Woodworking Calculators app for iPhone and iPad

Woodworking Calculators is a collection of utilities designed especially for woodworkers. The main principle of the application is the ability to enter measurements just as you would read them from a tape measure, perform the calculations, and then have the answers provided in a format that is also found on your tape measure. In addition to the main calculator, there are also special purpose calculators, a board feet calculator, and a pilot hole guide.
