The language of our Runtastic Apps is the same as the system language of your iPhone. If your system language is e.g. German, the Runtastic Apps will also be displayed in German.
How to change the language of your iPhone:
Go to the settings of your iPhone and choose "General". Scroll down until you reach "Language & Region". In the settings of "Language & Region" tap "iPhone-language" and choose your language from the list showing up. To save your language press "done". Your iPhone is now being updated to your chosen language. Therefore the Runtastic Apps update their languages too.
