Please don’t! Or at least make it possible to change the app language instead of following the system if you do. Plenty of apps have faulty ‘translations’ that just make the app unusable. Especially because app text typically has no context, so you get these weird literal translations.
Enjoy finding a literal english translation that corresponds to something I may want to do in your app!
But if you don’t have the D-ticket, good luck figuring out how the local ticketing machine works haha
