Welcome to StackCalculator!
StackCalculator features a solid and mechanical look and feel, reminiscent of the classic HP calculators of the past.
It is not meant to compete with spreadsheet programs, but rather to offer a simple and efficient alternative for everyday calculations. With our app, you can perform basic arithmetic operations.
StackCalculator features three simple screens:
Calculator: This screen offers two views - stack view and edit view. In the stack view, you can see the current state of the stack and perform calculations using the stack-based approach. StackCalculator allows you to have up to 99 stacks, each with up to 99 items, and each item can be referenced by its position in the stack. You can also name each item as a variable, and all variables are global. The first item in a stack is called 1.
Functions: This screen is a menu-driven calculator that offers a wide range of functions, including basic arithmetic functions. You can access this screen by clicking on the "Functions" button on the Calculator screen. StackCalculator also allows you to use pre-existing calculations from the menu to perform complex calculations quickly and easily.
Menu: This screen provides control setup, export, and other options. You can access this screen by clicking on the "Menu" button on the Calculator screen.
With StackCalculator, you can quickly and easily perform all your calculations on-the-go, without the need for complex spreadsheet programs.
