Yeah, definitely. Learning languages seems to be the largest use-case for spaced repetition apps, so building in lots of good content for language learning seemed like a smart way to differentiate and target ourselves at first. One of the biggest annoyances I had using the others was how much time I spent building my own decks - when, really, I just wanted to learn common, useful words. It's true that some apps include user-created content you can share, but the quality was pretty hit or miss - and usually didn't come with pre-associated images, sound, and example sentences.
