App accessibility is the new must in mobile development

April 18, 2025

As the mobile app industry grows, ensuring accessibility is no longer optional—it’s essential. Accessible apps not only demonstrate social responsibility but also reach a broader audience, increasing downloads and profitability. But what does app accessibility mean, and why does it matter?  

What is mobile accessibility?  

According to the Web Accessibility Initiative (WAI), mobile accessibility involves designing apps that are usable by individuals with disabilities. It extends beyond smartphones to include smart TVs, wearables, car dashboards, and more. Accessibility ensures everyone, regardless of their abilities, can interact with your app.  

For instance, captions alone increased video engagement by over 500% in recent years, proving that small changes can yield significant benefits. Additionally, as populations age, the demand for accessible apps will rise, creating a growing market for inclusive technology.  

Why accessibility matters  

Approximately 57 million people in the U.S. alone have disabilities. This includes 20 million with dexterity issues, 8 million with vision impairments, and over 7.5 million with hearing difficulties. Accessibility makes it possible for these individuals to interact with apps effectively.  

While no current laws mandate app accessibility, the Americans with Disabilities Act (ADA) prohibits discrimination in public spaces. Forward-thinking developers can treat apps as public accommodations, showing inclusivity while future-proofing their designs.

Steps to achieve app accessibility  

To make your app accessible, you can follow guidelines like the Web Content Accessibility Guidelines (WCAG). Here are some practical steps:  

1. Provide captions and synchronisation 

Ensure captions for audio and video are properly synced. This helps users follow along without feeling rushed.  

2. Enable text-to-speech compatibility 

Incorporate support for screen readers and text-to-speech technology. This is vital for visually impaired users who rely on auditory feedback to navigate apps.  

3. Optimise for both portrait and landscape views

Maintain consistent information regardless of screen orientation. Users should not lose content when switching between portrait and landscape modes.  

4. Design for colorblind users

Use high-contrast colours and avoid combinations that are difficult for colourblind users to distinguish. Clear separation between text and background is crucial.  

5. Avoid flashing lights 

Flashing elements can trigger seizures in some users. If necessary, provide settings to disable such features.  

6. Allow adjustable timing

Avoid timeouts that disrupt users with cognitive or visual processing challenges. Features like dictation and adjustable reading times can help.  

7. Ensure easy navigation

Buttons and links should be clearly identifiable, using bold text, underlines, or visual separation beyond colour.  

8. Include adjustable settings  

Offer in-app controls for text size, brightness, and colour to accommodate individual preferences.  

9. Prepare for future technologies

Design your app to integrate with current and emerging assistive technologies, ensuring long-term compatibility.  

The bigger picture  

Making apps accessible benefits everyone—not just users with disabilities. It enhances usability, expands your audience, and future-proofs your app in an increasingly inclusive market.  

By adopting these best practices, you’ll create an app that meets user needs today while setting the stage for success tomorrow.
