Flashcards that you create on the Brainscape website should automatically appear in the iPhone or Android app, assuming that you are signed in with the same account. If they do not appear automatically, then just select the ellipses at the top of the My Classes screen in the app and choose 'Sync Account'.
It is also possible to create a new class directly on the mobile app by clicking the + to create a new class, and then you will be prompted to create decks and flashcards.
