ModiCal - Intuitive calculator

A calculator app gentle with human.
Even if you make a mistake, even if you forget calculation, it's OK.
Once I have optimized the calculator for the smartphone, "AC" and "=" are the same.

I can not use the memory buttons, such as "M +" and "MC".
and often re-calculated from the first. because input mistake or forget where to do was calculated.

This app created from "The calculator for me" concept. There are the following features.

2, It will use the previous calculation result as an input value.
3, You can correct the mistake later. (it will be automatically re-calculation.)
4, It is enclosed in parentheses by grouping rows.
