Primio - AI App Builder

Primio

About this app

Primio is an AI app builder that turns a simple prompt into a real, native mobile app for iOS and Android. Describe what you want in plain English and Primio writes the code, builds the app, and gets it ready for the App Store and Google Play. No coding, no Mac, and nothing to install.

This is vibe coding for mobile. You stay in a chat, describe changes in your own words, and watch your app come together in a live preview while Primio handles the engineering.

How It Works
- Describe your idea in a chat, the way you would explain it to a person.
- Primio generates a complete app and shows you a live preview in seconds.
- Keep chatting to refine screens, features, and design until it is right.
- Build a signed app and publish it to Google Play and the App Store.

Real Native Apps, Not Web Wrappers
Primio builds with Flutter and compiles to native code for iOS and Android, so your app is fast and feels real instead of a website in a shell. You can also ship the same project to the web as a PWA.

Test On Real Devices
Run your app on real iOS and Android emulators streamed straight to your browser. Switch devices, capture logs, and try everything before you ship, with no Xcode and no Android Studio.

Designs That Do Not Look AI-Generated
Pick from a curated Design Library of polished styles so your app looks intentional and professional. Adjust colors, gradients, and layouts until the design matches your vision.

Build And Publish Without A Mac
Primio generates submission-ready binaries in the cloud:
- Signed AAB for Google Play
- IPA for the App Store, with optional upload to TestFlight
- PWA for the web

There are no certificates to manage, no Xcode, and no Android Studio. You can build and publish iPhone apps without ever owning a Mac.

Built To Keep You Moving
- Live preview as you build
- Automatic fixing of build errors
- One-tap rollback to undo changes
- Reference your own files and images directly in the chat
- Browse the top charts for inspiration and build something similar

Who It Is For
Founders, makers, designers, and anyone with an app idea who wants to build an app without learning to code. If you can describe it, you can build it.
