The Usability and Accessibility domain assesses whether the app follows any recognized design standards such as WC3, WCAG, Apple HIG or Android App Quality Guidelines. In addition it considers as critical that there is documentation that there was user involvement in the design, development, and/or ongoing enhancements of the app. General app design principles are assessed as well as the ability for users to personalize or customize certain parts of the presentation layer and notifications.
The domain also considers accessibility, including supporting particular user needs or requirements for disability or impairments.
Support is considered key to this category of the Framework, and includes the type of support that is available and the appropriateness of response to different types of questions.
