Accessibility

What we have done

• Every form field and button has a name that a screen reader can read, and headings follow a logical order.
• Buttons and chips are at least 44 pixels tall on phones, so they are easy to press.
• Text colours meet the 4.5 to 1 contrast ratio in both the light and the dark theme. This is checked by a test on every change.
• A "Skip to content" link is the first stop when you use the Tab key.
• Animation is switched off when your device asks for reduced motion, and the 3D picture on the home page stops turning.
• Error messages and results that change are marked up so that screen readers can announce them.
• The app works at phone width and in light and dark themes, and its tools work offline once they are saved on the device.
• At 320 pixels wide, which is a 1280 pixel screen zoomed to 400 percent, every tool wraps its content instead of cutting it off or needing sideways scrolling. A browser test checks this on every change.

How we check

• An automated accessibility scan (axe) runs on the main screens, in both themes, on every change.
• A Lighthouse accessibility score of at least 95 is required on the key pages before a change is accepted.
• The screens we have measured score between 98 and 100.

Automated tools find only part of the problems. They cannot tell whether a screen is easy to use.

What has not been checked yet

We have not yet done the following, so we cannot say the app works well for these cases:

• Testing with screen readers (VoiceOver on iPhone and Mac, TalkBack on Android).
• A person completing the main tasks with the keyboard alone.
• Making the text larger on its own, without zooming the page, and zooming on a real device.
• A review of places where colour alone carries meaning, such as status labels.
• A text description of the twelve clinical areas for screen-reader users on the home page picture.
