How can you measure mobile app accessibility for users with low confidence?

1 Define your target audience

The first step to measure mobile app accessibility for users with low confidence is to define your target audience and understand their needs, preferences, and challenges. You can use user research methods, such as surveys, interviews, focus groups, or personas, to gather insights about your users' demographics, goals, motivations, pain points, and behaviors. You can also segment your users based on their confidence level, using criteria such as frequency of use, retention rate, feedback, or satisfaction score.

2 Choose your accessibility metrics

The next step is to choose your accessibility metrics, which are the indicators that measure how well your app meets the needs and expectations of your users with low confidence. A combination of quantitative and qualitative metrics should be used, such as usability metrics for measuring how easy and efficient your app is to use, engagement metrics for gauging user interest and involvement, satisfaction metrics for assessing user happiness and loyalty, and accessibility metrics for determining how accessible and inclusive your app is for users with different abilities and situations. Examples of these metrics include contrast ratio, font size, readability score, completion rate, error rate, time on task, session length, screen views, bounce rate, retention rate, ratings, reviews, referrals, or net promoter score.

3 Collect and analyze your data

The third step is to collect and analyze your data, utilizing the accessibility metrics you have chosen. You can employ various tools and methods to gather and interpret your data, including analytics tools like Google Analytics or Firebase, testing tools such as WAVE or Lighthouse, feedback tools like surveys or reviews, and data visualization tools such as charts or dashboards. These applications can track user behavior, evaluate accessibility and usability, manage user feedback, and display data in a clear and engaging way.

4 Implement and monitor your improvements

The final step is to implement and monitor your improvements, based on the data you have collected and analyzed. To enhance your app's accessibility and usability for users with low confidence, you should simplify the design and functionality, using clear navigation, layout, icons, and labels. Additionally, you should optimize the content and language, using simple words, sentences, and paragraphs with translations or explanations when needed. You should also adjust the appearance and interaction, using appropriate colors, fonts, sizes, and contrasts as well as providing options for zooming or resizing. Finally, you should support accessibility and inclusivity by using accessibility features such as voice control or captions and following guidelines like WCAG or ARIA. It is important to monitor your app's performance and user feedback regularly with the same metrics and tools used before to make changes or updates as needed.
