A feature integrated within the iOS operating system, it restricts a device to a single app, allowing control over which features are available. For instance, a parent might enable this feature on a device used by a child, disabling access to certain areas of an educational application to focus on a specific learning module.
The utility of this functionality lies in its ability to enhance focus, improve accessibility, and provide controlled environments. It offers a level of security and tailored user experience, preventing unwanted access to other applications or settings. Originally developed to assist individuals with cognitive disabilities, it has found broader applications across various user demographics.
