The process of installing applications on iOS devices through means other than the official App Store is known as a specific application installation method. For example, individuals or organizations might choose this approach to deploy internally developed software or to test beta versions of apps without utilizing TestFlight.
This alternative installation pathway offers benefits, including expanded software access and control. Historically, it provided a means to circumvent App Store restrictions. It allows for broader testing and distribution scenarios, providing greater flexibility for developers and specialized use cases, such as enterprise applications or specific testing phases.
