This is a really great start for an Arkham Horror game aid. A few thoughts that would make it better:
- tracking more details for the investigator than just stamina, sanity, clue tokens, and money, such as injuries, madnesses, skills, etc.
- showing the actual value of die rolls. Although the app does allow you to specify blessed or cursed status for what constitute a success, there are several game elements that rely on the actual value of the die (roll a 1 to do x, on a 6 you do y, etc)
- tracking overall game stats, like terror track, doom tokens, monster limit, etc.
