Graphic calculator, free and with no ads displayed on the main graph screens.
Super fast algorithms allow scrolling and zooming of 2D graphs in real time, using the touch sensitive screen.
3D graphs can be calculated quickly and then viewed from any angle.
Graph implicit equations in both two and three dimensions. e.g. x²+y²=5² or 5x+2y-3z=15.
Graph implicitly defined inequalities in two dimensions. e.g. 2x+5y
