Numenera app add-ons are available for PC and Mac users of the Numenera Character Creator app. You can now purchase Numenera Character Options, Cypher Collection and the Technology Compendium: Sir Arthour’s Guide to the Numenera. When you purchase an add-on we will email you a code to redeem it in your PC or Mac version of the app. These codes will only work for the PC and Mac versions. Please note that the codes redeem in-app content based off the books. They are not the full PDF books.
