Features make calculator an appealing alternative to iPhone’s built-in tool

by Dan Frakes, Macworld.com

Back in October of 2005, I enthusiastically reviewed PCalc 3, which has since been my favorite calculator for the Mac. The developer, TLA Systems, recently released the $10 PCalc for the iPhone and iPod touch, and it’s similarly slick. Although Apple updated the iPhone’s built-in calculator app considerably with the release of the iPhone 2.0 software—most notably by adding a landscape-mode scientific layout—PCalc is an appealing alternative, offering a compelling combination of advanced functions, useful conversion and constant features, and a great interface.
