Mobile devices have become one of the primary ways people access information and public services.
According to research from Fable, 81% of respondents believe accessibility barriers significantly affect their ability to use and enjoy their mobile devices. As reliance on mobile experiences grows, accessibility is becoming a major focus under ADA Title II.
What Is Mobile Accessibility?
Mobile accessibility refers to designing and developing mobile apps, websites, and digital content so that people with visual, hearing, motor, cognitive, or speech disabilities, as well as anyone using assistive technologies, can use them effectively.
Modern smartphones include built-in accessibility features such as screen readers, voice control, captions, text resizing, color adjustments, and alternative input options. These tools help users customize how they view content, hear information, and interact with their devices.
Why Is Mobile Accessibility in Focus Under ADA Title II?
Many users now rely on mobile devices as their primary access point to digital services.
Even public entities are increasingly delivering information and services through mobile applications and platforms, including:
- Transit applications
- Utility service apps
- Campus applications
- Healthcare portals
As a result, organizations need to ensure these mobile experiences are accessible to people with disabilities and anyone using screen reader software or other assistive technologies.
7 Common Mobile Accessibility Barriers That Are Often Overlooked
Despite being one of the most widely used media for accessing information online, there are several barriers to mobile accessibility that are often overlooked.
1. Gesture-Only Interactions
Some apps rely entirely on gestures such as swiping or drag-and-drop actions. These interactions may create difficulties for users who cannot perform those gestures.
Examples include:
- Swipe-only navigation
- Drag-and-drop actions
How to Reduce the Risk:
Provide alternative controls and ensure all functionality is accessible through multiple interaction methods.
2. Missing Screen Reader Labels
Buttons and icons without descriptive labels can prevent screen reader users from understanding what the controls do.
Examples include:
- Unlabeled buttons
- Ambiguous icons and controls
How to Reduce the Risk:
Use meaningful labels and verify compatibility with native accessibility APIs.
3. Small Touch Targets
Buttons, links, and other interactive elements that are too small or placed too close together can be difficult for users to tap accurately. This can create challenges for people with motor impairments, users with limited dexterity, or anyone using their device with one hand.
Examples include:
- Tiny buttons
- Closely spaced links
- Small checkboxes and form controls
How to Reduce the Risk:
Make buttons and interactive elements large enough to tap comfortably and provide adequate spacing between them to prevent accidental selections.
4. Orientation Restrictions
Some mobile apps only work properly in either portrait mode or landscape mode. Restricting orientation can make it difficult for people who use wheelchair-mounted devices, rely on assistive technologies, or prefer a specific viewing position.
Examples include:
- Apps that only support portrait mode
- Features that stop working when the device is rotated
- Content that becomes unreadable in landscape view
How to Reduce the Risk:
Support both portrait and landscape orientations whenever possible and ensure content remains usable regardless of how the device is held.
5. Inaccessible Authentication Processes
Some mobile apps make it difficult for users to sign in or verify their identity. Authentication methods that rely on a single interaction or technology can create barriers for people with disabilities and users relying on assistive technologies.
Examples include:
- One-time password (OTP) challenges that expire too quickly
- CAPTCHA tests that are difficult to complete
- Apps that only allow biometric login
- Verification steps that are not compatible with screen reader software
How to Reduce the Risk:
Offer multiple ways to sign in and ensure authentication processes work properly with assistive technologies and accessibility features.
6. Dynamic Content That Is Not Announced
Mobile apps often display messages, alerts, or updates without notifying screen reader users. As a result, important information may be missed, making it difficult to complete tasks successfully.
Examples include:
- Error messages that appear without being announced
- Success notifications after submitting a form
- Pop-up windows and status updates
- Changes to content that are not communicated to assistive technologies
How to Reduce the Risk:
Ensure that notifications, alerts, and content updates are properly announced so users are aware of important changes while using the app.
7. Mobile Forms That Are Difficult to Complete
Forms that are confusing or difficult to navigate can prevent users from completing important tasks.
Examples include:
- Missing labels on form fields
- Error messages that do not explain how to fix a problem
- Small input fields and buttons
- Forms that cannot be completed using only a keyboard
How to Reduce the Risk:
Use clear labels, descriptive error messages, logical form layouts, and accessible controls to make forms easier for everyone to complete.
8. Inaccessible Documents on Mobile Devices
Many people access documents on mobile devices, including reports, public notices, meeting agendas, downloadable forms, policy documents, and educational resources.
However, when these files are not designed for accessibility, users may struggle to read, navigate, or interact with them on mobile devices.
Examples of common problems include:
- Missing tags
- Incorrect reading order
- Poor text scaling
- Incompatibility with screen reader software
How to Reduce the Risk:
Create accessible documents from the start and ensure PDFs are properly tagged and optimized for mobile use. Organizations should also review high-traffic and frequently downloaded documents regularly to identify and remediate accessibility issues.
Other Hidden Digital Accessibility Risks Beyond Websites
An accessible website alone does not guarantee accessibility. Many organizations rely on additional digital tools and services that users interact with every day.
If these systems are inaccessible, they can still create barriers for people with disabilities and anyone using assistive technologies. Here are some common digital tools and services that should also be accessible:
- Online Payment Platforms: Inaccessible checkout flows and forms can prevent users from completing transactions.
- Mapping & Location Services: Interactive maps should provide accessible alternatives and clear directions for all users.
- Third-Party Service Providers: Accessibility responsibilities still apply even when external vendors provide the service.
- Event Registration Systems: Registration forms and ticketing platforms should be easy to navigate and complete.
- Learning Management Systems (LMS): Inaccessible course content, assessments, and videos can create barriers for learners.
- Public Meeting Platforms: Virtual meetings and webinars should support captions, transcripts, and audio description.
Mobile Apps vs Mobile Website: Different Accessibility Challenges
Although both mobile apps and mobile websites are accessed through smartphones and tablets, they do not present the same accessibility challenges.
- Mobile websites rely on web technologies and responsive layouts, while mobile apps use platform-specific controls and interactions.
As a result, organizations need to evaluate each experience separately to ensure users can access information and complete tasks without barriers.
Here’s a table of the different barriers that mobile apps and websites may face:
| Accessibility Challenge | Mobile Websites | Mobile Apps |
|---|---|---|
| Navigation | Poor responsive design and inconsistent layouts | Gesture-only interactions and complex navigation patterns |
| Screen Reader Support | Missing headings, alt text, and form labels | Unlabeled buttons and controls that VoiceOver or TalkBack cannot interpret |
| User Interaction | Keyboard accessibility and focus order issues | Small touch targets and unsupported gestures |
| Authentication | Inaccessible forms and CAPTCHA barriers | Biometric-only logins and inaccessible verification processes |
| Dynamic Content | Pop-ups and alerts may not be announced properly | Notifications and status changes may not be communicated to screen readers |
| Multimedia | Missing captions, transcripts, and audio description | Inaccessible media players and controls |
| Documents | Inaccessible PDFs and downloadable files | Inaccessible documents opened within the app |
| Third-Party Services | Payment gateways and external widgets | Integrated maps, booking tools, and external SDKs |
| Device Support | Challenges across different browsers and screen sizes | Differences between iOS and Android accessibility features |
While some barriers overlap, mobile apps often introduce challenges related to gestures, touch interactions, and native device features. Mobile websites, on the other hand, commonly face issues involving responsive design, forms, multimedia, and downloadable documents.
Organizations should test both experiences independently because an accessible website does not guarantee an accessible mobile app, and vice versa.
