Here is a very simple app on the iPhone that is one of those things that is just ingenious.  The app is called Level and as the name says….  It is a Level.  You know one of those things that have a little air bubble that is in the center when it is level?

Start up level and turn the iPhone lengthwise or leave it standing up and you will get a level with a little bubble.  Using the built in accelerometer in the iPhone, the Application can determine what angle the iPhone is at.  It tells you the angle in degrees as well as a virtual level on the screen.

Oh, and there is more.  Set the iPhone on a flat surface facing up and you have another level.  This is a round bubble level.

So next time you are handing that new picture, no need to run to the garage and try to find that level, reach for your electronic best friend, your iPhone.
