Probably not as it was a way to promote Koyomimonogatari and here: http://www.monogatari-series.com/koyomimonogatari/
But it wont be of much use now that the year is over.
There is a Kizumonogatari app though, but afaik it's just a way to get info on the movie releases and watch trailers: https://play.google.com/store/apps/details?id=com.aniplex.kizumonogatari
