We played with explaining it on mobile but found that it led to confusion. It's an unfortunate stop gap for now until we have a mobile experience, but certainly agree that copy and mobile landing page isn't the best.
Why not at least have the video available? most people visting your site at this point are probably coming from more affluent backgrounds, thus even if they did get to your site on their phone they likely have a computer and would understand a video explaining whats going on.
