The new app isn't simply a flashcard replacement tool for Anki, and there won't be a way to move flashcards in the new app into a different flashcard system. We are creating a full-on language immersion app that is based on flashcards, whereas Anki is simply a flashcard system.
The app has such an easy to use interface however, that you will be able to build cards at a much higher pace and you will have your deck populated in no time. The community will also be of great use here as we will all be sharing our materials and this will make populating decks so much easier and faster.
