9 Free Mobile Accessibility Testing Tools

According to W3C “Mobile accessibility” refers to making websites and applications more accessible to people with disabilities when they are using mobile phones and other devices. WAI’s work in this area addresses accessibility issues of people using a broad range of devices to interact with the web: phones, tablets, TVs, and more.

Accessibility testing on mobile devices can be made easy with the following tools, while automation catches 40% of the bugs we always need to perform manual accessibility audits to make sure that applications are universally designed.

1. Accessibility Inspector in Xcode
   Apple provides the Accessibility Inspector testing tool that can be launched by choosing Xcode > Open Developer Tool > Accessibility Inspector in the menu bar or Dock. You can download Xcode from the Mac App Store for free. The Accessibility Inspector presents a utility window that displays the information properties (and values), action methods, and position in the accessibility hierarchy of the object currently under the mouse pointer.

5. Debugging Firefox for Android over USB
   It’s been possible for a long time to connect the Firefox Developer Tools to Firefox for Android so you can debug your mobile website. Until now, this
   was a fairly complex and error-prone process. From Firefox 36 we’ve made the process much simpler: in particular, you don’t need to deal directly with
   theadbtool at all. Now you connect using
   WebIDE, which takes care of setting up adb behind the scenes. For this to work, you need at least Firefox 36 on the desktop and Firefox 35 on the mobile device.
6. Remote Debugging on Android with Chrome
   Remote debug live content on an Android device from your Windows, Mac, or Linux computer.
   • Set up your Android device for remote debugging, and discover it from your development machine.
   • Inspect and debug live content on your Android device from your development machine.
   • Screencast content from your Android device into DevTools.
7. Accessibility Scanner
   Accessibility Scanner is a tool that suggests accessibility improvements for Android apps without requiring technical skills. Just open the app you want to scan, then tap the Accessibility Scanner button to find items in the app that might benefit from accessibility improvements. You can use this app to suggest changes to developers or to make changes yourself.

   Accessibility Scanner suggests improvements such as enlarging small touch targets, increasing contrast, and providing content descriptions so that your app can be more easily used by individuals with accessibility needs. Designing for accessibility can allow you to reach a larger audience and provide a more inclusive experience.
