"apps for the curation and creation of content"

That seems overly broad too and I suspect courts would distinguish between creation vs curation. The 53 app is about the former whereas FB's is the latter.

Also think about someone searching for an app to draw and paint. It's unlikely the FB's Paper would show up in the results. Even if it did, would most people confuse it for a drawing/painting app?
