Dynamic Type

An iOS accessibility feature that allows users to adjust the system-wide text size to meet their reading needs, from very small to very large. Apps that support Dynamic Type automatically reflow and resize their text content when the user changes their preferred text size in system settings. Lack of Dynamic Type support is one of the most common mobile accessibility issues, preventing people with low vision from enlarging text to a readable size. Android provides a similar feature through its font size and display size settings.
