TLA Systems has released PCalc 4, rewritten from the ground up to resemble its iOS sibling. The latest version of the powerful Mac calculator includes a number of new features, such as the capability to show multiple lines on the display; a “ticker tape” option to show a history of recent calculations; editable user functions and conversions that sync to iOS and other Macs via iCloud; smart searching for conversions, constants, and functions; enhanced AppleScript support; and more. PCalc 4 requires OS X 10.8 Mountain Lion and is a free update for both Mac App Store users and those who purchased PCalc 3 from Kagi after 1 April 2013. It’s now being sold exclusively through the Mac App Store. ($9.99 new on the Mac App Store, free update)
