  • A meal planner for my family
  • A tiny invoice helper for my shop
  • A weekend trip planner
  • A flashcard game for my kid
  • A journal for my garden
  • A scorekeeper for board-game night
  • A calm habit tracker
  • A menu for my café
  • A marble maze in 3D
  • A packing list we can share

From one sentence to an app on your Home Screen.

  1. Say what you want.

    Type it the way you’d explain it to a friend. “A meal planner for my family.” “A tiny CRM for my bakery.” Add a sketch or a screenshot if it helps.

    Juno’s home screen on iPhone: “What would you like to make next?” with a prompt box and suggestions like Trip planner.

  2. Watch Juno build it.

    Juno plans the screens, writes the code, and runs your app as it goes, checking its own work along the way. Every step is explained in plain language.

    Juno on iPhone explaining how it will add a Map tab that plots every saved place, in a conversation sheet over the app being built.

  3. Point at what to change.

    Tap anything in your app and say what you’d like instead. “Make these photos square.” “Remove this line.” No jargon needed. Juno knows exactly what you mean.

    Juno on iPad: two text elements in the app preview are selected, and the request reads “Remove these texts from the screen.”

  4. Keep it. Share it.

    Your app is ready to use the moment it’s built. Open it like any other app, send a link so friends can try it, and publish to the App Store when you’re ready.

    Sharing your apps is always free.

    • Spotlight
    • Siri
    • Widgets
    • Share links

Real apps. Not web pages in disguise.

Juno builds with the same native building blocks as the apps already on your phone, so what you make scrolls, taps, and feels like it belongs there.

  • Native controls

    Lists, tabs, sheets, and buttons that behave the way iOS should.

  • Maps & places

    Real maps with pins, places, and directions built in.

  • Photos & files

    Pick images, attach files, and keep everything saved on device.

  • Games & 3D

    Playable games and 3D scenes with physics, haptics, and scores.

Talk it through, or open the hood.

Never written code? Perfect.

Juno was made for people with ideas, not programming degrees. Ask for changes in your own words and review the result in a live preview.

Can the habit list show a little streak next to each one?

Added a streak count beside every habit. It resets if you miss a day. Take a look in the preview.

Write code? It’s all there.

Every project is real TypeScript and JSX that renders as native SwiftUI. Open the editor, change a line, and see it run instantly. Or ask Juno to explain any of it. 

import { VStack, Text, Button } from "@juno/ui";
import { useState } from "@juno/runtime";

export default function Tally() {
  const [count, setCount] = useState(0);
  return (
    <VStack spacing={16} padding={24}>
      <Text fontWeight="bold">{count}</Text>
      <Button
        title="Add one"
        onPress={() => setCount(count + 1)}
      />
    </VStack>
  );
}

Questions

Good to know.

Still curious? Browse the docs or write to support@buildinjuno.com.

Do I need to know how to code?

No. Describe what you want in plain language and keep refining with follow-ups. The source is always there if you want to look at it or edit it yourself, but you never have to.

Do I need a Mac or Xcode?

No. Juno runs entirely on iPhone and iPad. You describe, build, preview, and refine your app on the same device you use it on.

What kinds of apps can I make?

Everyday tools, journals, planners, trackers, helpers for a small business, games, and 3D experiences. Juno shines at personal apps and apps for a small group of people. If you can describe it, it’s worth a try.

Are these real native apps?

Yes. Juno builds your interface from native iOS components and runs it live on your device, not as a web page or a mockup.

Can I share what I make?

Yes, and sharing is free. Publish an app from Juno and send the link. Anyone with Juno can open it, and it shows up in their Shared tab. You can also launch your apps from the Home Screen, Spotlight, Siri, and widgets. How launching works.

Can I publish to the App Store?

Yes. Juno’s web console handles App Store publishing for synced apps through your App Store Connect account. Apple requires your own Developer Program membership, and you stay in control of the final submission and release.

How much does it cost?

Juno is free to download and free to get started, and sharing your apps is always free. Building with Juno’s AI uses credits, shared across all your projects. Get more with a subscription or a one-time top-up in the app. Prices are shown by the App Store. More about credits.

What happens to my data?

Your projects belong to you. Juno explains exactly what is sent to its AI providers before you start, and asks for your consent. Privacy and AI data.

Your next app starts with a sentence.
