The page itself isn't yet optimized for mobile. That's coming soon. If you view the video in full screen mode, it's a lot clearer. There'll be an option to select the color scheme in a future release.
For me there won't be a "future" release because the landing page itself (the looks of the app) turned me off. The color scheme is garish, at best.
I'm not trying to be rude just give very honest feedback.
