Plaid is an Android app built to showcase material design, a set of visual and interaction guidelines from Google that emphasizes bold colors, smooth animations, and clean layouts. The app pulls design news and inspiration from several online communities, giving designers and developers a single place to browse fresh creative work. Beyond being a content feed, Plaid exists primarily as a reference implementation. If you're building an Android app and want to see how material design principles are applied in a real, working product, Plaid is meant to show you exactly that. It demonstrates how screens, transitions, and UI components should look and behave when material design is done well. The project has also been used by Google engineers to demonstrate modern Android development practices. Plaid 2.0 is a rewrite focused on converting the original codebase to Kotlin, a modern programming language for Android, and adopting Architecture Components, a set of libraries that help organize app code into modules that are easier to test and maintain. The README describes goals like modularizing the app using dynamic feature modules, which means splitting the app into independent pieces that can be loaded on demand, reducing the initial download size. The project notes it won't change visual design elements, the styling work was done in the original version, and the rewrite is purely about code structure improvements. It is open-source and licensed under the Apache 2.0 license.
