With less than a week to go before Apple officially releases iOS 7, PCalc has just been primed for the upcoming software through its 3.0 update.

Indeed, the latest update to the highly rated iOS calculator app brings full support for iOS 7. What’s more, it introduces a new minimalist look that’s in accordance with the design aesthetics of the upcoming software update.

Specifically, PCalc now has a new default iOS 7 theme called Samurai. But don’t worry, the other themes are still available for you to choose from if the flat design movement is not really your cup of tea.

PCalc 3.0 also adds support for speaking actions and results on iOS 7 and for using dynamic type on iOS 7.

But it’s not all iOS 7 this and iOS 7 that. On the contrary, the update also delivers a number of improvements beyond its focus on the latest version of Apple’s mobile operating system.

For one thing, it brings a smarter display for iPhone that uses bigger font sizes when showing fewer lines of data.

For another, it adds a couple of new layouts on iPhone that let you have the tape permanently on-screen. It now also lets you launch PCalc from other apps with a specific layout through the app’s custom URL scheme, pcalc://layout/name.

In addition, PCalc 3.0 includes the following enhancements:

  • The tape now shows all operations including functions, conversions, and constants.
  • Added new digit display options.
  • Added “Gas Mark” to the “Cooking” section of the unit conversions.
  • Added an option for constant functions in algebraic mode – press equals to repeat the last calculation, or enter a new value and then press equals.
  • Added an option to greatly increase the size of the text on all buttons.
  • Added an option to hide the status bar.
  • Added an option to switch off all animations.
  • Added an option to switch off changing the number of display lines by swiping.
  • Added a button to change all settings back to their default values.
  • You can now double-tap the 2nd button to lock it in the on position.
  • PCalc now inserts an implied equals if you start entering a new number mid-calculation.
  • On the phone, tapping the display at the bottom while in settings, conversions etc. will quickly return you to the main calculator.
  • Fixed a problem with user constants not syncing correctly via iCloud.
  • Fixed a crash when editing functions and conversions.
  • Improved startup speed.

PCalc 3.0 is available now in the App Store as a free update or as a new $9.99 download. The app is compatible with iPhone, iPod touch, and iPad running iOS 6.0 or later.

PCalc is listed as a “notable app” in AppAdvice’s Best Calculators for the iPhone AppGuide.
