Mobile Marketing

Mobile Advertising is an efficient means to promote your product.

We can support your mobile marketing campaign both with ideas and with ad space. We integrate advertising into our apps in an unobstructive way so that it is still fun to use the apps. While the users definitely notice the ads, they don´t feel impeded in their interaction with the app.

Here is a good example.

If you would like to try iPhone apps as a new media for your mobile marketing, don´t hesitate to contact us at
