Having two calculators together can serve you multiple uses. For example, to perform two calculations at the same time and in this way simplify certain procedures; or to create two lists of additions. But really, you yourself will realize with its use that the double calculator function can be used for many more calculations than you thought. And who knows, maybe the double calculator will become your main calculator.

The design is clear and precise, with large buttons for pleasant use. It's easy to tell the two calculators apart because each is a different color.

Both calculators have the basic functions: addition, subtraction, multiplication, division, remainder, and negative numbers. Depending on the orientation of the device, the dual calculator adapts to portrait and landscape mode.
