Automated testing

Jenkins Continuous Integration

Your iOS, Android and Desktop App is built and tested automatically and centralized by Jenkins. At every change.

DeviceWall Testing

Our DeviceWall with over 30 devices performs 24×7 automatic tests. We keep different generations and operating system variants of iOS and Android devices available to systematically test your app.

Over and over again.



Our team of experienced business analysts, technical consultants and certified software architects accompanies every project from the very beginning – flexibly, creatively and goal-oriented.


We discuss with you the functional direction, target group and create a concept for the perfect implementation.

Prototyping and UX Design

In addition to the early verification of the processes with a click dummy, we coordinate the UX design with you – for an optimal user experience.

Development and testing

Right from the start, we rely on automatic unit and integration tests on our device wall. This enables us to ensure the highest quality and reliability during implementation.

Backend and rollout

Each app comes with a container-based backend. This forms the basis for a secure and scalable operation for your app.
