How it works

Write a screen, see it on your phone, then put it in the stores

Each tag in HAM is a component built into the Hype Apps app. You choose the components and arrange them; the app draws them as native screens.

Write a screen

A tag for each part of the screen, and words for its look. This is the greeting at the top of petBlue, an example app: a pretend airline for pets.

<!-- The navy hero -->

    <text style="text-white
            font-size-30 font-light">
        Good morning, Biscuit
    </text>

See it on your phone

In the Playground, press Publish and you get a five-letter code. Type it on the home screen of the free Hype Apps app, and the screen is on your phone.

New to building apps

  • Nothing to install: the Playground works in your browser.
  • HAM looks like HTML: a tag for each part of the screen, and words for its look, like text-white or rounded-lg.
  • In the Hype Apps app, press and hold any screen to see the HAM that built it.

You build with AI

  • The whole HAM reference is public at hypeapps.dev/llms.txt, so any agent can write HAM for free.
  • Your agent writes HAM; the screens are native components built into Hype Apps, not a web view.
Open llms.txt

You're a developer

  • Markup over native components, with htmx-style swaps, Alpine-style state and Tailwind-style classes.
  • An OpenAPI spec, the Playground API and an agent skill.
  • How HAM fits the App Store's rules is in the FAQ.

What HAM is

A markup for arranging the app's own components

Native components, built in

Every tag is a component that ships inside the Hype Apps app: text, lists, cards, buttons, forms, the camera, motion sensors and local storage. Not a web view.

Change it, and the phone follows

Your screens come from where you keep them. Edit and save, and the phone shows the new version. New kinds of components arrive with updates to the app.

Familiar if you know the web

HTML-like tags, and Tailwind-style classes for the look. If you've never written either, start in the Playground: change a line, publish, and see it on your phone.

What you need

A browser for the Playground, and the free Hype Apps app on an iPhone, iPad or Android phone. Supported devices
