Who are the top providers of accessibility testing for mobile applications?

Ensuring mobile applications are accessible to all users, including those with disabilities, is crucial for inclusivity and legal compliance. Top providers in mobile application accessibility testing offer a blend of automated tools, expert manual audits, and user testing with assistive technologies.

Here are some of the leading providers and approaches in mobile app accessibility testing:

• Dedicated Accessibility Consultancies: These companies specialize exclusively in accessibility and often provide the most in-depth audits and remediation guidance. They typically employ certified accessibility professionals, including individuals with disabilities, who conduct thorough manual testing using screen readers (like VoiceOver for iOS and TalkBack for Android), keyboard navigation, and other assistive technologies. Level Access and Allyant (formerly Microassist) are examples of such firms, offering comprehensive services that include audits, legal compliance support (ADA, WCAG, Section 508), and specialized training.
• Specialized QA and Testing Companies: Many reputable QA and software testing firms have robust accessibility testing practices. They integrate accessibility checks into their broader mobile testing services, typically combining automated scans with meticulous manual review. Companies like QualityLogic and iBeta Quality Assurance are recognized for offering a wide range of mobile testing services, including accessibility.
• Platform-Based Accessibility Tools: Several platforms offer integrated accessibility testing capabilities within their broader testing suites or as dedicated solutions. These often feature automated scanners that can detect common WCAG violations and provide functionalities for manual inspection. LambdaTest, for instance, has an Accessibility Testing Suite that helps automate accessibility checks and integrates with existing development workflows.
• Open-Source and Built-in Tools: While not service providers, the following built-in and open-source tools are indispensable for many organizations conducting accessibility testing:
  • Google Accessibility Scanner: A free tool for Android that helps developers identify common accessibility issues in their apps.
  • Xcode Accessibility Inspector: Apple's native tool within Xcode for inspecting accessibility properties of iOS applications and simulating screen reader interactions.
  • VoiceOver (iOS) and TalkBack (Android): The native screen readers on their respective mobile operating systems are fundamental for conducting manual accessibility tests to understand the user experience for visually impaired individuals.

When selecting a provider, it's essential to consider their expertise in relevant accessibility standards (WCAG, ADA, Section 508), their combined use of automated and manual testing methodologies, their ability to offer actionable remediation advice, and whether they incorporate feedback from actual users with disabilities into their testing process.
