Mobile Accessibility Testing: A Complete Guide
This article delves into the fundamental concepts of mobile accessibility and offers useful advice and resources for evaluating the accessibility of Android and iOS apps.
What is essential when it comes to creating a mobile app or site? Of course, the idea behind the product. However, it will also be a success when your targeted customers can use the app, or the user experience is good enough. Letting mobile applications be accessible to everybody, including users with disabilities, is very important. This not оnly fulfills recent legislation but also gives a competitive advantage.
In mobile application testing, accessibility to all users, including users with disabilities, should be guaranteed. Based on the World Health Organization report, more than one billion people globally—about 15% of the world population—live with some sort of disability, which is likеly to almost double by 2050, underlining the growth in demand for accessible designs in testing within mobile apps. This is going to ensure that apps are all-inclusive and usable by any person irrespective of his physical or cognitive abilities.
This article explores the bаsic principles of mobile accessibility and provides practical tips and tools for testing the accessibility of Android and iOS apps.
Why Mobile App Accessibility Testing Is Important
Mobile app accessibility testing ensures that applications are accessible and usable by everyone. Here are key reasons for its importance:
- Compliance Requirements: Many nations and governments have made accessibility testing mandatory for enterprises as part of compliance efforts. Complying with these requirements is essential to prevent legal consequences.
- Functional Excellence: A mobile app must pass numerous tests to function well and deliver an excellent user experience. Accessibility testing ensures the app is designed to accommodate users with diverse abilities.
- Inclusive Development: Accessibility testing for mobile apps should be considered during the development phase to ensure that the application or website is inclusive. Proactively addressing accessibility concerns contributes to a more universally usable product.
- Social Responsibility: Accessibility testing for mobile apps is becoming increasingly crucial in various circumstances, driven by inclusion and social responsibility principles. Prioritizing accessibility is about meeting legal requirements and doing the right thing for all users.

Common Mobile Accessibility Issues
Ensuring mobile app and website accessibility is crucial to providing an inclusive user experience. However, certain practices can hinder accessibility for users with disabilities. Here are some common issues to avoid during the design and implementation phases:
- Unspoken Form Validation Error Messages: Error messages should be accessible to screen readers, allowing blind users to understand and correct form submission errors.
- Unspoken Success and Announcement Messages: Success messages need proper accessibility announcement methods (e.g., WAI-ARIA) for screen readers to convey them effectively.
- Placeholders Used Without a <label>: Placeholder text inside form fields may affect cognitive accessibility and usability. Using <label> elements is recommended for better accessibility.
- Modal Dialogs Focus Issues: Modal dialogs should appropriately grab the screen reader's focus, and keyboard and screen reader focus should be restricted within the modal content.
- Missing Mobile Keyboard Usability Enhancements for Input Types: Mobile phones can display a different touchscreen keyboard depending on the data types the user is typing on their device.
Individual and community developers can help mitigate these challenges by bridging the gap with accessible designs. These designs help create more inclusive digital environments that reach users of all abilities. Our team has helped clients identify and resolve some of these common issues to ensure their apps satisfy the highest accessibility standards.

The Checklist to Follow During Mobile Accessibility Testing
Touch Targets and Placement
The improved resolution of mobile devices has allowed many interactive elements to be displayed on a small screen. However, these elements should be large enough and spaced far enough apart so that the user can reach them with a touch without having to stretch. When users need to use quick gestures on their mobile devices, the tap targets within an app should be large enough to interact confidently and accurately.
Developers need to consider the placement of interactive elements in mobile apps. The location of buttons and touch targets should be easily accessible regardless of how the device is held. This means considering factors such as whether the user is left- or right-handed and the range of motion of their thumb. (For a better understanding of user experience, read our article on mobile app usability testing to learn how to make your app user-friendly and intuitive).
To make mobile apps user-friendly, here are a few ideas for touch target placement:
- Place buttons in a convenient location.
- Ensure that all interactive components are flexible and easy to use.
Color Choice and Color Contrast
Check the foreground-to-background color contrast ratio to ensure it is at least 4.5:1 for standard text and 3:1 for large text and icons. You can use tools like Color Contrast Analyzer for iOS or Accessibility Inspector and Accessibility Scanner by Google for Android to verify the ratio. A low color contrast ratio can make the material difficult to read. Avoid combinations like red and green when selecting colors, as they may cause difficulties for those with color blindness. There should be no flashing lights or overly bright colors.
Different Designs for Different Screen Sizes
Mobile devices have smaller screens and unique aspect ratios, which makes it essential for designers to consider these factors when creating native apps. Due to the limited amount of information that can be viewed on a tiny screen, users may need to zoom in on content, especially those with eyesight problems. To address this issue, the following ideas can be implemented:
- Provide touch controls and preset screen sizes for content to reduce the need for low-vision users to zoom in and out.
- Place the form field behind the labels instead of next to them.
- Reduce the amount of data on each page by offering a mobile website specifically designed for mobile devices or intentionally constructing the website for mobile viewing.
- Change the link text length based on the device's viewport width.
Consistent Navigation and Layouts
Consistency in content, layout, and navigation is crucial for a good user experience. Users with weaker motor skills may need help using a mouse or keyboard and prefer mobile apps to web browsers. Mobile apps with assisted navigation can benefit all users by guiding them from one option to the next.
Simple Data Entry Methods
Mobile devices and native applications offer multi-modal data entry, which enables users to input data using different methods such as speech, a wireless keyboard, and an on-screen keyboard. Replacing text entries with these methods can save time and be easier for some users. To enhance the user experience and prevent errors, it is recommended to integrate select menus, radio buttons, and checkboxes or use auto-fill functionality for information like date, time, and location. Offering alternatives to typing, such as data exchange between apps and dictation, can also save time and improve the overall app experience.
How to Ensure Your Mobile Applications Are Accessible
First is assessing your mobile applications for mobile accessibility. Ensure your app supports the device's operating system features, such as larger text and screen readers. The most effective way to ensure accessibility is to test early and often in your development cycle. For existing products, accessibility testing is crucial to assess usability for everyone. Testing on mobile accessibility should always be conducted in an automated form with software and manually. These tests include:
- Screen reader testing: A screen reader is the software used by blind users. One powerful way that a developer or designer can test for any type of barrier or problem in a mobile site, which might prevent a user from accessing and navigating content, is to watch how the screen reader software will interact with a mobile site.
- Mobile accessibility checker or scanner: It evaluates a sample of your website pages—including mobile pages—for accessibility issues. This sample shows you what to fix on the selected pages and likely where you'll have problems on other pages.
- Color contrast tests: Color contrast testing tools are used to determine the legibility and contrast of visual elements in websites and mobile apps, such as text and graphical controls.
- Usability testing: It allows for assessing the overall user experience, ease of task completion, and determining what problems the users are experiencing that design can resolve.
