kivy doc

Kivy is an open source Python library for developing multitouch application software with a natural user interface (NUI). It can run on Android, iOS, Linux, OS X, and Windows. Distributed under the terms of the MIT license, Kivy is free and open source software.
Kivy is the main framework developed by the Kivy organization,[1] alongside Python for Android,[2] Kivy iOS,[3] and several other libraries meant to be used on all platforms. In 2012, Kivy got a $5000 grant from the Python Software Foundation for porting it to Python 3.3.[4] Kivy also supports the Raspberry Pi which was funded through Bountysource.[5]
The framework contains all the elements for building an application such as:
extensive input support for mouse, keyboard, TUIO, and OS-specific multitouch events,
a graphic library using only OpenGL ES 2, and based on Vertex Buffer Object and shaders,
a wide range of Widgets that support multitouch
an intermediate language (Kv)[6] used to easily design custom Widgets.
Kivy is the evolution of the PyMT project, and is recommended for new projects.[7]
