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.

It seems that implicit plot has problems handling transcendental equations like "sin(x*y)= k". It might be a good idea to add a warning about that. EDIT: You are right, there is no problem at all. The calculator was in Degree Mode. Changing it to Radian Mode makes everything behave as I was expecting. Thanks for your hard work on the calculator and for the response!

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.

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!!!

It's a really nice and useful app with plenty of functions. I installed it because I wanted to calculate probability distribution. So I would have rated 5 stars if I was not frustrated by th confusing (if I dare not say wrong) results of normal distribution calculation. Test it many times with different cases. All completely different results as standard results. Hopefully Philip can explain the problem. Thanks. Update: just received Philip's quick reply. A really responsible programmer. 5 stars

This is BY FAR the best scientific calculator I have come across. This is the best calculator you can find short of buying a Texas Instruments one for an absurd amount of money. Its free, easy to understand, and reliable. Thank you so much for this, my only regret is that I don't have the money to buy ad free (college student).

An excellent calculator but it's missing a few features. For example: how can I calculate an indefinite integral? Also, when graphing functions in the 2-D graph, I can't seem to find a way to graph a double or a triple function. Also, I can't graph any functions with conditions to it. EDIT: I understand why you didn't put indefinite integrals, but how about graphing double or triple functions? Also, adding domains to the functions is very important in graphing.

I really like this calculator. But it has one grave problem: The integrate function does not work for some functions. Example: x⁻² integrated from 1 to ∞ equals 1 but the calculator prompts diverging values when putting in increasing upper limits and prompts 'undefined' when you put in ∞. This also happens for other integrands with negative exponent. As I deal a lot with such kinds of integrals, this is very unfortunate. Fix this, add some way of saving natural constants and I'll give you 5/5!
