Is it allowed to launch two Apps, which are the same Apps just in two Languages? F.x. ExampleApp in German and ExampleApp in English. This way there could be some features or Design changes in the German App which arent in the English app.
Two Apps of the same App?
Bad, BAD choice. You can include many localizations in a single app bundle - this way, the user has not to care about which version to download. Also, you are able to adjust the layout or enable/disable functionality by querying the current language your app is running in if you like.
