Primio: AI Flutter app builder for iOS and Android

Primio is a browser-based AI Flutter app builder for iOS and Android, with support for web apps and progressive web apps (PWAs). Describe your app in plain language, and Primio generates the Flutter code. You can then request changes to the design, add features and fix bugs through chat while checking the live preview.

Build and test without a local Flutter setup

Setting up a local mobile development environment means installing build tools, configuring emulators and managing release signing. That work can take time before you have an app to test.

Primio runs code generation, previews and production builds in the cloud. Android and iOS emulators are available inside the browser workspace, so you can test your app on a virtual phone or tablet without installing a local emulator.

The live preview and emulators serve different purposes. The preview runs a Flutter web version of your app for checking screens, layouts and navigation as you make changes. The emulators run compiled Android and iOS builds, letting you check platform-specific behavior and inspect runtime logs. Before release, you should still test on physical devices, particularly for features that use the camera, location or other hardware.

Create app store builds or export the code

Primio produces signed Android APK files for testing, AAB files for Google Play and iOS IPA files for TestFlight and App Store submission. After you connect your Apple credentials, it can also upload iOS builds to App Store Connect. You still need the relevant developer accounts and must complete the stores' submission and review steps.

You can also export the complete Flutter project on a paid plan. This includes the source code, assets and dependencies, so you can continue development locally, hand the project to a developer or use your own build pipeline. Code export is a snapshot: subsequent local changes do not automatically sync back to Primio.
