Shift Calc app for iPhone and iPad

Shift Calc is a calculator which has big buttons, and a shift button to switch to the second screen to input operation buttons.

Because of the big buttons, its very easy to input numbers, even though you need to push a little more button.

Especially, if you put your iPhone on the desk and use it as a calculator, then you would soon realize that you could put only 3 fingers on the screen of your iPhone.

Thats why Shift Calc has only 3 big buttons on the horizontal dimension. Its very comfortable to push buttons without paying too much attentions.

You can also review the history of input and calculation.

I use it everyday for my job as an accountant. Now, its your time.
