The RIGID Digital Bubble Level is more of a novelty app than anything else, but it's actually quite cool and can be useful to some in certain areas. This free app provides you with a horizontal, vertical and angle level using your BlackBerry PlayBook. Use it to straighten out pictures when hanging or leveling up those backyard projects. There is an audible alert for those times when the level isn't in your view as well. Just start leveling and you'll hear a beep letting you know when you're straight as an arrow. The other cool feature is the camera level - letting you view through the camera with a set of crosshairs for those hard to do leveling projects. Overall a pretty neat app and the price is right. Grab it free from BlackBerry App World.
