Android → iOS port · fixed price
I rebuild your existing Android app as a real iOS app in Swift and SwiftUI. AI-assisted for speed, every line reviewed by me. It reuses your backend, goes through App Store review, and the code is yours.
No. No tool turns an APK or a Kotlin codebase into an iOS app. Android apps are written in Kotlin or Java for Android’s UI frameworks; iOS apps use Swift with SwiftUI or UIKit. Converters and wrappers produce code you end up rewriting anyway. There are three real options: a native rewrite, Kotlin Multiplatform, or Flutter/React Native.
One person does the whole port, from the audit to App Store approval. You talk to the developer who writes the code.
I port the behaviour, not the code. Translating line by line copies Android habits into an iOS app. Documenting what the app does first gives you an app that feels native and works the same.
~3 weeks to App Store submission; Apple review usually adds 1–3 days. Review runs in Apple’s queue, outside my three weeks.
The Android stack has a direct iOS counterpart for almost every piece. This is the map I work from.
| Android | iOS | Note |
|---|---|---|
| Kotlin | Swift | Both are null-safe and expression-heavy, so the logic maps closely. |
| Jetpack Compose / XML views | SwiftUI | Declarative UI on both sides. Material components become iOS system controls. |
| Coroutines & Flow | async/await, AsyncSequence | Structured concurrency on both; Swift 6 also checks data races at compile time. |
| ViewModel + StateFlow | @Observable models | Screen state lives in a model the view observes. |
| Navigation Compose | NavigationStack | Typed routes on both. The Android back button becomes the iOS swipe back. |
| Room | SwiftData, Core Data or GRDB | GRDB in my own apps: plain SQLite, easy to test. |
| Retrofit / OkHttp | URLSession + Codable | Same endpoints, same JSON. No new backend work. |
| DataStore / SharedPreferences | UserDefaults, Keychain | Tokens and secrets go to the Keychain. |
| WorkManager | BGTaskScheduler | iOS decides when background work runs, so sync is designed around that. |
| Firebase Cloud Messaging | APNs | FCM can keep sending; on iPhone it delivers through APNs. |
| Play Billing | StoreKit 2 or RevenueCat | Products are recreated in App Store Connect. |
| Google Sign-In | Sign in with Apple, plus Google | Apps with social login must also offer a privacy-focused option (Guideline 4.8). |
All three work. Which one is right depends on your Android code and your team.
| Native port (Swift) | Kotlin Multiplatform | Flutter / React Native | |
|---|---|---|---|
| Your Android app | Stays exactly as it is | Refactored so logic moves into a shared module | Rewritten as well, for both stores |
| What is reused | Backend, API, assets and the app’s behaviour as the spec | Business logic, if it’s already separate from the UI | Backend and assets |
| Feels on iOS | Fully native | Native, with a SwiftUI front end | Close to native; platform details take extra work |
| Cost and time | Fixed, from €1,500, ~3 weeks to App Store submission | Depends on how clean the Android code is | A new app for two platforms |
| Later on | Two codebases to keep in step | One shared core, two UIs, Kotlin and iOS skills needed | One codebase for both stores |
| Best when | The Android app works and you want iOS fast without touching it | A large app with complex logic and an in-house Kotlin team | You’re redesigning anyway and want one codebase going forward |
If your Android code already keeps its logic apart from the UI and you have Kotlin developers, KMP can be the better choice. If you’re planning a redesign anyway, Flutter gives you one codebase. I build Flutter apps too, and I’ll tell you on the quote if a port isn’t what you need.
One fixed price per app, agreed before I start. Every tier, Larger included, starts with a written quote within 24 h, and includes the Swift/SwiftUI app, App Store submission, the source code and 30 days of free bug fixes after launch.
Apple Developer Program membership in your name, €99/year (US$99); running costs such as hosting, RevenueCat or API usage; and backend changes unless they’re in the quote.
Each answer points to a tier and the highest one wins: Small is up to ~10 screens with no login or payments, Standard up to ~25 with login and subscriptions, anything beyond is a custom quote.
My own apps, live in both stores. No client logos or testimonials here, just apps you can install on both platforms.
The 3.5 weeks are the iOS port alone; the months before that went into the Android app itself. Both apps share one Django API.
About 120 tasks in ten phases, reusing modules from the Hebrew iOS app. One pronunciation engine in Kotlin and Swift, checked against one golden test set.
You don’t need a Mac: I build and test on mine. You do need an Apple Developer Program account in your name or your company’s, at €99/year (US$99), so the app and its revenue belong to you. A company account needs a free D-U-N-S number, which can take a few days, so start early.
Yes. It’s SwiftUI with native navigation, swipe-back, system controls and Dark Mode. Your brand stays the same: colours, icons, copy and flows match Android, while Android-only patterns become their iOS equivalents.
Yes, as it is, within the fixed price: REST, GraphQL, Firebase or Supabase. The iOS app talks to the same API as Android, so users and data are shared. If the backend needs changes, that part is quoted separately.
Your Play Billing products are recreated in App Store Connect and implemented with StoreKit 2, or with RevenueCat if you already use it (I do, in my own apps). With RevenueCat or your own backend, a subscriber keeps access on both platforms.
You do. The source goes into your Git repository and the app lives in your Apple Developer Program account. No licence fee and no lock-in: any iOS developer can take it over.
The Play Store link to start. For the build: read access to the Android repository, API docs or a test account, and your Apple Developer Program account with me added as a team member.
Yes, if you want it: a monthly plan for iOS updates, fixes and small features. Or hand the code to your own team; it comes documented and tested.
A Flutter or React Native app already runs on iOS, so there the job is adding the iOS target: platform setup, plugins, signing and the App Store release. That’s usually smaller than a port. Send the link and I’ll quote it.
No. An APK contains compiled Android code and resources; an iPhone can’t run it, and no converter turns it into a maintainable iOS app. App builders wrap websites, not native Android apps. AI coding tools help a developer rewrite faster, and I use them, but someone still has to build, test and ship the app.
Paste the link and anything I should know: backend, payments, deadline. You get scope, price and dates in writing. If KMP or Flutter suits you better, I’ll say so.
