Man, I really wish I knew how to program at all, cause I've had an idea for an app like this! I wanted to make something that had your current crew being tracked with a shorthand list of their powers/abilities (just quickly listed, like fast and quake) as well as a counter for SS and Wounds. I figured it would be for a quick on-the-fly look into what each character could do, and the more advanced players would be able to get away with just carrying a phone, while those of us just starting (me) would still carry all the books to matches.
I hope that you keep working on it cause I'd love to see it in action! (even if I only have an iPhone and wouldn't be able to use an Android app, but it's still nice to see it running)
