Calculator Retina HD designed for iPhone/iPad with the best graphic design for retina and non retina display with big buttons and a nice illuminated push effect, including a high quality sound.

This calculator was designed to be the most simple, elegant and efficient as possible, without complicated functions, just enough for everyday calculations.

The calculator also includes a history tape, just tap the screen to open it (if you have an iPad this is not necessary due that the history is at the left side) , you can send your history via e-mail or select and copy.

A backspace function is included too, giving a more accurate functionality than the common "C" key due that digits could be individually deleted while in a mistake.
