About

Gummble is a UI design reference library with more than 300,000 real app screenshots, 21,000+ user flows, and design patterns from 1,500+ shipped iOS, Android, and web products. Designers, UX researchers, developers, and product teams can search by pattern, such as onboarding, paywalls, empty states, and settings; by UI copy; or by complete flows. Each screen includes design analysis, and users can save references to collections. Its MCP server lets compatible AI assistants and coding tools, including Claude, Cursor, and Codex, search the library to ground interface design and implementation in real product examples. The free plan offers limited browsing; Browse adds unlimited screens, flows, downloads, collections, and MCP access, while Pro adds Figma export.

About

Animate Your Ideas, Design Better Apps. Principle makes it easy to design animated and interactive user interfaces. Whether you're designing the flow of a multi-screen app, or new interactions and animations, Principle helps you create designs that look and feel amazing. Use Principle in beautiful dark mode and import designs from Figma. There are a lot of things you might want to design: a short animation, a slick interaction, or an extensive multi-screen app. No matter what you're doing, you can do it with Principle. Principle's timeline makes it quick work to illustrate the perfect bounce, ease, and pop. Want to design a totally new interaction? Principle gives you the freedom to experiment without limiting you to pre-defined transitions. It's a breeze to design the flow of a multi-screen app; and when you're done you'll have a bird's-eye view of all your screens. With artboards, magic animations and a timeline, using Principle will give you Déjà vu.
