You could always download a large PDF of the entire world of Skyrim and either print that out or clumsily navigate it on your phone, or you could wait for Dragon Shout, an upcoming interactive map for iOS. "The first version of the app contains an interactive map where you can drop annotated markers / journal entries down," the developer told Touch Arcade. "For example, yesterday I played Skyrim and left a bunch of dragon scales and bones on the side of a mountain because they were too heavy."
Even better, future updates plan to incorporate a social aspect, allowing "marker sharing, party or app-wide chats, pictures, and more." Want to tell your friend to "STAY AWAY" from that one cave you got whomped in? Or maybe, for the devious amongst you, encourage them to "CHECK OUT" said cave?
The app has been submitted to Apple and "should be out within the next couple of days" for both iPhone and iPad. With a $0 asking price, you can't really go wrong, can you?
