iOS app builder
AI iOS app builder for native iPhone apps
Borel is an AI iOS app builder for native iPhone apps. Describe the app in plain words and Borel writes it in Swift with SwiftUI, compiles it with Xcode on its own Mac and runs it in the iOS Simulator in your browser, free. On Pro, Borel Companion puts it on your iPhone and Borel publishes it to the App Store. No Mac needed.

How it works
From an idea to an iPhone app in three steps
- 1
Describe it
Write what the app should do, the way you'd tell a friend. Borel plans the screens with you before it builds.
- 2
Watch it run
Borel writes the SwiftUI, Xcode compiles it on Borel's Mac, and the app opens in the iOS Simulator in your browser.
- 3
Install it or publish it
On Pro, Borel Companion puts it on your iPhone, and Publish sends it to the App Store under your own account.
What you get
What does Borel build?
A native iPhone app, written in Swift with SwiftUI, the language and framework Apple uses for its own apps. It isn't a website in a frame or a cross-platform layer: Xcode compiles it on Borel's own Mac for iOS 17 and later, and the same app runs on iPad.
Because the code is native, the app reaches the iPhone directly: Face ID, the camera, Apple Maps, haptics, reminders and in-app purchases, with the permission text iOS asks for written for you. The project is yours too. Download the Swift source on any plan, with an XcodeGen project.yml that opens in Xcode, and read more on the AI SwiftUI app builder page.
No Mac needed
Can I watch my app run without a Mac?
Yes. Every build opens in Apple's iOS Simulator, running on Borel's Mac and streamed live into your browser. You tap, type and scroll through the real app, and each change you ask for lands in it a moment later. It's free for everyone, on every plan.
That's what makes Borel work from any computer with a browser, a Windows PC included: Xcode and the simulator run on Borel's side. See it on the iPhone Simulator in your browser, or read how people build iPhone apps on Windows.
Your own iPhone
How do I put the app on my own iPhone?
With Borel Companion, a desktop app for Windows and Mac that comes with Pro. Plug your iPhone in once, and after that Companion installs each new version over Wi-Fi. You sign in with your own Apple ID, and a free one is enough for apps just for you: it holds three of your apps at a time, and Companion renews Apple's seven-day signature while it runs.
No App Store and no developer account needed for that. It's the way to keep a personal app on your home screen, or to try a build in your hand before you publish. The guide to installing without the App Store walks through it.
Publishing
How does the app get on the App Store?
On Pro, press Publish. Borel builds the app on its own Mac, signs it and uploads it to App Store Connect under your own account, so the app you send to Apple is the one you tested. Apple asks every App Store app for a membership in its Developer Program, $99 a year, paid to Apple.
You set the name the App Store shows and the app's icon in Borel, uploading your own or having the AI draw one. Publishing to the App Store in the docs covers every step, and there's a guide to publishing from Windows.
Built in
What comes built into every app?
The parts most apps need, already wired up, with no keys to paste and no services to sign up for. Ask for a feature in the chat and Borel connects it to your SwiftUI screens.
AI
Borel AI answers, summarises and writes inside your app, with no API key of your own.
Accounts
Sign-up and sign-in with email and password, so each person sees their own data.
Data
A cloud database Borel runs for you, so lists and records follow the account.
Storage
File storage for photos and documents people add to your app.
Compared
How does Borel compare with other app builders?
The question that decides the rest is what each tool writes. Borel writes native Swift; most AI builders write React Native through Expo, a web app, or Flutter. Here is what each makes, how you see it on an iPhone and how it reaches the App Store, from each tool's own site as of October 2026. Every App Store route also takes Apple's $99-a-year Developer Program.
Each has a longer page: Lovable, Bolt, Replit, FlutterFlow and a0.dev, or see AI app builders for iPhone, compared.
| Builder | What it makes | Seeing it on iPhone | App Store | Paid plans from |
|---|---|---|---|---|

| Lovable | Web apps | A web page | No built-in flow | $25 a month |
| Bolt | React Native, with Expo | Expo Go on your phone | From your own terminal | $25 a month |
| Replit | React Native, with Expo | Expo Go; a simulator on paid plans | Guided, through TestFlight | $20 a month |
| FlutterFlow | Flutter | A web version; a Mac for iOS | One click, on paid plans | $39 a month |
| a0.dev | React Native, with Expo | A web preview, or a0's own iPhone app | Uploaded for you | $20 a month |
Real builds
What does a real build take?
Four apps Borel built from a single sentence each, with what each run cost and how long it took from the prompt to a running app, the Mac's compile and launch check included. Each one has its own page in real builds, with the prompt and the screens.
| App | Credits | Prompt to running app | Code |
|---|---|---|---|
| Recipe book | 5 credits | About 5 minutes | 23 Swift files |
| Workout log | 5.44 credits | About 5 minutes | 30 Swift files |
| Monthly budget | 5.56 credits | About 5 minutes | 24 Swift files |
| Content idea tracker | 2.85 credits | About 3 minutes | 13 Swift files |
Pricing
What does it cost to build an iOS app with Borel?
Start free with 5 free credits a day, up to 30 a month, and the iOS Simulator is free for everyone. Every message uses credits based on its real AI cost, 1 credit for each $0.10, so a small change often uses part of a credit.
Pro starts at $20 a month for 100 credits, or $16 a month billed yearly, with larger credit tiers. It adds Borel Companion on your iPhone and publishing to the App Store. See pricing for every tier.

Frequently asked questions
A tool that makes iPhone apps without you writing the code by hand. Borel is an AI iOS app builder: you describe the app in a chat, and it writes the app in Swift with SwiftUI, builds it with Xcode and runs it in the iOS Simulator in your browser.
Yes. Every Borel app is native Swift and SwiftUI, compiled with Xcode on Borel's own Mac for iOS 17 and later. It isn't a web app inside a wrapper, so it uses Face ID, the camera, Apple Maps and haptics directly.
No. Xcode and the iOS Simulator run on Borel's Mac, and you work in a browser on Windows or a Mac. Borel Companion, for Windows and Mac, installs the app on your iPhone.
Yes. Borel's free plan gives 5 free credits a day, up to 30 a month, and the iOS Simulator is free for everyone, so you can describe an app and watch it run before you pay. Installing on your iPhone and publishing to the App Store come with Pro, from $20 a month.
Yes. On Pro, Borel builds, signs and uploads the app to App Store Connect from its own Mac, so you never need one. You need Apple's Developer Program, $99 a year, for the App Store.
Yes. You can download the Swift source on any plan, with an XcodeGen project.yml that opens in Xcode, and the app is published under your own App Store Connect account.
No. You describe what you want in plain words and ask for changes the same way. If you do know Swift, the code is standard SwiftUI you can read and change in Xcode.
Borel makes apps for iPhone, and the same app runs on iPad.
