Compose Material Catalog

A working reference for Compose UI

Compose Material Catalog is a demonstration app for Android developers using Jetpack Compose. It presents Material components as interactive screens rather than as isolated documentation, making it useful when you need to check how a component looks, behaves, or responds to different themes before adding it to an app. It suits developers learning Compose as well as experienced teams checking implementation details.

Useful to browse, easy to test

The catalog groups components and examples into a straightforward browsing experience. Selecting an item takes you from a general overview to a closer look at the relevant control or pattern, while interactive examples show states and behavior that screenshots cannot. That makes it more practical than a static gallery, particularly for controls whose appearance changes with input or state.

Good for visual decisions, less useful as a full guide

Theme controls, including light and dark presentation, give developers a quick way to inspect contrast and surface choices. The app also demonstrates the Material system through its own interface, so its layout provides a useful example of Compose in practice. The limitation is scope: this is a catalog and reference aid, not a substitute for API documentation, design guidance, or a complete tutorial. Its value depends on already knowing what you are looking for.

Verdict

Google LLC has made a focused tool for a specific audience, and the 100,000+ installs suggest it has found that audience. The 3.8536584 average from 857 ratings points to a helpful but not flawless reference. Compose Material Catalog is worth keeping nearby during UI work, especially when comparing components directly, though newcomers may need other resources to understand the underlying framework.

Score: 3.9/5
