I use the Chip Guide to tell me what casinos are in the areas that I am visiting (even to the point of planning side trips to hit some). So if there were an app, I would want to be able to look up casinos by state, city and status (open, closed).

Also, it would be nice to be able to see what chips you have listed for a casino. That would be nice for when you are picking up chips from shops and sales. It would be nice to know what chips are the "Current" chips being used at a casino. I know that the online version of The Chip Guide doesn't do that, but it would be nice to have.

Another also for me would be to have access to the casino's website links. Always nice to be able to jump to a casino's website to ensure it is open. All the closing due to mother nature can cost lots of gas money.
