Who we are

Dennis Block M. Sc.


Gregor Block M. Sc.


We design and develop beautiful user-oriented apps for the Android platform. Clean code is our passion, our robust codebase is easy to extend, maintain and test for future development cycles.

Our journey to become IT-professionals started at the vocational school to become an information technology assistant. Afterwards we graduated with a Bachelor's and Master's degree in Applied Computer Science. We did a lot of different projects together, most of them were Android related. While studying fulltime we worked as Android developers on the side and gained even more experience.

We love open source and have decided to contribute back to the community. Check out the Community section below.

We attempt to use the latest cutting edge libraries and tools. As a summary:

  • Kotlin / Java
  • Jetpack
  • Dagger
  • RxJava / Coroutines
  • MVVM / MVP / MVI
  • Material Design

What we do


We work with the latest tech-stack to create modern android application architecture that is loosely coupled, scalable, maintainable and testable.


Our maintenance service improves continuously your applications quality after the release to give your users the best possible experience.


We support you in optimising the strategy for your project by identifying and analysing weak points and developing solutions.


One of our strengths is the user-oriented design of mobile apps. Our focus is on usability to deliver the best possible user experience.
