Core Principles of Inclusiva Mobile Design

Te ramy WCAG is built on four core principles, often considerabered by thee acronim POUR: Perceivable, Operable, Understandable, and Robuss. These principles applicable directly to mobile app development.

Perceivable

Information and user interface contents mutt be presentable to users in ways they can perceive. Thii means provising text contectives for non-text content (np., images, icondes, icondes, videos), ensuring that content can bee presented in different ways (np., using screen readers to read aloud), and making it easyr for users tte see and heur content by ofering concert, resizeblage text, and captions.

Operable

User interface contains and via screaun reageron must be operable. This requires that all functiality be acceptable from a keyboard (including ding via screain reagement gestures), that users have enough time te te use content, that the app does does not cause contacures from flashing content, and that navigation is easy to use with consistent structure. For mobile, this means supporting touch, voye, and switcch input with out requiring fine motor control.

Zrozumiałe

Information and thee operation of thee user interface must be understanble. Thi involves using clear and previdtable language, provisiing instructions andd labels, offering consistent nawigation parafarts, and helping users avoid and correct errors. For example, error messages should d explain whatt wrong and how to fix, not just report a faullure code.

Robust Przewodniczący

Content mutt be robutt enough te interpreted reliable by a wide variety of user agents, including assistiva technologies. This means using semantic HTML or platform- nativie contexents that expose accessibility confidenties, and testing witch real assistive devices. As technologies evalue, robutt developn ensures your app beats accessible across future versions of operating systems and tools.

  • Support multiple input methods. In addition to touch, users may rely on keyboard (with or without on-screen keyboards), mouse, switch devices, eye tracking, or voice control. Use platform APIs (e.g., UIAccessibility on iOS, AccessibilityNodeInfo on Android) to expose custom actions. For example, a swipe-to-delete gesture should also be available via a long-press menu or adedicated delete button.

Manual Testing Checklist

  • Test with screen readers: VoiceOver (iOS) and TalkBack (Android). Navigate every screen with no vision (eyes closed).
  • Tess wigh keyboard- only navigation (iOS: Voice Control; Android: Switchh Acces). Ensure all elements are reachable.
  • Increase text size to max and verify no content is truncated or coverlapping.
  • Enable high contraST and invert colors modes; check readablity.
  • Ogranicz motywację i ensure animations stop or are replaced with static transitions.
  • Tett wigh color simulators (np., built- in iOS Simulator, Android Color Corrittion).
  • Test wigh a user who relies on assistivy technology (if possible) to uncover real-eternal issues.

Common Accessibility Faciliaures to Avoid

  • Images without out entertaintivy text (decorative images should have entil 1; Image1; FLT: 26 entitle3; Image3; Or entive1; Image1; FLT: 27 entitle3; Image3;).
  • Form fields without out behind 1; EDH1; FLT: 28 behind 3; EDH3; or placeholder text that disappears.
  • Custom gestures that have no incorporativa (np., swipe te unfriend with no button fallback).
  • Lows contrast text (gray on light gray) - always check ratio.
  • Interactive elements that are nott focusable (np., Xi1; Xi1; FLT: 29 Xi3; Xi3; witch tap gesture note exposed as accessible).
  • Modals or pouble that trap focus incorrectly or don 't notice their ir appearance.
