PCalc update for iPhone
TLA Systems has released the latest version of its iPhone calculator app, PCalc 1.0.2. The major improvement for the iPhone edition is multiple undos and redos, initiated by flicking the LCD to the right for the former, and the left for the latter. An "HP style RPN" option has also been added to simulate old calculators, and the general appearance has been enhanced, with more visible keys and customizable LCD color.
The app can be displayed in one of two layouts: one for simple operations, and another for advanced functions. Supported modes include hexadecimal, octal, and binary. Various constants are available in the app, as are tools for unit conversions. PCalc 1.0.2 is available from the App Store for $10. An updated version for Mac OS X will be available in September.
