KIND, a leading family business in the field of audiology and optics with over 700 specialist shops in twelve countries, places particular emphasis on high-quality products and personal consultation.


The KIND app is a digital solution that has been developed specifically to support customers digitally during the fitting of their (first) hearing aids. The aim: more successful fittings, higher customer satisfaction, and a long-term increase in hearing aid sales.

Safe start: Guided onboarding and comprehensible learning content

The KIND app makes it easier to enter the world of hearing aids with a clearly structured onboarding process and model-specific educational content. Users are guided step by step through the initial use, receiving individual tips and understandable explanations – for more security, less uncertainty, and a successful start.

  • Partial view of the KIND mobile app focusing on a hearing aid. At the top, it says "Congratulations on your new hearing aid". Below is a card with a graphic of a hearing aid, underneath which is the model name of the hearing aid. Below that is a button with the label "Get to know your hearing aid".
  • under which the text states: ""Congratulations on your new hearing aid", and additional welcome text. Below it is a red button with the inscription "continue".
  • Tile titled "Learn How to Use Your Hearing Aid", progress indicator (0 out of 6 learning contents completed), illustration of a hearing aid and button "Discover Now".
  • Smartphone screen with a tip for getting used to the hearing aid and an illustration of a bird, buttons "Back" and "Next".
  • Video preview featuring an image of a hand cleaning a hearing aid, titled 'How to Clean Your SlimTube' and a button 'Learn More'.

Digital support for a smooth hearing aid fitting

The app supports customers in the critical phase of hearing aid adaptation – where everyday life begins and questions arise. With features like the hearing diary and personalised reminders, the app ensures better alignment between the user and the specialist shop. The result: simpler, more personalised adjustments and higher satisfaction.

More service comfort: caregiver routines and appointment booking via app

The KIND app reliably reminds you of important care routines and allows for easy booking of service appointments – anytime and anywhere. This ensures the optimal functioning of hearing aids, while relieving audiologists and providing customers with consistently supported service.

Tile titled "Clean Your Hearing Aids", note on next cleaning "in 29 days" as well as button "Do it now" and link to the care routine.

Central interface of the omnichannel strategy

The KIND app is a central component of the omnichannel strategy, which seamlessly connects digital and physical touchpoints to create a consistent customer experience. As a digital interface, the app enhances personal advice in the specialist shop with smart services such as fitting guidance, care routines, and appointment booking – thereby strengthening customer loyalty and competitiveness in the digital age.

Graphic in the form of a horizontal infinity symbol with a gradient from dark blue to light blue. The loop is divided into the sections "Unaware", "Aware", "Consideration", "Evaluation", "Decision", "On-board", "Adoption", "Value Realization", "Loyalty", "Advocacy".

Accessible design for the best possible user experiences

With our user-centred UX/UI approach, we have designed the KIND app not only to be intuitive but also accessible – verified according to current WCAG standards.


From June 2025, the Disability Accessibility Strengthening Act (BFSG) will come into effect. Our Accessibility Check provides you with a sound analysis and clear recommendations – for digital products that are legally secure and accessible to all.
