This is the only other forum that matters to me and doesn't have it. In addition, the stand alone app is more useful than accessing the site through a browser. I couldn't even access the site directly on my Note 2 via Chrome. I had to Google, select one of the links below the main site (via the results), log in, and then go back to the forum. That was pretty unnecessary IMO.

For people who are members of a lot of forums, it makes more sense to have an app that aggregates everything.
