need a rss based news cms & app

hey guys
happy to be a envato customer!
anyone know about a solution that let me fetch news from multiple rss sources and put in a db, and view on a mobile app?
more like a news portal, self posting using rss
there’s one in the market right now, but the maker of the app isn’t responcive and dont want to fix bugs, that’s relative to url encoding…
thanks,
Tayeb
