A few of our apps are also available for iPad. Technically, the iPhone and iPad app are independent from each other. The navigation is not included as a feature on the iPad, as ist implementation is rather difficult and has not been required so far by our users. Due to its handiness, the iPhone is used more frequently than the iPad.
As the iPad mini is enjoying an increasing popularity, we’ve obtained several requests on this behalf. Therefore, our devolpment team is working on the navigation for the iPad.
