A structured reference for native app design.

Everything a design team needs to make great iOS apps. Components, patterns and foundations, explained with examples from real apps.

Beyond the guidelines.

234+ screenshots from real apps, and counting.

More examples
More content and more screenshots than Apple’s Human Interface Guidelines, from Apple’s own apps and others, in light and dark.
Only native
Every example is from a native iOS app. No web apps, and no cross-platform apps.
Always up to date
Made for Liquid Glass, Apple’s new design language. When Apple ships a new iOS, we update the content, so you don’t have to keep track.
Where you work
Connect 234 Native to Claude, Cursor or other AI tools over MCP, and get up-to-date knowledge in the tools you already use.

234 Native Companion is an iOS app where you can try the components live on your own phone, and export the code.

Be among the first to use it. Leave your email, and we will let you know when 234 Native opens.

We also made Duo Gallery, where you can see how apps look on iPhone Duo, screen by screen.
