Not only does it track traits, it reveals the haunt based on the item and the room and gives you the trailers tome and the survivors handbook for the haunt in question. They really went above and beyond for this one.

I've looked into it a bit more. Looks like the one I use is not the official app. But I really like it much better then the official app.
