate from the credentials and permissions of a streaming subscription used inside the installed application.
A practical example
A television store may offer one player while a phone store offers a different edition from the same publisher. The viewer should use the listing appropriate to the actual device rather than assuming every familiar app name has one universal installer.
A common misunderstanding
A familiar name or icon is not enough to establish publisher identity. Follow the verified developer's distribution route and compare the listing details before entering account information into an application.
