iCalc is a simple and easy-to-use calculator app for iPhone. It functions like a real calculator, following the same operations as calculators from company C. With iCalc, you can perform arithmetic calculations, root calculations, constant calculations, and independent memory calculations.

One of the unique features of iCalc is the display of calculation history and formulas. After each calculation, the result is displayed on the main screen with a white frame. If you want to perform another calculation without using the [=] key, simply tap an operator key, and the operator will turn white, indicating that you are preparing for the next calculation. The calculation formula is also displayed below the main screen, giving you a clear view of your calculations.

iCalc also includes convenient features such as the ability to erase the minimum digit of the displayed input value by flipping the main display, as well as the option to erase the value in the independent memory by flipping the MR display. You can access the calculation history by tapping the [▼older] key, and if you need to go back to newer history, you can use the [▲newer] key.

In addition, iCalc offers percent calculations for various scenarios. For example, you can easily find out what is 25% of 100, what is 25% of a certain number, or what is the result when 100 is increased or decreased by 25%. iCalc also provides copy and paste functionality for easy transfer of numbers to other applications.

Please note that the calculation range of iCalc is from -999,999,999,999 to 999,999,999,999, and the maximum number of digits is 12. The developer, Takao Ichimura, assumes no responsibility for any loss or claims by third parties that may arise from the use of this app.

Thank you for using iCalc.
