Doodle helps you create beautiful, modern apps entirely in Kotlin. Its render model is intuitive yet powerful, making it easy to achieve complex UIs with pixel level precision and layouts. This simplicity and power applies to everything from user input to drag and drop. Doodle lets you build and animate anything.

Start creating your app for Web and Desktop; just define your View hierarchy and business logic, and go.
