The phrase identifies resources outside of the official Apple-controlled environment where software applications intended for use on iPhones, iPads, and iPod Touch devices can be discovered and installed. It refers to platforms that offer a different selection of apps, or alternative distribution methods, compared to the standard channel. Examples include repositories offering emulators, customized utilities, or apps that do not meet the official store’s guidelines.
The availability of such resources allows users to explore a broader range of functionalities and customization options for their mobile devices. Historically, their emergence has been driven by a desire to circumvent restrictions imposed by the official store regarding app content, developer access, and revenue sharing. This can provide benefits to both users seeking specific functionality and developers seeking alternative routes for app distribution.
