This refers to software applications designed to function correctly on devices running Apple’s iOS version 9.3.5. For example, a user with an older iPhone 4S updated to its final supported operating system, iOS 9.3.5, would require applications specifically built or updated to operate within the constraints and functionalities of that particular iOS version.
The availability of suitable software is crucial for extending the usability of older devices. It allows continued access to essential services and functionalities, such as communication, entertainment, and productivity tools. Historically, as Apple introduces newer iOS versions, application developers often prioritize compatibility with the latest systems. This leaves users with older devices facing a shrinking pool of supported software, potentially rendering their devices obsolete sooner than desired.
