The language of our adidas Runtastic apps is the same as the system language of your android phone. If your system language is e.g. German, the adidas Runtastic apps will also be shown in german language.
How to change the language of your Android Phone:
Go to the settings of your android and choose "System". Scroll down until you reach "Language & Region". In the settings of "Language & Input" tap "Language & Region" and choose your language from the list showing up. To save your language press the back button. Your phone is now being updated to your chosen language. Therefore the adidas Runtastic apps update their languages too.
