Its been compared to that age old question....What is that app that tells you what song is playing?

If you're looking for a pretty cool simulation game and love trains then N3V Games has built the right app for you!

If you are the slightest bit board with facebook, meaning the way the app looks, then try flipboard.

OK, this app is not for everyone but it came in really handy for me.  Like many other people, I can not sleep without some sort of white noise in the background.
