Free while we're in beta
Your app idea,
on the App Store.
Describe the mobile app you want in plain words. MoBuild builds it, shows it running on a phone, and takes it all the way to the App Store and Google Play. You don't write code and you don't hire anyone.

Built on what real apps are built on
- React Native
- Expo
- TypeScript
- iOS + Android
- Your code, your repo
The problem
Most app ideas die before anyone sees them.
You don't need a co-founder who codes. You need the thing to exist.
Quotes you can't justify
An agency wants £30,000 and four months for a first version. You just wanted to find out whether anyone would use it.
Tools that trap you
Most AI builders keep your app inside their platform. There's no real code, no way to hand it to a developer later, no way to ship it yourself.
A rewrite every time you ask
Ask for one small change and the tool rebuilds from scratch, losing everything you'd already got right.
How it works
Four steps. One conversation.
Describe it
Tell MoBuild what you want, the way you'd explain it to a friend. One screen or a whole app — it asks if it needs to know more.
Watch it get built
MoBuild writes the app in front of you. You see each screen appear as it goes, in plain English, not a wall of code.
Try it on a phone
Your app runs live in the browser in a phone frame, and on your actual phone when you want. Tap around the real thing, not a picture of it.
Ask for changes
"Make the button bigger." "Add a sign-up screen." MoBuild edits your app in place and remembers everything you've already decided.
Why MoBuild
Everything a developer would do, without the developer.
You describe. It builds, tests, fixes and ships.
Plain English, nothing to learn
There are no prompts to memorise. Say "add a settings screen with dark mode" and it's there.
Real screens on a real phone
Your app runs live while you build it. Nothing to install, no Mac, no simulator.
It remembers your app
Forty changes in, it still knows why you made the third one. It edits what exists instead of starting over.
A bad change can't break it
If something goes wrong, your last working version stays exactly where it is. MoBuild shows you what broke, in plain language, and fixes it.
The boring parts are handled
Sign-in, saving data, notifications, app icons, the App Store listing. You never set up a server or read a document about certificates.
You own it, properly
Every app is real React Native code in a repository that's yours. Take it to a developer any time. Nothing is locked in.
Ship it
We'll get you through App Store review.
This is the part everyone else leaves out. Getting an app onto the App Store means certificates, provisioning profiles, signed builds, icons at nine sizes and a listing that passes review. MoBuild does all of it. Your accounts and your keys stay yours.
Describe the icon, get every size
Say what it should look like. Pick from a few. MoBuild puts it in your app and generates every size iOS and Android ask for — there are more than you'd think.

A signed build in TestFlight
Connect your Apple account once. MoBuild builds and signs your app, prepares the listing and screenshots, and puts it in TestFlight so you can send it to people.

Ready for review
Published without touching a keystore
Connect your Google Play account. MoBuild builds a signed Android release with managed signing — nothing for you to generate, store or lose — and uploads it to your track.
Bloom Studio
Managed signing
Your Apple and Google accounts stay in your name. Your signing keys are yours. If you leave, your app goes with you.
Ownership
You own what you build.
Most AI app builders keep your app on their platform. Here's the difference.

Each of these started as a single line. You shape it from there by talking.

What it actually costs
Free right now. Here's what it costs after.
MoBuild is free while we're in beta — no card, no trial timer. When we do charge, you'll pay for the AI and the build machines that make your app, and nothing else. Two costs won't come from us, so you should know about them now:
Apple charges $99 a year for a developer account.
Everyone who publishes an iPhone app pays this, including us.
Google charges $25, once, ever for a Play Console account.
One payment, for the life of the account.
That's the whole list. If that changes, we'll say so here first.
