What is Sketchware?

Sketchware is a visual programming environment designed to help users create Android applications without needing to write complex code. It uses a block-based system where each block represents a different action, logic, or command. Think of it as a way to build an app with blocks that snap together to form your app's behavior.

Key Features of Sketchware:

• Visual Interface: Build your app by dragging and dropping blocks.

• Java & XML Support: For those who want to get more technical, Sketchware allows you to write custom code in Java and XML.

• Real-Time Preview: Preview your app in real-time as you build it.

• Community Support: Access a vast community of developers for help, resources, and tutorials.
