infoStatus: Fully developed, not deployed. We built the apps and admin dashboard completely. However, Tafel Deutschland decided against deployment. The technical work and our learnings remain valuable.

Project Overview

Tafel.app was a groundbreaking digital solution developed by WebPX on behalf of Motus UG. The platform was designed to demonstrate how technology and social work can harmonize perfectly. We developed a comprehensive solution consisting of two mobile apps and a web dashboard, specifically designed for use by Tafel Deutschland. The project exemplifies how thoughtful digitalization can increase efficiency and create more time for what matters most: connecting with people.

Commissioned by Motus UG, we developed a solution consisting of three closely integrated components: the Tafel.app for customers (digital registration and virtual queuing), the Tafel Scanner for staff (QR-code-based check-in system), and a web platform for administration. All components were developed with a focus on usability and accessibility, as the target group at Tafel Deutschland is very diverse - from young families to elderly people without smartphone experience.

Particularly challenging was developing a solution that works for both tech-savvy and less experienced users. Through intensive user research and iterative prototyping phases, a platform emerged that maps complex processes in an intuitive way. Strict GDPR compliance was not just a legal necessity but a core feature that builds trust among sensitive target groups.

The calculated potential of the solution we developed for Motus UG with nationwide deployment was impressive: Over 300,000 hours of volunteer work could have been saved annually, while simultaneously improving service quality for food bank customers. However, the project was not implemented – Tafel Deutschland decided against adopting the solution. Nevertheless, the technical work and experience gained remain valuable.

What We Learned

Even though Tafel.app was not implemented, we gained valuable insights:

  • • Complex Stakeholders: Decision-making in non-profit sectors often takes longer than expected
  • • Technical Excellence Isn’t Enough: A good solution also needs the right circumstances
  • • Flutter for Complex Apps: The technology proved itself – fast development, native performance
  • • Privacy by Design: GDPR-compliant architecture from the start saves time later
