Every once in awhile I come across an app that is simple but addicting -- a perfect game to play with a mobile device such as the iPhone. Jetman happens to be one of those apps. Originally finding its home as a gimmicky Facebook app, Jetman was ported over to the iPhone platform quite some time ago by a developer by the name of Mobilisimo. The concept is simple enough: Your job is to guide Jetman through a never-ending tunnel filled with floating bricks. Hit one of those blocks and it's game over. While you technically can't win at Jetman because it's a never-ending experience, I've found myself playing this little gem in the oddest of places simply because it's extremely easy to play a round or two while you're waiting for something. Waiting for a meal at a restaurant, sitting through a lecture, waiting for the bride to come down the aisle at a wedding...anywhere, really. Also of note is that Jetman is not a battery drain at all, making it perfect for on the go gaming. Since this app is free, you really have nothing to lose by checking it out. So what are you waiting for?
