I'm glad there's finally an app like this for the US, but... – NicoPlayer - Niconico Video Player for free Review

This app really needs to have an English interface language option. I mean, if the app is available in the US, a country where most people don't speak Japanese fluently, you'd expect for the app to have an English interface instead of a Japanese one. And there aren't even any labels for everything in English, either! I'm overjoyed that an app that allows videos on Niconico to be viewed exists now, but with a Japanese interface, it can barely be used at all if you can't read Japanese!
