A World of Ice and Fire
A World of Ice and Fire, sometimes titled George R. R. Martin's A World of Ice and Fire — A Game of Thrones Guide, is a companion guide available as a mobile app for iOS and Android. The reference work, which contains information about the people, houses, places, and maps of the Known World, was written by Elio M. García, Jr. and Linda Antonsson of Westeros.org with input from George R. R. Martin.
The app is designed by Smashing Ideas and is published by Random House. It contains illustrations from Fantasy Flight Publishing. According to Apple's App Store, version 1.0 was released on November 25, 2012; version 1.3 from September 20, 2013, added six of the maps from The Lands of Ice and Fire. The app is considered semi-canon.
The free basic version of the app contains dozens of sample entries from the People and Places subject categories which cover both historical and current events from throughout the timeline of the books, as well as selected preview chapter excerpts from The Winds of Winter and The World of Ice & Fire, and an option to download portions of the "Westeros" and "Journeys" maps from The Lands of Ice and Fire.
Additional content including more detailed and exclusive guide items, the full interactive maps, and several hundred more informational entries, which extends the coverage subjects to Houses, Groups, Religions, Creatures, and Things, is unlocked via in-app purchases as "InfoPacks" corresponding to each novel, which can be paid for separately or as a bundle. The app can be set to hide or reveal spoilers for novels as-yet unread by the user.
