If you happen to be in Texas for Super Bowl XLV, it's worth your time to download the official app for the Super Bowl. While you could cobble together the same functionality from Google Maps, Yelp and a few other apps with food, travel and event info, why bother? The Super Bowl app is free and offers some pretty useful information.
First, you will want to be on Wi-Fi for the initial opening of the app, as it will download all the mapping info on first run. After that, you'll have a 3D map of Cowboys Stadium in Arlington and buttons that will highlight area events, places to eat and more. You can use two fingers to rotate your 3D view, but the 3D is a bit of a gimmick, and this is no GPS app.
Points of interest are filled with live data, and I found the Super Bowl events to be interesting, as you'll want to find real, live parties before, during and after the game. There's also a usable search tool, which you can see in the gallery -- I used it to find local pizza places. Be sure to pull down menus for Dining, Nightlife, Shopping and Entertainment to see what's open at a given hour, or sort by price. You can tap on certain buildings to see what's there as well. During the game, when you're actually at the stadium, you can "enter" the 3D stadium to see gate, elevator and restroom locations.
