All my projects at a glance

Apps

My apps are available for iOS, Android, Windows, Windows Phone, BlackBerry, and Firefox OS in the related app stores.

Most of the apps use Open Data and can be re-used and modified (Open Source).

Websites

Not every idea ends in an app. Websites are equally complex.

For every occasion and demand the appropriate implementation ;-)

Preview

These projects are not ready yet, but reached a status in which they suffice for a first impression.

Suggestions for improvement, constructive criticism, praise: all is welcome!

Concepts

When time is running short for implementing an idea, it may remain a concept.

If anyone has time and motivation, feel free to take care of the implementation.
