Beautiful, Simple and Useful.

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.

I'm sold on the interface!

Just opened this on my iPad 4. LOVE the look. Now, I don't do much with a calculator other than multiplying and dividing. So don't count on me to vote on the intricacies of advanced functions.

I look for things like the keys being in the right spots. Well, they are. And it runs a little history on the wrinkled scratch paper next to the calculator. Which is how I keep track when I'm too lazy to open excel.

So, thank you, developer, for the freeness you've provided. Oh, and for creating an app worth investigation and a home on my IOS devices!
