The project was designed by the zurgams Kommunikationsagentur GmbH and the physiotherapist Martin Steiner and then implemented by us cross-platform for Android and iOS devices.

Auf die technische Expertise ist verlass. Auch auf den reibungslosen Projektablauf. Die Zusammenarbeit macht Spaß und das Ergebnis ebenso.

For Schwäbisch Media Digital Gmbh & Co. KG we redesigned the website of the bitzilla conference and subsequently implemented it for desktop computers and mobile devices.

By using a CMS, the customer can maintain all content independently. The website can be reached under conference.bitzilla.de.

What we do

With us you are completely carefree. We pick up on your idea, write a concept and then build a design, an app and backend, install the necessary server infrastructure and hand over your project just in time and completely finished.


From your idea to the finished app

Every project starts with an idea. We take your idea and develop a comprehensive technical concept for you.

1 Idea

After you have given us your idea in text form, we clarify the last questions by phone or at a personal meeting.

2 Concept

We then develop a comprehensive concept that includes a proposal for a screen design and highlights all technical aspects and general risks.



Graphical acceptance

You accompany the creation of the app in real time and can see the current state of development at any time using our project management tools.

3 Wireframe

Based on the technical concept, we develop a series of very concrete suggestions for a color and design concept.

4 Design

We are now implementing each concept developed in the concept with the design you confirmed before. In a flowchart, you can view the screen relations of your app at any time.



Software development

The implementation of the program code is the most expensive part during the creation of an app. We always work with contemporary technologies and concepts.

5 Clickdummy

The previously developed design is implemented as a click dummy and made available to you. You can now use your app and start the first tests.

6 Business logic

We develop the server backend and connect the clickdummy to the server. After this step, your app is basically functional.


Finishing touches

Testing and acceptance

After the implementation, we test the finished product together and take care of the fine tuning in close consultation.

7 Tests and acceptance

You test the developed app with colleagues, friends and family. Together we develop a release-capable and final version.

8 Release

Done. We toggle the switch, bring the servers to production and submit your app to the app stores around the world. Of course we are your partner for maintenance and advancement after the release!


For the implementation of your project, we always rely on the latest frameworks and technologies


We implement complex web applications based on the React framework developed by Facebook.


We develop classic websites using the robust and modern open-source-CMS bolt.

React native

One code, two apps. We basically develop for iOS and Android using the framework React Native.


For classic web applications we use PHP. A widely used programming language with a large community.


Symfony is one of the largest web frameworks and a good choice for stable server solutions.


We are also your partner in classic Android app development.


We implement resource-intensive parts of your infrastructure with high-performance server-side Javascript.


We model classical data structures with the relational database MySQL.


For larger data sets we use the document-oriented database MongoDB.


We have been gathering experience in native app development for iOS since this platform was created.

Amazon Webservices

We will host your products on the highly scalable cloud host Amazon Web Services.


Projects are published and updated fully automatically using build and release processes.
