If you’ve done a few home improvement projects, you probably either ended up with more materials than you needed . . . some of it cut and ruined in little chunks all around your feet . . . or you had to run back to the lumber store for more. Either way, it’s not efficient and it’s mildly embarrassing. Cut Calculator comes to rescue by letting you enter in the amount of pieces you need . . . and the size of your cut-able material (a board or sheet of plywood, for example). Then it shows you how to cut it all up so that you maximize your cuts and waste little. Or complete the project. For details, check out my review at MacNewsWorld.
