Techniker Krankenkasse is committed to making the TK-Coach app accessible to all users. This statement is based on a test conducted by an external service provider and a self-assessment. It applies to the TK-Coach app in the App Store and Play Store, version 1.9.0 (Android) & 1.9.1 (iOS) from December 2025.

Non-accessible content

The following app content is not yet accessible:

Registration & forms

  • On Android devices, selection lists on the Registration page cannot yet be optimally operated with an active screen reader. This may make registration difficult at present.
  • After filling in form fields, blind users cannot immediately tell whether their entries are correct or incorrect. The screen reader does not yet automatically output error messages.
  • On iOS devices, links in switch button labels cannot currently be accessed or activated, e.g., in Settings > User Consent and Registration > Notice before Start.

Multimedia

  • The media player does not yet have controls for activating or deactivating audio description. This means that blind users are currently unable to fully access visual content.
  • Videos lack controls for subtitles. Hearing-impaired users therefore currently have limited access to content.
  • Recorded videos do not yet offer audio description or transcripts. As such, blind, visually impaired and cognitively impaired people can only partially access the content.
  • Podcasts are currently available without a text alternative. This means that deaf users are currently unable to fully understand the content.

Content & structure

  • Some images, graphical controls and information-oriented graphics do not yet contain complete alternative texts.
  • In structured content, some heading elements are missing; the reading order of the screen reader sometimes does not correspond to the visual structure or the focus jumps unexpectedly after actions.
  • Some texts, labels, error messages and control elements do not yet meet the optimal contrast ratio.
  • Some components do not yet provide all the necessary semantic information (name, role, properties).

Usability & customisation

  • Some content and functions are currently only available to a limited extent via keyboard. The focus for interactive elements is not always optimally visible.
  • Landscape mode and dark mode are currently only supported to a limited extent. This makes them difficult to use on certain devices and for users who are sensitive to glare.
  • Display errors may occur with very large text sizes (200% and above).

Accessibility will be improved gradually with regular releases.
