No iOS-App in Germany
sadl I cannot find your mobile app within iTunes. If I click on your link iTunes prompts me to swap for a different country. Having swapped I still cannot download your mobile app.
Our old iOS app is currently not available, but we will soon release our brand new native app with lots of features from the web-app and it will be available globally very soon.
