War Room works like a charm on my iPad; I really enjoy having a complete card library with me with rules reference for random stuff I want to look up. Damage tracking is pleasantly easy and well done.
However it doesn't work at all on my Droid, constant crashes. iBodger did a better job at being a pure list-building-machine, but I feel like in the end WR will surpass it simply with all the other things it can do... once the kinks are worked out.
I like it, and I'm cautiously optimistic about the potential uses. Right now, though, it is a bit lacking in polish.
