In myTuur you can change the app language. This choice affects not only menus and the interface, but also available texts and audio if content exists in your language.
If certain content is not yet available in your language, myTuur can fall back to another available language.
If you accidentally switched the app to Arabic, Chinese, Korean or Japanese and can no longer find the language setting, open Settings and tap the third menu item from the bottom. That is where the language switch is currently located.
