Mobile app accessibility: good practice for all your customers

An accessible app is an app everyone can use: someone with low vision, an older customer, someone reading in bright sunlight or one-handed on the bus. Accessibility isn’t just for big companies: most good practice depends on your choice of colours and content.

Why it matters

Millions of people in Europe live with a disability, and many more simply have eyesight that declines with age. An app that’s hard to read loses these customers silently. Conversely, what helps a person with a disability helps everyone: higher-contrast text reads better in the sun, a bigger button is easier to tap.

What the law says

Since 28 June 2025, the European Accessibility Act sets accessibility requirements for many digital services, including e-commerce, apps included. Service microenterprises (fewer than 10 employees and under €2 million in turnover) are exempt. Even if you are, good practice remains a commercial advantage. For your specific situation, ask a professional.

Good practice, one by one

Well-contrasted colours

Text must stand out clearly from its background. Avoid light grey on white, text over a busy photo, or two bright colours of the same intensity. A good reflex: if you squint and the text disappears, the contrast is too weak. In the back office, the colour theme is set area by area (header, backgrounds, menus) with a live preview.

Readable text

A simple font, a comfortable size, short paragraphs. Phones let users enlarge text in their settings: the app must cope with that, one more reason to favour short sentences and an airy layout.

Alternative text for images

Screen readers (VoiceOver on iPhone, TalkBack on Android) read what’s on screen aloud. For an image, they read its description. Describe your product photos and visuals in one useful sentence: “Bouquet of pink peonies and eucalyptus” rather than “IMG_2045”.

Clear buttons

A button should say what it does: “Book this slot”, not “OK”. It should be big enough to tap with a thumb, and shouldn’t rely on colour alone to be understood.

Captioned videos

Captions help deaf and hard-of-hearing people, and everyone watching a video without sound, which is most people on public transport.

Simple forms

Every field has a visible label, errors are explained clearly, and you only ask for the essentials. See how to create a form in the app.

The checklist

1. Check the text contrast on every background.
2. Enlarge the phone’s text and check the app stays readable.
3. Describe every important image.
4. Name every button after its action.
5. Caption your videos.
6. Try the app with VoiceOver or TalkBack for a few minutes.
