The Dungeon Crawl Classic RPG is a fun fantasy RPG with a distinct take on fantasy. I had a lot of fun refereeing it during the playtest period. One downside of the system is the numerous charts that need to be referenced. It not a flaw, they are an esstential part of how the DCC RPG plays, but still when you have lots of charts referencing them fast is an important part of managing a session. With the PDF one could just make cheat sheet and keep them handy but what would be the ultimate way of dealing with this is some Android or iOS app to have them at your fingertips.
Well the guys at Purple Sorcerer Games are doing just that. Not only making an app but apps for iOS AND Android. They have a kickstarter project to raise some funds to get the equipment and capital make the Crawlers Companion. A nice touch is including some of the adventures they wrote for the DCC RPG at various backer level.
