    touchGrapher is a graphing calculator which lets you draw graphs of many functions at once, manipulate them after they have been drawn and customize their appearance. Silky smooth experience due to full hardware acceleration on ICS+ devices. A function can be added by entering its formula, or by entering a finite number of points, so the function is created using linear regression, exponential regression or polynomial interpolation. You can also search for the functions' zeros, local extrema or intersection points with another function. The plane can be panned freely and zoomed using multitouch.

    I am a Computer Science student interested in Android a lot. I have written lots of applications, some of which have been published, but there is one I am particularly proud of. I have written it entirely on my own and recently publish the PRO version, which, apart from being ad-free, has a lot of useful features.

    touchGrapherPro is a graphing calculator unlike any other. Its highly intuitive interface lets you quickly do things that would normally take a few times as long. A very useful tool for students of Math-related subjects makes you more effective in many tedious tasks.


    Plot graphs of functions, curves, add parameters to them, interpolate a set of points to a function and many more in a matter of a few taps on the screen. Optimized for both tablets and smartphones, the app runs smoothly even on devices from a few years ago. This all makes Maths and analytic geometry as pleasant as never before.

    In the free version of touchGrapher:
    - plot graphs of functions on a plane
    - numerical integration
    - generate functions from a discrete set of points:
    - linear regression
    - exponential regression
    - polynomial interpolation
    - find zeros and local extrema of functions, intersection points of two functions
    - save graphs to image file
    - modify graphs' appearance after they have been plotted

    Extra features of touchGrapherPro:
    - no ads
    - plot curves from parametric equations or in polar coordinates
    - introduce parameters to formulas and adjust them in real time
    - import and export graphs to text file
    - draw complex graphs in seconds from the list of examples(e.g. Lissajous curve, cissoid, and many more)
    - remove single points attached to graphs
    - save screenshots in selectable resolutions and share them instantly from the app
    - unlimited number of graphs at once
    - improved performance
    - refined user interface
