Love this app. Use it constantly. I can always tell whether the games are going to be good based on the number of tables at a given property, so it helps me tremendously in deciding whether to drive 45 minutes in one direction or another.
This app is awesome. They include details about the room and the phone number of the poker room, so you can call and get on a list if you're on the way there. I use this all the time for things like O8 or other games that typically have few tables and long wait times.
