The Pathfinder Roleplaying Game Compatibility License applies only to printed books, electronic books, and freely available websites, and is not available for use with apps.
Anything we've declared as Open Game Content in our products, though, is available under the OGL... but note that the OGL specifically restricts you from using "any ... trademark or registered trademark clearly identified as Product identity by the owner of the Product Identity", or from "indicat[ing] compatibility or co-adaptability with any Trademark or Registered Trademark in conjunction with a work containing Open Game Content except as expressly licensed in another, independent Agreement with the owner of such Trademark or Registered Trademark."
Which means you can't use trademarks like Pathfinder or Paizo in connection with your app (except for citing your sources of Open Game Content in your OGL Section 15 Copyright Notice). (Using the non-trademarked term "PFRPG" is legal.)
As far as acquiring a specific license from us, frankly, that option will only be considered for established software publishers with excellent reputations and solid business plans for their prospective apps.
