  • Mobile operability: Usability and full display of content in portrait and landscape format; pointing actions and operability by device movement possible with conventional input methods.
  • Keyboard operability: Interactive elements can only be operated with a keyboard and are highlighted when focused on.
  • Voice control: Controls have an accessible label that corresponds exactly to the visual description/name.
  • Compatibility with user agents: User agents and assistive technologies are informed about changes in the state of the user interface as well as status messages.
  • Assistance with interactions: Interaction with forms; pointer entries can be cancelled or undone.
  • Consistency/predictability: Consistent navigation; context remains when focused in or during input.
  • Semantic structure: Content is labelled with structural elements such as headings, lists and labels that reflect the context of meaning.
  • Comprehensibility: Headings, form labels and link texts are understandable, correct language declaration is used.
  • Display flexibility: The presentation of the content can be adapted to the needs of the users: text size, control over animated elements and media.
  • Contrast and sensory characteristics: Adequate contrasts, no expressions such as ‘in the picture on the right’ or ‘click the red button’; information is not conveyed solely by colour.
  • Non-text content (graphics): Informative graphic elements have useful alternative texts.
  • Multimedia alternatives Multimedia content is compatible with at least one alternative sensory channel.

Key findings

The Android version of SBB Mobile, like the iOS version, makes a good impression. The heading structure is correctly implemented. Timetable checking and the purchase of tickets work with the screen reader and the settings are accessible for the most part too. However, many switches are not correctly marked as such. Active tabs are not declared active by the screen reader, despite the corresponding status being visually recognisable. The app is insufficiently usable with a keyboard. With few exceptions, the content can be enlarged sufficiently and the contrast ratios meet the requirements in most cases too.
