Where is the "+" of that app?

I cant see any advantage of that app except allowing several accounts, but who needs this? It is just the regular web version loading in an app frame. So far that would be ok and even nice, but it is slower than the web version. When I open an article mentioned in my stream and want to go back to my stream from the article the app loads the stream again every time what takes about 10 seconds. At least it was for free... Well and the graphic work is really ugly...sorry
