New · Flutter · Android · iOS

Native apps, written by AI, on the backend you already have.

One prompt writes the app and the website APIs it needs. Upload one ZIP; the files land in your folder, ready to open in your IDE.

Three platforms, one flow

Pick the one that fits your team.

FlutterAndroid + iOS from one code

Dart and Material 3. The best choice when you want both stores with one team. The website check runs the Dart analyzer rules on every module before it reaches your folder.

Needs: Flutter SDK 3.27+ · iOS builds on a Mac
AndroidKotlin + Jetpack Compose

A fully native Android app. Libraries and permissions the app needs are added to Gradle and the manifest by the import itself — open the folder in Android Studio and press Run.

Needs: a current Android Studio (Windows, Mac or Linux) · JDK 17
iOSSwiftUI, iPhone and iPad

A fully native iPhone app. New files appear in Xcode by themselves (Xcode synchronized folders); permission texts are written into the project by the import.

Needs: a Mac with Xcode 26 · an Apple Developer account
How it is built

The same way as a website: blocks in, a project out.

Copy the prompt

Studio → sidebar Flutter / Android / iOS → Copy prompt. Paste it into Claude or ChatGPT with your idea.

One ZIP, two parts

<platform>/ = screens and modules of the app · web/ = the tables, APIs and save rules it needs on your website.

Upload ZIP

Like a website: no project to create first — the app is made from the ZIP. Every block is checked; one mistake and nothing is written.

Files land in your folder

Only the changed files are written into the folder you chose. The code is also kept on Vybev, so nothing is lost when a computer is.

Run and publish

Open the folder in your IDE, run on a phone, build for Google Play or the App Store. Name, app ID and icons come from the Studio.

What every app gets

A fixed core the AI builds on — it never edits it.

Screens by nameGx.go("product", {id}) · bottom tabs · back · sign-in guard on screens that need it
Your website's accountsthe same /login/default as the web: one user list, one session
Data only through APIsGx.api("slug") → the API blocks written in web/ — the app never holds a database password
Realtimechat, live orders, who is online on gea-rt — a ticket from the website, no secret in the app
UI kit + themebuttons, inputs, cards, lists, loading / empty / error states, dark mode — colours from one THEME block
Permissions & librariestick camera, photos, files, QR, location, maps, push, notifications, Face ID / fingerprint, microphone, contacts, Bluetooth or share in Studio → 🔐 Permissions & libraries: the checked library versions, the Android permissions and the iPhone permission texts are written into the project; Firebase and Xcode steps are listed
Every app carries a signature made for your website's domain; the website refuses unsigned copies. A Flutter signature does not open the API to an iOS app, and the other way round.
An app needs a backend (Laravel or Python, with MySQL / PostgreSQL / MongoDB) plus the app package: React Native, Flutter, Android or iOS — $99 each (was $165), once per e-mail. Realtime gea-rt is an optional $99 add-on, only for chat or live screens. Pick them together on the pricing page and pay once. See pricing
Run it

From your folder to the store.

Flutter

bash
# once, in the folder the Studio filled:
flutter create . --platforms=android,ios
dart run tool/gx_brand.dart          # name, app ID, orientation from the Studio
dart run flutter_launcher_icons      # icons from your logo
flutter pub get
flutter run                          # a phone or an emulator

# store builds
flutter build appbundle             # Google Play
flutter build ipa                   # App Store (on a Mac)

Android

Steps
1. Android Studio → Open → the folder the Studio filled
2. Wait for Gradle sync (first time downloads the libraries)
3. Run on a phone or an emulator
4. Build → Generate Signed App Bundle → Google Play

# after each ZIP: Android Studio picks up the new files — press Sync if the library guide added a library

iOS

Steps
1. On a Mac: open GxApp.xcodeproj with Xcode 26
2. Target GxApp → Signing & Capabilities → Team = your Apple Developer team
3. Run on an iPhone or the simulator
4. Product → Archive → Distribute → App Store Connect

# Swift packages from the library guide: File → Add Package Dependencies

Build in the cloud (GitHub)

bash
# No Flutter SDK, Android Studio or Mac? Every project has .github/workflows/gx-build.yml:
git init && git add . && git commit -m "app"
git remote add origin https://github.com/<you>/<app>.git
git push -u origin main
# GitHub → Actions → green run → Artifacts: the APK / the iOS simulator app.
# A green run also proves the code compiles.

Questions

Before you start.

Which one should I pick?

Flutter if you want Android and iOS with one code. Android or iOS alone when you need the platform's own look, its newest features, or your team already writes Kotlin / Swift.

What about the existing App (React Native)?

It stays: it turns your website screens into an app. The native apps are written screen by screen by the AI for when you want a real native interface.

Can the app download new code later?

No — store rules forbid it. A new ZIP updates the project in your folder; you build and publish a new version, like any app.

Why does the website refuse my app?

The website only answers apps signed for its own domain. Save the name & logo in the Studio while your code signature is active.

How do push notifications get set up?

Tick Push in 🔐 Permissions & libraries: the Firebase libraries and the notification permission go into the project, and the Studio lists what only you can do — create the Firebase project, add google-services.json / GoogleService-Info.plist, and turn on Push Notifications in Xcode. Your website gets the API that sends them.

Do I need a Mac?

Only for iOS (Apple's rule). Flutter and Android work on Windows, Mac or Linux.
