I've just published new mobile app named "A. H. Tracker" to simplify tracking of the Arkham Horror LCG - board game. I wrote it to help me to play without tokens, paper and pen. It is helpful especially when you want to take just cards, and play with your friends somewhere outside. In my case usually on weekend stay.
