A Community Publication about All Things Mobile
Now powered by OX!

This project was initiated in 2009 with the aim to spread knowledge about mobile technologies and encourage people to enter our community or deepen their existing knowledge. With this edition, OX took over the project and will be driving it forward.

More than twenty writers from the mobile community share their know-how in dealing with topics such as accessibility in mobile apps, UX design, mobile analytics, prototyping, cross-platform development, native development, mobile web and app marketing.

As of today, more than 100,000 hardcopies have been distributed since 2009. Universities and schools in Germany, Netherlands, UK, Spain and South Africa use the book as teaching material. The electronic versions (ebook and pdf) have been downloaded hundreds of thousands of times and the content has been translated into several languages.

Don't Miss a Single Edition

For each new release, the whole content is completely reviewed and updated.

In older editions, for example, there are texts on the development of Bada apps, BlackBerry Java Apps, Augmented Reality and other topics, which are no longer contained in the current version for reasons of topicality or space.

Here, you can rummage through some older issues. On request, we can also send you hardcopies of previous versions.

We release a new version of the Mobile Developer's Guide once a year. If you would like to get in touch with us feel free to send us a message.
