Now you can make your iPhone into an all-in-one carpenter toolkit. The iHandy Carpenter contains a plumb bob to determine the verticality of lines and walls, a surface level, bubble level bar, steel protractor and steel ruler. Priced at $1.99, it's got to be the most affordable set of tools I've seen in a kit.
i have this the iHandy Carpenter app but can't figure out how to actually use it. How does one actually measure anything longer than the ipod itself using the ruler? I can scroll along for as long as I want, but can't measure anything. does anyone know?
