Accessibility in mobile apps is the practice of designing and developing an application so that people with different abilities can use it effectively. Mobile app accessibility can include support for screen readers, sufficient color contrast, scalable text, clear navigation, alternative text for images, captions, and controls that do not rely on a single type of interaction.
Accessibility helps make mobile applications usable by a wider audience, including people with visual, hearing, motor, or cognitive impairments. Following accessibility best practices can improve the overall user experience, make interfaces easier to understand and navigate, and help businesses meet accessibility requirements and platform guidelines.
A mobile app can improve accessibility by allowing users to increase text size without breaking the interface, providing descriptive labels for buttons that can be recognized by screen readers, and ensuring that important information is not communicated through color alone.
