BaldGeeks have announced the release of Geo-Calc 2.0, a major update to their comprehensive geometry calculator for Mac OS X. “Geometry problems are common in a variety of situations, from construction, modeling and design, to DIY (such as estimating the quantity of carpet, paint, or titles required). Geo-Calc makes easy work of these sorts of tasks, as well as being a useful educational tool. Aiming to be the ‘Swiss Army knife’ of geometry applications, Geo-Calc has attracted a broad user-base which includes teachers, students, builders, designers, engineers, mathematicians, and even rocket scientists.” Version 2.0 offers: Universal Binary support; tape drawer listing previous calculations; graphics drawer containing a scaled rendering of both 2D and 3D shapes; and improved support for Spotlight. Geo-Calc 2.0 is priced at US$14.99 and requires 10.3.9 or later.
