The modification of the typeface displayed on Apple’s iOS operating system is a function not natively supported within the system settings. User interface legibility and aesthetic preferences often drive the desire to alter the default system appearance. As an example, an individual with visual impairments might seek a bolder or larger style for increased readability across applications and system menus.
Altering the visual presentation offers customized user experiences, although this has historically been accomplished through methods outside the standard iOS feature set. The benefit could be improved accessibility for some users or a more personalized feel to their device. Historically, modifications often required advanced technical knowledge or relied on exploiting vulnerabilities in the operating system, introducing potential instability.
