![Screenshot of the app][screenshot0]

This app is my **first app for Android** it's old and buggy.

It's purpose was to plot simple functions on canvas.

It supports:
* Basic function plotting
* Searching for function zeros using bisection algorithm
* LUA functions
* Dynamic variables changed via UI
* Saving/loading functions and plots

The application was done with help of **Andengine** and Android Canvas.

# Download

Download and install *.apk* package via this button: [![Download][badge download]][link download latest]

# Building

The project contains **app** directory which can be imported into Eclipse via *import existing Android code*

It also provides Andengine library available in the **andengine-dep** which should be also imported the same way into the Eclipse and added to the build path of the application.

The repository contains Eclipse settings that may be changed for compilation for specific Android versions.
