GenVibe is an AI Expo app builder: you describe an app in plain English and it scaffolds a real Expo (React Native) project, runs it live in a cloud sandbox, and lets you preview it on your own phone through Expo Go — no local toolchain to install.
Expo is the fastest way to build cross-platform apps, but the setup — the managed workflow, expo-router, native modules, EAS — is a lot to wire up by hand. GenVibe's AI agent handles the scaffolding and writes idiomatic Expo code, so you skip straight to a working app and shape it by chatting.
Most AI builders are web-only. GenVibe is built around Expo specifically, so the output is a genuine mobile project you own — one you can preview on-device today and take through the standard Expo release pipeline when you're ready to ship.
Why build on Expo with AI?
Expo gives you one codebase for iOS and Android, a managed workflow that handles the native plumbing, and the Expo Go client for instant on-device testing. It's the pragmatic default for React Native today — and it's exactly what GenVibe targets.
Pairing Expo with an AI agent removes the two slowest parts of a new project: the blank-page scaffolding and the boilerplate. You describe the screens and behavior; GenVibe generates the Expo project, installs dependencies, and boots it live so you see a running app, not untested code.
- One Expo codebase targets both iOS and Android from a single prompt
- expo-router file-based navigation, generated for you
- Standard managed Expo workflow — real, idiomatic code you can read and own
- Runs live in a cloud sandbox from any device, including your phone
Preview on your phone with Expo Go
The moment your project scaffolds, GenVibe runs it on a live Expo dev server. To feel it on real hardware, install the free Expo Go app and scan the QR code GenVibe shows — your phone loads the actual app with real gestures, scrolling, and native components.
Every change you make by chatting updates the running app, so you can iterate with your phone in one hand and the prompt in the other. It's the honest way to know whether an idea feels right on mobile before committing to a store build.
From Expo project to store build with EAS
Here's the boundary: for Android, GenVibe queues a signed APK/AAB on Expo Application Services (EAS) from the workbench, running on your own Expo account, and on a paid plan or credit pack it uploads that build to Google Play's internal testing track and drafts the listing and privacy policy. iOS builds you run through EAS yourself, and App Store Connect uploads stay with you and your own developer account for now.
Because the output is a conventional Expo project with no lock-in, the iOS hand-off is the normal one: run it through EAS Build, then submit with your own Apple developer account. GenVibe removes the hard part — turning an idea into a running, editable Expo codebase — and hands you a project you can ship through channels you already trust.
Example prompt to start with
Build an Expo app for tracking daily water intake. Use expo-router with a bottom tab bar (Today, History, Settings). Today shows a big progress ring and a "+250ml" button; History shows a weekly chart; Settings has a daily-goal input and a dark-mode toggle. Store data in Supabase with email login. Clean, mobile-native design with safe-area padding.

Frequently asked questions
What is an Expo AI app builder?
It's a tool that turns a plain-English prompt into a real Expo (React Native) project. GenVibe scaffolds the app with expo-router navigation, runs it live in a cloud sandbox, and lets you preview it on your phone via Expo Go — without writing the boilerplate or installing a native toolchain.
Does GenVibe generate a real Expo project?
Yes. GenVibe outputs a standard, idiomatic Expo project using React Native and expo-router — real code in real files you can read, edit, and take through the normal Expo pipeline. It is not a proprietary or locked-in format.
How do I preview my Expo app on my phone?
Install the free Expo Go app, then scan the QR code GenVibe displays. Your phone loads the live app directly, and every change you make by chatting updates it in real time.
Can GenVibe publish my Expo app to the app stores?
To Google Play, yes; to the App Store, not yet. GenVibe queues a signed APK/AAB on Expo's EAS service from the workbench, using your own Expo account, and you download it in-app. On a paid plan or credit pack, the Publish window uploads it to Google Play's internal testing track. iOS builds you run through EAS yourself. Your developer accounts stay your own, and because the output is a standard Expo project there's no lock-in.
Do I need to install Expo or a native toolchain?
No — the project runs in GenVibe's cloud sandbox, so you can build and preview from any device including a phone. For on-device testing you only need the free Expo Go app. Android store builds run on Expo's EAS service from inside GenVibe; iOS builds you run with Expo's EAS tooling yourself.
How much does GenVibe cost?
GenVibe is free to start with no credit card, so you can build a working Expo app on free credits first. Paid plans start from $12/month, and one-time credit packs start at $5 — see the pricing page.
