Scientific Calculator Classic

This free scientific calculator offers a number of useful features allowing you to carry out advanced calculations. Its simple and intuitive design makes it a pleasure to use. The calculator has all the functions that would be expected of a basic scientific calculator and a number of more advanced features too, including complex numbers and logic functions.

The calculator is customizable allowing you to change the colors of the screen, background and all the individual buttons, allowing you to personalize its appearance.


A fully ad free version of this app is also available.
