Developed by Florida woodworker Norman Lucia for his own use, the Argyle Cabinetry AngleCalc and RadiusCalc software applications for iPhone, iPod and iPad devices are designed for easy calculation of angles and radii used in woodworking and do-it-yourself projects. RadiusCalc will calculate circle circumference and arc segment length and area, while AngleCalc measures and calculates angles and miters of any degree. A miter box field shows the accurate setting for your calculated angle, with warnings about miter box angles greater than 45 degrees and recalculation for use with a 45 degree fixture fence. ArgyleCalc offers the combined features of the AngleCalc and RadiusCalc apps, as well as the ability to input CAD information and make calculations for fluted columns and moldings. The AngleCalc and RadiusCalc apps are each priced at $2.99; ArgyleCalc is $7.99.
