Building accessible apps

Introduction

Accessible design enables inclusivity and usability for all users, including those with impairments or disabilities. Making your app accessible allows more people to use it.

In addition, accessible design leads to more efficient apps which enhance user experience for all users.

This guideline document details various practices that help you build accessible apps and ensure a better experience for all users of your apps.

The POUR principles of accessibility

There are four key principles of accessiblity that form the basis for the Web Content Accessibility Guidelines (WCAG): Perceivable, Operable, Understandable, and Robust.

• Perceivable - information and user interface elements must be presentable to all users in ways they can perceive.

• Operable - user interface components must be operable for all users.

• Understandable - the operation of user interfaces must be understandable for all users.

• Robust - the content in your app must be robust enough that assistive technologies can interpret it reliably.
