Dual-Calc 4+

Dual-Calc is an efficient, simple and easy-to-use calculator app that combines two calculators into one.
The two calculators are sharing one input keyboard and the calculation process and results are displayed in two separate windows.

This calculator is especially suitable for the following use scenarios:
1. Comparative calculation (for example, when shopping online, we want to calculate and compare the unit price of the same commodity in different stores);
2. A complex mathematical operation in which some expressions in the middle need to be operated first. Through this app, one calculator can calculate the main formula, and the other one can calculate the subformula. The result of the subformula calculation can be directly output to the main formula calculator.
3. Dual-Calc has more powerful functions and more reasonable experience than the system calculator, which can completely replace the system calculator.
