About Stacky

Stacky is a convenient, easy-to-use pocket calculator. The great advantage of Stacky is that it lets you organize numbers in a stack, and all mathematical operations are performed on the numbers at the bottom of the stack.
Stacky allows you to easily deal with multiple numbers at the same time, which is often hard to achieve with other calculators!

Stacky offers many helpful features including the following:
- All important mathematical functions are readily accessible by swiping once on the numeric keypad.
- Two numbers can be entered together by putting a space between them for quick computations.
- Any number on the stack can be copied by simply touching it.
- Swiping over a number negates it.
- The entire stack can be erased by shaking the device.
- Any operation can be undone at the touch of a button.

Moreover, there is a variety of themes to choose from according to your personal preference.
Last but not least, Stacky works on all your iOS devices!
