A service providing remotely accessible instances of the Apple operating system, typically used for testing and demonstration purposes, allows developers and other professionals to interact with iOS applications within a web browser. This capability is employed, for example, to showcase a new mobile game or to provide widespread access for user acceptance testing, eliminating the need for physical devices.
The remote access and cross-platform compatibility that this type of service delivers are significant advantages. It reduces the costs associated with procuring and maintaining a large inventory of physical iOS devices for testing. Historically, the constraints of physical device availability hindered widespread app testing, delaying development cycles and increasing expenses.
