Complex Function Viewer (Conformal Maps)

Enter any equation of variable z and produce a complex function graph (conformal map) generated with domain coloring right on your device!
Notable features include:
Extensive and easy-to-use touch interface.
Over 50 mathematical functions, including special functions like gamma, iterated functions, lambert-W, and Riemann-zeta.
Images on the complex plane (conformal mapping of images).
Contour integration (drag a path), derivatives, and function values.
Save, load, export, and import your favorite equations.
Save images, view your saved images, and later load the specific equation and bounds back into the app for more exploration.
Many customizable settings.
A tutorial to familiarize you with the app and example equations.
Complete documentation within the app available through the "about" menu.
Easily give feedback.
Useful for complex analysis.
