Rork

Rork builds mobile apps from a chat. You describe the app, the agent writes the code, runs it on a cloud iOS simulator or Android emulator next to the chat, and helps you ship it to TestFlight, the App Store or Google Play. It is aimed at founders who want a store-ready mobile app without writing it themselves.

New projects are native: SwiftUI for iPhone, Kotlin with Jetpack Compose for Android, and Vite + React for web apps, which Rork publishes to an address on rork.app. Rork used to generate Expo (React Native) apps; it stopped creating new Expo projects, though existing ones still build, publish and export. An iPhone app and an Android app are two separate codebases in one project, sharing a backend and a chat. Design mode proposes screens before any code is written, and Plan mode writes a plan before changing files.

When the app needs data, Rork can create Rork Cloud, a hosted backend with a database, per-user access rules and server-side functions (free while in beta), or connect your own Supabase or Firebase project. It also sets up RevenueCat subscriptions, sign-in, notifications and AI features. Every project is a codebase you can read; on a paid plan you can edit it by hand and sync it two-way with GitHub to keep working in Xcode, Cursor or any editor.

The free plan only designs: building a working app, editing code and exporting it need a paid plan. Pricing is by credits with no add-on packs, so when you run out you upgrade or wait for the monthly reset, and iOS builds and simulator sessions cost credits on top of the message. iPad, Apple Watch, Vision Pro, widgets and games need the Rork Max plan, and publishing still needs your own Apple or Google developer account.
