Drywall Calculator Jeremy Breaux Price: 99¢Platforms: iPhoneThis app makes relatively simple calculations even simpler. To figure out how many sheets of drywall will be necessary for a given room, all the user has to do is input the height and perimeter of the walls and the length and width of the ceiling. The tool can exclude some areas of the room and allow for slope. The app gives total drywall area in square feet and tallies the number of 4-ft-wide by variable-height sections needed. Users must enter fractions as decimal points, which one app reviewer thought preposterous. n9/11 MemorialNational
