Walk on the trace of the mythic Egyptian and Maya civilizations with PlumbString. Use the tool that allowed them to build incredible edifices, but now in a handy and hi-tech way ! Just place your iPhone/iPod Touch on your walls to check if they are perfectly up-right. See how far move the plumbString from the origin position, and check the digital angle value ! Correct the error of your accelerometer with the calibrate button !
Take your iPhone/iPod Touch up side down in your palm, slightly rotate it (to the left or the right) and transform PlumbString into a fake detector !
