I just tried it on my iPhone 5s. It didn't really work, layout wise. It loaded to a portion of the screen, and then I had to scroll over (to the right) to view the whole thing. Things are a bit jumbled, and I suck at explaining things so I have included a few screen shots.

I also clicked on the "Announcements" and it came up a bit different, but that might be because it's not live/active Blab?

It doesn't all fit on my screen, I have to scroll side to side to see it all.

Hope this is what you were looking for.
