Explain
Kivy uses Python for app logic and KV language for UI design.
It includes a full widget toolkit, layout engine, GPU-accelerated rendering using OpenGL ES2, and support for multitouch events.
Kivy is widely used for mobile apps, touchscreen kiosks, prototypes, educational tools, and Python-based cross-platform GUIs.
