An iPhone that builds iPhone apps.
Open Apped on your phone, describe an app in a chat, and a coding agent writes it for you in React Native. It bundles the project and hot-loads it into the Apped shell on your phone. You tap Preview and use the app a minute later.
To change something, you open the chat again and say what’s wrong. To take the app out of Apped, Max lets you download the whole Expo project from the dashboard. It’s a standard TypeScript workspace. Nothing about it will surprise a developer.
Not another web app with an app icon.
Most things that call themselves “AI app builders” make a web page and ask you to add it to your home screen. That’s fine for some ideas. It is not what Apped does.
When you describe an app to Apped, it writes a React Native project in TypeScript, pulls in whichever native modules are needed, bundles the code with Babel, and hot-loads it into the Apped shell on your phone. That’s the same stack behind a lot of apps you already pay for in the App Store: React Native with Expo. The animations are native animations, the camera is the camera, and the code that runs is the code you see in the chat.
You can live inside Apped and keep editing by message. That’s the workflow most people settle into. Or, on the Max plan, download the whole project from the dashboard as a zip and open it in Cursor, VS Code, or Xcode. It’s a standard Expo workspace (TypeScript, package.json, the works). You bring your own Apple Developer account and EAS credentials to ship it to the App Store.
What Apped is good at, today.
These are the kinds of apps the agent tends to get right on the first prompt. Copy one into the chat and it’ll have a runnable first version on your phone in about a minute.
Personal trackers
Anything where you log a thing about yourself every day. The data lives on the phone (MMKV), so there are no accounts, no syncing, nothing to sign up for.
- >A habit tracker with streaks and a weekly calendar view.
- >A workout timer for HIIT with a buzz at each interval.
- >A mood journal that plots my week as a line chart.
- >A simple monthly budget by category, with a pie chart.
Notes and reference
Structured content you browse, search, and come back to. Store it on-device with MMKV or SQLite, or back it with a small Hono + Drizzle server if you need it on more than one phone.
- >A recipe book with tags, photos, and a search bar.
- >A flashcard app with spaced repetition and decks.
- >A reading log that scans ISBN barcodes and keeps a star rating.
One-trick utilities
Small apps built around a single device capability: camera, maps, haptics, push notifications, contacts, calendars, sensors.
- >A city guide with pinned places and notes, all on a map.
- >A barcode scanner that keeps a list of the products I own.
- >A metronome with haptic ticks and a tap-tempo button.
Games and toys
Reanimated and Skia are in the toolbox, so you can get a surprisingly long way on simple single-player stuff.
- >A daily word puzzle with a share-image button.
- >A coin-flip app with a realistic spin animation.
- >A breathing exercise with a pulsing circle and haptics.
Anything that needs its own backend, user accounts, shared state between devices, third-party API integrations, or payments is possible but still not reliable enough to call production-ready. Apped can scaffold Hono, Drizzle, SQLite, Zod, and better-auth for simple cases, but you’ll still hit edges.
What’s in the app, if you’re curious before installing.
A chat and a live preview.
The chat is where everything happens. As Apped edits files, each tool call streams into the conversation so you can follow the reasoning. Your preview is always one tap away. Open it, tap around, then pull the chat back up to iterate.
Nothing is lost.
Every message and every file version is stored. You can scroll back through the full conversation and see what the agent did and when. If it breaks something, explaining what went wrong in the chat is usually the quickest way forward.
Sharing without a server.
Any app you’ve built can be shared with a public link. Other Apped users can open it and remix it, which forks the whole project into their account. People who don’t have Apped yet land on a branded preview page with a download link.
Export is a real Expo project.
On Max, the dashboard at apped.dev gives you a zip of the project: standard TypeScript, package.json, app.config.ts, a README. Open it in Cursor, VS Code, or Xcode. You add your own EAS credentials and Apple team ID to ship it yourself.
Modules and packages, pre-installed.
typed · wiredApped can reach for any of these on the phone or in the sandboxed server runtime without pulling from npm or asking you to run anything. They come typed and wired up so the agent can import them mid-write.

Things that are rough, in plain language.
I’ve been running Apped as a closed beta for months, and there are edges I know will bite you. Rather than hide them, here’s the list. If any of these are deal-breakers for your idea, save yourself the download.
iPhone only, for now.
Android is on the waitlist below. The React Native code the agent writes is cross-platform in theory, but the over-the-air preview pipeline and App Store submission path are iOS-only today.
Accounts and sync are better, but still rough.
If your app needs logins or state across devices, the agent can now scaffold a little Bun backend with Hono, Drizzle, SQLite, Zod, and better-auth. It works for simple cases. For anything production-shaped, I'd export the project and replace that layer with something you own.
No safe place for API keys.
Public APIs work fine from inside the app. Anything that needs a secret (Stripe, a private OpenAI key, a custom backend token) doesn’t have a secure home yet. The workable path today is to export on Max and wire the key into your own build, outside the Apped shell.
App Store submission is on you.
Apped serves a live bundle into its own shell while you’re building. If you want the app in the App Store as its own icon, you export on Max and take it through EAS and App Store Connect yourself. I want to make that part easier; it isn’t there yet.
Single-player, single-author.
No collaborative editing, no comments, no multi-author projects. It’s a tool for one person thinking at the phone.
One person, in a small room, for the love of it.
I’m Jasper. I’ve been writing React Native for a long time and I got sick of the gap between “I have an idea in my head” and “it’s running on my phone.” Apped is the shortest line I could draw between those two points. It’s not a company yet. It’s me, a laptop, a bunch of build servers, and a probably unhealthy number of hours.
If you find a bug, or something obvious is missing, or just off, email me at support@apped.dev. I read everything and I ship fixes most weeks. If the idea of buying a tool from one person makes you nervous, I understand. But that’s also the reason Apped can be opinionated about what it does and doesn’t try to be.
Questions worth answering.
Is the code that comes out of Apped really mine?
Does the built app run on my phone without Apped?
What language is the code in?
Can my app call a third-party API?
How long until the preview runs?
What about Android?
Is my data on a server somewhere?
Which AI model is behind the agent?
Can I roll back when the agent breaks something?
Can I share an app with friends?
Do I need a Mac or Xcode?
How do I cancel?
Pick up your phone. Build an app.
The first one takes about a minute. The second takes less, because you already have the idea.
Waitlist for Android.
The agent already emits cross-platform code. The build and install pipeline is what’s missing. Drop your email and I’ll send one message when it’s ready.
