There appears to be a missing closing </style> towards the end of the page which means the scripts after aren't being loaded.
I noticed via a site retheme on OK Cupid. A few minutes ago the "Get Crazy" button had a box to put in your phone number in order to get the App download link via text message.
You can probably still access it via the web interface on OK Cupid, unless I'm part of a testing group instead of a launch.
Linked me to the play store when I was browsing on my phone.
