Why Mobile Accessibility Matters

A commuter with low vision uses VoiceOver to check bus arrivals. After we rewrote ambiguous labels, she messaged that one small change restored her independence during winter mornings. Share your own moment when accessibility removed a barrier and changed someone’s day.

Why Mobile Accessibility Matters

WCAG 2.2 principles guide mobile patterns, while Section 508 and EN 301 549 influence compliance requirements. Apple’s Human Interface Guidelines and Material Design offer platform specifics that clarify semantics and interactions.

Designing for Screen Readers

Use short, specific labels that describe purpose, not appearance—like “Send message,” not “Paper airplane.” Provide helpful hints that explain outcomes, especially for destructive actions. Invite your QA team to review labels aloud and share problematic examples we can collectively improve.

Designing for Screen Readers

Ensure titles, headings, lists, and groups are exposed with proper traits so screen readers present a meaningful structure. Reading order should match visual flow, avoiding disorienting jumps. Run a complete VoiceOver or TalkBack walkthrough and post your toughest navigation challenges for guidance.

Color, Contrast, and Visual Alternatives

Aim for at least 4.5:1 contrast for body text and 3:1 for large text, accounting for device brightness and outdoor glare. Test primary states and disabled elements, not just ideal samples. Share screenshots of difficult color pairs, and we’ll brainstorm resilient alternatives.

Touch Targets, Focus, and Motion

Use minimum target sizes of around 44 by 44 points on iOS and 48 by 48 dp on Android. Add sufficient spacing to prevent accidental taps. Post screenshots of crowded toolbars or lists, and let’s explore spacing strategies that preserve layout harmony.

Touch Targets, Focus, and Motion

Define a logical focus order that mirrors reading flow, including modals and toasts. Support hardware keyboards, D-pads, and switch devices with visible focus indicators. Share a video of a confusing focus loop you found, and we’ll troubleshoot strategies to fix it.

Honor user-selected text sizes, from small to extra-large, and verify that labels, buttons, and inputs reflow correctly. Avoid hard-coded truncation. Post before-and-after screenshots demonstrating how Dynamic Type or system scaling improved readability in your app’s most complex screens.

Use responsive constraints, wrapping, and intrinsic sizing so content adapts without overlap. Stack elements intelligently and support vertical scrolling when necessary. Share a stubborn layout where cards or buttons collide at large sizes, and we’ll propose resilient strategies to fix it.

Short sentences, consistent terminology, and descriptive headings help everyone, especially users with cognitive disabilities or limited proficiency. Replace jargon with plain language and provide summaries for complex steps. Comment with a confusing microcopy example, and we’ll suggest a clearer, friendlier alternative.

Multimedia: Captions, Transcripts, and Alternatives

Provide accurate, synchronized captions including non-speech sounds and speaker identification. Avoid auto-captions without review. Let viewers control caption size and background. Post your caption style guidelines or ask for feedback on readability across small screens and challenging backgrounds.

Multimedia: Captions, Transcripts, and Alternatives

Offer transcripts for podcasts and add audio descriptions where visuals carry key information. This benefits search, translation, and skim reading. Share an example scene that is hard to describe, and we’ll crowdsource concise, informative narration that respects timing and context.

Testing with Real People and Useful Tools

Run complete flows with VoiceOver and TalkBack, try external keyboards, and test one-handed use in bright light. Manual exploration uncovers context issues automation misses. Post a short test script you use, and we’ll suggest additions for broader coverage.

Testing with Real People and Useful Tools

Integrate platform accessibility scanners and linters into CI to flag missing labels, insufficient contrast, and small targets. Treat findings as actionable, not optional. Share your build pipeline and we will recommend tools or thresholds that fit your team’s workflow.

Testing with Real People and Useful Tools

Recruit participants with diverse disabilities, compensate fairly, and test real tasks on real devices. Close the loop by shipping fixes quickly and reporting back. Join our newsletter to receive research prompts, and volunteer your app for a community accessibility teardown.
