About this app

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 scientific calculator and a number of more advanced features too, including complex numbers and matrices.

The super fast algorithms allow the scrolling and zooming of 2D and 3D graphs in real time, using the touch sensitive screen.
Graph implicit equations in 2 and 3 dimensions. e.g. x²+y²+z²=5².
Graph inequalities in 2 dimensions. e.g. 2x+5y<20.
Graph functions of a complex variable.
Display up to 5 graphs on the same screen.
Active analysis of functions, for better graphing of 2D functions with singularity points. e.g. y=tan(x) or y=1/x.
Intersections on 2D graphs.

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.

Ratings and reviews

I'm using this app from an year, and regret that I didn't find it sooner. The app is simply awesome and I feel like small improvements can be made to do it better. Like solving linear and quadratic equations. Its taking a lot of time to fill both the variables and constants and that could be made better by giving blanks to the constants, it will be easier for calculation...

This is the very best calculator ever. The description of the app by the author does not point out the half the cool stuff. I even persinalized each button!!! Menus are intuitive, easy to use, without unnecessary steps. I just ask to developer to include the switch between binomial and polar complex form in some button instead in the lateral menu. Any case i love the app!!!

I am using this for over a month and this is fantastic. To check the power of this calculator, I entered a hard integral problem. It took a minute and exactly found the answer. One request to the developer is that you should add limit of x,y tending to a,b that means two dimensional limit. It will be extremely helpful. Graph is not the best quality. I entered the general equation of a circle and it showed no graph. Scientific calculator is best. Better than any other app.
