If you are looking for a graphing calculator with powerful features that is also easy-to-use on phones and tablets, which do not have a hardware keyboard, this graphing calculator is made for you. When using this calculator, you do not have to switch between different scientific and graphing calculators; both are integrated into one. Moreover, it leads you to the required results with the least number of clicks.

Since Android devices come in many different sizes, this graphing calculator also provides a way to customize the user interface (including changing of font size) to fit your devices' screens perfectly

• Graph functions, parametric equations and point sets using Cartesian or polar coordinate systems.

• Curve fitting and least squares lines: When plotting a point set, the graphing calculator can also find and graph the polynomial of the least degree containing all the points. It can also find and graph the least-squares line - which best fits the given set of points. Or, you can just connect the points with straight lines to form a polygon, for example.

• Generate table of values for functions and parametric equations.

• Calculate definite integral, area under (or enclosed by) the graphs of functions (or parametric curves) and arc length in both Cartesian and polar cases.

• Calculate expressions containing complex numbers, such as, (2-3i)^i+5∠(π/4). You can use i or j for the imaginary unit. The result is given in standard, polar and other forms.

• Choice of scientific, engineering and fixed point notations.

• Choice of background color for the calculator.

• The calculator also provides a very useful and intuitive units converter for converting units of mass, length, time and many more quantities.

When viewing the Graphs:
• Touch Polar on the upper right corner of the graphing area to draw the graphs in polar coordinate system.
• Drag the graphs. To center the graph on the screen, touch the coordinate indicator on the top left corner of the graphing area.
• Touch ++ or -- on the lower right corner of the graphing area to zoom in or out.
• Touch the lower left corner of the graphing area (where the caption is) to reset zoom.

You can use the following in your expressions

• Basic algebraic operations

• Power functions

• Trigonometric functions and their inverses (RAD, DEG)

• Hyperbolic functions and their inverses

• Exponential and logarithmic functions

• Factorial, the Gamma function Γ and Psi function Ψ.

• Absolute value and Step functions.

Syntax( by examples)
The graphing calculator, for convenience, automatically appends a default interval to function and parametric expressions and graphs or does calculations over the interval. You can change the endpoints of the interval, of course.

• Function: f(x) = xsin(2x) intvl=(-∞, ∞). (You don't have to type in the interval 'intvl=(-∞, ∞)'; the graphing calculator appends it when you press the graph button. You can change the end-points as desired.)

• Parametric: p(t) = 3cos(3t), 3sin(2t) intvl=(0, 2π). (You can use x for t.) Note: enter x(t) and y(t) separated by a comma (no enclosing parentheses around p(t) ).

• Point set: 1,2; 2,3; 4,5; Note: enter the point (x,y) as x,y;

All of the above with more details are included in the built-in Instruction menu accompanying this graphing calculator.

    I really like the points entry option. I cannot however figure out how to get the calculator to accept a negative number this way. I keep getting the error of invalid operand. I am using the minus sign as I do not see a negative sign. Maybe it's just me. Good app other than that.

    Is there a way to have the tables for the graphs. It would be much appreciated if I was told how to do it

    Its the first app that can graph 2x/(x-floor(x)-1) & other hard graphing functions
