It shows the Homeland Security info like threat level (color codes, though we abandoned that though) as well as airport statuses via lookup. It also has links to the Department of Homeland Security websites for quick reference. But really, it's the color coded Live Tile that's kind of cool here--even though it is set to expire in April.
The app has been out for awhile now and fetches for $0.99. While it is nicely done and works well enough, we can't help but think it's not much use either, especially after April. But if you're the "I own a bunker" type, then we got you covered. No trial. Grab it here in the Marketplace.
