About Dual-Calc

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.

【 Features 】
1. Results can be exported from one calculator to another.
2. For the convenience of users, we provide two ways to switch calculators. The only difference between the two ways is whether the results of the previous calculator are automatically brought to the next one during the switching process:
a. Click on the ⇅(⇋) button, will switch calculator, at the same time the result of the current calculator will be output to the other one.
b. You can switch calculators by clicking the top two calculators directly, but the calculation results will not be automatically output at this time.
3. Provide standard calculation mode under portrait and rotate the screen to landscape it will become a scientific calculator.
4. Long press the calculation result label to copy it to the system paste board.
5. Support 3D Touch to copy the latest calculation result.
