Some AI app builders produce iPhone apps and some do not, and it is worth asking before you start. App Builder Agent builds Android apps (a test APK, and a signed APK plus AAB for Google Play) and websites that work on iPhone in Safari; it does not produce an iOS app directly. The honest route to the App Store is to export the React Native or Flutter source on a paid plan, build it for iOS with Xcode on a Mac or a cloud Mac service such as Expo EAS, join the Apple Developer Program at US$99 a year, and go through App Store review. Many small businesses ship Android plus a website first and add iOS once the app has proved itself.
The question usually comes from one of two places: a business owner whose customers are half on iPhone, or a founder who wants to say "on the App Store" in the pitch. Both deserve a straight answer rather than a vague "cross-platform" badge. This guide explains what an AI app builder can and cannot do for iPhone, what Apple requires from anyone, the four realistic routes with their cost and effort, and how to decide which to take this month.
Why AI app builders and iPhone are complicated
Building an Android app is something a server can do: the code is compiled with open tools, signed with a key, and the result is a file you can install on any Android phone or upload to Google Play. Building an iPhone app is different in three ways, and none of them are about the AI.
- Apple's toolchain runs only on macOS. Xcode, the compiler and the signing tools require a Mac. Cloud services rent Macs for this, at a cost.
- There is no sideloading in the ordinary sense. An Android APK installs from a link; an iPhone app reaches phones through the App Store, TestFlight, or enterprise distribution, each of which needs an Apple developer account.
- Apple's program costs US$99 per year and involves review. Every submission is checked against App Store guidelines, and apps that are thin wrappers of a website are routinely refused.
App Builder Agent generates React Native (or Flutter) code, which is cross-platform by design, but the platform's build servers produce Android artifacts only. What you get for iPhone is the source, and the source is genuinely useful.
The four routes for iPhone users, compared
| Route | What you need | Cost (as of 2026) | Effort | Result |
|---|---|---|---|---|
| Website version (works in Safari, add to home screen) | A website project in App Builder Agent | Free plan or $1.49 Member plan | Minutes to an hour | Opens on any iPhone with no store; limited device features, no App Store listing |
| Export source, build with Expo EAS (cloud Mac) | Member plan or above for export; Expo account; Apple Developer Program | $1.49 plan, EAS free tier or a paid tier, Apple $99/year | A day or two for a first build; more if libraries need changes | A real iOS app, TestFlight and App Store submission |
| Export source, build with Xcode on your own Mac | Member plan or above; a Mac; Apple Developer Program | $1.49 plan, Apple $99/year | A day or two, plus learning Xcode if it is new to you | Same as above, with full local control |
| Hire a developer to finish the iOS version | The exported source; a freelancer with a Mac; Apple Developer Program in your name | Commonly a few hundred to a few thousand dollars; Apple $99/year | Your time: a few hours to brief and test | App Store app without learning the tools yourself |
Whichever route you choose, the Android side stays the same: the APK app builder produces the test APK and the signed store build, and the signed APK and AAB guide covers Google Play.
Route 1: a website version that works on iPhone today
For a booking page, a menu, a loyalty card, a dashboard or a content app, a website does most of what the app does and reaches every iPhone in the world in the next ten minutes. Add-to-home-screen gives it an icon and a full-screen look. What it cannot do: push notifications are limited, there is no App Store listing, and camera or Bluetooth features are restricted.
The practical pattern is to build the mobile app project for Android and ask the agent for a website project with the same screens, sharing the hosted backend so data stays in sync.
The PWA versus native app guide weighs this route in more detail for small businesses.
Route 2 and 3: export the source and build it for iOS
Source export is included on the Member plan and above. You download a complete React Native (or Flutter) project as a zip: the screens, the logic, the assets, ready to open in a normal development environment. From there the iOS path is the standard one every React Native or Flutter developer follows, and it is well documented.
- Join the Apple Developer Program (US$99 per year). Identity verification takes a day or two; organizations need a D-U-N-S number.
- Pick a bundle identifier, the iOS equivalent of the Android package id, such as
com.harborcafe.app. Register it in your Apple account. - Choose a build method. Expo EAS builds in the cloud on Apple hardware and handles certificates for you; you run a few commands from any computer. Xcode on a Mac gives you the same result locally. A rented cloud Mac is a third option if you want Xcode without owning a Mac.
- Add the iOS assets: an app icon set, a launch screen, and permission descriptions (the text iOS shows when the app asks for camera or location).
- Fix Android-only pieces. Occasionally the agent uses a library or a permission that has no iOS counterpart; the build log will tell you. Replace it or make it conditional.
- Test with TestFlight on real iPhones, then submit for App Store review. Provide reviewer credentials if the app has a login, and expect review to take from a day to about a week.
Before you export, ask the agent to check the project for iOS compatibility: "List any Android-only libraries, permissions or code paths in this project and replace them with cross-platform equivalents." It cannot build for iOS, but it can make the export cleaner.
Route 4: hand the source to a developer
If you do not want to learn Xcode or EAS, the exported project is a normal codebase that any React Native or Flutter freelancer can pick up. The brief is short: "Here is a working React Native app that ships on Android; build and submit the iOS version under my Apple account." Because the app already works, the job is configuration and testing rather than development, which is why it costs a fraction of building an app from scratch. Keep the Apple Developer account in your own name so the listing and the certificates belong to you. The app cost guide has hourly rates for the US, UK and EU.
How to decide this month
- Mostly Android customers, or you are not sure yet - ship Android and the website version now; revisit iOS when people ask for it. This is the majority of small business apps.
- Half or more of your customers are on iPhone and the app is the product - plan on the $99 program and an export-and-build route from the start, and keep the app free of Android-only features so the export stays clean.
- You need "on the App Store" for a pitch or a store window sticker - budget the developer route: a few hundred to a few thousand dollars plus Apple's fee, and two to four weeks including review.
- You just need iPhone users to be able to use it - the website version is enough, and it costs nothing extra.
Apps with accounts, a dashboard and settings are the ones people most often want on both platforms; the login and dashboard apps in the gallery show the shape that exports cleanly. Build it once for Android, put the website version up for iPhone the same day, and take the App Store step when the app has earned it.
Frequently asked
Does App Builder Agent build iPhone apps?
No. It builds Android apps (test APK, signed APK and AAB for Google Play) and websites that work on any phone. For iPhone you export the React Native or Flutter source on a Member plan or above and build it for iOS yourself with Xcode or a cloud service such as Expo EAS.
Do I need a Mac to make an iPhone app?
You need macOS with Xcode somewhere in the process. That can be your own Mac, a rented cloud Mac, or a hosted build service like Expo EAS that runs the Mac for you. Submitting to the App Store also needs an Apple Developer Program membership at US$99 per year.
Is the exported code ready for iOS?
React Native and Flutter are cross-platform, so the screens and logic run on iOS. Expect some work: installing the iOS dependencies, setting a bundle identifier, providing icons and splash screens, and fixing any Android-only library the agent used.
Can iPhone users use my app without the App Store?
Yes, as a website. A website project publishes at a link on appbuilderagent.com, opens in Safari, and can be added to the home screen as an icon. It cannot use every device feature, but for booking, ordering, dashboards and content it works well.
How much does an iPhone version cost?
Apple's program is US$99 per year, as of 2026. A cloud Mac or hosted build service is typically free to a few tens of dollars a month. Hiring a developer to finish and submit the iOS version commonly costs a few hundred to a few thousand dollars depending on the app.
