Fantasy Flight Games has released Arkham Horror Toolkit — an iOS app for Arkham Horror designed to take care of some of the overhead with playing that game,
The app has gotten fairly good reviews, but one of the issues to be cognizant of is that buying the $2.99 app give you the toolkit for managing investigators, locations, etc. for the main game but not for the various expansions.
To enable the expansions in the app, the user has to enable each of the expansions with an in-app purchase. Full blown expansions, such Dunwich Horror, are $1.99, while smaller expansions, such as The King in Yellow, are $.99. Still, if you want to enable all of the expansions, you’re looking at a total cost of $12.92.
Seems kind of steep, but on the other hand I know if they had an Android version of this I’d pay that in a heartbeat.
