With our iOS app you can change your interface language by clicking on "My Profile" and "Settings" before scrolling to "Interface Language". Once you have selected the appropriate language, close the app and reopen it for the changes to take effect.
In our Android app you can now update your interface language too! Go to the menu button > "Preferences" and click the edit icon beside "Interface Language" to switch it over. Your app will automatically refresh and you'll be able to continue your learning straight away!
