Oh My Cal! is a multifunctional and multi-mode calculator. It's very cool and convenient!

Benefit Highlighting:

• Supports Basic/Scientific/Programmer mode.

• In programmer mode, you can calculate in Decimal, Octal, Hex and Binary and convert them each other.

• Very convenient to use, you can callout calculator in any workspace using the global key combination. And you can calculate the formulas from within the menubar easily without switching among several apps(For details, see the screenshots).

• A black berry flavors UI :-)

You may want to ask: The Calculator.app in OS X is powerful, why should I use the Oh My Cal! ?

The Calculator.app in OS X is powerful, but it's not convenient. For me, I usually use many apps in fullscreen mode( Xcode, Evernote, etc.). Whenever I want to calculate some formulas, I have to switch among several apps or screens. Oh, I really could not stand!!! So I wrote Oh My Cal!. In addition to as powerful as the Calculator.app in OS X, it's very convenient to use (Global Callout or Hanging in menu bar).

• Stability improved.
• Killed some fucking bugs:
  • Lagging when switch OCT/DEC/HEX mode.
  • The Enter, Clear and Equal button on the "Apple Keyboard With Numeric Keypad" all do not work. ( found by Mr. Tobias Kroniger ).
• Support of Pasteboard.
• Supports of Parentheses and more will coming soon!
• Various minor improvements.
• Enjoy & STAY TUNED!
